Last year, the International Headache Society published a study that found "overuse" of over the counter medicines as a major contributing factor to frequent migraine headache attacks. "Overuse has less to do with how many pills you take to relieve a single headache than with how often you take them," explains Dr. Robert Kunkel, a headache specialist at the Cleveland Clinic Headache Center. "If you get more than two headaches a week and take pain pills for them, you're at risk." Studies showed that pain relievers with caffeine, like Excedrin, were some of the worst culprits for exacerbating proclivity to migraines.
