Propecia 5 Year Results

Highlights of Clinical Studies

5 years of clinical data showed the benefit of PROPECIA® (finasteride)

Measurements of hair counts in a 1" diameter circle in 2 vertex studies showed that ...

PROPECIA works for most men: Most (65%) men treated with PROPECIA at Year 5 had increased hair count, while all men in the placebo group lost hair.

Men who started treatment with placebo and were switched to PROPECIA 1 year later never caught up to the men who were treated with PROPECIA for the full 5 years.

The maximum improvement in hair count with PROPECIA compared to baseline was achieved during the first 2 years.

Further treatment is unlikely to be of benefit if the drug has not worked within 12 months.

Stopping treatment leads to a gradual reversal of the beneficial effects within 12 months.
