Important Information About PROPECIA

The effectiveness of PROPECIA was demonstrated in studies of men, aged 18 to 41, with mild to moderate hair loss at the top and middle front of the head. There is not sufficient evidence that PROPECIA works for receding hairlines at the temples.

PROPECIA is for the treatment of male pattern hair loss in 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.

Women who are or may potentially be pregnant must not use PROPECIA and should not handle crushed or broken PROPECIA tablets because the active ingredient may cause abnormalities of a male baby’s sex organs. If a woman who is pregnant comes into contact with the active ingredient in PROPECIA, a doctor should be consulted. PROPECIA tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed.

You may need to take PROPECIA daily for 3 months or more before you see a benefit from taking PROPECIA. If PROPECIA has not worked for you within 12 months, further treatment is unlikely to be of benefit. 

PROPECIA can only work over the long term if you continue taking it. If you stop taking PROPECIA, you will likely lose any hair you have gained within 12 months of stopping treatment.

Although results will vary, generally you will not be able to grow back all the hair you have lost.

Know the facts. PROPECIA is available by prescription only, so the best thing to do is talk to your doctor.
