How long does it take for Flomax to be effective?

A: Most people notice symptoms of BPH starting to improve within a week of taking tamsulosin. This is the time it takes for the drug to build up in your body to a level that works. If urinating doesn't get easier for you or you don't have fewer urges to urinate within 2 weeks after starting this drug, tell your doctor.

What are the long term effects of taking tamsulosin?

Similar to other alpha blockers, Flomax side effects may include:
  • Postural hypotension (low blood pressure when changing position, such as rising from a seated or lying position)
  • Dizziness.
  • Vertigo.
  • Fatigue.
  • Fainting.
  • Headache.
  • Nasal congestion.
  • Painful, prolonged erection that last four hours or more.
