Amlodipine
"Just as the above, my life has been changed as a result of starting on Amlodipine. I was prescribed it for my hypertension, and my migraines have completely disappeared. I suffered migraine three days a week. I mentioned this to my GP and he told me this makes perfect sense. Migraine, I'm told, is a consequence of blood vessels in the head being in spasm and Amlodipine has a 'stabilizing' effect on these blood vessels."
