If I am pregnant, is it safe to use Onsolis?

The cancer pain medication Onsolis (fentanyl) may be risky during pregnancy, so experts say you should use it only if you and your doctor decide the benefits outweigh the potential dangers. Onsolis hasn't been studied adequately in pregnant women, but animal studies suggest it may sometimes cause problems for the developing fetus. Although no birth defects have been reported when pregnant women used Onsolis, fentanyl has been linked to temporarily slowed breathing, behavioral changes and seizures in newborn infants.

You should not take Onsolis during labor and delivery, because the drug may slow breathing in your newborn infant.
