Proscar is a prescription medicine used to treat enlarged prostate in men. Proscar belongs to a group of drugs called 5-alpha reductase inhibitors. It works by blocking the body's production of the male hormone that causes the prostate to enlarge.

Proscar may increase the chance of a more serious form of prostate cancer.

The most common side effects of Proscar include:

• trouble getting or keeping an erection (impotence)
• decrease in sex drive
• decreased volume of ejaculate
• ejaculation disorders
• enlarged or painful breast. You should promptly report to your doctor any changes in your breasts such as lumps, pain or nipple discharge

In addition, the following have been reported in general use with Proscar:

• allergic reactions, including rash, itching, hives, and swelling of the lips and face
• rarely, some men may have testicular pain
• in rare cases, male breast cancer has been reported.

You should discuss side effects with your doctor before taking Proscar and anytime you think you are having a side effect. These are not all the possible side effects with Proscar. For more information, ask your doctor or pharmacist.

Call your doctor for medical advice about side effects. You may report side effects to FDA at: 1-800-FDA-1088.

No Proscar drug interactions have been identified, however, you should tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Not all drug interactions are known or reported and new drug interactions are continually being reported.

Do Not Take Proscar if you are:

• a woman who is pregnant or may potentially be pregnant. Proscar may harm your unborn baby. Do not touch or handle crushed or broken Proscar tablets.
• allergic to Proscar or any of the ingredients in Proscar tablets.

Important information about Proscar:

• You should see your doctor regularly while taking Proscar. Follow your doctor's advice about when to have these checkups.
• Checking for prostate cancer. Your doctor has prescribed Proscar for BPH and not for treatment of prostate cancer — but a man can have BPH and prostate cancer at the same time. Checking for prostate cancer should continue while you take Proscar.
• About Prostate-Specific Antigen (PSA). Your doctor may have done a blood test called PSA for the screening of prostate cancer. Because Proscar decreases PSA levels, you should tell your doctor(s) that you are taking Proscar. Changes in PSA levels will need to be evaluated by your doctor(s). Any increase in follow-up PSA levels from their lowest point may signal the presence of prostate cancer and should be evaluated, even if the test results are still within the normal range. You should also tell your doctor if you have not been taking Proscar as prescribed because this may affect the PSA test results. For more information, talk to your doctor.

Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Proscar there are no specific foods that you must exclude from your diet when receiving Proscar.

Before taking Proscar, tell your healthcare provider if you: have any other medical conditions, including problems with your prostate or liver.

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

A warning about Proscar and pregnancy:

Women who are or may potentially be pregnant must not use Proscar. They should also not handle crushed or broken tablets of Proscar tablets. Proscar tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed.

If a woman who is pregnant with a male baby absorbs the active ingredient in Proscar tablets after oral use or through the skin, it may cause the male baby to be born with abnormalities of the sex organs. If a woman who is pregnant comes into contact with the active ingredient in Proscar tablets, a doctor should be consulted.

Proscar is not approved for use in women.

It is not known whether Proscar is excreted in human milk or if it will harm your nursing baby.

Follow your doctor's instruction.

• Take one tablet by mouth each day. To avoid forgetting to take Proscar, you can take it at the same time every day.
• If you forget to take Proscar, do not take an extra tablet. Just take the next tablet as usual.
• You may take Proscar with or without food.
• Do not share Proscar with anyone else; it was prescribed only for you.

For the treatment of BPH the recommended dose of Proscar is one tablet (5 mg) taken once a day.

If you take too much Proscar, call your local Poison Control Center or seek emergency medical attention right away.
