Generic Sibelium Information

Introduction

Sibelium is a prescription medication that contains the calcium‑channel antagonist flunarizine. It is classified within the pain‑relief group because of its established efficacy in preventing migraine attacks. In Hong Kong, flunarizine is prescribed by neurologists and headache specialists for adult patients who experience frequent or disabling migraine episodes, and, in some cases, for secondary prophylaxis of tension‑type headache. The drug is marketed internationally under several brand names, most notably Sibelium (Servier) and Moditen; generic versions containing the same active compound are widely used to reduce treatment costs.

What is Sibelium?

Sibelium is a oral tablet formulation that delivers flunarizine, a selective antagonist of L‑type calcium channels. Flunarizine was first synthesized in the 197s by French pharmacologists and later developed by Servier Pharmaceuticals as the branded product Sibelium. The medication is marketed in many regions, including Europe, Asia and the Middle East, under various trade names such as Moditen, Mocarin and Sibelium. While the branded version is produced by the originator, generic flunarizine tablets contain an identical amount of active ingredient and are subject to the same regulatory standards for safety and efficacy.

“Sibelium is the generic version of the original brand Sibelium, containing the same active compound flunarizine. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.”

The tablets are typically supplied in 5 mg strength and are intended for adult use only. The medication belongs to the broader therapeutic class of calcium‑channel blockers, a group more commonly known for treating hypertension and angina, but flunarizine’s unique pharmacologic profile makes it suitable for migraine prophylaxis.

How Sibelium Works

Flunarizine blocks voltage‑dependent L‑type calcium channels in neuronal cell membranes. By reducing calcium influx, the drug stabilizes neuronal excitability and diminishes the release of excitatory neurotransmitters such as glutamate and substance P. These actions attenuate cortical spreading depression—a wave of neuronal depolarisation that is believed to trigger migraine aura and the subsequent headache phase.

In addition to calcium‑channel blockade, flunarizine exhibits antihistamine and weak antiserotonergic properties, which may contribute to its preventive effect on migraine by modulating central serotonergic pathways. The therapeutic onset generally occurs after 2–3 weeks of continuous dosing, with maximal prophylactic benefit observed after 1–2 months. Flunarizine’s elimination half‑life is approximately 20 hours, allowing once‑daily dosing with steady plasma concentrations.

Conditions Treated with Sibelium

• Migraine prophylaxis (with or without aura) – Clinical trials have demonstrated a ≥50 % reduction in monthly migraine days for a majority of patients receiving 5 mg flunarizine. In Hong Kong, migraine prevalence among adults is estimated at 10–12 %, making preventive therapy a public‑health priority.
• Chronic tension‑type headache – While not a first‑line agent, flunarizine may reduce headache frequency when conventional analgesics are insufficient.
• Secondary prophylaxis after medication‑overuse headache – Flunarizine is sometimes employed to stabilize headache patterns after withdrawal of overused analgesics.

Off‑label uses reported in the literature include vestibular migraine and certain movement‑disorder symptoms, but these indications are not formally approved by the Hong Kong Department of Health.

Who is Sibelium For?

Sibelium is appropriate for adult patients (≥18 years) who experience:

• Four or more migraine days per month despite acute rescue medication, suggesting a need for prophylaxis.
• Migraine with disabling aura where attack frequency interferes with occupational or social functioning.
• Refractory tension‑type headache that does not respond adequately to standard analgesics or non‑pharmacologic measures.

Contra‑indications include patients with known hypersensitivity to flunarizine or any excipients, severe hepatic impairment, and uncontrolled depression or suicidal ideation. Caution is advised in individuals with:

• Parkinsonian syndromes – flunarizine may exacerbate extrapyramidal symptoms.
• Psychiatric disorders – rare cases of depressive mood changes have been reported.
• Pregnancy or lactation – safety data are insufficient; the drug should be avoided unless the potential benefit outweighs the risk.

Elderly patients may require dose adjustment due to slower drug clearance and increased susceptibility to sedation or weight gain.

Risks, Side Effects, and Interactions

Common

• Drowsiness or fatigue
• Weight gain (typically ≤5 % of baseline body weight)
• Dry mouth
• Constipation

These events are dose‑related and often subside after the first few weeks of therapy.

