Common questions about Fosaprepitant (Emend)
Fosaprepitant (Emend) is used along with other anti-nausea medications to prevent nausea or vomiting caused by certain chemotherapy medications. But it can't be used to treat nausea or vomiting if you're already feeling nauseous.
Fosaprepitant (Emend) is an antiemetic. It helps to prevent nausea and vomiting by blocking a chemical in the brain called substance P, which controls your vomiting reflex.
For adults, the typical dose of fosaprepitant (Emend) is 150 mg infused through the veins (IV) by a healthcare provider. It's given about 30 minutes before the start of your chemotherapy on the first day of chemotherapy treatment. For children, the dose of fosaprepitant (Emend) depends on their age and body weight, and which chemotherapy treatment your child is receiving. Your child's provider will make sure your child gets the correct dose at the right time.
In clinical trials, the most common side effects people reported are feeling extremely tired and diarrhea, followed by low red and white blood cells, weakness, and tingling in the arms or legs. Please note that in the trials, people also received two other anti-nausea medications, dexamethasone and ondansetron (Zofran), so it's hard to know if these side effects are due to fosaprepitant (Emend) alone. As with any IV infusions, fosaprepitant (Emend) can also cause infusion site reactions, including redness, swelling, and pain.
Fosaprepitant (Emend) can interact with many different medications, including common ones like warfarin (Coumadin) and certain birth control medications. For example, fosaprepitant (Emend) can cause birth control medications that contain hormones to not work as well, which can raise your risk for getting pregnant. If you're using this type of birth control, you'll need to use a back up birth control method, such as condoms, both during treatment and for about a month after your last dose of fosaprepitant (Emend). Another example is that fosaprepitant (Emend) can cause warfarin (Coumadin) to not work as well, which can put you at risk for blood clots. If you're taking warfarin (Coumadin), your provider might need to monitor your labs more closely. Tell your provider all of the over-the-counter and prescription medications you're taking, as well as supplements, so they can let you know if there are any interactions with fosaprepitant (Emend).
