"What are the possible side effects of PROPECIA?
Like all prescription products, PROPECIA may cause side effects. In clinical studies, side effects from
PROPECIA were uncommon and did not affect most men. A small number of men experienced certain
sexual side effects. These men reported one or more of the following: less desire for sex; difficulty in
achieving an erection; and, a decrease in the amount of semen. Each of these side effects occurred in
less than 2% of men. These side effects went away in men who stopped taking PROPECIA. They also
disappeared in most men who continued taking PROPECIA.
In general use, the following have been reported: breast tenderness and enlargement; depression;
allergic reactions including rash, itching, hives and swelling of the lips and face; problems with
ejaculation; testicular pain; and, in rare cases, male breast cancer. You should promptly report to your
doctor any changes in your breasts such as lumps, pain or nipple discharge. Tell your doctor promptly
about these or any other unusual side effects."
