Alfuzosin
Summary
Alfuzosin is a medication used to treat the symptoms of an enlarged prostate in adult men. It is not intended for use by women or children.
Alfuzosin works by relaxing the muscles around the bladder and prostate, which helps urine flow more easily. It does not typically affect weight, appetite, or eating behaviors.
Alfuzosin is typically administered as extended-release tablets taken with food and the same meal each day. The tablets should not be crushed or chewed as they are designed to release the medication slowly over time.
Common side effects of Alfuzosin include dizziness, headaches, and fatigue. Other side effects include upper respiratory tract infection, abdominal pain, and nausea. Serious side effects include a sudden drop in blood pressure and a painful, long-lasting erection known as priapism.
Alfuzosin can lower blood pressure, especially when first taken, which could cause dizziness or fainting. It should not be taken if you have liver problems, are taking certain antifungal or anti-HIV medicines, or are allergic to Alfuzosin. It is important to avoid driving or operating machinery until you know how Alfuzosin affects you.
