Patient Education

Methenamine


Methenamine, an antibiotic, eliminates bacteria that cause urinary tract infections. It usually is used on a long-term basis to treat chronic infections and to prevent recurrence of infections. Antibiotics will not work for colds, flu, or other viral infections. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Sodium Phosphate


Sodium phosphate is used in adults 18 years of age or older to empty the colon (large intestine, bowel) before a colonoscopy (examination of the inside of the colon to check for colon cancer and other abnormalities) so that the doctor will have a clear view of the walls of the colon. Sodium phosphate is in a class of medications called saline laxatives. It works by causing diarrhea so that the stool can be emptied from the colon.
