Topiramate could potentially effective as prophylaxis for cluster headache, but the experience remains limited in Asians. We performed an open-label clinical study to evaluate the efficacy of topiramate in the tolerable dosage to prevent cluster headache. We studied patients who fulfilled the criteria of episodic or chronic cluster headaches (International Classification of Headache Disorders second edition) prospectively. Headache severity was assessed using a verbal rating scale (excruciating, severe, moderate, mild, and no headache). Treatment was started with a topiramate dose of 50 mg twice daily and was increased by 50-100 mg a day every 3 to 7 days as tolerated to a maximal daily dosage of 400 mg. Of the 12 patients with episodic cluster headache, nine patients had remission of headache at a mean daily dosage of 273 mg (range 100-400 mg ), and the patient with chronic cluster headache had remission at a daily dosage of 400 mg. The adverse effects included: paresthesia (84%), slow speech (54%), and dizziness (46%), but were tolerated by most patients. Two patients discontinued topiramate due to adverse events and one due to lack of efficacy.

This open-label study suggests that topiramate is effective in the treatment of cluster headache in Taiwanese patients.
