Tamsulosin Sandoz SR is for use by men only.

This medicine is used for the relief of lower urinary tract symptoms (LUTS) associated with a condition called benign prostatic hyperplasia (BPH). BPH is NOT prostate cancer. BPH is a condition where your prostate gland (which is near your bladder) has become bigger making it more difficult for you to pass urine. This can lead to symptoms such as:

  • weak or interrupted stream of urine
  • delay before you start to pass urine, and you have to strain to do so.
  • feeling that you cannot empty your bladder completely
  • may dribble at the end of passing urine.
  • needing to pass urine often, especially at night
  • feeling that you must pass urine right away.

BPH occurs only in men and is common over the age of 50 years. In some men, BPH can lead to serious problems, including urinary tract infections and the sudden inability to pass urine at all.

This medicine contains the active ingredient tamsulosin hydrochloride. Tamsulosin hydrochloride belongs to a group of medicines called alpha-blockers.

Tamsulosin Sandoz SR works by helping relax the smooth muscles in the prostate, in that way it improves the flow of urine, thus relieving the pain when passing urine.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.
