Clinical Update: Caffeine and Headache

Preface
The National Headache Foundation (NHF), a non-profit organization dedicated to serve as an information resource to headache sufferers, their families and the healthcare providers who treat them, convened a distinguished, multidisciplinary faculty to review and clarify issues regarding the relationship between caffeine and headache. Our expert panel addressed topics of importance to clinicians involved in diagnosing or treating patients with headache disorders. Specifically, the purpose of the meeting was to:

• Review the professional literature about caffeine and its relationship with headache
  
• Provide detailed analyses of important subtopics, such as safety, efficacy, dosing,
  rebound, withdrawal, and addiction
  
• Summarize findings for medical professionals
  
• Translate relevant information into patient-education materials

This publication, aimed at medical professionals, is intended to provide a scientific summary of published research involving caffeine.
