    Dr. Lee Cohen in Ob-Gyn News: Using SSRIs in Pregnancy

    Over the last decade, attention in the medical literature has gathered logarithmically to focus on potentially efficacious treatments for perinatal depression. Studies of relevant databases, editorials, and various reviews have addressed the reproductive safety concerns of antidepressant treatments, particularly selective serotonin reuptake inhibitors (SSRIs) on one hand, and the impact of untreated maternal psychiatric illness on fetal and maternal well-being on the other.

    SSRIs and Pregnancy: Putting the Risks and Benefits into Perspective

    Prozac hit the market in 1988, the first selective serotonin reuptake inhibitor (SSRI) antidepressant approved by the FDA for the treatment of depression.  Because it was safer and more tolerable than the antidepressants that preceded it, Prozac was soon the most commonly prescribed antidepressant in the United States.

    Topiramate (Topamax) Associated with an Increased Risk of Oral Clefts

    Topiramate (marketed as a Topamax), in addition to its use for the treatment of epilepsy, is now being prescribed to reproductive aged women for a broad spectrum of indications, including migraine headaches, weight control, and mood stabilization.  Limited information is available on its reproductive safety; however, the preliminary data we do have raises some concerns regarding the use of topiramate in pregnancy.

    SSRIs and PPHN: The FDA Revises Its Warning

    In 2006, Chambers and colleagues published an article in the New England Journal of Medicine linking SSRI use during late pregnancy to an increased risk of persistent pulmonary hypertension in the newborn (PPHN).   Based on these findings, the “Usage in Pregnancy” section on the labels for SRRI antidepressants was updated to include the following warning: “Infants exposed to SSRIs in late pregnancy may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN).”

    New FDA Warning on the Use of Antipsychotic Medications in Pregnancy

    On February 22, 2011, the U.S. Food and Drug Administration (FDA) informed healthcare professionals that drug labels for the entire class of antipsychotic drugs have been updated to include warnings regarding the use of antipsychotic drugs during pregnancy. The new drug labels now contain more details on the potential risk for abnormal muscle movements (extrapyramidal signs or EPS) and withdrawal symptoms in newborns exposed to these drugs during the third trimester of pregnancy.

    Should SSRIs Be Tapered Prior To Delivery?

    Increased muscle tone, jitteriness, sleep disturbance, irritability, feeding problems, mild respiratory distress and myoclonus have been reported as symptoms of a potential neonatal distress syndrome related to exposure to SSRIs in late pregnancy.  The average duration of symptoms reported is 48 hours.  It is estimated that between 25-30% of SSRI-exposed infants are at risk for this syndrome.  No treatment intervention is required.  Reassuringly, follow-up studies have shown that at 2, 4, 6, and 8 months SSRI-exposed infants are indistinguishable from control infants without known exposure.

    Antidepressants and Risk of Spontaneous Abortion

    Although the last several decades of research have yielded important findings regarding the safety of antidepressants during pregnancy, some areas are still understudied.  For example, there are no conclusive results concerning the risk of spontaneous abortions following antidepressant exposure during the first trimester.  Several recent meta-analyses, including one from the Motherisk program (Hemels, 2005), have observed an increased risk of spontaneous abortion among women taking antidepressants.

    Valproic Acid and the Risk of Major Malformations

    Previous studies have indicated that infants exposed to valproic acid in pregnancy are at increased risk for a range of malformations, including neural tube defects.  While these studies have shown an association between valproic acid and various malformations, they have been limited in their ability to quantify the risk of certain, less common malformations.  To do this, large population-based case–control studies are more appropriate.
