Pyridium is used to treat urinary symptoms such as pain or burning, increased urination, and increased urge to urinate. These symptoms can be caused by infection, injury, surgery, catheter, or other conditions that irritate the bladder.
Pyridium will treat urinary symptoms, but this medication will not treat a urinary tract infection.. Take any antibiotic that your doctor prescribes to treat an infection.

To avoid stomach upset, take this medicine with food.
Pyridium will most likely darken the color of your urine to an orange or red color. This is a normal effect and is not cause for alarm unless you have other symptoms such as pale or yellowed skin, fever, stomach pain, nausea, and vomiting. Darkened urine may also cause stains to your underwear, which may or may not be removed by laundering.
