Flomax

Why should Flomax not be prescribed?

If Flomax gives you an allergic reaction, you cannot take the drug.

Special warnings about Flomax

Remember that, in a few men, Flomax can cause a drop in blood pressure upon first standing up, which in turn can lead to dizziness or fainting. Avoid driving and other hazardous tasks for 12 hours after your first dose or a dosage increase, and be careful to stand up slowly until you're sure the drug won't make you dizzy. If you do become dizzy, sit down until it passes.

Although the problem is extremely rare (affecting perhaps 1 in 50,000) Flomax has been known to cause priapism--a painful, persistent erection unrelated to sexual activity. If you develop this side effect, call your doctor without delay. The condition can lead to permanent impotence if not treated immediately.

Possible food and drug interactions when taking Flomax

If Flomax is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Flomax with any of the following:

Blood pressure drugs classified as alpha-blockers, such as Catapres
Cimetidine (Tagamet)
Warfarin (Coumadin)

Special information if you are pregnant or breastfeeding

Flomax is for use only by men.
