Therapeutic Class

Miscellaneous prophylactic migraine preparations


Flunarizine is the difluorinated derivative of cinnarizine. It is a seletive calcium channel antagonist and has H1-receptor blocking action. By reducing excessive transmembrane influx of calcium Flunarizine prevents cellular calcium overlod. It does not interfere with normal cellular calcium homeostasis. Flunarizine also has some antihistaminic and sedative properties.

Dosage & Administration

Migraine Prophylaxis: Starting Dose: 10 mg at night in patients less than 65 years of age and 5 mg daily in patients older than 65 years. If, during this treatment depressive, extrapyramidal or other unacceptable symptoms occur, administration should be discontinued. If, after 2 months of this initial treatment, no significant improvement is observed, the patient should be considered a non-responder and administration should be discontinued. Maintenance Treatment: If a patient is responding satisfactorily and if a maintenance treatment is needed, the dose should be decreased to 5 days treatment at the same daily dose with two successive medicine free days every week. Even if the prophylactic maintenance treatment is successful and well tolerated, it should be interrupted after 6 months and it should be re-initiated only if the patient relapses. Peripheral Vascular disease: 10 mg twice daily, up to 30 mg per day if required. Vertigo & motion sickness: 10-20 mg daily for adults and 5 mg daily for children (> 40 kg). Epileptic seizure: 15-20 mg daily in adults and 5 to 10 mg daily for children as an add-on therapy


Galactorrhoea has been reported in few women on oral contraceptives within the first two months of Flunarizine treatment. Hepatic enzyme inducers such as Carbamazepine and Phenytoin may interact with flunarizine by increasing its metabolism. So an increase in dosage of flunarizine may be required.
