There is no clear agreement on specific medication, but the selection of antiemetic drugs such as promethazine, metoclopramide and ondansetron are the most common in the United States, may vary from person to person depending on how nauseous they are. For those suffering from motion sickness, antihistamines and anticholinergics such as meclizine and scopolamine are especially effective. Nausea and vomiting associated with migraines are more responsive to dopamine antagonists such as metoclopramide, prochlorperazine and chlorpromazine.

In case of pregnancy nausea, an association of pyridoxine and doxylamine is prescribed.
