Hi fergalw,
Thank you for your question and welcome to the discussion forum!
Candarsartan, brand name Atacand, can be used for migraine prevention. I've not tried this medications but do know some have good results with it. It can take up to 90 days before we see a reduction in our migraine frequency and severity as our body adjusts to new medication. Also during this time potential side effects may lessen.
Hopefully others will be along shortly to share their experiences with you. Will you keep us posted on your progress?
Nancy
