Alfuzosin

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.

Dosage

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.

Other

Keep all appointments with your doctor.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription of alfuzosin.

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.
