General:

This drug should be used only where a clear diagnosis of migraine has been established; if a patient does not respond, the diagnosis of migraine should be reconsidered before treating subsequent attacks.
This drug is not intended to treat cluster headaches, hemiplegic, or basilar migraines or for the prophylactic treatment of migraines.
Patients with coronary artery disease (CAD) risk factors should have a cardiovascular evaluation performed prior to initiating therapy; for patients who satisfactorily complete a cardiovascular evaluation, consider administering first dose in a medically supervised setting and perform an ECG immediately following administration.
Medication overuse headaches may present as migraine-like headaches or as a marked increase in migraine frequency; for patients using acute migraine medications (e.g. ergotamine, triptans, opioids) for 10 or more days per month consider withdrawal of the overused drugs and treatment of withdrawal symptoms.

Monitoring:

ECG monitoring should be considered in the interval following the first dose in patients with risk factors for coronary artery disease (CAD) who have satisfactorily completed a cardiovascular evaluation, consider periodic cardiovascular evaluation in intermittent long-term users with cardiovascular risk factors.
Monitor blood pressure
Monitor for serotonin syndrome if concomitant use of selective serotonin reuptake inhibitors (SSRIs) or selective norepinephrine reuptake inhibitors (SNRIs) are necessary, particularly when starting therapy or with a new or increased dose of a serotonergic medication.
