Pyridium Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Pyridium (phenazopyridine hydrochloride) is used to treat pain, burning, increased urination, and increased urge to urinate. These symptoms are usually caused by infection, injury, surgery, catheter, or other conditions that irritate the lower urinary tract. It treats the symptoms of a urinary tract infection, but does not treat the actual infection. Pyridium is an analgesic pain reliever. This medication is available in generic form. Common side effects include headache, dizziness, or stomach upset.
The adult dosage of Pyridium is two 200 mg tablets 3 times a day after meals. Other drugs may interact with Pyridium. Tell your doctor all prescription and over-the-counter medications and supplements you use. During pregnancy, Pyridium should be used only if prescribed. It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.
