Product Information:
ONSEGET 8mg Tablets contain Ondansetron 8mg, a selective 5-HT₃ receptor antagonist used to prevent and treat nausea and vomiting. It works by blocking serotonin receptors in the gut and brain (chemoreceptor trigger zone), making it highly effective against chemotherapy-induced, radiotherapy-induced, and postoperative nausea and vomiting.
This strength is commonly used for moderate to severe emetogenic triggers in adults.