Rare

• Mood alterations, including depressive symptoms or anxiety
• Extrapyramidal signs such as tremor or rigidity (particularly in patients with underlying movement disorders)
• Elevated liver enzymes (monitoring recommended in patients with pre‑existing hepatic disease)

Serious

• Severe depression with suicidal ideation – requires immediate medical attention.
• Clinically significant hepatotoxicity – rare but warrants discontinuation and hepatic function testing.

Drug‑drug interactions

• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) may increase flunarizine plasma levels, enhancing side‑effect risk.
• CNS depressants (e.g., benzodiazepines, antihistamines) can potentiate sedation.
• Antidepressants (especially selective serotonin reuptake inhibitors) should be used cautiously due to overlapping serotonergic activity.

Patients should inform their healthcare provider of all concurrent medications, herbal products, and supplements.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose: 5 mg (one tablet) taken once daily in the evening, with or without food.
• Dose titration: In some patients, a lower dose of 2.5 mg may be initiated for tolerability, then increased to the target 5 mg after 1–2 weeks.
• Missed dose: If a dose is forgotten, take it as soon as remembered unless it is close to the next scheduled dose; in that case, skip the missed tablet and continue with the regular regimen. Do not double‑dose.
• Overdose: Symptoms may include profound drowsiness, hypotension, or cardiac conduction abnormalities. Immediate medical evaluation is recommended.
• Precautions: Avoid alcohol while taking flunarizine, as it can amplify sedative effects. Patients with severe renal impairment should be monitored, although dosage adjustment is not routinely required.

Regular follow‑up after 4–6 weeks of therapy is advisable to assess efficacy, tolerability, and weight changes.

FAQ

• Is flunarizine available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Sibelium, while several generic manufacturers produce identical 5 mg tablets containing flunarizine. Generic options are typically less expensive and meet the same regulatory standards.

• What storage conditions are recommended for Sibelium tablets?
  Store the tablets at a controlled room temperature of 15–30 °C, away from direct sunlight, moisture and heat sources. Do not refrigerate or freeze the medication, as extreme temperatures may affect tablet integrity.

• How does the appearance of generic flunarizine tablets differ from the branded version?
  Branded Sibelium tablets are usually white, oval‑shaped, and embossed with “Sibelium 5 mg”. Generic tablets may vary in shape (round or oblong) and may bear the manufacturer’s logo and dosage strength. Inactive ingredients such as lactose or microcrystalline cellulose can also differ between brands.

• Can Sibelium be imported for personal use without a local prescription in Hong Kong?
  Personal importation of prescription‑only medicines requires a valid prescription from a licensed Hong Kong practitioner and compliance with customs regulations. Importing without proper documentation may result in seizure of the product and legal penalties.

• Are there any special warnings for Asian populations taking flunarizine?
  Clinical data do not indicate ethnicity‑specific safety concerns. However, clinicians may monitor body weight and liver function more closely in any population because weight gain and hepatic enzyme elevations have been reported, albeit rarely.

• Does the formulation of flunarizine differ between the European Union and Asian markets?
  The active ingredient and dosage strength (5 mg) are consistent worldwide. Differences may exist in excipients, tablet coating, and packaging to meet regional regulatory requirements. Such variations do not affect the pharmacologic activity of flunarizine.

• What is the recommended interval for monitoring weight while on Sibelium?
  Baseline be recorded before initiating therapy. Follow‑up measurements are advisable at 4–6 weeks, then every 3 months thereafter, especially for patients with obesity risk factors or those reporting increased appetite.

• How does flunarizine compare with beta‑blockers for migraine prevention?
  Both classes are effective for migraine prophylaxis, but flunarizine offers additional antihistamine and antiserotonergic effects that may benefit patients with aura or vestibular symptoms. Beta‑blockers are contraindicated in asthmatic patients, whereas flunarizine requires caution in those with depression. Choice of therapy should be individualized based on comorbidities and side‑effect profiles.

• Can Sibelium be taken together with herbal supplements such as ginkgo biloba?
  Ginkgo biloba has mild antiplatelet activity. When combined with flunarizine, there is no known pharmacokinetic interaction, but the additive effect on platelet function could increase bleeding risk in susceptible individuals. Consultation with a healthcare professional is advisable before concurrent use.

• What travel precautions should a patient on flunarizine observe?
  Keep tablets in original packaging with a copy of the prescription to satisfy customs authorities. Maintain the medication at room temperature and avoid exposure to extreme heat (e.g., leaving tablets in a car on a hot day). Carry the medication in hand luggage to prevent loss during checked‑baggage handling.
