🔔 How should this medicine be used?

Palonosetron injection comes as a solution (liquid) to be injected intravenously (into a vein) by a healthcare provider in a hospital or clinic. When palonosetron is used to prevent nausea and vomiting caused by chemotherapy, it is usually given as a single dose about 30 minutes before the start of chemotherapy.
