Meclizine is an antihistamine agent with antiemetic and antispasmodic properties.Antihistamines work by reducing the effect of histamine, a chemical generated in the body as a response to an allergic reaction, and interfere with histamine effects such as narrowing of airways, vasodilation and heightened permeability of blood vessels.
Meclizine suppresses the central nervous system by its anticholinergic effect on neurotransmitter Acetylcholine.
Meclizine hydrochloride was found to be a good suppressor of vestibular stimulation by controlling the activity of hair cells in the inner ear and therefore helpful in treating vertigo symptoms like dizziness and spinning.
Since the drug reduces central brain activity, it reduces nausea and vomiting sensation and is used for control of motion sickness as an antiemetic agent.
The drug helps in muscle relaxation too due to its antispasmodic property.

Meclizine and Vestibular Disorder
As mentioned earlier in the post, Meclizine Hydrochloride acts by reducing the activity and sedating the central nervous system to reduce the vestibular stimulation. This action helps control the acute vertigo symptoms like spinning sensation and nausea.
The drug is suitable for vertigo patients who are facing acute vertigo symptoms. The drug should not be taken for more than 5 days. Continual use of the drug will interfere with compensation of the central nervous system leading to a reduced or incomplete recovery. Instead, central compensatory treatment like vestibular rehabilitation therapy and physical manoeuvres help provide cure to the vertigo issue. This treatment provides sustained results in reducing vertigo symptoms and improves the treatment outcome.
Meclizine does not address lightheadedness, unsteadiness, and imbalance. This drug is suggested mainly to vertigo patients with vestibular disorders like Meniere’s Disease, Labyrinthitis, vestibular neuritis in the acute stage. Meclizine should be stopped as soon as possible once the acute symptoms subside.
