How can migraine headache medications lead to high blood pressure?

ANSWER

Some migraine medications work by tightening blood vessels in your head. This relieves migraine pain. However, they also constrict blood vessels throughout your body. This makes your blood pressure rise, perhaps to dangerous levels.

If you have high blood pressure or any other type of heart disease, talk with your doctor before taking a drug for migraines or severe headaches.
