Mean concentrations of levodopa (expressed as ng/mg protein) in the maternal serum weight loss pills no caffeine orlistat 120 mg free shipping, placental tissue (including umbilical cord), fetal peripheral organs (heart, kidney, muscle), and fetal neural tissue (brain and spinal cord) were 8. The levels in the placentas and fetuses for both levodopa and dopamine were much higher than those measured in control tissue. Moreover, the relatively high concentrations of dopamine in fetal peripheral organs and neural tissue implied that the fetuses had metabolized levodopa. The investigators cautioned that, because neurotransmitters were known to alter early neural development in animals and in cultured cells, the increased amounts of dopamine found in their study suggested that chronic use of levodopa during gestation could induce long-term damage (7). The pregnancy outcomes of two women who were treated with levodopa or carbidopa/levodopa during three pregnancies were described in a 1985 paper (8). The first woman, with at least a 7-year history of parkinsonism, conceived while being treated with carbidopa/levodopa (five 25/250-mg tablets/day) and amantadine (100 mg twice daily). Two years later, while still undergoing treatment with levodopa, she delivered a term, female, 2951-g infant. A 1987 retrospective report described the use of carbidopa/levodopa, starting before conception, in five women during seven pregnancies, one of which was electively terminated during the 1st trimester (9). Maternal complications in three pregnancies included slight 1st trimester vaginal bleeding, nausea, and vomiting during the 8th and 9th months (the only patient who reported nausea and vomiting after the 1st trimester) and depression that resolved postpartum, and preeclampsia. One infant, whose mother took amantadine and carbidopa/levodopa and whose pregnancy was complicated by preeclampsia, had an inguinal hernia. No adverse effects or congenital anomalies were noted in the other five newborns and all remained healthy at follow-up (approximately 1­5 years of age). She conceived 5 months after treatment began and eventually delivered a healthy, 3540-g male infant at term. The male infant weighed 2350 g at birth and was developing normally at the time of the report. Two previous pregnancies had occurred while the woman was being treated with daily doses of levodopa 100 mg and carbidopa 10 mg. Spontaneous abortions had occurred in both pregnancies; one at 6 weeks and the other at 12 weeks. A successful pregnancy in a 27-year-old woman with Segawa disease was reported in 2009 (12). In one of those patients, her first two pregnancies were treated with carbidopa/levodopa and both ended in abortions (see reference 11 above). The ninth pregnancy was not treated with any agent and the severely asphyxiated newborn died after birth (12).

Milk samples were collected from both women during the first 4 days after dosing weight loss pills in pakistan generic orlistat 120 mg online, and from one woman at various intervals up to 56 days. The investigators estimated that a 4-kg infant consuming 1000 mL of milk daily would ingest 0. Although these amounts are not thought to be harmful to the nursing infant, they are insufficient to provide adequate protection against malaria (3). Because the antimalarial agent has a long plasma half-life, averaging nearly 12 days during pregnancy (2) and 14. Moreover, higher milk concentrations of mefloquine than those reported should be expected after therapeutic or weekly prophylactic doses (18). Mefloquine antimalarial prophylaxis in pregnancy: dose finding and pharmacokinetic study. A review of its antimalarial activity, pharmacokinetic properties and therapeutic efficacy. Moreover, there have been no long-term studies of the safety of melatonin in nonpregnant humans. Thus, the use in human pregnancy has most likely occurred but apparently has not been reported. Moreover, melatonin doses very near the human dose (again based on body weight) did adversely affect the development of the neuroendocrine reproductive axis in female rat fetuses, a toxicity that would not be immediately apparent. There is probably no relationship of this toxicity in pregnant humans consuming occasional low (10 mg) doses, but high doses or frequent use during gestation should be avoided. In addition, maternal consumption of melatonin may affect the fetal suprachiasmatic nucleus with resulting adverse effects for the prenatal and postnatal expression and entrainment of circadian rhythms (2). Animal-derived products should be avoided because of the risk of contamination and/or the transmission of infectious agents. Secretion of melatonin from the pineal body occurs in a diurnal pattern (during periods of darkness) and affects sleep pattern (3­5). These include increased concentrations of serotonin and aminobutyric acid in the brain; enhanced activity of an enzyme (pyridoxal-kinase) that is involved in the synthesis of serotonin, aminobutyric acid, and dopamine; inhibition of gonadal development; and a role in the control of estrus (5). Melatonin is commercially available as a nutritional supplement, either as a synthetic or animal-derived product (6). Two sources recommend avoiding the product produced from animal pineal tissue (beef cattle) because of the theoretical risk of contamination or viral transmission (1,6). A 1981 study evaluated the effect on female offspring of maternal administration of melatonin to rats (7). Female offspring of melatonin-treated rats showed significantly later vaginal opening compared with the control groups. The investigators concluded that the exogenous melatonin crossed the placenta and demonstrated an inhibitory influence on the development of the neuroendocrine reproductive axis in the fetus (7). A 2000 study suggested that melatonin might be useful in protecting the fetal brain from neurodegenerative conditions, such as fetal hypoxia and preeclampsia (10). These conditions may involve free radical production, and melatonin is known to be scavenger of oxygen free radicals.

