Propecia® (finasteride) is an oral medication used for the treatment of male hair loss. It is available by prescription only.
Propecia® may halt or reduce hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of the head).
What are the clinical uses of Propecia®?
Propecia® is often prescribed to men who are beginning to experience male pattern hair loss. Clinical studies of men who took Propecia® regularly for two years found that more than 95% had visible results of either new hair growth or no additional hair loss.
How does Propecia® work?
Male pattern hair loss is associated with the production of a hormone called dihydrotestosterone (DHT) in the scalp. DHT shrinks hair follicles until there are fewer visible hairs left on the scalp. Propecia® works by inhibiting the 5-alpha reductase enzyme that helps make DHT, which reduces the levels of DHT in the scalp.
How is Propecia® taken?
Propecia® is an oral medication to take by mouth. It is usually taken once a day.
Propecia® is for the treatment of male pattern hair loss in men only and should not be used by women or children.
You may need to take Propecia® daily for 3 months or more before you see a any benefit. If Propecia® has not worked for you within 12 months, further treatment is unlikely to be helpful.
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.
Take Propecia® exactly as directed by your doctor. Do not take more or less of it, or take it more often than prescribed by your doctor.
