Abstract
Agents including the effect on sodium channel are restricted in patients with Brugada electrocardiogram (ECG) pattern or Brugada syndrome. On the other hand, many therapeutic agents for cluster headache (CH) block sodium channel. After recommended therapies without sodium channel blocking effect were failed in a 40-year-old male with CH whose ECG shows Brugada ECG pattern, clonazepam and codein phosphate, which are exceptional treatments for CH, were effective for severe unilateral orbital pain.
