Generic Serc Information

Introduction

Serc is a medication containing the active compound betahistine, classified within the general‑health group of drugs. It is primarily used to relieve the symptoms of vestibular disorders, especially Ménière’s disease and associated vertigo. In Hong Kong, Serc is available through licensed pharmacies and, for patients seeking more affordable options, through our online pharmacy that sources verified generic products. Betahistine improves inner‑ear blood flow and stabilizes the vestibular system, reducing the frequency and severity of dizzy spells.

What is Serc?

Serc is a tablet formulation that delivers betahistine, a histamine‑like agent that acts on the vascular system of the inner ear. The product was originally developed by Boehringer Ingelheim under the brand name Betaserc.

Serc is the generic version of Betaserc, containing the same active compound Betahistine. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. The medication is manufactured in accordance with Good Manufacturing Practice (GMP) standards and is approved by the Hong Kong Department of Health for the indicated vestibular conditions.

How Serc Works

Betahistine is a weak agonist of the histamine H₁ receptor and an antagonist of the H₃ receptor. Stimulation of H₁ receptors causes vasodilation of the stria vascularis in the cochlea, enhancing microcirculation and reducing endolymphatic pressure. Blocking H₃ receptors increases the release of endogenous histamine, further supporting vasodilatory effects. Together, these actions improve the oxygen and nutrient supply to the inner ear, stabilising vestibular function and diminishing vertigo.

Onset of symptom relief typically occurs within a few days of regular dosing, while the therapeutic effect persists as long as the drug is taken. Betahistine has a plasma half‑life of roughly 3 hours, and it is cleared mainly by renal excretion of unchanged drug.

Conditions Treated with Serc

• Ménière’s disease – a chronic disorder characterised by episodic vertigo, fluctuating hearing loss, tinnitus, and aural fullness. Betahistine reduces the frequency and intensity of vertiginous attacks.
• Benign paroxysmal positional vertigo (BPPV) – while repositioning manoeuvres remain first‑line, betahistine may be added to lessen residual dizziness.
• Vestibular hypofunction – patients with reduced vestibular compensation after viral labyrinthitis or vestibular neuritis may benefit from improved inner‑ear perfusion.

In Hong Kong, epidemiological data indicate that vestibular disorders affect up to 1 % of the adult population, with a higher prevalence in middle‑aged adults. Early pharmacologic support with betahistine can improve daily functioning and reduce disability.

Who is Serc For?

• Adults diagnosed with Ménière’s disease who experience two or more vertigo episodes per month.
• Patients with recurrent BPPV who have incomplete response to positional therapy.
• Individuals with vestibular hypofunction where vestibular rehabilitation alone is insufficient.

Serc is not recommended for:

• Children and adolescents under 18 years, as safety data are limited.
• Pregnant or breastfeeding women unless the benefit outweighs potential risk; current data are insufficient to confirm safety.
• Patients with known hypersensitivity to betahistine or any tablet excipients.

Clinicians may avoid Serc in patients with severe renal impairment because the drug is excreted unchanged in urine.

Risks, Side Effects, and Interactions

Common

• Headache
• Nausea or mild gastrointestinal discomfort
• Indigestion (dyspepsia)

These events are usually transient and resolve without medical intervention.

Rare

• Skin rash or pruritus
• Mild palpitations (occasionally reported in patients with pre‑existing cardiac rhythm disorders)

If symptoms persist, patients should seek professional advice.

Serious

• Severe allergic reaction (anaphylaxis), characterised by swelling of the face, throat, or lips, difficulty breathing, and rash. Immediate emergency care is required.
• Sudden, unexplained drop in blood pressure (hypotension).

Serious events are exceedingly uncommon but warrant prompt medical evaluation.

Drug–Drug Interactions

• Antihistamines (e.g., diphenhydramine) may counteract betahistine’s H₁ agonist activity, reducing efficacy.
• Anticholinergic agents can increase the risk of dry mouth and blurred vision when combined with betahistine.
• Renal‑clearance inhibitors (e.g., cimetidine) may modestly raise betahistine plasma levels; dose adjustment is rarely required but clinicians should monitor.

Patients should disclose all concurrent medications, herbal products, and supplements to their healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Typical adult dose: 8 mg to 16 mg taken two to three times daily, usually after meals to minimise stomach upset.
• Missed dose: If a dose is forgotten and the scheduled time is within 6 hours, take it as soon as remembered. Skip the missed dose if it is close to the next scheduled dose; do not double‑dose.
• Overdose: Report any ingestion of more than the prescribed amount to a medical professional or the Hong Kong Poison Centre. Symptoms may include excessive nausea, vomiting, or severe headache. Treatment is supportive; there is no specific antidote.

Precautions:

• Take tablets with food or a glass of water to reduce gastrointestinal irritation.
• Alcohol does not directly interact with betahistine but may exacerbate dizziness; moderation is advised.
• Patients with chronic kidney disease should have renal function assessed before initiating therapy.

FAQ

• Is Serc available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name version is marketed as Betaserc, while generic Serc contains the identical active ingredient betahistine. Generic tablets offer the same therapeutic effect at a lower price point.

• What is the appearance of Serc tablets?
  Serc tablets are typically round, white to off‑white, and may be film‑coated. The imprint usually includes “SERC” together with the strength (e.g., 8 mg or 16 mg).

• Does Serc require special storage conditions?
  The medication should be stored at room temperature, between 20 °C and 25 °C (68 °F–77 °F), away from direct sunlight, moisture, and heat sources. No refrigeration is needed.

• Can Serc be safely imported for personal use in Hong Kong?
  Personal import of a three‑month supply of a prescribed medication is generally permitted under Hong Kong customs regulations, provided the product is accompanied by a valid prescription and originates from a reputable source. Importing generic Serc from our pharmacy complies with these requirements.

• Are there any known differences in the formulation of Serc between regions?
  Formulation may vary slightly in inactive excipients (e.g., filler, binder) to meet regional regulatory standards, but the amount of betahistine per tablet remains consistent worldwide.

• What is the history of betahistine development?
  Betahistine was first synthesized in the 196s and introduced clinically in Europe during the 197s. It gained widespread use after clinical trials demonstrated efficacy in reducing vertigo attacks in Ménière’s disease.

• How does betahistine compare with older vestibular drugs such as cinnarizine?
  Betahistine primarily enhances inner‑ear blood flow without significant sedative effects, whereas cinnarizine has antihistamine and calcium‑channel blocking properties that can cause drowsiness. Clinical guidelines often prefer betahistine for long‑term management of Ménière’s disease.

• Will taking Serc affect blood test results?
  Betahistine does not typically interfere with routine laboratory tests. However, patients undergoing specialized histamine or catecholamine assays should inform the laboratory of their medication.

• Is it safe to travel internationally while using Serc?
  Yes, provided the medication is kept in its original packaging, labeled with the active ingredient, and accompanied by a copy of the prescription. It is advisable to carry a supply for the entire trip in case of customs delays.

• Do the tablets contain any allergens such as lactose or gluten?
  In most formulations, the inert ingredients are free of common allergens, but specific manufacturers may use lactose as a filler. Patients with severe intolerances should verify the excipient list with the supplier.

• Can betahistine be taken together with dietary supplements like magnesium?
  There are no documented adverse interactions between betahistine and magnesium or most vitamins. Nonetheless, patients should disclose all supplements to their healthcare professional to avoid unforeseen effects.
