GENERIC NAME: finasteride tablets

BRAND NAME: Propecia (for male hair growth)

DRUG CLASS AND MECHANISM: Finasteride is a synthetic compound that is used for the treatment of male pattern hair loss or androgenetic alopecia in males only. Finasteride blocks conversion of testosterone to dihydrotestosterone (DHT). Finasteride decreases the blood and scalp concentrations of DHT which is thought to be associated with androgenetic alopecia.

Propecia (1 mg finasteride) was approved by the FDA for the treatment of male pattern baldness in December 1997. Another finasteride oral dosage form, Proscar or 5 mg finasteride tablets are FDA approved only for the treatment of benign prostatic hyperplasia (BPH) and should not be used for androgenetic alopecia. Do not confuse these finasteride tablets.

PRESCRIPTION: Yes

GENERIC AVAILABLE: Yes

PREPARATIONS: Tablets: 1 mg (Caution; do not confuse these tablets with the 5 mg finasteride tablets (Proscar)

STORAGE: Tablets should be stored at room temperature, 15 C-30 C (59 F-86 F).

PRESCRIBED FOR: Finasteride (Propecia) is used for the treatment of male pattern baldness or androgenetic alopecia in males only.

DOSING: The recommended dose is one 1 mg tablet (Propecia) once daily. Generally, patients should use 1 mg of finasteride daily for three months or more before any benefits of treatment are observed. If hair loss improvement is not noticed after 12 months, additional finasteride treatments will likely not help.
