Generic Betahistine Information

Introduction

Betahistine is a histamine‑like agent used primarily to alleviate vertigo and other balance‑related symptoms associated with Ménière’s disease and vestibular disorders. In Hong Kong, the medication is available as a generic product containing the active compound betahistine hydrochloride and is classified under the “General health” medication group. It is also prescribed off‑label for some forms of motion sickness and age‑related hearing impairment, reflecting its vasodilatory and neuro‑modulatory properties.

What is Betahistine?

Betahistine is the generic version of the well‑known brand Serc (also marketed as Betaserc in several countries). Both brand and generic formulations contain the same active compound, betahistine hydrochloride. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for patients in Hong Kong who require vestibular relief. The drug was first synthesized in the 196s by the French pharmaceutical company Servier and has since been marketed worldwide for inner‑ear disorders.

How Betahistine Works

Betahistine acts as a weak agonist at histamine H₁ receptors and a competitive antagonist at histamine H₃ receptors. The H₁‑receptor stimulation promotes vasodilation of the inner ear’s stria vascularis, improving microcirculation and reducing endolymphatic pressure. Simultaneously, H₃‑receptor blockade enhances the release of endogenous neurotransmitters such as acetylcholine and norepinephrine, which facilitate vestibular compensation. Clinical onset of symptom relief is usually observed within 1–2 hours after the first dose, and the drug’s half‑life ranges from 2 to 3 hours, allowing for multiple daily dosing to maintain therapeutic levels.

Conditions Treated with Betahistine

• Ménière’s disease – chronic vestibular disorder characterized by recurrent vertigo, tinnitus, and fluctuating sensorineural hearing loss. Betahistine improves vascular flow in the cochlea and reduces the frequency and intensity of vertigo attacks.
• Vestibular neuritis and labyrinthitis – acute inflammatory conditions of the inner ear. Betahistine supports vestibular compensation during the recovery phase.
• Benign paroxysmal positional vertigo (BPPV) – while not first‑line therapy, betahistine may be adjunctive when repositioning maneuvers are insufficient.
• Motion sickness – off‑label use in patients who experience severe nausea during travel; the drug’s antihistaminic activity can mitigate symptoms.

In Hong Kong, Ménière’s disease prevalence is estimated at .2 % of the adult population, making betahistine a frequently prescribed option in otolaryngology and neurology clinics.

Patient Groups Most Likely to Benefit

• Adults aged 18 years and older with a confirmed diagnosis of Ménière’s disease or other vestibular disorders.
• Patients experiencing recurrent, disabling vertigo that interferes with daily activities or work performance.
• Individuals who have limited response to repositioning maneuvers for BPPV and require pharmacologic adjuncts.
• Patients without severe cardiovascular disease, uncontrolled hypertension, or active peptic ulcer disease, as these conditions may increase the risk of adverse effects.

Betahistine is generally contraindicated in patients with known hypersensitivity to the drug, those with pheochromocytoma, or pregnant and lactating women unless the benefits clearly outweigh the risks.

Risks, Side Effects, and Interactions

Common

• Headache
• Nausea or mild gastrointestinal discomfort
• Dyspepsia (indigestion)
• Mild skin rash or pruritus

These events are usually transient and resolve without medical intervention.

Rare

• Transient hypotension, particularly when combined with other vasodilators.
• Increased gastric acidity leading to gastritis in susceptible individuals.

Patients should report persistent or worsening symptoms to their healthcare provider.

Serious

• Severe allergic reactions (anaphylaxis, angioedema).
• Cardiac arrhythmias in patients with pre‑existing conduction abnormalities.

If any serious reaction is suspected, seek emergency medical care immediately.

Drug–Drug Interactions

• Antihistamines (e.g., diphenhydramine) – may blunt betahistine’s therapeutic effect.
• MAO inhibitors – potential for additive vasodilatory effects, increasing the risk of hypotension.
• CYP450 substrates (e.g., certain calcium‑channel blockers) – betahistine is minimally metabolized by CYP enzymes, but clinicians should monitor for unexpected plasma level changes when polypharmacy is extensive.

