Sibelium<\/strong> inneh\u00e5ller flunarizine 5 mg \/ 10 mg<\/strong> tablets from Janssen Pharmaceuticals — a selective calcium-channel blocker with antihistaminic and anti-dopaminergic activity<\/strong>, anv\u00e4nds som en first-line preventive for episodic and chronic migraine<\/strong> in Europe, Asia, and South America (not FDA-approved in the US). Standard dose: 10 mg nightly for adults, 5 mg nightly for patients <40 kg or >65 years<\/strong>. Full effect at 6-8 weeks. Reduces migraine frequency by 50-70% in responders — one of the most effective oral migraine preventives in head-to-head trials, matched only by topiramate. Particularly useful for: childhood and adolescent migraine (≥5 years), vertiginous \/ vestibular migraine, hemiplegic migraine, and cyclic vomiting syndrome. Main side effects: weight gain (in ~15%)<\/strong>, sedation, and — with long-term use — drug-induced parkinsonism and depression<\/strong> (dopaminergic blockade). Maximum recommended continuous duration 6 m\u00e5nader<\/strong>, with a planned washout.<\/p>\n<\/div>\n Sibelium is an oral tablet of flunarizine 5 mg \/ 10 mg<\/strong> from Janssen Pharmaceuticals, supplied in 30-180 tablet packs. Flunarizine is a piperazine-derivative selective calcium-channel blocker with additional antihistaminic (H1<\/sub>) and weak anti-dopaminergic (D2<\/sub>) activity. It has been widely used in Europe since the 1980s as Sibelium<\/strong> (original Janssen brand) for migraine prophylaxis and vestibular disorders. Not FDA-approved in the US — hence unfamiliar to many US-trained physicians despite being first-line in European, Asian, and Latin American headache guidelines.<\/p>\n Flunarizine’s migraine efficacy is thought to involve four mechanisms:<\/p>\n Why the 6-month limit?<\/strong> Flunarizine’s weak dopamine-receptor antagonism is cumulative. With >6 months of continuous use, the risk of drug-induced extrapyramidal side effects (parkinsonian tremor, bradykinesia, akathisia) rises, particularly in older patients. Planned washouts of 1-3 months allow dopaminergic receptor recovery.<\/p>\n Mycket vanligt (>10%):<\/strong><\/p>\n Vanliga (1-10%):<\/strong><\/p>\n Important long-term (months to years of continuous use):<\/strong><\/p>\n F\u00f6rvara under 25\u00b0C.

If no response at 8 weeks on 10 mg, switch agent (topiramate<\/a>, propranolol<\/a>, amitriptyline).<\/p>\n Flunarizine weakly blocks dopamine receptors. With continuous use beyond 6 months, the risk of drug-induced parkinsonism (tremor, rigidity, slowness) and depression rises. A planned washout of 1-3 months every 6 months allows dopaminergic recovery. If migraines remain controlled after a washout, you may not need to restart; if they recur, restart with a new 6-month course.<\/p>\n Yes for about 15% of users — up to 5-10 kg over 6 months. Mechanism: antihistaminic appetite increase. If weight gain is concerning, topiramate<\/a> (causes weight loss) or propranolol<\/a> (weight-neutral) are alternatives.<\/p>\n No — insufficient safety data and dopaminergic drugs are generally avoided in pregnancy. For pregnant migraineurs, propranolol<\/a> is the preferred preventive; amitriptyline is a second option.<\/p>\n Yes — flunarizine is one of the preferred migraine preventives in European paediatric neurology (age 5+), typically 5 mg at bedtime. Paediatric trials have shown similar efficacy to adult data. Same 6-month course limit applies.<\/p>\n Yes — flunarizine is licensed for vestibular vertigo (Ménière’s, peripheral vertigo, vestibular migraine). The antihistaminic and calcium-channel-blocking actions reduce vestibular excitability. Dose is the same as for migraine.<\/p>\n Janssen never pursued FDA approval. It is widely available in Europe, Asia, Latin America, and Canada as a first-line migraine preventive. US patients sometimes access it via international pharmacies.<\/p>\n You can buy Sibelium (flunarizine 5 mg \/ 10 mg, 30-180 tablet packs) from MedsBase with discreet packaging and worldwide shipping.<\/p>\n \ud83d\udce6 Varje best\u00e4llning omfattas av v\u00e5r Reshipment Assurance Policy<\/strong><\/a> \u2014 om din f\u00f6rs\u00e4ndelse inte anl\u00e4nder inom 20 arbetsdagar, skickar vi om den.<\/p>\n <\/p>\n Andra produkter inom Kroniska tillst\u00e5nd<\/strong> som kunder \u00e4ven tittar p\u00e5:<\/p>\n Sibelium is flunarizine 5 mg \/ 10 mg oral tablets from Janssen \u2014 selective calcium-channel blocker with antihistaminic and anti-dopaminergic action.
