Uses
Tamsulosin is used in men to treat the 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. Tamsulosin is in a class of medications called alpha-blockers. It works by relaxing the muscles in the prostate and bladder so that urine can flow easily.

- tell your doctor if you have or have ever had prostate cancer or liver or kidney disease.
- you should know that tamsulosin is only for use in men. Women should not take tamsulosin, especially if they are pregnant or could become pregnant or are breast-feeding. If a pregnant woman takes tamsulosin, she should call her doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking tamsulosin. If you need to have eye surgery at any time during or after your treatment, be sure to tell your doctor that you are taking or have taken tamsulosin.
- you should know that this medication may make you drowsy or dizzy. Do not drive a car, operate machinery, or perform dangerous tasks until you know how this medication affects you.
- you should know that tamsulosin may cause dizziness, lightheadedness, a spinning sensation, and fainting, especially when you get up too quickly from a lying position. This is more common when you first start taking tamsulosin or after your dose is increased. To help avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up. Call your doctor if these symptoms are severe or do not go away.
Tamsulosin Dosage
Tamsulosin comes as a capsule to take by mouth. It is usually taken once a day. Take tamsulosin 30 minutes after the same meal each day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tamsulosin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow tamsulosin capsules whole; do not split, chew, crush, or open them.
Your doctor will probably start you on a low dose of tamsulosin and may increase your dose after 2 to 4 weeks.
Tamsulosin may help control your condition, but it will not cure it. Continue to take tamsulosin even if you feel well. Do not stop taking tamsulosin 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.
