Warning: Only use sumatriptan nasal when a clear diagnosis of migraine has been established. Serious coronary events, including some that have been fatal, although extremely rare, have occurred. Because of the potential of sumatriptan to cause coronary vasospasm, sumatriptan should not be given to patients in whom unrecognized coronary artery disease (CAD) is likely without first evaluating the underlying cardiovascular disease. The patients in this category include women who are postmenopausal, males over 40 years of age, patients with high blood pressure, high cholesterol, obesity, diabetes, patients who smoke, or patients with a strong family history of CAD.
