Some of these rare ondansetron side effects include, but are not limited to:
- Shakiness, tremors, or unusually stiff muscles
- Increased liver enzymes (found using a blood test)
- Increased heart rate (tachycardia)
- Chest pain
- Changes in heart rhythm (especially an arrhythmia called QT prolongation)
- Flushing (redness of the skin, especially the face)
- Hiccups
- Spasms of muscles of the eye, causing the eyes to become fixed in a certain position, often staring upward
- Temporary blindness.
Ondansetron Side Effects: Summary
You may experience some or none of the ondansetron side effects explained above. 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, be sure to let your healthcare provider know if you develop any side effects. Also, let you healthcare provider know if you develop something that "just does not seem right." While it may not be an ondansetron side effect, your healthcare provider will be able to diagnose and treat the problem.
