An antiemetic provides relief from nausea and vomiting, which are typically caused by motion sickness, pregnancy, stomach irritation, or side effects from certain drugs.


    Antiemetics are substances that can help manage nausea and vomiting. Nausea is the feeling of needing to vomit, and vomiting consists of two phases: retching (strong contraction of muscles of the abdomen and diaphragm) and expulsion (in which the contents of the stomach are forced out).[1] Nausea and vomiting are commonly induced by motion sickness, pregnancy, stomach irritation, or certain drugs such as opioids, chemotherapy, or anesthetics.

    Supplements that may have some antiemetic properties include ginger and peppermint. Over-the-counter drugs that have antiemetic effects include dramamine and Emetrol. There are also prescription antiemetics, which include ondansetron, scopolamine, and promethazine.
