Zofran, also known as ondansetron, is a widely prescribed medication used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery. As a selective serotonin 5-HT3 receptor antagonist, Zofran works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. With its effectiveness in managing these symptoms, it's essential to understand how to take Zofran safely and effectively to maximize its benefits while minimizing potential side effects.
According to the National Cancer Institute, approximately 70% of patients undergoing chemotherapy experience nausea and vomiting. In such cases, Zofran is often prescribed as a first-line treatment. However, to ensure safe and effective use, patients must be aware of the proper dosage, potential interactions, and necessary precautions.
Understanding Zofran: Dosage and Administration
The dosage of Zofran varies depending on the individual's age, medical condition, and response to treatment. For adults, the typical dose is 8 mg, taken 30 minutes before chemotherapy or radiation therapy, and then repeated 4 hours later. For children, the dosage is based on their weight, and the medication is usually administered 30 minutes before chemotherapy.
| Dosage Form | Adult Dosage | Children's Dosage |

| Oral | 8 mg, 30 minutes before chemotherapy or radiation therapy | Based on weight, 30 minutes before chemotherapy |
