Flunarizine is a medication used for several indications, including migraine prophylaxis, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.

Dosage: The dosage of flunarizine may vary depending on the condition being treated. Here are some general guidelines:

• For migraine prophylaxis: The recommended dosage for adults is 10 mg taken at night. For patients weighing below 40 kg, the recommended dosage is 5 mg.
• For pediatric patients under 12 years: The safety and effectiveness of flunarizine have not been established at this time. In general, children under 12 years of age should not use this medicine.
• For patients with hepatic impairment: Flunarizine is hepatically metabolized, so caution should be exercised when using it in patients with hepatic impairment. A starting dose of 5 mg/day in the evening is recommended. If there is no response after 8 weeks, the patient will need further evaluation.

It's important to note that flunarizine is usually prescribed by a specialist and may not be available in all countries.

Please consult with a healthcare professional for personalized advice and guidance regarding the indication and dosage of flunarizine based on your specific condition and medical history.
