Caffeine Timeline


Both the WHO and the APA consider the effects of caffeine and the intoxication from caffeine to be a valid diagnosis. Doses vary from individual to individual. While rarely fatal, symptoms can include anxiety, insomnia, tremors, fever, rapid heartbeat (tachycardia), and hyperventilation (tachypnea).

Often when caffeine intoxication is fatal , the user consumed caffeine pills and his death was due to ventricular fibrillation—the muscles in the heart go out of whack, causing it to pump inadequately and depriving the body of oxygen. Thus the effects of caffeine can range from mild tremors to fatality.
