What is Ondansetron?

Ondansetron is a selective serotonin 5-HT3 receptor antagonist that is primarily used to prevent nausea and vomiting caused by chemotherapy, radiation therapy, and post-operative recovery. By blocking the action of serotonin in the brain and gut, Ondansetron helps minimize those uncomfortable feelings that can often accompany medical treatments.

Key Uses of Ondansetron

• Chemotherapy-Induced Nausea: Given before chemotherapy treatments to help reduce nausea.
• Post-operative Nausea: Administered after surgeries to decrease the risk of vomiting.
• Radiation Therapy: Used prior to sessions to alleviate potential nausea.

Ondansetron comes in various forms, including:

Common Mistakes to Avoid

1. Inadequate Timing: Not administering it in advance of treatments can lead to poor outcomes. ⏰
2. Overdosage: Always follow prescribed dosages; taking more can increase the risk of side effects.
