Cyclizine is used to prevent or treat nausea, vomiting, and dizziness caused by motion sickness. It may also be used to reduce lightheadedness, dizziness, and loss of balance (vertigo) caused by diseases that affect the inner ear. This medication works on the area of the brain that controls nausea and vomiting and on the inner ear to decrease these symptoms. Cyclizine belongs to a class of drugs known as antihistamines.
