Patented in 1982, Sumatriptan is a headache medicine that narrows blood vessels around the brain. This drug also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms. As for Sumatriptan transdermal, it comes in the form of a skin patch, and uses low voltage controlled by a pre-programmed microchip to deliver a single dose of Sumatriptan through the skin within 30 minutes. Bear in mind that Sumatriptan will only treat a headache that has already begun. Plus, it will not prevent headaches or reduce the number of attacks. Also remember that you should not use Sumatriptan if you have any history of heart disease or coronary artery disease, blood circulation problems, Wolff-Parkinson-White syndrome, uncontrolled high blood pressure, severe liver disease, circulation problems affecting your intestines, history of a stroke, or if your headache seems to be different from your usual migraine headaches. When it comes to the side effects, they include chest pressure, tiredness, vertigo, vomiting, tingling. This drug also has other side effects that are actually more serious such as serotonin syndrome, heart attacks, strokes, and seizures. It is still unclear, though, if using Sumatriptan during pregnancy or breastfeeding is safe.
