A migraine is a headache of varying intensity, often accompanied by nausea and sensitivity to light and sound. Migraines can last anywhere from 4 to 72 hours, and even the most basic activities can amplify your symptoms. This includes noise, light, and moving around. The FDA just approved a first-of-its-kind drug intended to prevent migraines. It comes in an auto-injector device where you inject yourself once a month at a list price of $575 a pop. The new drug, known as Aimovig, attacks viruses and other intruders. Aimovig is an antibody that works just like the antibodies that are created by our immune system. The company has to study whether people who take this drug are more at risk for stroke, liver toxicity, and heart attacks.
