Small amounts of antibiotic have been found in breast milk for all cephalosporins that have been studied, so the presence of cefditoren in milk should be expected. Uneasy sleep was noted in the breastfed infant starting about 2­3 days after initiation of drug therapy. The exposure appeared to be associated with a decrease in infant motor development at 1 year of age. The binding of dasatinib and the active metabolite by human plasma proteins is high, about 96% and 93%, respectively (1). If used near delivery, the newborn infant should be closely monitored for 24­48 hours for signs and symptoms of -blockade. In eight cases, the antidepressant had also been taken during pregnancy and three of these infants had the highest plasma concentrations of fluoxetine. The findings of pericardial effusion and cardiac tamponade in the infant were also thought to represent clinical evidence of a lupus-like syndrome (20). In 31 infants with severe reduction deformities born over a 4year period, none of the mothers remembered taking haloperidol (11). In the case described in the Fetal Risk Summary, the mother exclusively breastfed her infant and, on day 32, milk and plasma samples (peak and trough) and a peak infant plasma sample were obtained (2). The molecular weight (about 462 for the dihydrochloride salt) is low enough that transfer to the fetus should be expected. The molecular weight (about 295) and moderately long elimination half-life suggest that the drug will be transferred to the embryo­fetus. Only the latter anomaly is a potential drug effect, but the most likely cause was thought to be the result of an in utero fetal vascular accident or infection (11). Paper Presented at the 18th Interscience Conference on Antimicrobial Agents and Chemotherapy, Atlanta, Georgia, October 1­4, 1978. A 2001 prospective cohort study, conducted from 1986 to 1993 at five maternity hospitals, was designed to determine if anticonvulsant agents or other factors. Cephalosporins are usually considered safe to use during pregnancy (see other cephalosporins for published human experience). Therefore, if indicated, the maternal, and possibly the embryo­fetal, benefit of therapy appear to outweigh any unknown direct or indirect risks (2). The authors of the above report also cited a study that had been presented at a scientific meeting (3). Finnegan scores were consistently less than 4 by day 4 and, at 96 hours of age the infant had no signs of opioid withdrawal. The authors concluded that chronic alcohol ingestion may have enhanced fetal lung maturation (57). Marijuana is contraindicated in pregnancy (see Marijuana) but that product is usually smoked, whereas dronabinol is taken orally. Anticoagulant therapy in the prevention of placental infarction and perinatal death. If a woman is pregnant or conceives during treatment, she should be informed of the potential risk to her embryo and/or fetus. The effect of dobutamine hydrochloride on ventricular function and oxygen transport in patients with severe preeclampsia (abstract). Role of sublingual administration of tablet buprenorphine hydrochloride on relief of labour pain. A 1984 report described a 21-year-old woman with diffuse histiocytic lymphoma who received carmustine and procarbazine for 5 months before conception and throughout the first 24 weeks of pregnancy (4). Goldenseal has been used for hundreds of years and is one of the five topselling herbal products in the United States (2). Two reports have described the use of bisphosphonates before or during six human pregnancies. Because clinical significant concentrations are unlikely, the drug should be compatible with breastfeeding. Skeletal variations (incomplete ossification of the sternebrae, skull, and nasal bones) were observed at all doses. The antibody fragments probably do not cross, at least early in pregnancy, because of their high molecular weight (about 46,000), but some antibodies are able to cross the placenta in the 3rd trimester. Gabapentin exposure in human pregnancy: results from the gabapentin pregnancy registry. Plasma protein binding of estazolam is high (93%) and the range of estimated elimination half-life varies from 10 to 24 hours (1).

