Zofran (Ondansetron) Buyer and Patient Handbook in South Africa

What is Zofran?

Zofran is an oral anti-nausea tablet that belongs to the serotonin 5-HT₃-receptor antagonist class and is used to prevent nausea and vomiting caused by chemotherapy, radiation therapy, and surgery. It is approved by the South African Health Products Regulatory Authority (SAHPRA) and is available as 4 mg and 8 mg tablets.

Who Should Use Zofran?

• Adults undergoing Cancer chemotherapy
• Patients receiving radiation therapy that affects the stomach or intestines
• Individuals scheduled for surgery who are at risk of post-operative nausea
• Anyone prescribed Zofran by a qualified health professional for the above indications

How Does It Work?

Zofran blocks serotonin receptors in the brain’s vomiting centre and in the gut, stopping the signal that normally triggers nausea and vomiting. Think of it as turning off the alarm that tells your brain “something is wrong” after a chemo session. It has a low potential for abuse and is not habit-forming.

Why Choose Zofran?

• Proven efficacy: Clinical trials consistently show rapid relief of nausea within 30 minutes.
• Convenient oral form: Easy to take at home without an injection.
• Available in two strengths: Allows your health professional to match the dose to the intensity of your treatment. Off-label uses exist (e.g., for severe morning sickness) but should only be considered after professional advice.
