Medication Considerations in Pregnancy
• Need to weigh risks and benefits carefully with
both maternal and fetal well-being in mind
• Involve patient in the decision-making process
incorporating their goals, values, concerns and
• Avoid use of medications if possible, especially in
• If benefits outweigh risks, use lowest effective
• Information about safety constantly changing,
When Making Decisions about Medications
– Severity of the disorder, current symptoms – Past psychiatric history – Patient attitude toward and past experience with
– Risk of fetal exposure to medications – Risk of untreated psychiatric il ness to the mother – Risk of relapse associated with discontinuation of
SSRI’s in Pregnancy
• All FDA Pregnancy class C except for
• However, generally considered safe as a class
• Large case-control study showed any 1st TM
SSRI use not associated with increased risk of birth defects – Louik et al, 2007
• Cohort study of 462 Norwegian women taking
SSRI’s in 1st TM did not show any increase in birth defects – Nordeng et al, 2012 Specific SSRIs in Pregnancy
• Paroxetine (Class D)
– 1986-2006 meta-analysis showing 1st trimester paroxetine
exposure associated with increased risk cardiac defect
(odds ratio 1.72; 95% CI, 1.22-2.42) – Bar-Oz et al, 2007.
– 1997-2006 Case-control study, Netherlands, significant
increase in atrial septal defect for women using Paroxetine
first trimester (AOR, 5.7; 95% CI, 1.4–23.7) – Bakker et al,
– 2007Case-control study showed dose-response
relationship, women exposed to >25mg/day of paroxetine
in the 1st TM had increased risk of infant with any major
congenital malformation (OR 2.23; 95% CI 1.19-4.17) or
major cardiac malformation (OR 3.07; 95% CI 1.00 – 9.42) –
– 2007 Case-control study with increased ventricular outflow
tract obstruction defects (odds ratio, 3.3; 95% CI, 1.3 to
Specific SSRIs in Pregnancy
• Sertraline (Class C)
– 2007 Case-Control study, 1st TM sertraline associated
with omphalocele (odds ratio, 5.7; 95% CI, 1.6 to 20.7)
and septal defects (odds ratio, 2.0; 95% CI, 1.2 to 4.0)
• Fluoxetine (Class C)
– Longest used and most studied – No increased risk of spontaneous pregnancy loss or
– Taking fluoxetine in the third trimester associated with
increased risk of premature delivery, low birth weight,
admission to special care nursery and poor neonatal
adaptation including respiratory difficulty, cyanosis on
feeding, and jitteriness – Chambers et al, 1996 SSRIs – withdrawal syndrome
• The SSRI neonatal withdrawal syndrome is
characterized by characterized by convulsions, irritability, abnormal crying, and tremor.
• 2005 Study: 93 reported cases, 64 of the cases
were associated with paroxetine (Paxil), 14 with fluoxetine (Prozac), 9 with sertraline (Zoloft), and 7 with citalopram (Celexa) – Sanz et al, 2005
• In most cases, these symptoms are mild and
disappear by two weeks of age with no treatment or with only supportive care.
SSRIs and Persistent Pulmonary Hypertension (PPHN)
• PPHN = failure to transition adequately from fetal to
neonatal circulation at birth causing hypoxia and
• Scandinavian Cohort Study 1996 and 2007
– Exposure to SSRIs in late pregnancy associated with an
increased risk of PPHN: 33 of 11,014 exposed infants -
– (absolute risk 3 per 1000 liveborn infants compared with
the background incidence of 1.2 per 1000)
– Risks of PPHN for each SSRI (sertraline, citalopram,
paroxetine, and fluoxetine) were of similar magnitude
– Women who took an SSRI after 20 weeks had increased
risk of an infant with PPHN (OR 6.1; 95% CI, 2.2 to 16.8) –
Antidepressants and Neurodevelopment
• Antidepressant exposure during pregnancy does not
appear to have major adverse effects on indices of
early infant neurobehavioral development during the
first 2 months of life – Suri et al, 2011.
