Had my beta blocker doseage doubled and feel awful: how long will this last?

[FoxesOnSocks]

Started the new dosage on Friday, was okay yesterday but today feel awful. Very lightheaded constantly.

Started beta blockers a long time ago and whilst I recall I felt bad - lightheaded and palpitations I can't recall for how long.

Anyone have experience?

Started Thursday, not Friday

I'm just bumping this for you.

I took beta blockers once, a long time ago and they took a while to kick in (about three weeks) but I didn't feel any side effects at all before then.

Sorry not to be more help.

Three weeks!!

Oh no!!

Why have you had them increased? This will make a difference as to whether you should persevere with the higher dose or not. If they are making you light headed or dizzy then they are likely reducing your blood pressure and/or pulse a bit too much and you you should see your GP as it may be better to reduce the dose again.

I've an aortic coarctation and my 'higher side' is a bit higher than the cardiologist was happy with.

Though my 'lower side's wasn't high.

My GP won't change my dosage as it's the cardiologist that prescribed.

Which ones are they? I was given some after a failed ablation and i felt dizzy and sick constantly so I changed to different ones.

Bisop 5mg

Bisop 2.5mg previously

Don't stop them but get your blood pressure and heart rate checked - maybe your GP could try and speak to your cardiologist on Monday? Or is there a specialist nurse who works with your cardiologist you could call tomorrow?

So an adjustment period isn't to be expected?

I'm resisted to go to GP as I highly suspect I'll be giving him a heap of money (no NHS here) for him to say he can't make the decision

Yes there's a nurse I can call.

Yes there can be an adjustment period but it's important to get things checked out if you are having unpleasant side effects (which you are). Call the nurse - she can advise you best and chat to the cardiologist if necessary.
