This medication is used to relieve symptoms caused by irritation of the urinary tract such as pain, burning, the feeling of needing to urinate urgently or frequently, and bladder spasms. This drug does not treat the cause of the urinary irritation, but it can help relieve the symptoms while other treatments take effect. This medication is a combination of three different drugs. Phenazopyridine is a dye that works as a painkiller to soothe the lining of the urinary tract. Hyoscyamine belongs to a class of drugs known as anticholinergics/antispasmodics. It works to decrease bladder spasms. Butabarbital is a sedative that helps to relieve the anxiety that can happen when you experience urinary pain and spasms.
Take this medication by mouth 4 times a day after meals and at bedtime or as directed by your doctor. If you are taking this medication along with antibiotics for symptoms related to a urinary tract infection, do not take it for more than 2 days without talking to your doctor.
