How soon can you repeat a course of antibiotics?

You can only repeat an antibiotic course if your doctor prescribes it again, usually if symptoms return or don't clear up, but repeating too soon (like within days or weeks) without medical advice risks antibiotic resistance and ineffective treatment, as the bacteria might not be fully gone or could be resistant; doctors carefully decide repeat courses, sometimes within 30 days for things like UTIs, but overuse is a major concern. Always finish your first course as directed and consult your doctor for any new or persistent infection.