Inhaled corticosteroids play an important role in preventing acute exacerbations of asthma. When the breast ulcer became infected, a bilateral simple mastectomy was performed. A 2005 study described the use of gabapentin during pregnancy in five women, three of whom breastfed their infants (7). The dose was increased to 25 mg 3 times daily 4 days before the wholly breastfed 8-week-old infant was found pale, limp, and near respiratory arrest. The product was reformulated in 1976 to eliminate dicyclomine because that component was not found to contribute to the antiemetic effectiveness. Urinary sodium and potassium levels in the treated newborns were significantly greater than in the nonexposed controls. Clinical and laboratory survey into the oxytocic effects of dimenhydrinate in labor. Except for one study involving chick embryos, there are no published animal reproductive studies. Diuresis was found more often in newborns exposed to furosemide shortly before birth than in controls (11). At the highest dose (twice the dose that produced reductions in maternal weight gain), intrauterine growth restriction was also observed. For all groups, scores were the lowest at 2 hours, but no significant differences were measured between the groups (15). The newborn had Apgar scores of 8 and 9 at 1 and 5 minutes, respectively, but was hypotensive (mean arterial pressure 34­39 mmHg), mildly hypotonic, hypoglycemic, and fed poorly. Neonatal hyperbilirubinemia, suspected of being due to displacement of bilirubin from albumin-binding sites, has been attributed to the use of dapsone during gestation (13). The woman received everolimus, cyclosporine, and corticosteroids throughout pregnancy. On the 3rd day after delivery, the 1190-g female infant also developed a profound leukopenia with neutropenia, 10 days after in utero exposure to the antineoplastic agents. The molecular weight (about 228) and lack of plasma protein binding suggest that the drug will be excreted into breast milk, but the very short terminal-phase half-life will limit the amount excreted. No other adverse effects in infants exposed to ethosuximide from milk have been reported. Fesoterodine is indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency. There are human pregnancy data for imatinib, a drug in the same subclass and with the same mechanism of action as dasatinib. Ginger 1 g/day was compared with placebo for 4 days starting at a mean gestational age of about 10 weeks. A 23-year-old, 70-kg woman in her 12th postpartum week was treated for postnatal depression with fluvoxamine, 100 mg twice daily (2. A female infant with multiple congenital malformations was delivered from a woman who had used a proprietary preparation containing ergotamine, caffeine, belladonna, and pentobarbital during the 2nd month of pregnancy for migraine (14). A number of reports have described the safe use of atracurium during human pregnancy (9­13). The use of glyburide in all phases of human gestation has been reported in other studies (15­19). It is available in various topical formulations, such as creams, ointments, gels, and solutions in concentrations of 0. This same group reported in 1989 that infants who had been exposed to cocaine throughout pregnancy (N = 52) (average maternal dose/use = 0. Regardless, mothers taking hydrocodone products while breastfeeding should observe their infants for breathing difficulty, sedation, excessive sleepiness, gastrointestinal effects, and changes in feeding patterns. Extensive neonatal testing up to 3 days after delivery failed to discover any adverse effects of the drug. Anticoagulant-therapy in the prevention of placental infarction and perinatal death.

Antenatal use of enoxaparin for prevention and treatment of thromboembolism in pregnancy. The infant had normal weight, length, and head circumference but was markedly hypotonic at birth. Although the absence of human pregnancy experience prevents a more complete assessment, the very low systemic bioavailability, and the human experience with other agents in the antihistamine class, suggests that there is little if any embryo or fetal risk from epinastine. In neither case was evidence found to suggest a relationship to large categories of major or minor malformations or to individual defects. A 1998 review concluded that the risk of embryo­fetal harm was low when small doses were used, such as those for vaginal fungal infections (16). The initial treatment occurred during the 1st trimester, followed by treatments approximately 2 weeks before delivery at term and after cessation of breastfeeding. She responded well to the antifungal therapy and gave birth at 39 weeks to a healthy 2. Prevention of group B streptococci transmission during delivery by vaginal application of chlorhexidine gel. In a surveillance study of Michigan Medicaid recipients involving 229,101 completed pregnancies conducted between 1985 and 1992, 647 newborns had been exposed to clindamycin during the 1st trimester (includes both maternal systemic and nonsystemic administration) (F. Although the molecular weight is high (about 147,000), belimumab crossed the placenta late in gestation in cynomolgus monkeys as expected for an immune globulin antibody (2). The incidence of withdrawal in infants of the cocaine-only group was 25% (28 of 114) vs. The molecular weight (about 348) is low enough that transfer to the fetus should be expected. Other fetal complications, in addition to the arrhythmia, were polyhydramnios, ascites, pericardial effusion, cardiomegaly, and tricuspid and mitral valve regurgitation. Two abstracts described two pregnancies terminating with newborns exhibiting characteristic patterns of captopril-induced fetotoxicity and malformations (24,25). In a large retrospective Finnish study, the use of opiates (mainly codeine) during the 1st trimester was associated with an increased risk of cleft lip and palate (6,7). On day 15, levels at 0 and 11 hours were below detection, while those at 4 and 7 hours were 27 and 10 ng/mL, respectively. No additional therapy was given for 12 months until progressive disease was found and erlotinib 100 mg/day was started. The second and third cases, both involving the same woman, were published in 2000 (6). Epoetin alfa crosses the placenta in significant amounts to the fetus in pregnant mice (2) but not from the mother to the fetus (3) or from the fetus to the mother in sheep (4). Because neonatal hypoglycemia is a potential effect, women taking glimepiride should consider changing to insulin therapy while nursing. Some of these tumors (pancreatic acinar adenomas and testicular interstitial cell tumors) were also seen in a second strain of rats at lower doses (1,2). Much of this and earlier experiments were reviewed by these investigators in a 1957 paper (4). In another report, didanosine was given to pregnant mice in doses ranging from 10 to 300 mg/kg/day, through all or part of gestation, without resulting in teratogenic effects or other toxicity (2). Commercial plantations of ginkgo trees in the United States, however, are pruned to shrub height to allow mechanical picking of the leaves (6). Four weeks later, at 27 2/7 weeks, an emergent cesarean section for placental abruption delivered a viable female infant with Apgar scores of 5 and 7. Citalopram and demethylcitalopram in human milk; distribution, excretion and effects in breast fed infants. Although the plants are different, the main chemicals in the flower heads are the same: chamazulene, apigenin, bisabolol, and angelic acid (1). Systemic absorption may occur from mucous membranes or from damaged skin with the amount absorbed dependent on the administered dose. Other topical agents in addition to glycolic acid, such as antioxidants, tretinoin, and fluocinolone (a corticosteroid), are sometimes combined with hydroquinone to increase the efficacy of melasma treatment (14,15). No increased risk of birth defects with oral doses of 150 mg or 300 mg was found in the 7352 exposed pregnancies (prevalence 2. Following a 4-hour infusion, the amounts of bupropion in the maternal and fetal circulations and in the placenta were 32%, 20%, and 48%, respectively.

