Tocainide Pregnancy and Breastfeeding Warnings

Tocainide is also known as: Tonocard

Tocainide Pregnancy Warnings

Tocainide has been assigned to pregnancy category C by the FDA. Animal studies using dosages 1 to 12 times that recommended in humans (on a per kg basis) failed to reveal evidence of teratogenicity. An increase in abortions, stillbirths and decreased offspring survival within the first week postpartum was noted. There are no controlled data in human pregnancy. Tocainide should be given during pregnancy only when benefit outweighs risk.
