Meclizine is an over-the-counter (OTC) medication commonly used to treat dizziness, vertigo, and motion sickness. As with any medication, it's essential to be aware of the potential side effects of meclizine OTC. In this article, we'll explore the common and less common side effects of meclizine, as well as provide guidance on how to use the medication safely and effectively.
Meclizine belongs to a class of medications known as antihistamines, which work by blocking the action of histamine in the body. Histamine is a chemical that can cause blood vessels to dilate, leading to increased blood flow and symptoms such as dizziness and nausea. By blocking histamine, meclizine helps to alleviate these symptoms and provide relief for individuals experiencing motion sickness or vertigo.
