My husband has been on metoprolol for 2 yrs. His blood pressure was around 145/95. Otherwise he was very healthy. Now he is 50 lbs overweight, borderline diabetic, and his liver enzymes are double and his triglycerides are triple. His doctor told us she wants to send him to a liver specialist. I have been doing some research of my own and now feel its the meds. He will be going of this starting today and I will let you know how his next blood work is. Please have your liver enzymes tested. Don't want this to happen to anyone else.
