PROSCAR is used to treat symptoms of benign prostatic hyperplasia (BPH) in men with an enlarged prostate.
Warnings and Precautions
Women who are or may potentially be pregnant must not use PROSCAR. They should also not handle crushed or broken tablets of PROSCAR. If the active ingredient in PROSCAR is absorbed after oral use or through the skin by a woman who is pregnant with a male baby, it may cause the male baby to be born with abnormalities of the sex organs. PROSCAR tablets are coated and will prevent contact with the active ingredient during normal handling provided that the tablets are not broken or crushed. If a woman who is pregnant comes into contact with the active ingredient in PROSCAR, a physician should be consulted.
You must see your physician regularly while taking PROSCAR. Follow your physician’s advice about when to have these checkups.
