This medication description is not meant for treatment prescription without the intervention of a specialist.

Common Uses

Proscar is prescribed to help shrink an enlarged prostate. The prostate, a chestnut-shaped gland present in males, produces a liquid that forms part of the semen. This gland completely encloses the upper part of the urethra, the tube through which urine flows out of the bladder. Many men over age 50 suffer from a benign (noncancerous) enlargement of the prostate. The enlarged gland squeezes the urethra, obstructing the normal flow of urine. Resulting problems may include difficulty in starting urination, weak flow of urine, and the need to urinate urgently or frequently. Sometimes surgical removal of the prostate is necessary. By shrinking the enlarged prostate, Proscar may alleviate the various associated urinary problems, making surgery unnecessary. Some doctors are also prescribing Proscar for baldness and as a preventive measure against prostate cancer.

How to Take

The recommended dosage, for men only, is one 5-milligram tablet per day.

Warning and Precautions

Proscar may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Proscar with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

Proscar may cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.

Proscar may increase the risk of certain birth defects, including abnormal formation of genitalia in male fetuses. Proscar is coated to prevent contact with finasteride while handling undamaged tablets. The coating is not effective if the tablets are damaged, broken, or crushed. Women who are pregnant or may be pregnant should avoid contact with damaged, broken, or crushed tablets. If contact occurs, tell your doctor at once.
