Longtime chronic migraineur here. I recently started a new prophylactic (1 month ago), Norvasc, drug name Amlodopine, which is a calcium channel blocker. I have noticed that since starting it my cognitive abilities have gone down the drain. I even find it hard to type this sentence coherently, spell things, I get words twisted when I’m saying them. I make a lot of typos and find it hard to concentrate and get work done. I feel like I have brain fatigue. I got this on Topamax a few years back. I can’t find anything in Norvasc side effects that relate to these sypmtoms, so I’m wondering if anyone else on calcium channel blockers has experienced this.
Maybe its just a progression of the disease. I do have white matter lesions on my brain.
Thanks for any input!
