Ondansetron Tablets For Anti-Sickness (4mg, 8mg)

Ondansetron tablets are an anti-sickness (antiemetic) medication used to prevent and treat nausea and vomiting caused by chemotherapy, radiotherapy, surgery, or certain medical conditions. They work by blocking serotonin (5-HT3) receptors in the brain and gut, which play a key role in triggering the vomiting reflex. This helps reduce feelings of sickness and prevents vomiting episodes.

Ondansetron is usually taken shortly before treatment or as directed by a healthcare professional, and may be used short-term or for a few days depending on the cause. It is generally well tolerated and does not cause drowsiness in most people.
