Flunarizine is employed for the prevention of migraine headaches, typically used when other treatments have proven ineffective. It works by reducing the frequency of migraine attacks and may also alleviate the severity of such attacks.

Belonging to the class of drugs called calcium channel blockers, flunarizine operates by modulating calcium entry into cells. This medication is not effective for treating sudden or acute migraine attacks.
