Pain Home > Subsys and Pregnancy
During animal studies, the active ingredient in Subsys (fentanyl sublingual spray) appeared to increase the risk for miscarriage, but did not cause any birth defects. This drug can be given to a pregnant woman if the benefits outweigh the risks. However, it should be noted that withdrawal symptoms, such as decreased breathing, could occur in a newborn whose mother took Subsys during pregnancy.
