Common Questions about Flomax (tamsulosin)


Does Flomax make you pee more?

Flomax relaxes the muscles of the prostate and bladder to improve urination. This can increase the flow of urine and make you feel like you are peeing more.



What is the best time of day to take Flomax?

Take your Flomax 30 minutes after breakfast, if you can. This can make it easier to urinate throughout the day. You can also take the capsule 30 minutes after lunch or dinner. Take your medicine at around the same time every day.



Why do you have to wait 30 minutes after you eat to take Flomax?

Taking Flomax on an empty stomach allows more of the medication to be absorbed quickly. However, this can cause more side effects, such as a drop in blood pressure when you stand up from sitting or lying.



How long does it take for Flomax to start working?
