What is Caffeine Use Disorder?

Caffeine is the most widely consumed psychoactive substance in the world. While safe at moderate intake (up to about 400 mg daily for healthy adults), excessive consumption (often over 600 mg daily) can produce problematic effects. DSM-5 includes caffeine intoxication and caffeine withdrawal as defined disorders, and lists caffeine use disorder as a condition for further study.

Caffeine use disorder is characterized by a persistent desire or unsuccessful efforts to cut down, continued use despite known physical or psychological problems, and withdrawal-related distress. Common sources are coffee, tea, energy drinks, soda, chocolate, certain medications, and pre-workout supplements. Individual sensitivity varies based on CYP1A2 polymorphisms.

Caffeine intoxication features include restlessness, nervousness, insomnia, flushed face, diuresis, GI disturbance, muscle twitching, tachycardia, and rambling thought. Caffeine withdrawal causes headache, fatigue, mood disturbance, difficulty concentrating, and flu-like symptoms beginning 12-24 hours after cessation. Treatment includes structured taper, education, hydration, behavioral substitution, and management of comorbid anxiety, insomnia, and migraine.