Postmarketing surveillance of lovastatin and simvastatin exposure during pregnancy weight loss urination orlistat 60 mg order fast delivery. The predominant role of maternal toxicity in lovastatininduced developmental toxicity (abstract). Central nervous system and limb anomalies in case reports of first-trimester statin exposure. Gestational exposure to lovastatin followed by cardiac malformation misclassified as holoprosencephaly. Because of the very 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 (1). Because loxapine is indicated for severe debilitating mental disease, the benefits to the mother appear to outweigh the unknown risk. A 1996 review on the management of psychiatric illness concluded that patients with histories of chronic psychosis represent a highrisk group (for both the mother and the fetus) and should be maintained on pharmacologic therapy before and during pregnancy (2). Moreover, neonates exposed to antipsychotic drugs in the 3rd trimester are at risk of extrapyramidal and/or withdrawal symptoms (4). The manufacturer did not state the amount of plasma protein binding or the elimination half-life, but did state that loxapine was rapidly removed from the plasma and distributed in tissues (4). Loxapine belongs to the antipsychotic subclass of dibenzapine derivatives that includes asenapine, clozapine, olanzapine, and quetiapine. In reproductive studies with rats, rabbits, and dogs, no embryotoxicity or teratogenicity was observed. However, with the exception of one rabbit study, the dose used was 2 times the maximum recommended human dose (presumably based on weight) (4,5). Renal papillary abnormalities were found in offspring of rats treated from mid-gestation with doses approximately equivalent to the usual human dose (4). The molecular weight (about 328 for the free base) suggests that it will cross to the embryo­fetus. A 2009 review cited information received from the manufacturer regarding the outcomes of three pregnancies exposed to loxapine (6). The retrospective outcomes were one baby with achondroplasia; one with multiple unspecified anomalies; and one infant, exposed throughout pregnancy, with tremors at 15 weeks of age (6). However, achondroplasia is a known autosomal dominant inheritance defect and is not related to drug exposure. The relatively low molecular weight of loxapine (about 328 for the free base) suggests that the drug will be excreted into breast milk. Because of the very limited human experience with atypical antipsychotics, the American College of Obstetricians and Gynecologists does not recommend the routine use of these agents during lactation, but a risk­benefit assessment may indicate that such use is appropriate (1). In a third species, the drug caused fetal loss, but the cause of the loss is unknown because systemic absorption of lubiprostone, at least in humans, is minimal, although one metabolite is absorbed systemically. Lubiprostone is indicated for the treatment of chronic idiopathic constipation in adults. It has low systemic bioavailability with plasma concentrations below the level of quantitation (10 pg/mL).

