Amlodipine
"Suffered migraines for many years getting them once a week or more, Doctor prescribed Imigran, at onset, not much use when you are sick with them, anyway, I was told I had hypertension, prescribed Amlodpine, 5 MG initially and then 10MG! Almost immediately the migraine were gone, I changed blood pressure medication once on the advice of my Doctor, the migraines came back with two days, back on Amlodipine for me, no more migraine, I went to the pharmacist who explained why it works in this way, I would recommend. Miracle stuff."