Other features that may be present are as follows: Birth weight <10th percentile for gestational age Eye defects (blindness, optic atrophy, microphthalmia) when drug also used in 2nd and 3rd trimesters Hypoplasia of the extremities (ranging from severe rhizomelic dwarfing to dystrophic nails and shortened fingers) Developmental retardation Seizures Scoliosis Deafness/hearing loss Congenital heart disease Death the critical period of exposure, based on the work of Hall and coworkers (2), seems to be the 6th­9th weeks of gestation. At 6 months of age, the infant was well with normal neurodevelopmental testing (15). Higher rates of jaundice, respiratory distress syndrome, and low Apgar scores were also found. For the cis isomer, the mean milk concentration over a 24-hour period ranged from 0. It is indicated for reducing the signs and symptoms and delaying structural damage in moderate to severe rheumatoid arthritis, including juvenile arthritis. However, the poor systemic bioavailability after recommended oral doses suggests that little will reach the maternal circulation and be available to expose the embryo­fetus. Although appropriate precautions had been taken to exclude and prevent pregnancies during clinical trials, three women conceived shortly after enrolling and all received a single 3-g oral dose of fosfomycin (H. Experimental production of congenital cleft palate: genetic and environmental factors. The drug has been suspected of having cytogenetic effects in human lymphocytes (2). However, the passage of this agent and its active, long-acting metabolite into milk should be expected (see also Diazepam). Until human data are available for dexmethylphenidate, the safest course is to avoid the drug in pregnancy. It is indicated for the treatment of postmenopausal women with osteoporosis at high risk for fracture or for patients who have failed or are intolerant to other available osteoporosis therapy. A woman was treated for endometriosis with a total danazol dose of 81 g divided over 101 days. Congenital anomalies in children of patients who received chemotherapy for cancer in childhood and adolescence. Entacapone is nearly completely metabolized and elimination is biphasic with elimination half-lives of 0. The use of warfarin to treat a deep vein thrombosis associated with circulating lupus anticoagulant during pregnancy has been described (24). No relationship between low birth weights or short gestation and caffeine was found after controlling for smoking, alcohol intake, and demographic characteristics. Treatment of fetal supraventricular tachycardia with flecainide acetate after digoxin failure. The defects with positive associations involve the heart and great vessels, limbs, skull, genitourinary system, feet, abdominal wall, small bowel, and muscles. Assuming that the milk contained a steady concentration of 120 ng/mL of fluoxetine and norfluoxetine, and the infant was ingesting 150 mL/kg/day of milk, the maximum theoretical infant dose was 15­20 mcg/kg/day. Fetal distress occurred 1 week later and the 1700-g female infant was delivered by emergency cesarean section with Apgar scores of 2 and 6 at 1 and 5 minutes, respectively. Hickman catheter use in a pregnant patient requiring therapeutic heparin anticoagulation. It also is indicated for locally advanced or metastatic adenocarcinoma of the pancreas. It is an oral, semisynthetic cephalosporin antibiotic similar to other agents in this class. It is in the same subclass of gadolinium-based contrast agents as gadobenate dimeglumine, gadodiamide, gadofosveset trisodium, gadopentetate dimeglumine, and gadoteridol. A retrospective cohort study using data from Tennessee Medicaid included 30,049 infants born in 1985­2000 was published in 2009 (16). In contrast, other studies have not confirmed a relationship with increased defects or mortality (4­8). The relatively low molecular weight (about 276), however, suggests that exposure of the embryo­fetus will occur. The American Academy of Pediatrics classifies fentanyl as compatible with breastfeeding (19). One group of investigators classified the risk to the fetus from exposure to flurazepam as "none­minimal," but the quality of the data was judged to be "poor" (2).

