Global Patient Feedback for Metoprolol ( Post a comment )
Question/Comment:
Breathlessness (after walking up one flight of stairs, or a steep incline):
I take Diovan 80mg (2x), Toprol 12.5mg, Plavix 75mg and have just been put on Hydrochlorothiazide 12.5mg to further lower my BP, which gets up in the high 150's and low 160's.
I know the toprol is a low dose, but is it possible that this is the problem?
I also take Trilipix 135mg and Co-enzyme Q-10 150mg
I often have to sit down and rest (& calm my breathing) after one flight of stairs.

Question/Comment:
I've been on metoprolol since my heart attack in 2004, which was caused by a fat buildup in my arteries from Cushing's disease. In recent months, my pituitary has begun to function again, and I'm noticing lots of changes with my drugs. For example, I now have insomnia... I started leaving off the evening dose of the metoprolol and have been sleeping much better.
Any advice, comments?

Question/Comment:
I was taking 25mg metoprolol once a day and Cozaar 25mg twice a day and was having flucuating BP and so tired. I tapered myself down to only 1 metoprolol per day with my dr's ok. I now have a BP of 110/70 and my heart rate is normal and I am not as tired. I feel better and have more energy. I do have some wt. gain but am working on that. I now can walk more since I'm not so tired.

Question/Comment:
I just started Metoprolol Tartrate 25mg twice daily. The doctor is using it only for my fast resting heart rate. My blood pressure is fine. My resting pulse has gone from average of 175 to about 115. And no more heart palpatations!! I LOVE it!

Question/Comment:
in a 24 hour period I take 150mg metoprolol, 37.5/25 mg dyazide, 5mg tapazole, 160 mg diovan, 10 mg claritin, 400mg vitamin E w/folic acid, b6 & b12. My problem is most days suck because I have unsteadiness, balance is off. It is not vertigo (dizziness). Some days I walk around like a drunken sailor. My primary care doctor say it not the meds, but I disagree. Does anyone that takes these meds have this problem? I am desperate at this point.

Member Answer/Reply:
I am not a medical professional , but have been on metoprolol for years for high bP and I have asthma. I take only 25mg once daily.
Your other meds sound a bit much, i.e., sounds like you are over medicated and I would find a good cardiologist for complete evalution.
I repeat. Go to a well known highly recommended cardiologist and discuss all of your meds. with him/her. Good luck!

iGuard Answer/Reply:
You are on several medications for blood pressure, metoprolol, Dyazide, and Diovan. If your blood pressure is too low, you could be experiencing some unsteadiness. Ask your doctor about monitoring your blood pressure more regularly, as with a home blood pressure machine to see if there is a correlation between the unsteadiness and dips in your blood pressure. Your doses may need to be adjusted if your blood pressure is too low when you are not in the doctor's office.
