Description
Onset 4mg Injection
Onset 4mg Injection contains Ondansetron, a selective 5-HT3 (serotonin) receptor antagonist prescribed for the prevention and treatment of nausea and vomiting. It is widely used in clinical and hospital settings to manage nausea associated with post-operative recovery, chemotherapy, radiotherapy, and acute gastroenteritis.
Ondansetron works by blocking serotonin receptors in the gastrointestinal tract and in the chemoreceptor trigger zone (CTZ) of the brain — the key pathways that initiate the vomiting reflex. By suppressing these signals, Onset 4mg Injection provides rapid and effective antiemetic relief, allowing patients to recover more comfortably.
This injection is administered intravenously (IV) or intramuscularly (IM) by a qualified healthcare professional. The dose and frequency depend on the underlying cause, severity, patient weight, and clinical condition. Self-administration is not permitted. As with all Rx medicines, use only as prescribed by a doctor.
