Abstract
Cluster headache (CH) is a debilitating primary headache disorder. Although uncommon, affecting only 0.1% of population, it is one of the most painful conditions known to humankind. Three strategies are employed for effective treatment of CH, namely, abortive therapy, transitional therapy, and preventive therapy. Being an uncommon condition, there is a paucity of large-scale controlled trials and evidence of various therapies are based on smaller studies. This review primarily focuses on therapies with highest quality of evidence and also on the emerging therapies for CH.
