Metoprolol Tartrate only has a half life of 3-7 hours. So basically, after 3-7 hours you have just 12mg in your blood, then after 6-14 hours 5-6mg which will then slow down in effect. I would ask your DOC if you can split the dosage to
twice a day, or change to another type of medication. I had the same issue as you for years, trying to balance my meds. Finally, we now have the medication to exactly the right amounts. Each morning I now take 2.5mg of Bisoprolol (powerful substitute for your metoprolol) and a 2.5mg of Ramipril (blood pressure meds). I repeat the same procedure in the evening and everything seems stable. If you do decide to go the same route as me, I would recommend starting on 1.25mg of Bisoprolol twice daily because it is powerful. I went to 5mg once and ended up in hospital with very low pressure and pulse and it took 4 days to get everything back to normal again. 1.25mg is a good starting point and definitely will not affect your pressure or pulse to become dangerous.
You may need a different drug, like Coreg. Your fast heart beat is compensating, in my uneducated opinion. I struggle with heart beat, suddenly became between 100-150 from about 70 bpm, and it was trying to get blood to the kidneys and other organs. I developed A-Fib, where the heart quivers, doesn't really beat. I'd ask you doctor about A-Fib. In my case it led to a 10 night hospital visit when my kidneys failed. I'm back to normal, but your heart will defeat drugs if it needs oxygen to the organs. Keep us informed.
Hi,
I take this drug for high BP, but I have the slow release kind. Its called metoprolol succinate. I take 25 mg in the morning. Maybe you could ask your doctor to prescribe this?
