Amantadine Pregnancy and Breastfeeding Warnings

Amantadine is also known as: Symmetrel

Amantadine Pregnancy Warnings

Amantadine has been assigned to pregnancy category C by the FDA. Some animal studies have revealed evidence of embryotoxicity and teratogenicity using doses 12 times the recommended human dose. There are no controlled data in human pregnancy. A cardiovascular birth defect (single ventricle with pulmonary atresia) was reported in an infant whose mother had taken 100 mg/day during the first 2 weeks of pregnancy. Tetralogy of Fallot and tibial hemimelia was reported in an infant whose mother took 100 mg/day for 1 week during the sixth and seventh week of pregnancy. Amantadine should only be given during pregnancy when benefit outweighs risk.
