How long should I take antibiotics for a urinary tract infection (UTI)?

ANSWER

Your doctor will let you know. Typically, for an uncomplicated infection, you'll take antibiotics for 2 to 3 days. Some people will need to take these medicines for up to 7 to 10 days. For a complicated infection, you might need to take antibiotics for 14 days or more.

If you get UTIs often, you may need to take low-dose antibiotics every day for 6 months or longer -- and if sex causes your UTIs, you'll take a dose of the medicine right before you have sex.
