Migon 5 Tablet is a prescription-only medication containing flunarizine 5mg as the active ingredient. It is a calcium channel blocker primarily used in the prophylactic treatment of migraine and cluster headaches. Flunarizine, a structurally distinct calcium channel blocker, has a distinct mechanism of action, which involves stabilization of the calcium channel, thereby reducing the influx of calcium ions into the neuron, subsequently diminishing the release of pain mediators. Migon 5 Tablet has been shown to be effective in reducing the frequency and severity of migraine and cluster headaches, as well as improving quality of life. It is available in tablet form and should be taken orally with or without food. The recommended starting dose is one tablet daily, with dosage adjustments as necessary. Migon 5 Tablet is contraindicated in patients with a history of seizure disorders, and caution should be exercised in patients with liver or kidney impairment. Common side effects include dizziness, headache, and fatigue.
