What is Nulytely?
Nulytely is a prescription medicine adults use to clean the colon before a colonoscopy. Nulytely cleans your colon by causing you to have diarrhea. Cleaning your colon helps your healthcare provider see the inside of your colon more clearly during your colonoscopy.
Nulytely is safe and effective for use in patients aged 6 months and older.