Because placental trophoblasts also express many of these same cytokines weight loss pills or shakes purchase generic orlistat, an in vitro study was conducted to determine if imiquimod exposure during pregnancy could alter normal placental function. The results suggested that imiquimod would not induce the expression of inflammatory cytokines in placenta trophoblasts (2). The fetal effects included increased resorptions, decreased body weight, delays in skeletal ossification, and bent limb bones. When these doses were continued throughout pregnancy, parturition, and lactation, no effects were observed on growth or postnatal development. However, bent limb bones in the fetuses were noted, as they were with exposure during organogenesis, in the absence of maternal toxicity. Multiple tests with imiquimod revealed no evidence of mutagenic or clastogenic potential (1). The low molecular weight (about 240) and long elimination half-life after systemic absorption (about 20 hours) suggest that the drug will reach the embryo and/or fetus. However, because the systemic concentrations are very low, the actual exposure appears to be clinically insignificant. Because there was very good clinical response, she was prescribed additional treatment, but the woman was lost to follow-up until she delivered vaginally at 41 weeks. A 2006 report described the outcomes of seven pregnancies exposed to topical imiquimod, all ending in live births with a mean birth weight of 3528 g (4). The drug had been used for genital warts in four cases and for warts of the hand, face, or foot in three. Doses of the 5% cream ranged from once daily to four times per week with durations ranging from 1 to 10 weeks (average 5 weeks). Two women used the drug in the 1st trimester, one in the 2nd trimester, two in the 2nd and 3rd trimesters, and two in the 3rd trimester only (4). Two studies reported the use of imiquimod for the treatment of anogenital warts in a total of 21 pregnant women (5,6). The relatively low molecular weight (about 240) and long elimination half-life (about 20 hours) suggest that the drug will be excreted into breast milk. However, the amount absorbed systemically and available for excretion into milk is very low and probably is clinically insignificant. Therefore, although the risk to a nursing infant is unknown, use of imiquimod by the mother appears to be compatible with breastfeeding.

The study population consisted of 563 male infants with hypospadias and 1444 male infants with no major birth defects best weight loss pills lipo 6 order orlistat. During 48 hours, the mean amounts of loratadine and metabolite recovered from the milk were 4. Based on this estimate, and the fact that the dose used in the study was four times the current recommended dose, there is probably little clinical risk to a nursing infant whose mother was taking 10 mg of loratadine per day. The American Academy of Pediatrics classifies loratadine as compatible with breastfeeding (11). Effects of perinatal loratadine exposure on male rat reproductive organ development. Fetal safety of loratadine use in the first trimester of pregnancy: a multicenter study. Evaluation of an association between loratadine and hypospadias-United States, 1997­2001. The long-term effects of in utero exposure on neurobehavior, especially when the exposure occurs in the latter half of pregnancy, have not been studied but are of concern. Occasional, non-dose-related malformations (reduction of tarsals, tibia, metatarsals, malrotated limbs, gastroschisis, malformed skull, and microphthalmia) were observed in rabbits, but these defects have also randomly occurred in controls. Lorazepam crosses the placenta, achieving cord levels similar to maternal serum concentrations (2­5). The hypotonia, attributed to lorazepam because of the absence of such reports in pregnancies exposed to clozapine alone, resolved 5 days after birth. An abstract published in 1999 found an association between lorazepam and anal atresia (7). Using data from a French pregnancy registry, the investigators reported that among infants exposed to benzodiazepines 5 of 6 cases of anal atresia were exposed to lorazepam (p = 0. Lorazepam has been used in labor to potentiate the effects of narcotic analgesics (8). Although not statistically significant, a higher incidence of respiratory depression occurred in the exposed newborn infants. In one study, no effects on the nursing infant were reported (9), but the slight delay in establishing feeding was a cause for concern (11). In another study, 5 mg of oral lorazepam was given 1 hour before labor induction and the effects on feeding behavior were measured in the newborn infants (12). During the first 48 hours, no significant effect was observed on volume of milk consumed or duration of feeding. The effects of exposure to benzodiazepines during breastfeeding were reported in a 2012 study (13). The investigators concluded that their results supported the recommendation that the use benzodiazepines was not a reason to avoid breastfeeding (13).

