An antiemetic is a drug that is effective against<unk>  and nausea. Antiemetics are typically used to treat motion sickness and the side effects of medications such as opioids and chemotherapy. Antiemetics act by inhibiting the receptor sites associated with emesis. Hence, anticholinergics, antihistamines, dopamine antagonists, serotonin antagonists, and cannabinoids are used as antiemetics. Evidence to support the use of antiemetics for nausea and<unk>  among adults in the emergency department is poor. It is unclear if any medication is better than another or better than no active treatment.
