Urine Flow
Men who took tamsulosin also had an improvement in the rate of urine flow. This increased flow rate was seen as early as the first week after starting BPH treatment with the medication and continued throughout the entire study.

When and How to Take Tamsulosin

Some general considerations for when and how to take tamsulosin include the following:
  • The medication comes in capsule form. It is taken by mouth once daily, 30 minutes after a meal.
  • The capsules should be taken whole and should not be opened, chewed, or crushed.
  • Tamsulosin should be taken at the same time each day to maintain an even level in your blood.
For the medication to work properly, it must be taken as prescribed. Tamsulosin will not work if you stop taking it.

Dosing Information

When first starting tamsulosin (or if you have been off the drug for several days), the dose is 0.4 mg once daily. If the medication does not seem to be working after two to four weeks at this dose, your healthcare provider may increase your dose to 0.8 mg once daily.
As with any medication, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Side Effects of Tamsulosin

As with any medicine, side effects are possible with tamsulosin. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it well. If side effects do occur, they are often minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
The most common side effects include:
  • Abnormal ejaculation (see Flomax Sexual Side Effects for more information)
  • Runny or stuffy nose
  • Dizziness
  • Infections, including the cold or flu.
