Important Information About PROPECIA
 
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.
 
PROPECIA is contraindicated in patients with hypersensitivity to any component of this medication.
 
Women should not handle crushed or broken PROPECIA tablets when they are pregnant or may potentially be pregnant because of the possibility of absorption of finasteride and the subsequent potential risk to a male fetus. PROPECIA tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets have not been broken or crushed.