However, in one report, a mother taking 5 mg/day for a pituitary tumor was able to breastfeed her infant successfully (3). A review on the effect of various flavors in milk concluded that it was not known whether flavors such as garlic in milk had any effect on the subsequent development of food habits or willingness to accept new foods at weaning or later in life (15). In another study, 12 women with methotrexate-resistant gestational trophoblastic disease were treated with etoposide (100 mg/m2/day Ч 5 days every 10 days) (14). In pregnant rats, glyburide crossed the placenta to the fetus (fetal:maternal ratio 0. The amounts of caffeine in breast milk after maternal ingestion of caffeinated beverages are probably too low to be clinically significant. Among exposures in the 3rd trimester, there were no defects in 51 live births and 1 fetal death. Metabolism of carbidopa [L-(-)-hydrazino-3,4-dihydroxy-methylhydrocinnamic acid monohydrate], an aromatic amino acid decarboxylase inhibitor, in the rat, dog, rhesus monkey, and man. A 40-year-old woman, 14 days postpartum, was unsuccessfully treated with diltiazem, 60 mg 4 times/day, for resistant premature ventricular contractions. Although partial digestion of the antibody in the gastrointestinal tract is probable, the effect on a nursing infant from this exposure is unknown. Uterine curettage performed 7 days later confirmed the presence of an incomplete spontaneous abortion (51). This dose produced plasma drug concentrations similar to those achieved in humans given 600 mg/day. Bar-Oz B, Weber-Schoendorfer C, Berlin M, Clementi M, Di Gianantonio D, de Vries L, De Saints M, Merlob P, Stahl B, Eleftheriou G, Manakova E, Hubickova-Heringova L, Youngster I, Berkovitch M. Both preparations are indicated for the acute treatment of migraine headaches with or without aura. Intravaginal administration of hexachlorophene in pregnant rats resulted in frequent microphthalmia, anophthalmia, wavy ribs, and less frequently, cleft palate in the offspring (10,11). Good control of her spasticity was obtained with 140 mcg/day throughout her pregnancy. However, other investigators have questioned whether this study has accurately assessed the total caffeine intake of the women (19,20). Because of the increased sensitivity of newborns to antihistamines and the potential for adverse reactions, the manufacturer considers cyproheptadine to be contraindicated in nursing mothers (3). Cholestyramine also binds fat-soluble vitamins, and long-term use could result in deficiencies of these agents in either the mother or the fetus (8). Use of the drug in pregnant rats produced fetal growth restriction and, in two fetuses, incomplete skull ossification (1). A 1986 review explored this topic in depth and concluded that cigarette smoking adversely affects the ability to conceive during a given menstrual cycle. A 1994 report described the in vitro placental transfer, using a single cotyledon human placenta, of four oral hypoglycemic agents (4). Cord serum bromide concentration: variation and lack of association with pregnancy outcome. These levels were within the range (1­5 ng/mL) required to inhibit the growth of Mycobacterium tuberculosis (9). In another study of six women with severe preeclampsia and oliguria, lowdose dopamine infusion produced a significant rise in urine and cardiac output (5). The degree of hirsutism was age related, with the mean ages of severely and mildly hirsute women being 28. Owing to the above case report, the American Academy of Pediatrics states that the drug should be used with caution during breastfeeding (4). Sedation and poor sucking were observed in seven infants, six of whom had been exposed in utero to phenobarbital or primidone. Retinopathy of prematurity-like fundus and persistent hyperplastic primary vitreous associated with maternal cocaine use. The author concluded that baclofen could produce spina bifida or other neural tube defects in rats.

