Identification and Treatment of Antenatal Depression Routine screening for antenatal depression is uncommon Identified antenatal depression is typically untreated or incompletely treated Prevalence of SSRI use during pregnancy is 3-7% SSRI = selective serotonin reuptake inhibitor.

Psychotropic Drug Use in Pregnancy n Drugs used when risk to mother and fetus from disorder outweighs risks of pharmacotherapy n Optimum risk/benefit decision for psychiatrically ill pregnant women n Patients with similar illness histories make different decisions regarding treatment during pregnancy n No decision is risk free Henshaw SK. Fam Plann Perspect. 1998;30(1):24-9,46.
Impact of Untreated Depression in Pregnancy n Some data support increased rates of obstetrical complications and poor neonatal outcome in depressed pregnant women Steer RA et al. J Clin Epidemiol

What is the safest antidepressant for women of childbearing age?
Psychotropic Drug Use in Pregnancy (cont’d) n Category Labeling: Does the current system inform clinical care? n Standard language: “use the medication in pregnancy when clearly needed”; when risk of treatment is outweighed by risk of underlying disorder
FDA Pregnancy Categories CategoryInterpretation A Controlled studies show no risk: Adequate, well-controlled studies in pregnant women have failed to demonstrate risk to the fetus. B No evidence of risk in humans: Either animal findings show risk, but human findings do not; or, if no adequate human studies have been done, animal findings are negative. C Risk cannot be ruled out: Human studies are lacking, and animal studies are either positive for fetal risk or lacking as well. However, potential benefits may justify the potential risk. D Positive evidence of risk: Investigational or postmarketing data show risk to the fetus. Nevertheless, potential benefits may outweigh risks. X Contraindicated in pregnancy: Studies in animals or humans, or investigational or postmarketing reports, have shown fetal risk that clearly outweighs any possible benefit to the patient.

Antidepressant Use During Pregnancy: Treatment Guidelines To discontinue or to maintain antidepressant treatment, consider: 1. Maternal illness history (past and present) 2. Patient wishes 3. Fertility status 4. Available reproductive safety data Cohen et al, CNS Spectrums, 2004 Expert Consensus Guidelines: Postgraduate Medicine
Antidepressant Use During Pregnancy: Treatment Guidelines (Cont.) n Switch antidepressant before or during pregnancy? Pregravid Switch to safest treatment that affords efficacy During pregnancy Avoid switching compounds
SSRI Use During Labor and Delivery: Treatment Implications n Treat across labor and delivery to minimize risk for puerperal illness n Depression during pregnancy strongest predictor of postpartum depression n Adverse effects of postpartum depression on infants and families

Treatment of Bipolar Disorder in Pregnancy: Mild to Moderate Bipolar Disorder Gradual taper and discontinuation of antimanic prophylaxis (lithium, sodium valproate) prior to pregnancy? Discontinuation of mood stabilizer after pregnancy is documented? Problematic with sodium valproate Reintroduce mood stabilizer as needed or during second trimester; concerns regarding reintroduction of sodium valproate given data suggesting behavioral teratogenicity. Cohen LS, J Clin Psychiatry 2007;68 ( suppl 9).
Treatment of Bipolar Illness During Pregnancy: What Is a Reasonable Strategy? Lithium may be the safest alternative for women dependent on mood stabilizers Lithium nonresponders Consider lamotrigine monotherapy Consider lamotrigine and typical or atypical antipsychotic Use of atypicals across pregnancy? Little role for monotherapy with typical antipsychotics Cohen LS, J Clin Psychiatry 2007;68 ( suppl 9).

Treatment of Mood Disorders During Pregnancy: What Have We Learned? Pregnancy is not protective with respect to new onset or recurrence of mood disorders Thoughtful treatment decisions can be made during pregnancy including those which involve use of psychotropics Weighing relative risks of pharmacologic treatment during pregnancy is best carried out on a case by case basis CONCLUSIONS
Treatment of Mood Disorders During Pregnancy: What Have We Learned? No decision is risk free No decision is perfect Patients and their clinicians will make treatment decisions based on perceived risk of pharmacologic therapy Importance of sustaining euthymia during pregnancy can not be overestimated CONCLUSIONS ( Continued)
Conclusions ( cont’d) Treatment of Mood Disorders During Pregnancy: What Have We Learned? New studies will likely refute current associations between antidepressant exposure and particular outcomes of concern and at the same time identify new ones