One of the metabolites is active weight loss pills kidney transplant orlistat 120 mg order line, but the concentration is low and is not thought to contribute significantly to clinical activity. When this dose was continued in pregnancy and during lactation, reduced peripartum and postnatal survival, reductions in body weight gain, and delayed physical development (eye opening and vaginal patency) were observed. Solifenacin was not carcinogenic in mice and assays for mutagenicity were negative. The molecular weight (about 363 for the free base) and prolonged plasma elimination half-life suggest that the drug and/or its metabolites will cross to the embryo­fetus. The molecular weight (about 363 for the free base) and prolonged plasma elimination half-life suggest that the drug and/or its metabolites will be excreted into breast milk. Although neonates are particularly sensitive to anticholinergics, two other agents in the anticholinergic class are classified by the American Academy of Pediatrics as compatible with breastfeeding (see Atropine and Scopolamine). The effect of solifenacin exposure in a nursing infant is unknown, but the risk of toxicity probably is low. It should be noted, though, that sorafenib inhibits angiogenesis, a critical component of embryonic and fetal development. The manufacturer recommends that adequate contraception should be used during therapy and for at 2 weeks after completing therapy (1). However, renal cell carcinoma can be fatal, so if a woman requires sorafenib and informed consent is obtained, treatment should not be withheld because of pregnancy. Sorafenib is indicated for the treatment of patients with advanced renal cell carcinoma. After hepatic metabolism, at least eight metabolites have been identified, one of which has activity similar to the parent compound. The drug was clastogenic, in the presence of metabolic activation, in one test but was not mutagenic or clastogenic in other tests. An intermediate in the manufacturing process that also is present in the final product (<0. Specific studies for fertility impairment have not been conducted, but sorafenib does adversely affect male and female reproductive organs. These effects, more pronounced in rats than in mice or dogs, included testicular atrophy and degeneration, oligospermia, degeneration of epididymis, prostate, and seminal vesicles, central necrosis of the corpora lutea, and arrested follicular development at doses that were about 0. The molecular weight (433 for the free acid) and the long elimination half-life suggest that the drug will cross to the embryo and/or fetus. The molecular weight (433 for the free acid) and the long elimination half-life suggest that the drug will be excreted into breast milk. The effects of this exposure on a nursing infant are unknown, but severe toxicity may occur. In adults, hand­foot skin reaction and rash were the most common adverse events, but diarrhea, hemorrhage, and hypertension were also common.

