How are preventative medicines used for migraines?

ANSWER

If you take preventive meds at the first sign of a migraine, they may stop the process that causes the pain. These medications can also stop the headache itself. They work by narrowing the brain’s blood vessels, bringing them back to normal, and relieving the throbbing pain.
