What is tamsulosin used for?

Flomax (tamsulosin) is an alpha blocker medication used to treat the symptoms of benign prostatic hyperplasia (BPH or enlarged prostate). These symptoms include difficulty in beginning urination, weak stream and the need to urinate frequently or urgently. It does not shrink the prostate but relaxes the muscles in your prostate and bladder neck therefore making it easier for men to urinate. This BPH medication should not be used in women or children.

Always read the patient information and instructions carefully before using this medication.

  • Flomax CR should be taken orally and is typically taken once daily, thirty minutes after a meal. Try to take this medication at the same time, following the same meal each day.
  • Swallow this medication whole. Do not crush, chew or open the capsules.
  • Your tamsulosin dosage is based on your medical condition and response to treatment. Do not change or increase your dosage unless advised by a doctor.
  • If you do not take tamsulosin for several days, ask your doctor if you need to be restarted at a lower dose.
  • It can take four weeks for your symptoms to improve. Tell your doctor if your condition has not improved or worsened after this time.
