Guaifenesin / hydrocodone / pseudoephedrine Pregnancy Warnings

Use is not recommended unless the benefit outweighs the risk to the fetus

US FDA pregnancy category: C

Comments: Prolonged use of opioids during pregnancy can result in physical dependence in the neonate; women should be advised of the risk of neonatal abstinence syndrome and ensure that appropriate treatment will be available.

Animal studies have not been conducted with this combination product, but studies have shown teratogenicity in hamsters with hydrocodone doses approximately 35 times the maximum recommended human daily dose. Babies born to mothers taking opioids regularly during pregnancy may become physically dependent. Opioids given to the mother shortly before delivery may produce some degree of respiratory depression in the newborn, especially if high doses are used. There are no controlled data in human pregnancy.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
