Prescription Medications for Vertigo: A Comprehensive Overview

Vertigo, a disorienting sensation of spinning or dizziness, can significantly impact a person's quality of life. While some cases may be managed with over-the-counter remedies, more severe or persistent vertigo often requires prescription medications. This article explores the various prescription drugs commonly used to treat vertigo, their mechanisms of action, and potential side effects.

One of the most frequently prescribed medications for vertigo is Meclizine, also known by brand names such as Antivert. Although available over-the-counter in lower doses, higher-strength prescription versions are often recommended for more severe cases. Meclizine works by reducing the activity in the vestibular system, the part of the inner ear responsible for balance. It's particularly effective for vertigo caused by vestibular disorders. Side effects may include drowsiness and dry mouth.

Betahistine, marketed as Serc in many countries, is another popular prescription medication for vertigo. While not FDA-approved in the United States, it's widely used internationally, especially for Meniere's disease-related vertigo. Betahistine is thought to improve blood flow in the inner ear and reduce pressure in the endolymphatic system. Common side effects are mild and may include headache or upset stomach.

For vertigo associated with migraines, doctors may prescribe medications typically used for migraine prevention. These can include beta-blockers like Propranolol, calcium channel blockers such as Verapamil, or certain antidepressants like Amitriptyline. These drugs work by affecting various neurotransmitters and blood vessels in the brain, potentially reducing the frequency and severity of vertigo episodes associated with migraines.

Diuretics, such as Hydrochlorothiazide or Acetazolamide, are often prescribed for Meniere's disease and other conditions where fluid buildup in the inner ear contributes to vertigo. These medications help reduce fluid retention, potentially alleviating vertigo symptoms. However, they can cause electrolyte imbalances and dehydration, so careful monitoring is necessary.

In cases of severe, acute vertigo attacks, short-term use of vestibular suppressants like Diazepam (Valium) or other benzodiazepines may be prescribed. These medications work by depressing the central nervous system, reducing the intensity of vertigo symptoms. Due to their potential for dependence and other side effects, they are typically only used for short periods under close medical supervision.

Corticosteroids, such as Prednisone, are sometimes prescribed for vertigo, particularly when inflammation is suspected to be a contributing factor. They can be effective in reducing inflammation in the inner ear or along the vestibular nerve. However, long-term use can lead to significant side effects, so they're usually prescribed for short courses.

For vertigo caused by vestibular neuritis or labyrinthitis, antiviral medications like Acyclovir may be prescribed if a viral infection is suspected. These drugs work by inhibiting viral replication, potentially reducing inflammation and speeding recovery.

In some cases, antiemetic medications such as Ondansetron or Promethazine may be prescribed to manage nausea and vomiting often associated with severe vertigo episodes. While these don't treat the underlying cause of vertigo, they can provide significant symptomatic relief.

It's important to note that the choice of prescription medication for vertigo depends on various factors, including the underlying cause, severity of symptoms, and individual patient characteristics. Some patients may require a combination of medications or may need to try several different options before finding the most effective treatment.

Moreover, prescription medications are often used in conjunction with other therapies, such as vestibular rehabilitation exercises or dietary modifications.
