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.
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.
Are there OTHER USES for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
