When should I start PROPECIA?
Start
Five years of clinical data with PROPECIA show the sooner you start, the better.
If you have MPHL, the sooner you get started on PROPECIA, the more hair you may have later. In fact, in the longest reported controlled study of male pattern hair loss ever conducted, men who were treated with a placebo (sugar pill) and then switched to PROPECIA 1 year later never caught up to the men who took PROPECIA for the full 5 years.
If you stop taking PROPECIA, you will likely lose the hair you have gained within 12 months of stopping treatment.
In the first year of the study, 86% (584 of 679) of the men on PROPECIA maintained hair or increased the number of visible hairs vs 42% (282 of 672) of the men on placebo.
PROPECIA is the first and only FDA-approved pill used for the treatment of male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head). There is not sufficient evidence that PROPECIA works for receding hairlines at the temples. PROPECIA is for use by MEN ONLY and should NOT be used by women or children.
In clinical studies for PROPECIA, a small number of men experienced certain sexual side effects, such as less desire for sex, difficulty in achieving an erection, or a decrease in the amount of semen. Each of these side effects occurred in less than 2% of men and went away in men who stopped taking PROPECIA because of them.
