A review of 13 studies finds aspirin can reduce the pain of migraine within two hours for over 50 percent of people.

But experts who used between 900 and 1,000 milligrams of aspirin stress it can cause side effects. They say more research is needed to establish the effectiveness of aspirin compared with other drugs.
