Why is this medication prescribed?
Rolapitant injection is used along with other medications to prevent nausea and vomiting that may occur several days after receiving certain chemotherapy medications. Rolapitant is in a class of medications called antiemetics. It works by blocking the action of neurokinin and substance P, natural substances in the brain that cause nausea and vomiting.
How should this medicine be used?
Rolapitant injection comes as a solution (liquid) to be injected intravenously (into a vein) by a healthcare provider in a hospital or clinic. It is usually infused intravenously as a single dose over a period of 30 minutes within 2 hours before the start of chemotherapy.
Rolapitant injection may cause serious reactions during the infusion of the medication, often during the first few minutes. A doctor or nurse will monitor you carefully while you are receiving the medication. If you experience any of the following symptoms, tell your doctor immediately: hives; rash; flushing; itching; difficulty breathing or swallowing; shortness of breath; swelling of the eyes, face, mouth, tongue, or throat; chest pain; stomach pain or cramping; vomiting; dizziness; or fainting.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
