Nausea is a state that precedes vomiting and it may occur for many reasons. Common causes of nausea include motion sickness, certain illnesses that last a few days, and toxins (including certain medicines).

You should consult with a doctor if your nausea or vomiting persist and cause other symptoms such as fever, abdominal pain, jaundice, or bleeding.

Nausea associated with motion sickness may occur in settings including travel by car, or any other transport. OTC medications for nausea, like Antivert (meclizine), treat nausea associated with motion sickness.
