The European Headache Federation (EHF) defines both effective treatment for acute migraine and triptan failure in patients experiencing attacks.
Why this matters
Triptan use for acute therapy aims to reverse or stop the progression of a headache that has started. Previous studies present inconsistent findings on triptan use, hence a clear definition on triptan failure in clinical practice is necessary.
Standardized definitions may help inform decision-making on treatment and further support the design of future clinical trials to understand the complexities of migraine treatment.
