Hydrochlorothiazide / propranolol Pregnancy Warnings

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.

US FDA pregnancy category: C

Animal studies with hydrochlorothiazide have failed to reveal evidence of fetal harm. Animal studies with propranolol have revealed evidence of neonatal death and embryotoxicity. There are no controlled data in human pregnancy; however, intrauterine growth retardation, small placentas, and congenital abnormalities have been reported in human neonates whose mothers received propranolol during pregnancy. Neonates whose mothers received propranolol at parturition have exhibited bradycardia, hypoglycemia, and/or respiratory depression.

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.
