What this trial studies

Adults diagnosed with migraine by ICHD-3 criteria are given a 200 mg caffeine tablet extracted from green tea during an acute migraine attack and pain severity is measured using a visual analogue scale (VAS) before and after treatment. The protocol allows common acute migraine medications such as triptans, NSAIDs, or paracetamol as listed interventions and records responses alongside caffeine use. The study is conducted in the headache and neurology outpatient clinics at Ain Shams University and targets real-world clinic patients. The main outcome is change in VAS pain score following the caffeine dose.

Who should consider this trial

Good fit: Adults with episodic or chronic migraine, with or without aura, diagnosed according to ICHD-3 who can attend the Ain Shams University outpatient clinic are eligible.

Not a fit: Patients with cardiac dysrhythmia, hypertension, ischemic heart disease, active peptic ulcer disease, inflammatory bowel disease, certain psychiatric disorders, pregnancy or breastfeeding, renal or hepatic failure, sleep disorders, substance abuse, or those with secondary headache causes are excluded and unlikely to be appropriate or benefit from this intervention.

Why it matters

Potential benefit: If effective, a single 200 mg caffeine tablet could offer a simple, low-cost option to reduce pain during acute migraine attacks.

How similar studies have performed: Prior research has shown that caffeine can enhance analgesic effects when combined with pain relievers, but using a standalone 200 mg caffeine tablet from green tea to abort acute migraine is less well studied.
