Phenazopyridine — Uses, Dosage, Side Effects & Safety

Drug class: Urinary tract analgesic

Overview

Phenazopyridine is a medication used to relieve pain, burning, urgency, and discomfort caused by irritation of the lower urinary tract, such as that from urinary tract infections (UTIs), surgery, or injury. It does not treat the underlying infection but helps make urination more comfortable while other treatments, such as antibiotics, address the cause. Phenazopyridine works by exerting a local analgesic effect on the lining of the urinary tract. It helps to reduce the sensation of pain and burning during urination. Patients should be aware that this medication can cause a reddish-orange discoloration of urine, which is harmless but may stain clothing or contact lenses. It is important to use phenazopyridine only for short-term symptom relief and not as a substitute for medical treatment of infections. Always follow your healthcare provider's instructions and complete any prescribed antibiotics.
