What is Vertin?
Vertin, available as 8 and 16 mg film coated tablets, contains Betahistine Hydrochloride, which is an antivertigo drug first used for treating vertigo associated with Meniere’s disease. It is also commonly used for patients with balance disorders.
In what conditions you can use Vertin?
- Meniere’s Disease
- Central Vestibular Disorder
- Cochlear disease
How does Vertin work?
Vertin is thought to work by improving blood flow in the inner ear, which reduces the buildup of pressure. It is this pressure in the ear which is thought to cause the vertigo (dizziness), tinnitus (ringing in the ears) and hearing loss suffered by people with Ménière’s disease
How to take Vertin?
Vertin tablets should be administered orally and the whole tablet has to be swallowed with water (Crushing or chewing the tablet should be strictly avoided.)
The recommended dosage regimen is:
- Initially: 8-16 mg 3 times daily (TID), preferably with food.
- Maintenance dose: 24-48 mg daily
- For acute attacks: Treatments include 8-16mg up to 3 times daily

16mg regularly TID seems most effective in Meniere’s disease
Not recommended for children under the age of 18 years.
It’s best to take Vertin with or after food. This way it’s less likely to upset your stomach.
Take Vertin only under the prescription of a healthcare provider.
What to do if a dose is missed?
If you forget to take a dose, take it as soon as you remember. If you don’t remember until it’s nearly time for the next dose, skip the missed dose. Never take two doses at the same time. Never take an extra dose to make up for a forgotten one.
If you often forget doses, setting an alarm might be helpful to remind you.

Betahistine predominantly interacts with histaminergic receptors. Betahistine has a very strong affinity as an antagonist for histamine H3 receptors and a weak affinity as an agonist for histamine H1 receptors.
- H1 receptor agonist would give rise to local vasodilation and increased permeability which helps to reverse the underlying problem of endolymphatic hydrops. Betahistine seems to dilate the blood vessels within the inner ear which can relieve pressure from excess fluid.
- Betahistine blocks H3 receptors and releases neurotransmitters (histamine, norepinephrine, Ach, GABA). The increased amounts of histamine released from histaminergic nerve endings can stimulate histamine receptors. This stimulation explains the potent vasodilatory effects of betahistine in the inner ear.
Absorption: Rapidly absorbed from the gastrointestinal tract.
Protein binding: Very low (less than 5 %)
Route of elimination: Renal
Half-life: The half life of elimination is 3.5 hours.
- No in-vivo interaction studies have been performed. Based on in-vitro data no in-vivo inhibition on Cytochrome P450 enzymes is expected.
- In vitro data indicate an inhibition of betahistine metabolism by drugs that inhibit monoamino-oxidase (MAO) including MAO subtype B (e.g. selegiline). Caution is recommended when using betahistine and MAO inhibitors (including MAO-B selective) concomitantly.
- Betahistine dihydrochloride should not be used concurrently with antihistamines (As betahistine is an analogue of histamine, interaction of betahistine with antihistamines may in theory affect the efficacy of one of these drugs.).
