What special precautions should I follow?
While Zofran is generally considered safe for most people, there are some precautions and considerations to keep in mind:
- Allergies: Inform your healthcare provider about any known allergies to ondansetron or other medications.
- Medication Interactions: Provide a complete list of all medications, supplements, and herbal products you are taking to avoid potential interactions.
