What is how long does nitrofurantoin take to work on a uti?

  • Typical Onset: Nitrofurantoin typically starts working within a few hours to a day after starting treatment. You may begin to notice a reduction in your UTI symptoms such as pain or burning during urination, and the urge to urinate frequently.

  • Full Course Required: Even if you feel better, it is crucial to complete the entire prescribed course of nitrofurantoin as directed by your doctor. Stopping early can lead to the infection returning or becoming resistant to antibiotics.

  • Consult a Doctor: If your symptoms don't improve within a few days (e.g., 2-3 days) after starting nitrofurantoin, it is vital to contact your doctor. They may need to re-evaluate your condition and consider alternative treatment options.
