Should I rinse my mouth after using nystatin?
If you are using nystatin oral suspension, do not rinse mouth after use. Keep the suspension in the mouth as long as possible before spitting or swallowing, as directed by your doctor. Should I brush my teeth after using nystatin? Since nystatin liquid contains sugars, it is best to brush your teeth after using it, especially if it's before bed. You should wait about 30 minutes after taking nystatin to brush your teeth to give the medication enough time to work.
