Doctors prescribe phenazopyridine to relieve burning and pain caused by irritation in the urinary tract, according to WebMD. The medication may also relieve the need to urinate frequently or urgently.
Phenazopyridine treats the symptoms of urinary irritation, not its cause, notes WebMD. Doctors usually prescribe it alongside other medications used to treat urinary tract infections, such as antibiotics. The usual dose of the medicine for teenagers and adults is 200 milligrams by mouth three times daily, but individual dosing directions vary according to the condition the medicine treats and the patient, states Mayo Clinic.
Phenazopyridine comes in both 100- and 200-milligram tablets, according to RxList.
