Product Description
Migraine prevention with Flunarizine (Flunarizine HCl) FLURIN capsule — a Calcium Channel Blocker that works daily to prevent migraines, not to treat acute attacks. It blocks calcium influx into vascular smooth muscle, reducing the vasoconstriction cascade that triggers migraine pain.
According to the WHO, migraine affects approximately 14% of the global population and ranks among the leading causes of disability in working-age adults. Randomized controlled trials show that flunarizine 5 mg daily reduces migraine frequency by more than 50% in responding patients.
FLURIN is manufactured by THAN PHARMA Co., Ltd., a Thai pharmaceutical company registered with the Thai FDA (อย.). Each capsule contains flunarizine 5 mg, suitable for patients with migraine occurring 2+ times per month, or chronic vertigo.
⚠️ Not suitable for patients with Parkinson's disease, history of depression, or pregnancy. Consult a pharmacist before use.

About FLURIN
What is Flunarizine?
Flunarizine is a selective Calcium Channel Blocker (CCB) that acts on cerebrovascular and inner-ear smooth muscle. It inhibits calcium ion influx, reducing vasospasm — one of the key mechanisms triggering migraine attacks.
FLURIN contains flunarizine 5 mg per capsule and is classified as a prophylactic agent, meaning it must be taken daily for prevention rather than at the onset of a headache. It also improves blood flow to the inner ear, helping with chronic vertigo.
Flunarizine has been approved in the EU since the 1980s and is recognized in international migraine prevention guidelines.
What does FLURIN treat?
FLURIN (Flunarizine 5 mg) has two primary indications:
1. Migraine Prophylaxis
For patients with migraine occurring ≥2 times per month or severe migraines disrupting daily life. Flunarizine reduces frequency and severity when taken continuously for 2–3 months.
2. Vertigo (Labyrinthine / Vestibular)
Improves circulation to the inner ear and cerebellum, reducing frequency and severity of vertigo episodes.
FLURIN does not treat acute headaches, fever, or other pain types.
How to take FLURIN / Dosage
How to take FLURIN (flunarizine 5 mg):
🌙 Take 1 capsule at bedtime every night — bedtime dosing minimises daytime drowsiness.
📅 Take continuously for 2–3 months before expecting full benefit.
💊 Standard adult dose: flunarizine 5 mg once daily. Do not self-increase dose.
⚠️ Not recommended for children under 15, and the elderly may benefit from 5 mg every other day.
Missed dose: take as soon as remembered; if close to the next dose time, skip the missed one — never double-dose.
Side effects of FLURIN
Common side effects of flunarizine:
😴 Drowsiness — most common; mitigated by bedtime dosing.
⚖️ Weight gain — seen with long-term use due to increased appetite.
😔 Depressive mood — risk is higher in patients with prior depression history.
🤸 Less common: Extrapyramidal symptoms (tremor, stiffness) especially in elderly or with use beyond 3 months.
If side effects are severe or disabling, consult a pharmacist to adjust flunarizine 5 mg dosing or switch therapy.
Contraindications & Precautions
Do not use flunarizine if you have:
🚫 Parkinson's disease or extrapyramidal disorders — flunarizine worsens symptoms.
🚫 History of severe depression.
🚫 Pregnancy or breastfeeding — insufficient safety data.
⚠️ Precautions:
• Elderly: higher risk of extrapyramidal effects; use lower dose.
• Hepatic impairment: reduce dose — flunarizine is hepatically metabolised.
• Driving/operating machinery: avoid early in treatment due to drowsiness.
• Alcohol: amplifies sedative effect; minimise intake.
Drug Interactions with FLURIN
Key drug interactions with flunarizine:
⚠️ Drugs to use with caution alongside flunarizine:
• CNS depressants / sleeping pills / benzodiazepines: additive sedation.
• Alcohol: enhanced CNS depression.
• Other calcium channel blockers: may cause excessive blood pressure lowering.
• Antidepressants: possible interaction; notify prescriber.
✅ Flunarizine 5 mg can generally be taken with paracetamol.
Always inform your pharmacist about flunarizine use before starting any new medication.
How quickly does FLURIN work?
Flunarizine is not a fast-acting analgesic — it accumulates in the body as a prophylactic.
📅 Timeline:
• Weeks 4–8: Noticeable reduction in migraine frequency or severity.
• 2–3 months: Clear, clinically significant improvement.
• 6 months: Full assessment of treatment success.
The half-life of flunarizine 5 mg is approximately 18–19 days, meaning plasma levels gradually accumulate to a therapeutic steady-state.
If no improvement after 3 months, consult a pharmacist or physician for alternatives.

Frequently Asked Questions
Flunarizine 5 mg is the standard dosage of flunarizine, a selective Calcium Channel Blocker used to prevent migraines and reduce vertigo. The '5 mg' refers to the amount of active ingredient per capsule — the most widely studied and used dose for migraine prophylaxis.
Drowsiness is a normal side effect of flunarizine. Managing it: always take at bedtime (not in the morning), avoid alcohol and sedatives, and do not drive until you know how the medication affects you. If drowsiness is severely disabling, consult a pharmacist about dose adjustment.
Flunarizine must be taken continuously for 2–3 months before meaningful migraine prevention is seen. Its half-life of 18–19 days means it takes weeks to reach a therapeutic steady-state. Do not stop early — assess effectiveness at the 3-month mark.
If you remember early in the day, take it as soon as you remember. If it is close to the next dose time, skip the missed dose. Never take a double dose. Missing one dose of flunarizine will not significantly affect its efficacy due to its very long half-life.
It is not recommended. Alcohol amplifies the sedative effect of flunarizine, increasing drowsiness and the risk of falls or accidents. If you drink occasionally, allow at least 4–6 hours between alcohol and your flunarizine 5 mg dose.
Flunarizine is a Calcium Channel Blocker, as are some blood pressure medications (e.g. Amlodipine). Combining them may cause excessive blood pressure reduction. Always inform your pharmacist if you are on antihypertensives before starting flunarizine.
Not recommended. There is insufficient safety data for flunarizine in pregnancy or breastfeeding. If you are pregnant or planning to become pregnant, consult a physician or pharmacist for safer migraine prevention alternatives.
Yes — weight gain is a documented side effect of flunarizine, particularly with long-term use. It is believed to increase appetite via dopamine pathway effects. If this is a concern, discuss diet management and treatment duration with your pharmacist.
