What is the Fastest Way to Get Rid of a UTI?

The fastest way to treat a UTI is with prescription antibiotics, which typically clear symptoms within 1-3 days. Uncomplicated UTIs usually respond to a 3-day course of antibiotics like nitrofurantoin or trimethoprim-sulfamethoxazole. While you're waiting for medical care, drink plenty of water to help flush bacteria from your system and consider over-the-counter pain relievers for discomfort. Avoid delaying treatment, as untreated UTIs can progress to serious kidney infections within days. Home remedies like cranberry juice may provide minor relief but cannot cure an active infection—only antibiotics can eliminate the bacterial cause.