There were three stillbirths among the 107 infants: one twin; one after intrauterine infection (no fungus recovered); and one death in utero. Eleven (52%) of the exposed infants had major or minor congenital malformations compared with six (15%) of the controls. Because of very rapid absorption, hexachlorophene should not be used on mucous membranes or injured skin (1,2). Moreover, the case reports below provide indirect evidence that botulinum toxins do not cross to the fetus in clinically significant amounts. Another important finding of this study was the independent association between the risk of major anomalies and poor glycemic control in early pregnancy. The authors of this report then described the outcomes of 31 women studied prospectively after exposure to home appliances with 110 V (N = 26) or 220 V (N = 2), or to high voltage (2000 and 8000 V) from electrified fences (N = 2), or to a lowvoltage (12 V) telephone line (N = 1). A number of other studies have reported the use of filgrastim in human pregnancy (8­12). The incidence of congenital heart disease per 1000 births in smokers and nonsmokers was 7. The succinimide anticonvulsants have been considered the anticonvulsants of choice for the treatment of petit mal epilepsy during the 1st trimester. Twelve other cases of hypocalvaria or acalvaria were reviewed, three of which were thought to be caused by captopril (N = 2) or enalapril (N = 1) and nine others with causes that were either not drug-related or unknown. Nine weeks later, recurrence of tumor growth necessitated delivery of the normal infant by cesarean section to allow for more definitive treatment of the tumor. Epidemiologic analysis of prenatal exposure to cough medicines containing dextromethorphan: no evidence of human teratogenicity. A 1988 review cited a number of studies investigating the possible association between occupational exposure to anesthetic gases and adverse pregnancy outcomes (15). Natural history of the fetal alcohol syndrome: a 10-year follow-up of eleven patients. Because of the limited human pregnancy experience with atypical antipsychotics, the American College of Obstetricians and Gynecologists does not recommend the routine use of these agents in pregnancy, but a risk­benefit assessment may indicate that such use is appropriate (2). However, in a third assay, fospropofol was mutagenic in the presence of metabolic activation but the finding was thought to have been an artifact of the culture conditions (1). In some series, all of the mothers and newborns had hyperglycemia without ketoacidosis (14). It is not known if glimepiride crosses the placenta, but the molecular weight (about 491) is low enough that transfer to the fetus should be expected. The first published report on the use of epoetin alfa in human pregnancy appeared in a 1990 abstract (20). There was no significant difference in the rate of asthma exacerbations between the groups, but significantly fewer discontinued beclomethasone because of adverse effects. In another study of 55 infants exposed to cocaine (with or without opiates), one infant with perinatal asphyxia had a cerebral infarction (18). In an investigation comparing 1427 malformed newborns with 3001 controls, 1st trimester use of narcotic analgesics (most commonly codeine) was associated with inguinal hernias, cardiac and circulatory system defects, cleft lip and palate, dislocated hip and other musculoskeletal defects. The relatively low molecular weight (about 382 for the free base) and the prolonged elimination half-lives of the parent drug and major active metabolite suggest that the drugs will be excreted into breast milk. Neonatal bromide intoxication: prenatal ingestion of a large quantity of bromides with transplacental accumulation in the fetus. Moreover, when caffeine consumption was further subdivided, a partial dose­ response relationship was observed, with a ratio of 0. Although fertility studies have not been conducted, no effects on reproductive tissues were noted during 28-day repeat-dose toxicity studies in rats and monkeys or in 6-month rat and 9-month monkey chronic toxicity studies (1). An ultrasound examination revealed normal amniotic fluid volume but no fetal breathing, body motion, or tone. The hypercalcemia was caused by the milk-alkali syndrome and resulted in pancreatitis and azotemia. In addition, a report has described a successful pregnancy in a woman with aplastic anemia who was treated with bone marrow transplantation (15).

Cialis sublingual 20 mg overnight delivery

Mild preeclampsia developed at 32 weeks after four of the planned six cycles had been given. Bendamustine is metabolized to two minor active metabolites (M3 and M4) that have low plasma concentrations (10% and 1% of the parent compound concentrations, respectively). The herb has been used safely as an antiemetic for nausea and vomiting of pregnancy. Commenting on their results, the investigators thought that recall bias was unlikely because they did not observe increased risks for other malformations, and it was unlikely that the mothers would have known of the suspected association between corticosteroids and orofacial clefts (35). She had irregular uterine contractions and her cervix was dilated 1 cm, 50% effaced. A prospective, multicenter cohort study of 78 women (81 outcomes, 3 sets of twins) who had 1st trimester exposure to calcium channel blockers, including 1% to felodipine, was reported in 1996 (2). Although not specifically stated for these three women, mean serum concentrations in fasted adults after a 200-mg dose were 2. It binds reversibly to serum albumin, resulting in longer time in the vascular system than non-protein-binding contrast agents. A double-blind comparison of butorphanol and meperidine in labour: maternal pain relief and effect on the newborn. Because of the small numbers, a dose response could only be conducted with paroxetine. Although retrospective reports are usually biased, reporting