Proscar
Description: By the time men reach about age 50, the prostate may start causing problems. Urinary symptoms begin to trouble many men as they reach middle age. The most common source of symptoms is the prostate gland. More specifically, it is the growth of the prostate gland in some men that can cause urinary tract problems.
PROSCAR is a medication that helps shrink the prostate in many men. This can lead to improvement of symptoms. You may need to take PROSCAR for 6 months or more to see whether it improves your symptoms. PROSCAR has been shown to reduce the risk of a sudden inability to pass urine, referred to as acute urinary retention, and the need for surgery—potential long-term serious consequences of benign prostatic hyperplasia (BPH).
Important Information: PROSCAR is for use by MEN ONLY. Women who are or may potentially be pregnant must NOT use PROSCAR and should not handle crushed or broken tablets of PROSCAR because of the risk of a specific kind of birth defect.
PROSCAR may cause side effects. Side effects due to PROSCAR may include impotence (an inability to have an erection) or less desire for sex. Some men taking PROSCAR may have changes or problems with ejaculation, such as a decrease in the amount of semen released during sex. This decrease in the amount of semen does not appear to interfere with normal sexual function. In some cases these side effects went away while the patient continued to take PROSCAR. 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.
