Is Combivent safe for pregnant or breast-feeding women?

The Food and Drug Administration has given Combivent pregnancy category C, meaning its effects on a developing fetus are unknown. Likewise, it is not known if the medications in Combivent can be passed to a nursing baby, or if they do whether they'd cause any harm. If you are currently breast-feeding, pregnant, or planning to become pregnant and taking Combivent, talk to your doctor before continuing with the medication.
