Nystatin Side Effects

Side Effects to Report

There are a few possible (though unlikely) side effects with nystatin that you should report to your healthcare provider. These include, but are not limited to:
  • Bloody or very severe diarrhea
  • A rapid heart rate (tachycardia)
  • Unexplained peeling of the skin
  • Signs of an allergic reaction, such as:
    • An unexplained rash
    • Hives
    • Itching
    • Unexplained swelling (especially of the lips, mouth, or throat)
    • Wheezing or other breathing problems.

Final Thoughts

It is possible that you may experience some or none of the nystatin side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried.
Therefore, make sure to let your healthcare provider know if you develop any side effects while taking nystatin. Also, let your healthcare provider know if you develop something that "just does not seem right." While it may not be a nystatin side effect, your healthcare provider will be able to diagnose and treat the problem.
