BackgroundCaffeine has both excitatory and vasoconstrictive effects on central nervous system. Caffeine use might be associated with development and chronification of migraine. We aimed to evaluate the effect of caffeine cessation on the acute treatment of migraine.

MethodsWe prospectively recruited migraine patients who consumed caffeine drinks daily and instructed them to discontinue their caffeine intake. Triptans were prescribed for acute treatment. Patients were followed up after at least two weeks after screening and evaluated the efficacy of acute treatment with the migraine assessment of current therapy Migraine-ACT questionnaire. Excellent efficacy was defined as Migraine-ACT score of 4. Chronic migraine, body mass index, allodynia, depression, anxiety, antiemetic use, and use of prophylactic medication were included in the multivariate analysis if the univariate p < 0.2.

FindingsAmong 108 patients included, 36 completely discontinued their caffeine intake abstinence group. The efficacy of acute treatment was assessed at median 34.5 days interquartile range, 28–89 after the screening. Twenty-six patients 72.2 % in the abstinence group and 29 40.3 % in the non-abstinence group reported an excellent efficacy p = 0.002. The abstinence group also showed a trend toward greater reduction of headache impact test-6 HIT-6 scores p = 0.085. Caffeine abstinence was independently associated with an excellent efficacy of acute treatment multivariate odds ratio, 3.2; 95 % confidence interval, 1.2–8.4; p = 0.018 after controlling for covariates.

ConclusionsCaffeine abstinence is associated with better efficacy of acute migraine treatment. Our uncontrolled study results encourage a further confirmatory study on this issue.
