The objective of this study is to examine the efficacy of gabapentin for the treatment of hemicrania continua (HC) in cases where patients had difficulty tolerating indomethacin due to adverse effects. A retrospective chart review of nine patients with HC between October 2006 and February 2008. Inclusion criteria included men and women age 18 or above presenting to the headache center with a headache that meets International Headache Society criteria for HC including a response to indomethacin, but were not able to continue on indomethacin secondary to adverse effects. Four patients report being pain free, three patients report a 50-80% reduction of pain, one patient reports a 10% reduction of pain, and one patient reports no change in pain. Seven out of nine patients demonstrated at least a 50% reduction of pain on gabapentin, four patients becoming completely pain free.
