How is a urinary tract infection (UTI) treated?

To treat a urinary tract infection (UTI), your doctor will test a sample of your urine for bacteria and blood cells. Depending on the results, your doctor may prescribe an antibiotic medication. You may need to try different antibiotics to see which one works best against the bacteria.

UTIs treated with antibiotics often clear up after one or two days of treatment. However, your doctor may tell you to take the antibiotic for one or two weeks to make sure the infection has been cured. Your doctor also may suggest you take a pain reliever, use a heating pad and drink plenty of fluids.

A urinary tract infection is treated with antibiotics. In the past, an infection would be treated for ten days. More recently, the recommendations for a simple urinary tract infection are for treatment for three to five days depending on the antibiotic. There is a newer treatment that is a one-dose therapy but it is a bit pricey.

UTIs are treated with antibiotics (an-tuh-beye-OT-iks), medicines that kill the bacteria that cause the infection. Your doctor will tell you how long you need to take the medicine. Make sure you take all of your medicine, even if you feel better! Many women feel better in one or two days.

If you don't take medicine for a UTI, the UTI can hurt other parts of your body. Also, if you're pregnant and have signs of a UTI, see your doctor right away. A UTI could cause problems in your pregnancy, such as having your baby too early or getting high blood pressure. Also, UTIs in pregnant women are more likely to travel to the kidneys.
