Granisetron 3mg/3mL (1mg/mL) Injection

Product Introduction

Granisetron 3mg/3mL (1mg/mL) is a serotonin-receptor antagonist used to prevent or treat nausea and vomiting associated with chemotherapy and selected perioperative settings. It blocks a vomiting pathway activated by treatment-related serotonin release.

How to use

It is administered slowly into a vein or as a diluted infusion, usually before the treatment likely to cause vomiting. Timing and repeat doses depend on the chemotherapy or surgical antiemetic regimen.

How it works

Granisetron blocks 5-HT3 receptors in the gut and central nervous system, interrupting serotonin signals that trigger nausea and vomiting.

Side effects

Headache and constipation are common. Heart-rhythm changes, severe allergy and serotonin syndrome are uncommon but important.
