Can taking migraine medications too often be harmful?
Yes; migraine medications can become a cause of headaches if taken too often. When medications are taken two or more days a week, a condition called “chronic daily headaches” can develop in which headaches occur on a daily basis. Medications that have a tendency to cause this problem include ergotamine, opioids (such as codeine), butalbital (Fiorinal), and caffeine-containing medications.
