Onseron Syrup 50 Ml – Nausea & Vomiting Relief
Description
Onseron Syrup 50 ml – Ondansetron Oral Liquid for Nausea and Vomiting Relief
Onseron Syrup 50 ml contains Ondansetron, a selective serotonin (5-HT3) receptor antagonist that prevents nausea and vomiting associated with cytotoxic chemotherapy, radiotherapy, and surgical procedures. Ondansetron selectively blocks 5-HT3 receptors in both the central nervous system and the peripheral gastrointestinal tract, preventing serotonin — released from enterochromaffin cells during treatment — from triggering the vomiting reflex.
The 50 ml pack provides a larger supply for patients on extended treatment courses. Its liquid form is ideal for children and adults who cannot swallow tablets, offering the same clinical efficacy in a convenient oral formulation. Prescription required. Use under medical supervision.