adverse outcomes and not normal infants, nine of the defects involved the heart and great vessels. Specific data were available for six defect categories, including (observed/expected) 1/2 cardiovascular defects, 1/0. Psychomotor development was normal at 1 year of age, but physical growth remained restricted (3rd percentile). In a retrospective analysis of the pregnancy outcomes among nurses who had washed their hands with hexachlorophene during the 1st trimester, 25 severe malformations were observed in 460 neonates (15). Ginseng can affect multiple organ systems in users and, potentially, could adversely affect a nursing infant if the ginsenosides (active constituents) were excreted into breast milk. The agent is not teratogenic or embryotoxic in mice, rats, and rabbits given doses up to 20 times the human dose (1). Severe chronic neutropenia: treatment and follow-up of patients in the Severe Chronic Neutropenia International Registry. Folic acid and vitamin B 12 levels in pregnancy and their relation to megaloblastic anemia. When pregnancy was diagnosed, diazepam was discontinued but, without the drug, her muscle spasms increased and baclofen (30 mg/day) was started. Amniotic fluid and maternal and cord serum levels of gentamicin after intra-amniotic instillation in patients with premature rupture of the membranes. No increase in malformations was observed in rats given Bendectin (two-drug combination) during organogenesis in doses of 0, 200, 500, and 800 mg/kg/day (3). The infant did well and her psychophysical development was normal at 20 months of age. Maternal and fetal and tissue levels of, ceftriaxone following preoperative prophylaxis in emergency cesarean section. Defects observed in four of the infants are shown in the list below, and three other infants are described in the text that follows: Flattened nasal bridge, palate defect, skin tag, four toes each foot, hypoplastic middle phalanx fifth finger, bilateral inguinal hernia sacs Toes missing, single coronary artery Hemangioma, umbilical hernia Imperforate anus, rectovaginal fistula, growth restricted A newborn exposed in utero to cyclophosphamide during the 1st trimester presented with multiple anomalies (6). Many investigators now consider diuretics contraindicated in pregnancy, except for patients with cardiovascular disorders, since they do not prevent or alter the course of toxemia and they may decrease placental perfusion (35­38). However, other studies in much larger exposed populations have not observed disturbances of menstruation or excessive hair growth (36). Mid-trimester metronidazole and azithromycin did not prevent preterm birth in women at increased risk: a double-blind trial. The effect of in utero exposure to antiepileptic drugs on fetal growth was described for 977 newborns in another 2000 Swedish study (37). Cocaine exposure for this analysis was based on self-reported use any time from 1 month before conception through the first 3 months of pregnancy (52,53). The investigators concluded that the use of dextromethorphan during the 1st trimester was not associated with an increase in congenital defects (11). It is metabolized to four pharmacologically active metabolites, all of which occur in human plasma at a much lower concentration than the parent drug. Published reports describing the use of disulfiram in gestation involve 36 pregnancies (2­9).

Chronic renal failure

Two of the women developed polyhydramnios after starting treatment with epoetin alfa, and all developed preeclampsia or worsening renal impairment, but the authors could not determine whether these were effects of the drug treatment or the underlying disease (7). However, the indicated uses for the drug and the very short elimination half-life (2. A 1993 report described the use of buspirone, in combination with four other agents, all started before conception, in a pregnant woman with major depression, a coexisting panic disorder, and migraine headaches (2). Caffeine consumption during pregnancy and association with late spontaneous abortion. If a woman taking this therapy is breastfeeding, her nursing infant could be exposed to all three agents. At 36 weeks, she underwent a planned cesarean section for a healthy infant (no further details on the newborn were provided) (2). The 2635-g infant (sex not specified), delivered 2 weeks preterm by cesarean section, showed no signs or symptoms of withdrawal after birth. Nevertheless, the botanical drug is minimally absorbed, so clinically significant exposure of the embryo­fetus probably does not occur. A 2003 review stated that a topical product containing fluocinolone, hydroquinone, and tretinoin (Tri-Luma ) was effective for the treatment of melasma, a localized facial hyperpigmentation also known as the "mask of pregnancy" (6). Sixteen livebirths occurred in the exposed group compared with 36 in controls (21). There were 627 outcomes exposed to didanosine (370 in the 1st trimester and 257 in the 2nd/3rd trimesters) in combination with other antiretroviral agents. The effects observed on motor activity, startles, and heart rate variability were not significant after adjustment (8). Transfer of Timentin (ticarcillin and clavulanic acid) across the in vitro perfused human placenta: comparison with other agents. There were 288 infants with birth defects among 10,803 live births with exposure anytime during pregnancy (2. The relationship between folic acid levels and various maternal or fetal complications is complex. If a woman is inadvertently exposed to the drug during the 1st trimester, she should be informed of the potential risk. Although none of the mothers was injured or even lost consciousness, in these otherwise harmless events, fetal death occurred in 10 (71%). The manufacturer states that diclofenac is excreted into the milk of nursing mothers but does not cite quantitative data (5). However, several studies have found that the drug crosses the human placenta and have