According to WebMD, Biogesic should only be used by pregnant women if absolutely necessary. There is insufficient human and animal data about the potential side effects.
WebMD states that those who are breastfeeding only excrete low levels of the drug, and there is a low risk of negative effects for the infant. Biogesic should still be used with caution by nursing mothers as there has not been enough data collected about the effects the drug has on infants.
WebMD explains that Biogesic is a combination of acetaminophen and an antihistamine. It is typically used to treat cold symptoms, allergies or as a nighttime sleep aid.
