migraine prevention
"I have been having daily migraines with aura for many years. I tried different things until I was prescribed calcium channel blockers.I  tried first amilodipine with encouraging results at first, but then having severe side effects. So switched to verapamil, where the positive impact on the migraines is a bit less pronounced, but I am practically free of side effects. it didn't solve my problem, but I can feel a significant improvement."
