I have had issues with my BP for the past year. I took meds like clock work. Because it scared me. I went for a few months of good all the time. Then a few months of high BP and it freaked me out. Finally after a few er visits. (I) figured it out. The pharmacy would change the manufacture. I talked to my dr and she put. Note on my file that I could only have this certain manufacturer. And walla. Was great. Then like 9 months later I was getting sick again. Went. Few days and then checked my new prescription and it changed again. I called pharmacy and they refilled it and all has been good since. Now I got a lot of slack from Pharmacy that the prescription was the same. I said no. They said yes. I said then why is one round and the other is oval. Right there they r different. Needless to say I h a v e’d Spence had a stent put in I feel better except out of breath. I have done some research and found that the metoprolol is famous for making some out of breath. I have stopped it and bp went from 157/80 to o 113/56. Crazy. But going to give it a few days to see if my breathing improves and bp stays lower. Try and keep track of the manufacturers on your meds. That could be some of your issues. Good luck to all
