Fosaprepitant 150 mg powder for solution for – patient leaflet, side effects, dosage

1. What Fosaprepitant infusion is and what it is used for

Fosaprepitant infusion contains the active substance fosaprepitant which is converted to aprepitant in your body. It belongs to a group of medicines called "neurokinin 1 (NK1) receptor antagonists". The brain has a specific area that controls nausea and vomiting. Fosaprepitant infusion works by blocking signals to that area, thereby reducing nausea and vomiting. Fosaprepitant infusion is used in adults, adolescents, and children aged 6 months or older in combination with other medicines to prevent nausea and vomiting caused by chemotherapy (cancer treatment) that is a strong or moderate trigger of nausea and vomiting.

• with medicines containing pimozide (used to treat psychiatric illnesses), terfenadine and astemizole (used for hay fever and other allergic conditions), cisapride (used for treating digestive problems).

The powder is reconstituted and diluted before use. The solution for infusion is given to you by a health care professional, such as a doctor or nurse, via an intravenous infusion (a drip) approximately 30 minutes before you start the chemotherapy treatment in adults or 60 – 90 minutes before you start the chemotherapy treatment in children and adolescents. Your doctor may ask you to take other medicines including a corticosteroid (such as dexamethasone) and a ‘5HT3 antagonist’ (such as ondansetron) for preventing nausea and vomiting. Check with your doctor or pharmacist if you are not sure.
