What can be done to get back energy while on beta blockers?

[Neo3]

I am very tired since I take bisoprolol (called Zebeta in other parts of the world, if I'm right).

Should I take magnesium, or Q10, or maybe vitamin B complex? Which could help? I could sleep all day, and also get tired very easily.

thanks!

It's interesting! Thanks for the info!

I'm on a low dose, 2.5 mg in the morning. Could the pill cause the fatigue, or may be more the summed effect of the pill, plus iron deficiency?

Bisoprolol is a very common beta blocker.  It's been on the market for nearly 25 years.  You didn't say what dose you're on, but with like any beta blocker.  Increased dose levels can really slow you down.  I am on Metoprolol, and have been so for over 10 years.  The dosages between the different drugs are not equivalent, but I mention it for reference.  I started daily doses at 50mg, and went as high as 200mg.  At that level, I could barely operate.  I felt like a zombie, and simple tasks left me with a heavy feeling in my chest.  We backed it off to 100mg, and I felt a lot better.  After my ablation, I had it reduced further to 75mg.  At this level, physical exertion is almost normal provided I warm up ahead of time, and get my heart rate up to operational speed.  I find it slow to respond, so warming up a bit will slowly get it up to speed.

I wanted to mention this to you as well:
Bisoprolol has a pretty long half life.  It's around 10 hours.  What this means is that 10 hours after taking it, half the drug remains in your blood.  Do the math, and you'll see that in 24 hours, a quantity of the drug remains in your blood, when you take another dose.  As you take your daily dose, the level of the drug continues to build in your blood.  (This is where my knowledge falls off)  This could be a good thing, and might be necessary to build up a therapeutic level.  But I'll also thinking that over time, perhaps months, the level of the drug becomes higher than what was intended for you.  I notice this with my beta blocker.  After several months of taking it, I will begin to feel sluggish and a little off my game.  So what I do is to stop taking it for a day or two, and let my body clear the suspected overload.  Then I hop back on it with my regular dose.  I'm not suggesting to do this on your own, but consult with a physician if you feel a bit off your game.

Thank you for your reply, pacperson!!

I have been taking it for 1,5 years now. I take 2.5 mg of bisoprolol.
Still, very tired most of the time.

It might be bcause of my low iron levels, or maybe the depleeted nutrients it can cause: I read q10, maybe magnesium.

I am on Carvedilol, 6.125mg 4X a day. I think it's a small dosage, but exercising helps keep my energy up. Vitamine B12 is worth trying too, I take it. Also, my cardiologist says most people will adapt to beta blockers and not feel as tired after awhile. How long have you been taking it ?