Patients should provide a full medication list, including over‑the‑counter and herbal products, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 16 mg to 48 mg per day, divided into two or three equal doses (e.g., 8 mg three times daily). The exact dose is titrated based on symptom control and tolerability.
• Administration: Oral tablets taken with or without food; consistency in timing helps maintain steady plasma concentrations.
• Missed dose: If a dose is forgotten, take it as soon as remembered unless it is near the time of the next scheduled dose. Do not double the dose to compensate.
• Overdose: Symptoms may include severe headache, nausea, vomiting, and transient hypotension. In case of suspected overdose, seek urgent medical attention. Gastric lavage is rarely indicated due to the drug’s rapid absorption.
• Precautions: Avoid excessive alcohol, as it may potentiate vestibular side effects. Patients with renal impairment should be monitored, although dose adjustment is not routinely required.

FAQ

• Is Betahistine covered by Hong Kong’s public health insurance schemes?
  Currently, the Hospital Authority does not list betahistine as a reimbursable medication for vestibular disorders. Patients often obtain it via private prescription or through our online pharmacy, which offers competitive out‑of‑pocket pricing.

• Can Betahistine be purchased without a prescription in Hong Kong?
  Betahistine is classified as prescription‑only medication. Our online pharmacy requires a valid prescription from a licensed Hong Kong healthcare professional before dispensing the product.

• What packaging sizes are available when ordering online?
  Our pharmacy offers blister packs of 30 tablets and bulk bottles containing 90 tablets. Packaging is sealed, tamper‑evident, and includes a patient information leaflet in English and Chinese.

• Is cold storage required for Betahistine tablets?
  No. Betahistine tablets should be stored at controlled room temperature, between 15 °C and 30 °C, away from direct sunlight, moisture, and heat sources.

• Are there any special regulations for importing Betahistine into Hong Kong for personal use?
  Importation of a three‑month supply for personal use is permitted under Hong Kong’s Medicines (Commercial Distribution) Ordinance, provided a legitimate prescription accompanies the shipment. Our service assists with the necessary documentation.

• Do Asian populations experience different efficacy or safety profiles with Betahistine?
  Clinical data specific to Asian cohorts are limited, but existing studies have not identified significant ethnic differences in pharmacodynamics or adverse event rates. Physicians may adjust dosing based on individual response.

• Can Betahistine be combined with vestibular rehabilitation therapy (VRT)?
  Yes. Betahistine is often prescribed as an adjunct to VRT to accelerate compensation. The combination does not contraindicate the physical exercises used in VRT.

• What is the typical time frame to notice symptom improvement after starting Betahistine?
  Most patients report reduced vertigo intensity within 1–2 weeks of consistent dosing, though full therapeutic benefit may require 4–6 weeks, especially for chronic Ménière’s disease.

• Is there a generic version of Betahistine that is equivalent to the brand Serc?
  The generic betahistine sold by our online pharmacy contains the same active ingredient, dosage strength, and formulation as the brand‑name Serc, delivering equivalent efficacy at a lower price.

• Can Betahistine be used for children or adolescents?
  Safety and efficacy in patients younger than 18 years have not been established, and the medication is not recommended for pediatric use unless specifically advised by a specialist.

• How does Betahistine differ from antihistamines used for allergy relief?
  Unlike traditional antihistamines that block H₁ receptors, betahistine stimulates H₁ receptors and blocks H₃ receptors, producing vasodilatory and neuro‑modulatory effects rather than pure anti‑allergic activity.

Glossary

Histamine H₁ receptor

A protein on cell surfaces that, when activated, causes vasodilation and increased vascular permeability. Betahistine’s weak agonism at this receptor improves inner‑ear blood flow.

Histamine H₃ receptor

An autoreceptor that modulates the release of several neurotransmitters. Antagonism by betahistine enhances vestibular signaling and aids central compensation.

Vestibular compensation

The brain’s adaptive process to restore balance after an inner‑ear injury or dysfunction. Pharmacologic agents like betahistine can accelerate this neuro‑plastic adaptation.

Ménière’s disease

A chronic disorder of the inner ear characterized by episodic vertigo, fluctuating hearing loss, tinnitus, and a sensation of ear fullness, believed to involve abnormal endolymphatic fluid dynamics.
