Caffeine can be a double-edged sword for those with headache. It can serve as a treatment or, in some cases, can cause withdrawal or a phenomenon known as medicine overuse or "rebound" headache. The important thing to remember is that with education and moderation, caffeine can be an effective treatment for headache.
Caffeine as a headache treatment
Caffeine is a common ingredient in many prescription and over-the-counter headache drugs (see list below). Because analgesics work more quickly and more efficiently with caffeine, patients are able to take less medication. Caffeine additives make pain relievers 40% more effective. Caffeine also helps the body absorb medications more quickly, allowing the patient to feel relief sooner. By adding caffeine and, in turn, taking less medication, the patient reduces the risk for potential side effects and reduces the risk of habitual or addictive usage.

Caffeine and withdrawal
Caffeine withdrawal from normal caffeine usage is rare. However, with excess use, over 500 mg daily (approximately 5 cups of coffee) over a long period of time, sudden cessation could cause symptoms of withdrawal. Patients can avoid caffeine withdrawal by limiting their daily consumption, being educated about sources of caffeine, and by gradually decreasing the caffeine intake rather than ending use abruptly.
Caffeine and rebound headache (medication overuse headache
Rebound headache is a condition that develops from the overuse or misuse of any headache medicine, including those that have caffeine. Medicines that contain caffeine can be beneficial. However, when these medicines are combined with consuming caffeine from other sources, you may be more vulnerable to a rebound headache. Patients should limit caffeine consumption to the equivalent of 2 cups of coffee a day and limit pain medications, either over the counter or prescribed, to 2 days a week to prevent medication overuse headache.
Relief from rebound headache can only be accomplished by completely eliminating all headache medication. However, this should only be done under the supervision of a physician.
