How Meclizine works
Meclizine is a first-generation antihistamine. It acts by blocking the H1 histamine receptors in the body. This means it prevents the effects of histamine, a substance that causes allergy symptoms. By blocking these receptors, it effectively reduces symptoms such as nausea, vomiting, and dizziness, which are often associated with motion sickness and vertigo.
