What is Propecia?


Propecia« (finasteride) is a prescription medicine used for the treatment of male pattern baldness - a hereditary condition caused by an excess of hormones called androgens. Propecia« works by decreasing the production of these hormones.

Propecia« dosage

The recommended dose of Propecia« is 1mg once daily with or without meals. In general, daily use for three months or more is needed before a change in hair loss is obvious. It may take up to six months before hair regrows. Propecia does not work for everyone. In medical research studies, it stopped hair loss and caused some regrowth in about 60 percent of men who used it for 12 months. If no effect is seen by 12 months, the drug will probably not work for you.

Propecia« side effects

Side effects with Propecia« have been reported by fewer than one in 50 (2%) of men treated. Side effects may include dizziness, headache, abdominal pain, decreased sex drive, impotence, swollen or tender breasts and decreased volume of ejaculate. You should contact your doctor immediately if you experience any rare side effects from Propecia« such as a skin rash, hives or swelling of the face or lips. Children or women should not use Propecia«. Women who are pregnant or those who may become pregnant should not take or handle this drug because there is a risk of birth defects in male babies.