• Cohort Study comparing development of infants
exposed to tricyclic antidepressants, fluoxetine or
nothing in utero – Nulman et al, 2002
– Neither tricyclics nor fluoxetine adversely affected the
child’s global IQ, language development, or behavior.
– IQ was significantly and negatively associated with
– Language was negatively associated with number of
Antidepressants and fetal growth
• Case-control study looking at babies born small-for-gestational age – Ramos et al, 2010 • Venlafaxine (Effexor) of the serotonin-norepinephrine reuptake inhibitor (SNRI) class use in the second trimester was associated with SGA (OR 2.55; 95% CI 1.04 to 6.27) • SSRI and tricyclic antidepressants not associated with SGA
Bupropion (Wellbutrin)
• Case control study of 1213 infants with 1st TM
bupropion exposure showed no evidence of teratogenic effect – Cole et al, 2007
• Prospective cohort study of 136 women exposed
– no increased risk of major malformation
– increased risk of miscarriage similar to rates of other
antidepressants – 20 (14.7%) Bupropion vs 6 (4.5%) control; p =.009 – Chun-Fai-Chan et al, 2005
• Formerly class B, recategorized as C in 2006
Mood Stabilizers
– Increased incidence of congenital defects when
– Use in second and third trimester associated with
– Higher risk of spina bifida – Associated with intrauterine growth retardation,
hyperbilirubinemia, hepatotoxicity, skeletal
Anxiolytics
– Limited data reveal no increased risk of teratogenic
– Major neonatal side effects including sedation and
– Some early studies concern for teratogenicity though
– Shorter acting benzodiazepines preferred agents – More data needed: Patients can enrol in the AED
Pregnancy Registry by calling 1-888-233-2334 or visit
Risk of Stopping Antidepressants in Pregnancy
• Prospective cohort study of 201 pregnant women with a
history of pre-pregnancy major depression – Cohen et al,
– Women who discontinued medication were 5 times as likely to
relapse as compared to women who maintained their
antidepressant treatment across pregnancy (hazard ratio, 5.0;
• Women who stopped their antidepressant “cold turkey” in
pregnancy because fear of harming their baby had higher
rates of morbidity, hospitalization, suicidal ideation and
suicide attempts and lower compliance with medical
therapy and pregnancy management – Koren et al, 2012 Antidepressants for Postpartum
• Start treatment at half-doses for four days • Increase doses by small increments weekly as
• Slow increases helpful for side effects • If patient responds, continue same dose at least
• If no improvement after 6 weeks, or if response
• Average duration of a postpartum episode of
depression (without treatment) is seven months
Lactation and Antidepressants
• No controlled trials • Multiple case reports and case series • Many case reports are on 1-2 infants, short-term
• Studies measure infant serum levels • May not be indicative of infant brain levels
• Not necessarily related to patient-oriented
Lactation and Antidepressants
• No published reports of adverse effects in breast-
fed infants whose mothers took sertraline,
• Tricyclic antidepressants not typically found in
• Nortriptyline studied most in breast-feeding
• Children exposed to TCAs through breast milk
have no developmental problems thru school-age
Fluoxetine and Lactation
• Colic reported in three infants breast-fed by mothers
– infants had serum levels of fluoxetine and norfluoxetine
(the active metabolite of fluoxetine) in adult therapeutic
– Unlike most antidepressants, fluoxetine has a highly active
metabolite (norfluoxetine), and both agents have very long
half-lives (84 and 146 hours, respectively)
• Chambers (1999) reported that breast-fed infants of
fluoxetine-treated mothers gained significantly less
• Hendrick (2003) no difference in weight related to
fluoxetine , but low weight was associated with long
period of maternal depression (>2 months)
• Psychosocial or psychotherapy reasonable for
• Weigh risks and benefits of antidepressant for
• SSRIs (except paroxetine) and tricyclic
antidepressants are first line in pregnancy
• Bupropion is reasonable second-line agent • Cessation of antidepressants associated with
higher rates of relapse and poorer pregnancy