described the pharmacokinetics in pregnancy. Other benzodiazepines accumulate in human milk, and adverse effects in the nursing infant have been reported (see Diazepam). When administered alone, neither form of diatrizoate has been associated with suppression of the fetal thyroid. Although human pregnancy experience is needed, the drug probably is compatible in pregnancy. At 20 months of age, he was nearly totally blind (probable optic atrophy) and developmentally slow. A significant hyperglycemia occurred within 15­30 minutes but, in contrast to neonatal lambs, did not induce a significant ketogenesis. The results of three other studies, one conducted in 12 Irish hospitals beginning in 1981 (53), one in Spain between 1974 and 1990 (54), and one in the United States and Canada from 1988 through 1991 (55,56), indicated that folic acid may be protective at a much lower dosage. The pregnant rats were given 20 mg of methylmercuric chloride on gestational day 7 and then treated with either 0. The molecular weight (about 108) is low enough for excretion into milk, but the plasma concentrations after topical use of the lotion are very low, if at all. The case above that observed seizures may or may not have been related to bupropion. Of the 2048 women, from a total sample of 104,339, who had received benzodiazepines, 80 had received 10 or more prescriptions for these agents. The latest data indicated that in women who had used cocaine during pregnancy (N = 75; 23 of whom used cocaine only during the 1st trimester), 10 (13. Because of their own and previously published findings, they further recommended that the focus of future studies should be on malformations involving the abdominal wall and urogenital system, and limb reduction defects. However, the fetal risk from treatment of refractory fetal arrhythmias appears to be low.

Hyperornithinemia

Administration of furosemide to women during confinement, and its action on newborn infants. The duration of hospitalization was significantly longer in exposed premature than in nonexposed premature infants, 14. A second 1991 publication involved a 37-year-old woman who was treated throughout pregnancy with escalating doses of epoetin alfa (22). Milk and infant urine samples collected 66 hours after the last dose yielded gold levels of 22 and 0. Within about 7­10 days, the white blood cell count had returned to normal in both infants. Consistent with the molecular weight (about 327), clozapine crosses the placenta, at least at term. The male infant was small for gestational age (1878 g), was cyanotic, and had a poor tone. Although the elimination half-life from bone is not known with certainty, the clearance from bone in animals is up to 165 days (1). In a 1982 study, the infants of mothers who had received analgesia before vaginal delivery consisting of either enflurane, nitrous oxide (both mixed with oxygen), or no inhalation agent were evaluated for neurobehavior during the first 24 hours (15). However, because of the second case in the same mother and the third infant, the defects were now thought to represent the teratogenic effect of fluconazole (4). Cumulative experience in the detection of antiplatelet antibody in 234 patients with idiopathic thrombocytopenic purpura, systemic lupus erythematosus and other clinical disorders. Lecart C, Claerhout F, Franck R, Godts P, Lilien C, Macours L, Schuerwegh, Longree H, Mine M, Strebelle P, Van Gijsegem M, Wesel S. The risks of complications from malarial infection occurring during pregnancy are increased, especially in women not living in endemic areas. Based on the overall results, the investigators concluded that a full reproductive study was warranted (3). The no-observable-effect doses for embryotoxicity in rats and rabbits were about 0. Neonatal convulsions were observed in two male infants after in utero exposure to clomipramine (maternal doses not specified) (6). A 1998 review concluded that colchicine by itself may not have a significant direct adverse effect on sperm production or function (36). Because of the potential for serious adverse effects in nursing infants, women receiving this drug should not breastfeed. A 37-year-old woman undergoing an urgent cesarean section with general anesthesia (succinylcholine, thiopental, nitric oxide, oxygen, and isoflurane) developed tachycardia, respiratory acidosis, and hyperthermia (12). In a 2009 report from the Multicenter Study of Hydroxyurea in Sickle Cell Anemia, attempts were made to prevent pregnancies during the randomized double-blind placebo-controlled trial (25). In neither of the cited studies were adverse effects noted in the mothers or fetuses. In a study involving pregnant rats, buprenorphine was administered by a continuous infusion in doses of 0. This method results in plasma concentrations 100 times less than those achieved with oral administration (1). A urogenital sinus was identified in the aborted fetus but the external genitalia were normal except for a single opening in the vulva. The molecular weight (about 435), long elimination half-life (41 ± 20 hours), and lipid solubility suggest that the drug will be excreted into breast milk. In dogs, hypospermatogenesis and atrophy of the prostate and epididymides was observed at a dose that was 0. Because of the similarity of the cases, the authors thought it might be a new syndrome, which they termed cerebroarthrodigital syndrome, in which the primary pathogenetic event is a neural tube-neural crest dysplasia (14). Anaesthetic considerations in a parturient with critical coronary artery disease and a drug-eluting stent presenting for caesarean section. However, human immunoglobulin (IgG) does cross and, therefore, cetuximab may also cross (1). Pregnancy outcomes in women with familial, Mediterranean fever receiving colchicine: is amniocentesis justified? A 23-year-old woman with primary lipoprotein lipase deficiency was managed with a low-fat diet throughout gestation (9).

