The manufacturer (GlaxoSmithKline Inc.) encourages clinicians to report suspected adverse events to its Product Surveillance Department (1-800-334-4153).
Sumatriptan is contraindicated in patients with coronary artery disease.
Chest discomfort is usually noncardiac in origin. A survey of 453 migraine patients found chest symptoms occurred in up to 58% of patients in at least some attacks and in up to 42% of patients in all attacks.
One study of 735 consecutive migraine patients reported that chest symptoms are frequent, but rarely important adverse effects of (primarily subcutaneous) sumatriptan (the active ingredient contained in Imitrex Statdose) The risk of chest symptoms was patient-dependent and not related, even opposite, to cardiovascular disease. This report contradicts the hypothesis that chest symptoms after sumatriptan are caused by cardiac ischemia.
Another study of 125 patients concluded that panic-like symptoms may explain the chest pain and related side effects after sumatriptan administration in patients with high levels of anxiety.
Cardiovascular side effects including serious, sometimes fatal cardiac events such as ventricular fibrillation, transient myocardial ischemia, ventricular tachycardia, and coronary artery vasospasm sometimes resulting in myocardial infarction have been reported following the administration of sumatriptan injection. Serious and/or life threatening arrhythmias including atrial fibrillation, ventricular fibrillation, ventricular tachycardia, myocardial infarction, ECG changes suggestive of myocardial ischemia and symptoms consistent with angina pectoris have been reported after administration of oral sumatriptan. Cardiomyopathy, colonic ischemia, Prinzmetal variant angina, thrombophlebitis, angioedema, cerebrovascular accident, pulmonary embolism, shock, subarachnoid hemorrhage, hypertension, bradycardia, and precordial distress have also been reported. In addition, nonspecific EKG changes including ST and T wave changes, prolongation of the PR and QTc intervals, ectopy, and syncope have been reported.
Hematologic side effects including hemolytic anemia, thrombocytopenia, pancytopenia, and cyanosis have been reported.
One report has suggested that "throat tightness" and chest pain associated with sumatriptan (the active ingredient contained in Imitrex Statdose) may sometimes be attributable to changes in esophageal motility.
General side effects including atypical sensations such as tingling, warm or hot sensations, flushing, feeling of tightness, neck stiffness, feeling of heaviness, and other sensations have been reported frequently.
Hypersensitivity side effects including rash, urticaria, pruritus, erythema, and shortness of breath have been reported. Life threatening and fatal anaphylaxis/anaphylactoid reactions have been reported rarely.
Local side effects including reactions at the site of subcutaneous injection have been reported and have included lipoatrophy, lipohypertrophy, pain, burning, swelling, and redness.
Hepatic side effects including disturbances of liver function tests and hepatic impairment have been reported.
Renal side effects including acute renal failure and angioneurotic edema have been reported.
Visual disorders may also be a part of a migraine attack.
Ocular side effects including loss of vision, vision alterations, intraocular disorders, ischemic optic neuropathy, periorbital edema, temporal arteritis, retinal vein thrombosis, and retinal artery occlusion have been reported. Both significant partial vision loss and transient or permanent blindness have been reported very rarely.
One case of sumatriptan-induced cortical stroke has been reported in a patient with sagittal sinus thrombosis.
Sumatriptan (the active ingredient contained in Imitrex Statdose) should be used with caution in patients with a history of epilepsy or conditions associated with a lowered seizure threshold.
Nervous system side effects including anxiety have been reported frequently. Paresthesias, dizziness, and headache have also been reported. Seizures and strokes have rarely been reported. Central nervous system vasculitis, cerebrovascular accident, dysphasia, serotonin syndrome, and subarachnoid hemorrhage have been part of postmarketing events which have been reported. Five cases of akathisia including one together with acute oral dystonia have been reported. Cases of intracranial hemorrhages as well as transient hemiplegia and hemiparesis have also been reported.
Gastrointestinal side effects including abdominal discomfort, dysphagia, nausea, vomiting, ischemic colitis with rectal bleeding, xerostomia, and diarrhea have been reported. Two cases have been reported by Mayo Clinic researchers documenting the association between use of sumatriptan (the active ingredient contained in Imitrex Statdose) and mesenteric ischemia (a condition characterized by acute cramping, abdominal pain, and bloody diarrhea).
Patients receiving sumatriptan should discontinue the use of the medication and consult with their physician immediately if they experience abdominal pain with bloody diarrhea.
Endocrine side effects have been suggested in one study which reported that sumatriptan (the active ingredient contained in Imitrex Statdose) may increase the secretion of growth hormone by the anterior pituitary.
Dermatologic side effects including exacerbation of sunburn and photosensitivity have been reported.
Other side effects including dysphasia, xerostomia, angioneurotic edema, cyanosis, temporal arteritis, deafness, and death have been reported.
