Hi everyone, I’ve been on metoprolol Succinate ER for 8 year 25 mg no problems. So recently my blood pressure went up super high so they doubled my metoprolol to 50mg . It brought down my blood pressure but then my asthma started acting up. At first I thought it was a coincidence because I always get sick at this time of the year but now 1 1/2 after the other issue am sick again. So now I am beginning to think that maybe the Dr. needs to change my BP medicine to a calcium channel blocker. Has anyone experienced this type of problem and if so did it help you with your asthma ? Hope everybody is doing well , Happy Holidays.
