Is bupropion (Wellbutrin) safe during pregnancy?

This is a great question. Unfortunately, there is not a simple answer. Bupropion (Wellbutrin) is not completely risk free, but neither is untreated maternal illness. Women should decide whether or not to take bupropion during pregnancy after consultation with a perinatal psychiatric specialist. Together, they can evaluate the risks and benefits of taking bupropion after considering the woman’s personal psychiatric history, preferences, and values.

Untreated maternal mental illness

Women with a history of depression who stop taking their antidepressant have a 70% chance their depression recurring during pregnancy (compared to a 25% chance for women who continue taking their antidepressant).[i] Depression during pregnancy has been linked to increased rates of miscarriage and exposure of a developing fetus to stress.[ii] It has also been linked to an increased risk of postpartum depression, which, in turn, can affect a mother’s bonding with her baby, her ability to tolerate breastfeeding, and her attention to her baby’s safety.[iii]

Mental illness during pregnancy is risky, often—but not always—more risky than the use psychiatric medications.

Benefits of bupropion in women with depression
Bupropion is an antidepressant with similar efficacy to most other antidepressants. However, it is in its own class and has a different side effect profile. It may be less effective for anxious depression than SSRIs. On the other hand, rather than causing dysfunction, some women may find it to be beneficial when it comes to sex. While SSRIs are better studied and are considered preferred antidepressants during pregnancy, bupropion is a reasonable choice when women have not fully responded to an SSRI, have been unable to tolerate an SSRI, or have benefited from bupropion in the past.[iv]

Risks of bupropion

Prior to pregnancy

  • Side effects
    Bupropion is generally well tolerated. It can cause insomnia and weight loss. Seizures have been reported but are rare.[v]
  • Fertility
    There is no strong evidence that suggests bupropion impairs fertility.[vi]

During pregnancy

  • Miscarriage
    There is not sufficient evidence to conclude that there is an association between bupropion and miscarriage. One study suggested that there might be, but the study had serious flaws in its design. Rates of miscarriage were similar between women on bupropion and other antidepressants, suggesting that depression, not bupropion, might be responsible for the possible increased risk.[vii]
  • Congenital defects
    While there are studies that suggest that bupropion may be associated with cardiac defects, other studies, including the study likely to be the best study, suggest that there is no association.[viii]
  • Gestational hypertension and preeclampsia
    Bupropion is not associated with gestational hypertension or preeclampsia.[ix]
  • Preterm birth
    Bupropion is not associated with preterm birth.[x]
  • Low birth weight
    Bupropion is not associated with low birth weight.[xi]

At delivery

  • Postpartum hemorrhage
    Bupropion is not associated with postpartum hemorrhage.[xii]

After delivery

  • Future development of the baby
    One study suggested that a mother’s use of bupropion during pregnancy may be associated with her child later developing ADHD. This study has severe methodologic limitations and has not been replicated.[xiii]
  • Breastfeeding
    Women on bupropion may breastfeed. The amount the infant would be expected to consume through breastmilk is quite low and is often undetectable in the infant’s blood.[xiv]

Summary

Bupropion during pregnancy are not entirely risk free, but neither is untreated maternal mental illness. Women should decide whether or not to take bupropion during pregnancy after consultation with a perinatal psychiatric specialist. Together, they can evaluate the risks and benefits of taking bupropion after considering the woman’s personal psychiatric history, preferences, and values.
