Understanding Setofilm® (Ondansetron)
Setofilm® is a prescription medication whose active ingredient is ondansetron. It belongs to a class of drugs known as serotonin 5-HT3 receptor antagonists. Its primary function is to prevent and treat nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery. The medication works by blocking the action of serotonin, a natural substance in the body that can trigger nausea and vomiting. Setofilm® is an orodispersible film (ODF), which is designed to dissolve on the tongue within 4 to 20 seconds without the need for water. This makes it a convenient option for patients who have difficulty swallowing tablets, such as children and the elderly.
Step-by-Step Guide: How to Use Setofilm®
Proper administration is crucial for the medication's effectiveness. Always follow the directions given by your doctor or pharmacist.
- Ensure Hands are Dry: Before handling the film, make sure your hands are clean and completely dry.
- Open the Sachet: Keep the film in its foil pouch until you are ready to use it. Open the sachet carefully at the tear notch. Do not cut the sachet, as this could damage the film.
- Remove the Film: Gently remove the film from the pouch. Check that the film is intact before use; do not use a damaged film.
- Place on Tongue: Make sure your mouth is empty. Immediately place the film on top of your tongue.
- Let it Dissolve: The film will dissolve in your mouth within seconds. Do not chew or swallow the film whole.
- Swallow: After the film has dissolved, you can swallow with your saliva. You may drink liquid to help swallow the dissolved medication if desired, but it is not necessary.
- Multiple Films: If your prescribed dose requires more than one film, allow the first film to dissolve completely before placing the next one on your tongue.
- Wash Hands: Wash your hands after using the medication.
Dosage and Administration
Dosage of Setofilm® varies depending on the patient's age, medical condition, and the reason for treatment. It's essential to take it exactly as prescribed by your doctor. Your healthcare provider will determine the appropriate dose for your specific situation.
- For Chemotherapy-Induced Nausea: Dosage and frequency are determined by the doctor based on factors such as the emetogenic potential of the chemotherapy regimen.
- For Post-Operative Nausea: Dosage and timing are determined by the doctor, typically administered before anesthesia.
- For Children: Dosage is determined by the doctor based on the child's weight or body surface area.
- Patients with Liver Impairment: Patients with moderate to severe liver problems may require a lower total daily dose, as determined by a healthcare provider.
Setofilm® vs. Ondansetron Tablets
Setofilm® contains the same active ingredient as ondansetron tablets and has been shown to be equivalent in effectiveness. The primary difference lies in the delivery method.

Potential Side Effects and Precautions
Like all medications, Setofilm® can cause side effects. Common side effects include headache, constipation, weakness, tiredness, and dizziness.
You should not use Setofilm® if you are taking apomorphine (used to treat Parkinson's disease) or if you are allergic to ondansetron or other 5-HT3 receptor antagonists.
Before taking Setofilm®, inform your doctor if you have:
- Heart problems, including an irregular heartbeat or a family history of Long QT syndrome.
- Liver disease.
- A blockage in your gut or severe constipation.
- Low levels of potassium or magnesium in your blood.
Seek immediate medical attention if you experience serious side effects such as blurred vision, chest pain, difficulty breathing, severe dizziness, or signs of serotonin syndrome (agitation, hallucinations, fever, fast heart rate).

Setofilm® offers an effective and convenient alternative to traditional tablets for managing nausea and vomiting. Its orodispersible film technology is particularly beneficial for patients who struggle with swallowing pills.