The pharmacokinetics of paclitaxel are markedly affected by the dose and infusion rate with elimination half-lives varying from approximately 13 to 53 hours weight loss pills for 13 year olds buy 120 mg orlistat with mastercard. The free commercial form of paclitaxel contains the vehicle polyoxyethylated castor oil (also known as polyoxyl 35 castor oil) (1,2). The drug was not mutagenic in one test but was clastogenic in vitro (human lymphocytes) and in vivo (micronucleus test in mice). Interestingly, a 1995 research report concluded that some, paclitaxelinduced, embryotoxicity in animals might be due to the polyoxyethylated castor oil vehicle (2). In an experiment with chick embryos, the researchers compared free paclitaxel containing the vehicle with liposome-encapsulated paclitaxel. A 20-fold higher dose was required to produce the same degree of toxicity with the liposome-encapsulated product (2). In a follow-up to the above study, the same group of researchers compared the developmental toxicity in rats of free and encapsulated paclitaxel (3). At 10 mg/kg, toxicity and malformations were noted that were similar to those observed with the free drug at 2 mg/kg. Thus, encapsulation appeared to increase the dose needed to produce toxicity and malformations (3). However, encapsulation of paclitaxel could markedly increase or decrease the amount of drug crossing the placenta to the fetus. The authors of the study cited examples in perfused in vitro human placentas in which liposome encapsulation reduced placental transfer. In contrast, they also cited studies in intact rats and rabbits that have shown that encapsulation enhanced placental transfer, possibly by a process involving placental intracellular sequestration and degradation of liposomes (3). Although the molecular weight (about 854) suggests that paclitaxel will cross the placenta, the extensive protein binding might limit the exposure of the embryo or fetus. Of interest, in an in vitro model, paclitaxel slowly crossed the human placenta to the fetal side (4). In a novel case report, a 21-year-old woman was diagnosed with metastatic ovarian cancer that was initially treated with surgery that left her uterus, right fallopian tube, and ovary in situ (5). Subsequent high-dose chemotherapy was then given (paclitaxel, carboplatin, and/or cyclophosphamide). After her chemotherapy, the woman received a successful transplant of autologous peripheral blood stem cells. Approximately 16 months after the transplant, she conceived but had a 1st trimester miscarriage. She conceived again several months later and eventually delivered a healthy full-term 3000-g female infant. Six days after debulking surgery that preserved the pregnancy, she received the first cycle of paclitaxel (135 mg/m2) over 24 hours and cisplatin (75 mg/m2) over 4 hours.

The cases of postaxial polydactyly weight loss agents orlistat 60 mg sale, cleft lip, and hypospadias are relatively common birth defects. Only postaxial polydactyly has been associated with inborn errors of cholesterol metabolism. The trisomy and chromosomal abnormality were also dismissed as drug induced because there is no evidence that these defects could be caused by drugs. There were 13 cases of congenital defects in retrospective reports; 6 involving simvastatin and 7 with lovastatin (7). There were no specific patterns observed in the prospective or retrospective reports (7). Among 19 cases followed by a teratology information service in England, seven involved 1st trimester exposure to simvastatin (8). A 2005 case report described the pregnancy outcome of a 33-year-old woman treated with simvastatin in the first 8 weeks of an unplanned pregnancy (9). Diseases in the patient included hypercholesterolemia, hypertension, morbid obesity, and type 2 diabetes mellitus. Other drugs used by the woman were glimepiride, orlistat, ramipril, thiocolchicoside (a muscle relaxant), metformin, ciprofloxacin, and aspirin. When pregnancy was diagnosed at 8 weeks, all medications were stopped, and she was started on methyldopa and insulin. However, the passage of simvastatin into milk should be expected because at least two other similar agents (fluvastatin and pravastatin) appear in human milk. Simvastatin (mk-0733): oral teratogenicity study in rats pre- and postnatal observation. Pregnancy outcome following exposure to orlistat, ramipril, glimepiride in a woman with metabolic syndrome. The animal reproduction data suggest a potential for toxicity, but not for teratogenicity. The in vitro study described suggests that sirolimus could affect growth of the fetal and neonatal heart. Although the clinical significance of the concentrations used in that study is unknown, there was no attempt to determine the no-effect concentration. The very limited human pregnancy experience prevents a full assessment of the risk. Reviews discussing transplantation in pregnancy are ambivalent regarding the use of sirolimus; with some not recommending its use (1) and others implying that it may be continued in pregnancy (2). Until human data are available, however, the safest course is to avoid the drug in pregnancy.