Angiofollicular lymph hyperplasia

Neither the carcinogenic potential nor the mutagenic potential has been evaluated. Therefore, it is doubtful if clinically significant amounts will be excreted into milk. Although not specifically listing cefepime, the American Academy of Pediatrics classifies other cephalosporin antibiotics as compatible with breastfeeding (for example, see Cefadroxil and Cefazolin). A population-based case­control study of vaginal econazole in pregnancy was conducted using the Hungarian Case­Control Surveillance of Congenital Abnormalities (10). Confusion has arisen over the actual identity of commercial products (see above) and without chemical analysis, the actual herb ingested is uncertain. Long-term studies of growth and mental development in offspring exposed to chlorambucil during the 2nd trimester, the period of neuroblast multiplication, have not been conducted (15). Six pregnancy losses were recorded, four described earlier (6) and two new cases of fetal deaths at 18 and 26 weeks, both in women with lupus anticoagulant and previous fetal loss. She had taken the tablets periodically over the past 9 years and throughout her pregnancy. The available dose of hydralazine in 75 mL of milk was estimated to be 13 mcg (5). A 2008 study conducted by the manufacturer described the use of duloxetine 40 mg every 12 hours for 3. Clinical and laboratory studies on cefoxitin in the field of obstetrics and gynecology. If exposure does occur during pregnancy, the risk for developmental toxicity appears to be low, but long-term studies of exposed offspring for functional abnormalities and other developmental toxicity are warranted. Both normal and malformed newborns have been reported following the use of cyclophosphamide in pregnancy (1­33). A study published in 1998 described 12 mothers who breastfed their infants while taking haloperidol, chlorpromazine, or trifluoperazine for bipolar depression (3 cases), manic disorder (1 case), schizo-affective disorder (5 cases), or schizophrenia (3 cases) (23). The strongest evidence for an association between folic acid and fetal defects comes from cases treated with drugs that either are folic acid antagonists or induce folic acid deficiency, although agreement with the latter is not universal (70,74,75). No evidence of impaired fertility or fetal harm was observed in reproduction studies in rats and rabbits at doses up to 10 times the daily human dose (1). Developmental toxicity was observed in two animal species at doses close to the human dose. At the highest dose, abortions and severe external or soft-tissue malformations were observed. A 1994 report described a woman with primary thrombocythemia who had lost two previous pregnancies from stillbirths (15). Using a perfused human placenta, one investigation discovered that the percentage of hydrocortisone converted to cortisone in three different perfusion mediums was 73% (buffer), 85% (1% human serum albumin), and 78% (washed calf red blood cells) (18). The drug is teratogenic in mice and rats, but not in rabbits, at high doses (1­5). Necrotizing enterocolitis was reported in an infant exposed throughout pregnancy and during breastfeeding to escitalopram 20 mg/day (15). Position Statement of a Joint Committee of the American College of Obstetricians and Gynecologists and the American College of Allergy, Asthma and Immunology. Although the exact mechanism of cocaine-induced abruptio placentae is still unknown, the pharmacologic effects of the drug offer a reasonable explanation. Low-molecular-weight heparin for obstetric thromboprophylaxis: experience of sixty-nine pregnancies in sixty-one women at high risk. The relatively low molecular weight (about 201 for the free base) suggests that dexmedetomidine will cross the human placenta, but the plasma protein binding and short terminal elimination half-life might limit the exposure of the embryo and/or fetus, at least early in gestation. The Collaborative Perinatal Project monitored 50,282 mother­child pairs, 168 of whom had 1st trimester exposure to topical camphor (7, pp. Matched controls were obtained from pregnant women who had infants without defects. The cetirizine group had a significantly lower rate of nausea and vomiting (7% vs. Bosutinib is indicated for the treatment of adult patients with chronic, accelerated, or blast phase Philadelphia chromosomepositive chronic myelogenous leukemia with resistance or intolerance of prior therapy. Peak serum levels in the fetuses were 1000-fold lower than levels measured in the dams, but the agent still induced bone marrow and spleen myelopoiesis in the fetus and neonate (2). No desmopressin-related adverse effects were observed in the eight newborns (two sets of twins).
