Uses for Uretron D/S

Urelle® contains five medicines: hyoscyamine, methenamine, methylene blue, phenyl salicylate, and sodium phosphate. It helps relieve discomfort, swelling, pain, frequent urges to urinate, and cramps or spasms in the urinary tract caused by an infection or a diagnostic procedure.

Hyoscyamine is an antispasmodic that eases muscle cramps or spasms. Methenamine and methylene blue are antiseptics that help treat a urinary tract infection. Phenyl salicylate is a pain reliever. Sodium phosphate makes the urine more acidic, which helps methenamine work more effectively.

You can only get this medicine with a prescription from your doctor.

Precautions while using Uretron D/S

It is very important that your doctor checks the progress of you or your child at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.

If your or your child's symptoms do not improve or if they get worse, call your doctor.

Stop using this medicine and check with your doctor right away if you or your child have blurred vision, dizziness, or rapid pulse.

This medicine will make your urine colored blue. This is normal and is nothing to worry about.

This medicine will not cure a serious urinary tract infection and will only work to relieve symptoms as long as you continue to take it.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
