What Is Ondansetron?
Ondansetron is a 5-HT3 receptor antagonist anti-sickness medicine (antiemetic) used to prevent nausea and vomiting caused by chemotherapy, radiotherapy, or surgery. It is the generic equivalent of Zofran and contains the same active ingredient and strength. It works by blocking serotonin (5-HT3) receptors in the gut and brain that trigger the vomiting reflex.
Key Benefits
- Up to 80% cheaper than branded equivalents
- Same active ingredient, strength, and therapeutic effect
- Manufactured to WHO and international quality standards
- Discreet packaging and fast worldwide shipping
- No hidden fees – the price you see is the price you pay
How to Take Ondansetron
Take Ondansetron as directed, usually shortly before treatment likely to cause sickness and then at set intervals. Orally disintegrating tablets should be placed on the tongue to dissolve and then swallowed with saliva, without water. Do not exceed the prescribed dose.
Possible Side Effects
Common side effects include headache, constipation, tiredness, and dizziness. Seek immediate medical attention if you notice an irregular or fast heartbeat, fainting, or signs of a severe allergic reaction, as Ondansetron can occasionally affect heart rhythm (QT prolongation), particularly at higher doses or with certain other medicines.
Precautions
- Inform your doctor of all other medications you are taking to avoid interactions
- Tell your doctor about any allergies or existing medical conditions
- Keep out of the reach of children
- Store in a cool, dry place away from direct sunlight
