Alfuzosin

(al fyoo' zoe sin)

Brand Name(s): Uroxatral®; also available generically

WHY is this medicine prescribed?

Alfuzosin is used in men to treat symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH), which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. Alfuzosin is in a class of medications called alpha blockers. It works by relaxing the muscles in the prostate and bladder to allow urine to flow more easily.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Alfuzosin comes as an extended-release (long-acting) tablet to take by mouth. It is usually taken once a day, immediately after a meal. Do not take alfuzosin on an empty stomach. To help you remember to take alfuzosin, take it after the same meal 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 alfuzosin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them.

Alfuzosin controls BPH but does not cure it. Continue to take alfuzosin even if you feel well. Do not stop taking alfuzosin without talking to your doctor.

What SPECIAL PRECAUTIONS should I follow?

  • tell your doctor and pharmacist if you are allergic to alfuzosin, any other medications, or any of the ingredients in alfuzosin. Ask your pharmacist for a list of the ingredients.

  • The following nonprescription product may interact with alfuzosin: cimetidine (Tagamet).

What should I know about STORAGE and DISPOSAL of this medication?

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 light and excess heat and moisture (not in the bathroom).

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.

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

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.
