title: Prophylactic etoricoxib is effective in preventing Yom Kippur headache: a placebo-controlled double-blind and randomized trial of prophylaxis for ritual fasting headache.
abstract: BACKGROUND
  Religious fasting is associated with headache. This has been documented as "Yom Kippur Headache" and "First-of-Ramadan Headache." Rofecoxib (Vioxx®), a cyclooxygenase-2 (Cox-2) inhibitor with a 17-hour half-life, has been shown to be effective in preventing fasting headache when taken just prior to the 25-hour Yom Kippur fast. Unfortunately for fasters rofecoxib is no longer available. We hypothesized that etoricoxib, another Cox-2 inhibitor with a longer half-life, would also be effective in preventing fasting headache.
  
  
  METHODS
  We performed a double-blind randomized prospective trial of etoricoxib 120 mg vs placebo, taken just prior to the onset of fasting, Yom Kippur 2008. Healthy adults aged 18-65 years were enrolled from the community. Subjects completed a demographic data form and questions regarding headache history and a post-fast survey on headache during the fast. We compared incidence, time of onset and intensity of headache, general ease of fasting, and side effects in control and treatment groups.
  
  
  RESULTS
  We enrolled 211 patients and 195 completed the post-fast questionnaire (92%). Of those subjects receiving etoricoxib (n=99), 36 or 36.4% vs 65 or 67.7% of the placebo group (n=96) developed any headache during the fast (P< .0001). Median severity of headache in the treatment group was significantly lower for the treatment group (3.0 vs 5.0 on a visual analog scale of 10; P= .024). Also, participants in the treatment group reported an easier fast than the placebo group, as compared with previous fasting experience (4.0 vs 3.5 on a scale of 1-5; P< .0001).
  
  
  CONCLUSIONS
  Etoricoxib 120 mg taken prior to a 25-hour ritual fast decreases incidence of and attenuates fasting headache.
