Finasteride (Proscar) is used alone or in combination with another medication (doxazosin [Cardura]) to treat benign prostatic hypertrophy (BPH, enlargement of the prostate gland). Finasteride is used to treat symptoms of BPH such as frequent and difficult urination and may reduce the chance of acute urinary retention (sudden inability to urinate). It also may decrease the chance that prostate surgery will be needed. Finasteride (Propecia) is also used to treat male pattern hair loss (gradual thinning of the hair on the scalp, leading to a receding hairline or balding on the top of the head in men.) Finasteride (Propecia) has not been shown to treat thinning hair at the temples and is not used to treat hair loss in women or children. Finasteride is in a class of medications called 5-alpha reductase inhibitors. Finasteride treats BPH by blocking the body's production of a male hormone that causes the prostate to enlarge. Finasteride treats male pattern hair loss by blocking the body's production of a male hormone in the scalp that stops hair growth.

Finasteride comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take finasteride at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take finasteride exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you are taking finasteride to treat BPH, you should know that finasteride may control your condition, but will not cure it. It may take at least 6 months before your symptoms improve. Continue to take finasteride even if you feel well. Do not stop taking finasteride without talking to your doctor.
If you are taking finasteride to treat male pattern hair loss, it may take at least 3 months before you see any improvement because hair loss and growth happen slowly over time. However, you should expect to see improvement during the first 12 months of your treatment. If you have taken finasteride for 12 months and have not noticed any improvement, further treatment probably will not help. Talk to your doctor about whether you should continue your treatment.
Finasteride will only slow hair loss while you are taking the medication. Continue to take finasteride even if you have already noticed an improvement. Do not stop taking finasteride without talking to your doctor. You will probably lose any hair that grew back while you were taking finasteride during the first 12 months after you stop taking the medication..
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

Taking finasteride may increase the risk that you will develop high-grade prostate cancer (a type of prostate cancer that spreads and grows more quickly than other types of prostate cancer). Talk to your doctor about the risks of taking finasteride.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them.  However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community.  See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to finasteride.
Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking finasteride.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
