What should I discuss with my healthcare provider before taking nystatin?
Stop taking nystatin and seek emergency medical attention if you experience an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives). Side effects are not likely to occur with nystatin. Continue to take nystatin and talk to your doctor if you experience • nausea or stomach upset, • vomiting, or • diarrhea. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.
