How To Use Tamsulosin (Flomax)

Take the tamsulosin capsule by mouth once daily, 30 minutes after the same meal each day. Swallow the capsule whole. Do not cut, crush, or chew it.

Read the prescription label and package insert carefully. Take tamsulosin exactly as prescribed by your healthcare provider. Do not change the dose or dosing frequency without your doctor’s approval.

Your doctor will start you on tamsulosin 0.4 mg daily. They may increase the dose to 0.8 mg daily, if needed, after 2-4 weeks.

Tamsulosin can control lower urinary tract symptoms related to benign prostatic hyperplasia (BPH) as long as you continue taking the medicine. It will not, however, shrink the prostate gland or cure your BPH. Continue tamsulosin therapy even if your symptoms are well controlled. Do not discontinue treatment without consulting your healthcare provider.

Missed dose: If you miss a dose of tamsulosin, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and take the next dose according to your regular dosing schedule. Do not take double or extra doses to make up for a missed dose. If you miss several days of your tamsulosin dose, call your healthcare provider, especially if you are on a higher dose (0.8 mg daily). You may need to restart tamsulosin at a lower dose again (0.4 mg daily).

Storage: Store tamsulosin at room temperature (between 15-30° C or 59-86° F) away from moisture, heat, and direct light in its original container, tightly closed. Do not store medications in the bathroom where they can be exposed to moisture and heat. Keep all medications safely out of reach of children and pets.

Unused medicine: Unused or expired tamsulosin should be disposed of in a way that children, other people, and pets cannot get to them. Do not throw tamsulosin in the trash or flush it down the toilet. The best way to dispose of expired or unneeded tamsulosin is through a drug take-back program. Learn more about proper medication disposal.
