PROPECIA is the Only FDA-Approved once-a-day pill proven to help reduce DHT, a key cause of hair loss.
Possible side effects of PROPECIA®
PROPECIA was developed to treat mild to moderate male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head) in MEN ONLY. There is not sufficient evidence that PROPECIA works for receding hairlines at the temples.

Important Information About PROPECIA

PROPECIA is for the treatment of male pattern hair loss in MEN ONLY and should NOT be used by women or children.

You should not use PROPECIA if you are allergic to finasteride or any of the ingredients in PROPECIA.

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.
Clinical studies showed that side effects were uncommon and did not affect most men.
In general use, the following side effects have been reported: allergic reactions including rash, itching, hives, and swelling of the lips and face; problems with ejaculation; breast tenderness and enlargement; and testicular pain. You should promptly report to your doctor any changes in your breasts such as lumps, pain, or nipple discharge. Tell your doctor about these or any other unusual side effects.

A small number of men had sexual side effects, with each occurring in less than 2% of men. These include less desire for sex, difficulty in achieving an erection, and a decrease in the amount of semen. These side effects went away in men who stopped taking PROPECIA because of them. In addition, these side effects decreased to 0.3% of men or less by the fifth year of treatment.

In 3 controlled clinical trials for PROPECIA of 12-month duration, 1.4% of patients who took PROPECIA (n=945) were discontinued due to adverse experiences that were considered to be possibly, probably, or definitely drug related. 1.6% of patients who took a sugar pill (placebo; n=934) were discontinued due to adverse experiences.
PROPECIA can affect a blood test called PSA (prostate-specific antigen) for the screening of prostate cancer. If you have a PSA test done, tell your doctor that you are taking PROPECIA.
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.

In addition, some men may have breast enlargement and/or tenderness. You should promptly report to your doctor any changes in your breasts such as lumps, pain, or nipple discharge.
