Uses
Silodosin is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia; BPH), which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. Silodosin is in a class of medications called alpha-blockers. It relieves the symptoms of BPH by relaxing the muscles of the bladder and prostate.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with silodosin, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- tell your doctor if you have kidney or liver disease. Your doctor will probably tell you not to take silodosin.
- tell your doctor if you have or have ever had low blood pressure.
- you should know that silodosin is only for use in men. Women should not take silodosin, especially if they are or could become pregnant or are breast-feeding. If a pregnant woman takes silodosin, she should call her doctor.

- you should know that silodosin may make you drowsy or dizzy, especially when you first start taking it. Do not drive a car or operate machinery until you know how this medication affects you.
- you should know that silodosin may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking silodosin. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up. If you experience these symptoms, sit or lie down. If these symptoms do not improve, call your doctor.
Dosage Of Silodosin
Silodosin comes as a capsule to take by mouth. It is usually taken with food once a day. Do not take silodosin on an empty stomach. Take silodosin 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 silodosin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Silodosin controls the symptoms of BPH but does not cure it. Continue to take silodosin even if you feel well. Do not stop taking silodosin 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.
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.
