Kytril injection is an intravenous solution made up of a 5HT3 receptor antagonists drug called granisetron. We carry the brand choice of this medication in in 1mg/ml!

The Kytril injection is most commonly used in cancer patients to prevent nausea and vomiting caused by chemotherapy (a drug treatment) or radiation therapy. Chemotherapy and radiation therapy are methods of killing cancer cells, however, they also kill healthy cells in the process. The affected cells are usually located in the protective lining of the mouth and digestive tract which then causes irritation leading to symptoms of nausea and vomiting.

The Kytril injection is used to prevent symptoms of nausea and vomiting and is effective due to its ability to block the serotonin in the body that triggers vomiting.

If you are injecting this medication yourself; ensure you have read all instructions on how to properly inject the medicine into a vein. If you are unsure, consult your doctor or have a doctor assist with the injection.

Inject this medication in to vein 30 minutes before the cancer treatment. Alternatively, you may mix the solution into IV fluid and given into a vein over a period of 5 minutes.
