Antiemetic

An antiemetic is a medication used to treat nausea and vomiting. It works by blocking the action of certain chemicals in the brain and the body that cause vomiting. It also increases muscle contractions in the stomach and intestines, which can help reduce nausea. There are different types of antiemetics available, including prescription, over-the-counter, and natural remedies. Common prescription antiemetics include promethazine, ondansetron, and metoclopramide. Over-the-counter antiemetics include ginger, vitamin B6, and peppermint. Natural remedies include chamomile tea, acupuncture, and acupressure. Antiemetics are often used to control nausea and vomiting associated with chemotherapy, radiation therapy, and surgery. They are also used to treat motion sickness, food poisoning, morning sickness, and pregnancy-related nausea.
