Meclizine, an antihistamine commonly used to treat motion sickness, vertigo, and dizziness, is a popular medication among travelers and individuals suffering from balance disorders. While it can provide relief from these conditions, meclizine can also cause a range of side effects, some of which can be severe. In this article, we will delve into the world of meclizine side effects, exploring the common, rare, and serious adverse reactions associated with this medication.
Meclizine's mechanism of action is not fully understood, but it is believed to work by blocking the action of histamine, a neurotransmitter involved in the regulation of balance and equilibrium. This blockade can lead to a range of effects, including drowsiness, dry mouth, and blurred vision. While these side effects are generally mild and temporary, they can be bothersome and, in some cases, severe.

- Drowsiness and fatigue
- Dry mouth
- Blurred vision
- Headache
- Dizziness
- Nausea and vomiting
- Constipation
These side effects are usually dose-dependent, meaning that higher doses of meclizine are more likely to cause adverse reactions. However, individual tolerance to the medication can vary greatly, and some people may experience side effects at lower doses.
