Sumatriptan has been reported to increase the risk of a heart attack or a life-threatening change in a person's heart rhythm (arrhythmia). You should not take sumatriptan if you have heart disease or a history of a heart attack, stroke, or transient ischemic attack (TIA or "mini-stroke").
If you have risk factors for heart disease (see Heart Disease Risk Factors), it is also strongly recommended that you take your first dose of sumatriptan in your healthcare provider's office. This way, your healthcare provider can monitor your heart.
In some cases, a stroke or transient ischemic attack can be misdiagnosed as a migraine. Before prescribing sumatriptan, your healthcare provider should make sure you are not having a stroke, especially if you have never had migraines in the past.
However, for more details please talk to the doc/pharmacist who prescribed the med, take care, be well & safe.
