Pure naratriptan-induced ischemic colitis: a case report.

A 60-year-old female with sudden onset of abdominal pain and hematochezia was diagnosed with histology-proven ischemic colitis. She used naratriptan on a regular basis for migraine. By exclusion of other causes for colonic ischemia and the absence of cardiovascular risk factors, naratriptan was considered the causal agent. Discontinuation resulted in a complete clinical recovery. With the increasing use of triptans, health care providers should be aware of the possible serious ischemic events associated with these drugs.