Reversible impotence weight loss pills you can buy under 18 buy orlistat 60 mg online, however, has been described in men treated with nizatidine for therapeutic indications (7). A genetic counselor was consulted about a woman who had taken nizatidine during the 14th through the 16th postconception weeks (T. A 1996 prospective cohort study compared the pregnancy outcomes of 178 women who were exposed during pregnancy to H2 blockers with 178 controls matched for maternal age, smoking, and heavy alcohol consumption (8). All of the women had contacted a teratology information service concerning gestational exposure to H2 blockers (subjects) or nonteratogenic or nonfetotoxic agents (controls). The investigators concluded that 1st trimester exposure to H2 blockers did not represent a major teratogenic risk (8). Nizatidine was the only acid- suppressing drug exposure in three infants, none of whom had birth defects (see Omeprazole for additional details of this study) (9). A population-based, observational cohort study formed by linking data from three Swedish national healthcare registers over a 10-year period (1995­2004) was reported in 2009 (10). The authors proposed three possible mechanisms for their findings: (a) exposure to increased amounts of allergens could cause sensitization to digestion labile antigens in the fetus; (b) the maternal Th2 cytokine pattern could promote an allergy-prone phenotype in the fetus; and (c) maternal allergen-specific immunoglobulin E could cross the placenta and sensitize fetal immune cells to food- and airborne allergens. A 2005 study evaluated the outcomes of 553 pregnancies after exposure to H2 blockers, 501 (91%) in the 1st trimester (11). The agents and number of cases were nizatidine 15, cimetidine 113, famotidine 75, ranitidine 335, and roxatidine 15. A 2009 meta-analysis of published studies was conducted to assess the safety of H2 blockers that were used in 2398 pregnancies (12). Nizatidine was not recommended because of the adverse animal reproduction data (16). Nevertheless, the very limited human pregnancy data suggest that other agents in this class are preferred. A 2010 study from Israel identified 1148 infants exposed in the 1st trimester to H2 blockers (18). Three women, who had been breastfeeding for 3­8 months, were administered nizatidine (150 mg) as a single dose and as multiple doses given every 12 hours for five doses. Serum and milk samples from both breasts were collected at intervals 12 hours after a dose. The mean total amount of drug measured in the milk from both breasts during a 12-hour interval was 96. Peak concentrations of the drug in milk occurred between 1 and 2 hours after a dose (19).

Of the 477 reports weight loss pills hollywood 60 mg orlistat order, all involving 1st trimester exposure, 386 were prospective (319 simvastatin, 67 lovastatin) and 91 were retrospective (53 simvastatin, 38 lovastatin). If sirolimus is used in pregnancy, or in the event of inadvertent exposure, close monitoring of the embryo­fetus for developmental toxicity is warranted. The manufacturer recommends that women of childbearing potential use effective contraception before and during therapy, and for 12 weeks after therapy is stopped (3). It is recommended that it initially be used in combination with cyclosporine and corticosteroids. Chemically, the drug is a macrocyclic lactone produced by Streptomyces hygroscopicus. It is highly protein bound to plasma albumin and other proteins (about 92%) and has a mean terminal half-life in renal transplant patients of about 62 hours (3). When combined with cyclosporine, increased embryo­fetal death compared with sirolimus alone was observed in rats. In pregnant rabbits, there were no effects on development at a maternal toxic dose about 0. Cardiac myocytes were isolated from 15-day-old fetal rats and exposed for 5 days in culture medium to various concentrations of sirolimus. The exposed cells were then washed and grown in culture medium without sirolimus for an additional 5 days. Sirolimus inhibited both short-term and subsequent proliferation of cardiac myocytes. The investigators noted that fetal and neonatal heart growth occurs predominantly through myocyte proliferation (5). The molecular weight (about 914) is within the range for passive diffusion, and the elimination half-life will allow the drug to be present at the maternal:fetal interface for a long interval. However, the high protein binding should limit the amount of drug available to cross the placenta. A 2003 report from the National Transplantation Pregnancy Registry briefly described four female kidney recipients who were treated during pregnancy with sirolimus and other immunosuppressants (6). Immunosuppression during the first 24 weeks consisted of mycophenolate mofetil, tacrolimus, and prednisone (6). A 2004 case report described the use of sirolimus in a 21-year-old woman who became pregnant 3 years after liver transplantation (7). At the time of conception, immunosuppression was maintained with sirolimus, tacrolimus, and corticosteroids (doses not specified). The molecular weight (about 914) and the prolonged half-life (about 62 hours) suggest that the drug will be excreted into breast milk. The effect of this potential exposure on a nursing infant is unknown, but consideration should be given to the carcinogenic properties of sirolimus, especially with long-term exposures. A 2002 review concluded that because of possible drug transfer into milk, women taking sirolimus should not breastfeed (1).

