Vestibular Disorder and Meclizine

As already discussed in the post Meclizine Hydrochloride functions by reducing and sedating the activity of the brain’s central nervous system. It performs this action to offer control to acute vertigo symptoms such as nausea and spinning sensation.

People who are suffering from vertigo can consume this medicine. It is suitable for patients who experience acute vertigo symptoms. No matter what your condition is, the drug must not be consumed for more than 5 consecutive days. Overdosage of drug or continual consumption of drug will intervene with compensation and functionality of the central nervous system resulting in incomplete or reduced recovery. Rather, central compensatory cure like vestibular rehabilitation therapy as well as physical exercises and manoeuvers helps to offer a cure to the vertigo tissue. This treatment offers adequate and sustainable results to reduce vertigo symptoms and enhance the overall treatment outcome.

While Meclizine is great to reduce vertigo symptoms, the medicine might not be able to address other issues like unsteadiness, lightheadedness, and imbalance issues. It is suggested to consume drugs only by vertigo patients who are experiencing the problem due to disorders like Labyrinthitis, Meniere’s disease, and Vestibular Neuritis in the acute level.

Once the acute symptoms stop or subside then the consumption of medicine must be stopped at once.
