Can I take Dilt-CD (diltiazem) while I am pregnant or breast-feeding?

No adequate or well-controlled studies have been done in humans of the use of Dilt-CD during pregnancy and breastfeeding. However, animal studies suggest that Dilt-CD may not be safe for use during pregnancy or breastfeeding. If you are pregnant or breastfeeding, talk to your doctor about the potential risks to the fetus or nursing infant, before taking Dilt-CD.
