Pyridium (Phenazopyridine) is a medication used to alleviate the pain, burning, and discomfort associated with urinary tract infections. It provides relief of symptoms, but it does not treat the infection itself. It is available over-the-counter in the United States from our online store, with fast and reliable shipping. Pyridium works quickly to reduce pain, and its effects can last up to 24 hours. It is recommended that you drink plenty of water while taking this medication to help flush the infection from your system.
