How many days of antibiotics cure a UTI?
Most uncomplicated UTIs in women are treated with antibiotics for 3 to 7 days, depending on the drug used and the infection’s severity. Always complete the full course prescribed.
Detailed Medical Explanation
The recommended duration for antibiotics varies: nitrofurantoin is usually 3 days, trimethoprim 3–7 days, and others (like amoxicillin or cefalexin) up to 7 days for lower UTIs. Longer treatment may be required for complicated infections or in men, pregnant women, or people with kidney involvement. NICE BNF: Antibiotic duration for UTI.
Clinical Context
Clinics ensure you receive the correct length of treatment for your specific situation. Do not stop antibiotics early, even if you feel better.
Evidence-Based Approaches
NHS and NICE base UTI antibiotic duration on research and individual patient risk factors. Follow the course given by your healthcare provider.