Rozhov, 42 years: In patients with cancer, the plasma elimination half-life was 250 ± 285 hours (about 10 ± 12 days), but in healthy volunteers, the half-life was 415 ± 104 hours (about 17 ± 4. Effect of phentolamine methanesulfonate upon uterine contractility induced by l-norepinephrine in pregnancy. Two weeks later, sildenafil was discontinued because of its high cost and the dose of diltiazem was increased to 180 mg/day. In adults, increased incidences of several adverse effects have been observed, including dizziness and somnolence, blurred vision, peripheral edema, myopathy, and decreased platelet count.

Vasco, 34 years: However, a 1991 reference described an infant and a fetus with limb reduction deformities after 1st trimester exposure to isotretinoin (38). A portion of this report also described 67 newborns that were treated for jejunal atresia, 20 of whom were one of a set of twins. Because these intermediate arene oxide metabolites have been associated with teratogenicity (see Carbamazepine, Phenytoin, and Valproic Acid), this may indicate a lower risk of teratogenicity with oxcarbazepine compared with the other agents. Other drugs taken by the women included aspirin, nonsteroidal anti-inflammatory agents, prednisone (<10 mg/day), and hydroxychloroquine.

Bandaro, 21 years: Maternal antihypertensive therapy with beta-blockers associated with poor outcome in very-low birthweight infants.

Orknarok, 30 years: Methadone concentrations in breast milk are reported to be sufficient to prevent withdrawal in addicted infants (see Breastfeeding Summary below). In comparison with controls, the adjusted (for maternal age, birth order, gestational age, and smoking, but not for alcohol abuse) relative risks for the three outcomes were congenital malformations 1. In near-term macaques, the steady-state fetal:maternal plasma ratio was approximately 0. In a 2004 case report, a 30-year-old woman was taking naltrexone (50 mg/day) for opiate addiction while breastfeeding her 1.

Bengerd, 45 years: In a controlled study, 110 patients received one to three antibiotics during the 1st trimester for a total of 589 weeks (16). Although avoiding the use of paroxetine in pregnancy, especially high doses, may be an option, the apparently low risk of embryo­fetal harm must be balanced against the risk of untreated or undertreated depression. There were eight neonatal complications (three cardiovascular, four respiratory, one hypotonia; complications were not further described), and four infants were admitted to the neonatal intensive care unit (reasons not provided) (6). The highest dose resulted in stillborns and lower pup viability, but all doses lowered pup body weight at birth, which persisted to adulthood.

Kalan, 62 years: The toxicity was manifested as early and total resorptions, postimplantation loss, and a decrease in the total number of live fetuses (1). However, its use in such cases may be of benefit in women who will not consider therapeutic abortion. Metoclopramide effect on faltering milk production by mothers of premature infants. Intraoperative amniocentesis and indomethacin treatment in the management of an immature pregnancy with completely dilated cervix.

Denpok, 41 years: The molecular weight of the free base (about 297), the moderate protein binding and metabolism, and the extended plasma half-life suggest that the drug will be excreted into breast milk. The results and conclusions of the four studies were similar to those described above. Prednisone has been used successfully to prevent neonatal respiratory distress syndrome when premature delivery occurs between 28 and 36 weeks of gestation (22). Because of ion trapping of the drug in the more acidic (as compared with plasma) milk, accumulation occurs with milk:plasma ratios of 1.

