Taking Vivitrol While Pregnant: Is It Safe?

Medically Reviewed by Johnelle Smith, M.D. on May 27, 2022

Monthly-injection Vivitrol may be a safer option than some other treatments for opioid use disorder during pregnancy. However, this can only be determined by a health care provider based on a number of factors.

Can I Take Vivitrol While Pregnant?

Vivitrol has been classified as a category C prescription medication by the U.S. Food & Drug Administration (FDA).

Pregnancy category C medications show adverse effects in animal fetuses in reproductive studies.

In addition, there have been no controlled or adequate studies on the effects these medications have on human fetuses or pregnant women.

However, Vivitrol, and other pregnancy category C medications, have significant benefits.

Healthcare providers may decide that the benefits are worth the possible risks and continue medication during pregnancy.

Effect Of Vivitrol On Unborn Babies

Very limited research exists that explores the results that Vivitrol has on babies in utero. Babies born opioid-dependent stayed in the hospital fewer days when treated with naltrexone (the active ingredient in Vivitrol).

Rats exposed to naltrexone in the womb had behavioral and developmental issues as they aged, but birth weights were higher. In these studies, the amount of naltrexone was significantly higher than the recommended dose.

There has been limited evidence that revealed that Vivitrol, and other naltrexone products, travel across the placenta in humans.

Opioid Drug Treatment And Alcohol Treatment During Pregnancy

A healthcare provider may decide to continue to use Vivitrol if the benefits outweigh the risks.

Vivitrol helps maintain sobriety, and the risk associated with opioid or alcohol use during pregnancy is well-known.

Continuing to administer Vivitrol as part of a substance abuse treatment recovery program can help a pregnant individual stay sober.
