How it works
Caffeine causes cerebral vasoconstriction and enhances absorption of analgesics. Caffeine withdrawal is itself a common headache trigger.
Only helpful for regular caffeine users. Can worsen headaches in caffeine-sensitive individuals. Avoid in the afternoon if sleep is already disrupted.
Meta-analyses confirm caffeine as an effective analgesic adjuvant. Combined with ibuprofen or paracetamol, effect size increases by approximately 40%.

“Some improvement but not as dramatic as I hoped. Might need longer to see full benefit. Still continuing.”
