Tolerability of a drug should be regarded as important as its efficacy. In all four phases of drug development evaluation of adverse events is important. Recommendations for assessment of adverse events in acute and prophylactic clinical drug trials in migraine are given. Tolerability may be indirectly assessed using measures of general well-being and eight such tools are presented. Finally, recommendations for reporting of adverse events are given.
