PROPECIA is the first oral therapy indicated for the treatment of male pattern hair loss in MEN ONLY. Safety and efficacy were demonstrated in men, aged 18 to 41, with mild to moderate hair loss of the vertex and anterior mid-scalp area. Efficacy in bitemporal recession has not been established.
 
PROPECIA is not indicated in women or children.
 
In clinical studies of 1 year for PROPECIA, each drug-related sexual adverse event occurred in less than 2% of men. Discontinuation due to drug-related sexual adverse experiences was 1.2% in the group treated with PROPECIA and 0.9% in the placebo-treated group. Reported drug-related sexual adverse experiences included decreased libido (1.8% vs 1.3%, placebo), erectile dysfunction (1.3% vs 0.7%, placebo), and ejaculation disorders (1.2% vs 0.7%, placebo), primarily decreased volume of ejaculate (0.8% vs 0.4%, placebo).
