Side effects

Common side effects of FLOMAX are:

  • runny nose
  • dizziness
  • decrease in semen

Avoid driving or hazardous tasks for 12 hours after your first dose or increase in dose, as a sudden drop in blood pressure may occur, rarely resulting in fainting. If considering cataract surgery, tell your eye surgeon you’ve taken FLOMAX. Only your doctor can tell if you have BPH, not a more serious condition like prostate cancer.

Can I take FLOMAX while I'm using other medications?

FLOMAX can be taken with these common antihypertensive (high blood pressure) and cardiovascular (heart disease) medications without dosage adjustment:

  • atenolol
  • enalapril
  • nifedipine

However, there are some medications that should be used with caution when taking FLOMAX, such as:

  • warfarin (a blood-thinning medication also known as Coumadin®)
  • cimetidine (a medication that treats ulcers)

Always tell your doctor what prescription and over-the-counter drugs, vitamins and/or dietary supplements you are taking. This is important so that your doctor can avoid prescribing medications that may negatively interact with each other.
