Emend is used for preventing nausea and vomiting in people who are about to undergo surgery or chemotherapy. While the drug cannot treat nausea and vomiting once it starts, it can help prevent it from occurring in the first place. Healthcare providers may also occasionally recommend "off-label" Emend uses, such as for the treatment of nausea and vomiting due to other causes.
Emend® (aprepitant) is a prescription medication approved for the prevention of nausea and vomiting due to chemotherapy or surgery.
Surgery is a common cause of nausea and vomiting. However, not all types of surgery are likely to cause nausea and vomiting. Surgeries involving the abdomen (stomach area), eye, ears, nose, and throat are most likely to cause nausea or vomiting. Certain people are at higher risk for postoperative nausea and vomiting, including the following people:
- People who get motion sickness
- People who have had nausea or vomiting after surgery in the past
- People who do not smoke
- People who will use certain morphine-like medications ("opioids") after surgery.
Your healthcare provider will take all of these factors into consideration when deciding whether you will need medication to prevent nausea and vomiting.
Emend is given before surgery to help prevent nausea and vomiting from occurring. It is not approved to treat nausea and vomiting after it starts, and it is much harder to treat nausea or vomiting than to prevent it from happening in the first place.
