Flunarizine is a calcium channel antagonist that reduces the frequency and severity of migraine attacks and balances inner ear function. It is mainly indicated for migraine prophylaxis and vestibular disorders like vertigo. This active ingredient is found in various cost-effective generic treatments.

Flunarizine belongs to a group of medicines called calcium-channel blockers. It is mainly used to help prevent certain types of headache and to reduce episodes of dizziness. In the United Kingdom, flunarizine is the active ingredient found in products such as Sibelium and the generic tablet simply called Flunarizine.
Both Sibelium and the generic Flunarizine tablets contain the same active substance. They are usually supplied as oral tablets of 5 mg or 10 mg strength. The brand-name product Sibelium is marketed by a specific pharmaceutical company, while the generic version may be produced by several manufacturers and can be found labelled simply as “Flunarizine.” All of these preparations are authorised by the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) and are available on prescription.

By limiting calcium entry, the drug helps blood vessels stay relaxed and reduces the likelihood of sudden vessel changes that can trigger a migraine or cause dizziness. The effect builds up over a few days, so patients may notice a gradual improvement rather than an immediate change.