Arokkh, 32 years: Successful fetal outcome after exposure to idarubicin and cytosine-arabinoside during the second trimester of pregnancy-a case report. Neither have studies been conducted for carcinogenicity, mutagenicity, or effects on fertility. If used near delivery, the newborn infant should be closely observed for 24­48 hours for signs and symptoms of blockade. A 1991 population-based case­control study conducted in Sweden found an association between childhood leukemia and nitrous oxide anesthesia during delivery (102).

Kliff, 50 years: A group of 568 women was randomly assigned to receive either 15 mmol of magnesium-aspartate hydrochloride (N = 278) or 13. A decrease in intracranial volume has been reported after 1st trimester exposure to methyldopa (6,7). However, the substances probably are compatible with breastfeeding because only minimal amounts are absorbed. Several studies for mutagenic or clastogenic effects with lisdexamfetamine were negative.

Javier, 33 years: A 2002 prospective study compared two groups exposed to antidepressants throughout gestation, either to tricyclics (N = 46 including 3 to nortriptyline) or to fluoxetine (N = 40), with 36 nonexposed, not depressed controls (6). Many of these agents are found in food, such as daidzein and genistein from soybeans (1,2). The Collaborative Perinatal Project monitored 50,282 mother­child pairs, 3546 of whom had 1st trimester exposure to penicillin derivatives (1, pp. At 5 and 12 hours after the dose, isoniazid levels in the milk were twice the levels in simultaneously obtained plasma.

Rocko, 59 years: In rats and rabbits, placental transfer of saquinavir is low (<5% of maternal plasma concentrations) (1). The molecular weight (about 535 for the hydrochloride salt forms) is low enough that transfer to the fetus should be expected. A 1995 reference described the placental transfer of levodopa and the possible fetal metabolism of the drug to dopamine, its active metabolite (7). Tanigawa K, Kawaguchi M, Tanaka O, Kato Y Skeletal malformations in rat offspring.

Yespas, 47 years: Although hypoglycemia in humans has not been shown to be teratogenic (23,24), at least one author has concluded that this has not been adequately studied (25). Genetic studies on the anomalous twin could not be conducted because of delay in receiving permission to study it. Of the remaining 135 pregnancies, there were 56 spontaneous abortions or fetal deaths (none late) (1 malformed fetus), and 79 elective abortions (4 malformed fetuses) (2). The Collaborative Perinatal Project recorded seven 1st trimester exposures to nitroglycerin and amyl nitrite plus eight other patients exposed to other vasodilators (7).

Abe, 64 years: The serum half-life of lithium in newborns is prolonged, averaging 68­96 hours, as compared with the adult value of 10­20 hours (7,21). Animal reproduction studies and studies for carcinogenicity, mutagenicity, and fertility have not been conducted (1). Each of the exposures involved unsuccessful attempts by the women to induce abortion. The usual dose consumed was 800 mcg (two 200-mcg tablets orally plus two tablets vaginally), but some women may have taken as much as 9200 mcg (46 tablets) (8).

Copper, 48 years: The molecular weight of nepafenac (about 254) is low enough for excretion into breast milk. Neuroblastoma and fetal exposure to phenytoin in a child without dysmorphic features. Phenytoin-induced thrombocytopenia has also been reported as a mechanism for hemorrhage in the newborn (76). The most common (5%) adverse reaction in adults receiving monotherapy was nasopharyngitis (3).

Hengley, 36 years: Four patients undergoing therapeutic abortion were given a single 15-mg 35S-labeled oral dose 2 hours before pregnancy termination (41). No evidence of teratogenicity was observed in pregnant rats and rabbits exposed to maximum plasma concentrations up to 399 and 183 times, respectively, of those produced by a human dose of 1 mg/kg/day. Excretion of tryptophan metabolites as affected by pregnancy, contraceptive steroids, and steroid hormones. In nine prospectively enrolled pregnancies exposed in the 1st trimester to primidone and lamotrigine, with or without other anticonvulsants, the outcomes were seven live births without birth defects, one elective abortion, and one birth defect (21).
