Pregnancy and Breastfeeding with Onsolis

Inform your doctor if you are pregnant or intend to become pregnant before taking Onsolis. Onsolis should be used only as directed during pregnancy. If used during the first two months of pregnancy, it may modestly raise the chance of birth abnormalities. Using it close to the predicted delivery date may be harmful to the fetus. Inform your doctor if your newborn baby exhibits signs such as slow or shallow breathing, irritability, abnormal or consistent crying, vomiting, or diarrhea. This medication goes into breast milk and may have unfavorable effects on a breastfeeding newborn in rare cases. Inform your doctor if your infant develops unusual lethargy, difficulty eating, or breathing difficulties. Before you start nursing, talk to your doctor. If you suddenly stop taking medication, you may experience withdrawal symptoms.

If you have any of the symptoms described above, get medical attention immediately.
