I do. I take 100mg of Metoprolol every day. I take Diltiazem when I have an episode of afib. I take it every 4 hours until back in sinus rhythm

My medical chart says to never prescribe diltiazem and metoprolol together for me. It was during a time when I was having side effects from various meds to control my arrythmia. The metoprolol was still in my system . The diltiazem set off an irregular heart beat that freaked me out. Anyway in the end, I stayed on metoprolol and no more problems. I imagine each individual case may be different.

Used to for about 1 year. Went off both too many side effects!!!

I do. My Dr. at Mayo put me on the two. So far so good.
