What is Meclizine?
Meclizine is an antihistamine medication commonly prescribed to prevent and treat nausea, dizziness, vomiting, and vertigo caused by motion sickness or inner ear problems.
It works by reducing activity in the brain areas responsible for balance and nausea control, helping patients feel more stable and less dizzy.
