Harmful pattern of use of caffeine

Last edited: 4/22/2026

Overview

Caffeine, a widely consumed psychoactive substance, primarily affects the central nervous system by antagonizing adenosine receptors. Moderate consumption of caffeine through beverages like coffee and tea is generally not associated with increased mortality risk, except for a slight elevation in risk for acute myocardial infarction in heavy users (≥4 cups/day). 1

Diagnosis

  • No specific diagnostic criteria exist for harmful caffeine use patterns.
  • Assessment typically involves evaluating consumption levels and correlating with symptoms or health outcomes.
  • Management

  • Gradual reduction in caffeine intake is recommended for individuals experiencing adverse effects.
  • No specific drug classes or doses are mentioned for managing harmful caffeine use patterns.
  • Special Populations

  • Pregnancy: No specific guidance provided in the abstracts regarding caffeine use during pregnancy.
  • Pediatrics: Caffeine use in children is noted but without specific recommendations or concerns highlighted.
  • Elderly: No particular considerations or guidelines specific to elderly populations are mentioned.
  • Comorbidities: Heavy coffee consumption (≥4 cups/day) may slightly increase the risk of acute myocardial infarction, warranting caution in individuals with cardiovascular conditions 1.
  • Key Recommendations

  • Moderate consumption of coffee and tea is unlikely to increase overall mortality risk but heavy coffee use (≥4 cups/day) may slightly elevate the risk of acute myocardial infarction 1 (Evidence: Moderate).
  • Caffeine consumption appears safe in moderation and may offer protective effects against liver cirrhosis and suicide risk 1 (Evidence: Moderate).
  • Further research is needed to establish definitive guidelines for caffeine's impact on weight loss and fat oxidation 2 (Evidence: Weak).
