Zofran (Ondansetron) is a medication used to prevent and treat nausea and vomiting caused by cancer chemotherapy, radiation therapy, or surgery. It works by blocking the action of serotonin, a natural substance in the body that can trigger nausea and vomiting. Zofran is highly effective and commonly used in hospitals and outpatient settings for patients undergoing treatment for cancer, recovering from operations, or dealing with severe stomach upset due to other causes. Its rapid onset and safety profile make it a preferred option for nausea control.
Zofran is typically taken by mouth, with or without food, and may also be administered as an injection in clinical settings. The dosage varies depending on the cause of the nausea, patient age, and medical condition. For chemotherapy-induced nausea, the usual adult dose is 8 mg before treatment, followed by 8 mg every 8 or 12 hours. Always follow your healthcare provider’s exact instructions. Do not increase your dose or take it more often than prescribed. Take it with a full glass of water and at consistent times for best results.
Before using Zofran, inform your doctor of any personal or family history of heart rhythm problems, liver disease, or electrolyte imbalances such as low potassium or magnesium. Zofran can affect the heart's rhythm (QT prolongation), so it should be used cautiously in those with underlying cardiac issues. Avoid driving or operating machinery if the medication makes you dizzy or sleepy. Let your doctor know if you are pregnant, planning pregnancy, or breastfeeding.
Zofran should not be used by individuals allergic to Ondansetron or similar medications such as Granisetron. It is contraindicated in patients taking Apomorphine due to the risk of severe low blood pressure and loss of consciousness. Caution is advised in individuals with congenital long QT syndrome or those on medications that can affect heart rhythm. Discuss your full medical and medication history with your doctor before starting Zofran.
Common side effects of Zofran include headache, constipation, dizziness, and fatigue. These effects are usually mild and temporary. Serious but rare side effects may include irregular heartbeat, fainting, vision changes, or severe allergic reactions (rash, itching, swelling, trouble breathing). Seek immediate medical help if any of these occur. Inform your doctor if side effects persist or worsen. Routine monitoring may be needed in long-term use or high doses.
Zofran may interact with other medications that affect heart rhythm, such as certain antiarrhythmics, antipsychotics, or antibiotics. It may also interact with seizure drugs, antidepressants, or medications that increase serotonin levels. Combining Zofran with serotonergic drugs can raise the risk of serotonin syndrome, a potentially serious condition. Always provide a full list of your current medications to your healthcare provider to avoid dangerous interactions.
If you miss a dose of Zofran, take it as soon as possible. If it is close to your next scheduled dose, skip the missed one and continue with your regular schedule. Do not double the dose. Consistent dosing is important for preventing nausea effectively, especially around chemotherapy or surgery. If multiple doses are missed or symptoms worsen, consult your healthcare provider for guidance.
Overdose symptoms may include sudden vision loss, severe constipation, fainting, or irregular heartbeat. If you suspect an overdose, seek emergency medical attention right away. Provide medical personnel with complete information on the amount taken and the timing of the overdose. Prompt treatment can prevent serious complications and ensure patient safety.
Store Zofran tablets at room temperature between 15°C and 30°C (59°F and 86°F). Keep the medication in a tightly closed container away from moisture, heat, and direct sunlight. Do not store in the bathroom. Keep out of reach of children and pets. Do not use expired medication. Properly dispose of unused or expired drugs following local guidelines or your pharmacist’s instructions.
