Caffeine is a commonly used drug that increases alertness, decreases fatigue, and improves muscle coordination. Though coffee comes to mind as the most common source of caffeine, it's also naturally found in tea and chocolate, and it is often added to soft drinks and non-prescription drugs like pain-relievers and cold remedies. People vary in their sensitivity to caffeine. If used excessively, caffeine can be too stimulating and cause anxiety, sleep problems, muscle twitching, or abdominal pain.
How Does Caffeine Treat Headaches?
Caffeine is a common ingredient in many prescription and over-the-counter headache medications (see list below). Caffeine additives make pain relievers 40% more effective in treating headaches. Caffeine also helps the body absorb headache drugs more quickly, bringing faster relief. By adding caffeine and, in turn, taking less medication, you can reduce the risk for potential side effects and possible drug addiction.

How Can I Prevent Caffeine Withdrawal?
Withdrawal from normal caffeine usage is rare. However, with excess use, over 500 mg daily (approximately five cups of coffee) over a long period of time, sudden cessation could cause symptoms of withdrawal. You can avoid caffeine withdrawal by limiting your daily consumption, being educated about sources of caffeine, and by gradually decreasing the consumption rather than ending use abruptly.
Because of the risk of withdrawal, people should not take caffeine-containing pain relievers on a daily basis.
