Palonosetron Injection

Palonosetron injection is used to prevent nausea and vomiting that may occur within 24 hours after receiving cancer chemotherapy or surgery. It is also used to prevent delayed nausea and vomiting that may occur several days after receiving certain chemotherapy medications. Palonosetron injection is in a class of medications called 5-HT<span class='sub'>3</span> receptor antagonists. It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting.

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. If you are receiving more than one course of chemotherapy, you may receive a dose of palonosetron before each treatment cycle. When palonosetron is used to prevent nausea and vomiting caused by surgery, it is usually given as a single dose just before the surgery. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
