Beta Blocker not lasting full 24hrs

Posted , 6 users are following.

As per the title

I find that some days my Beta Blocker (5mg Bisoprolol) is not lasting the full 24hrs and allowing breakthrough A-FIB after around 18 - 20 hours.

Does anyone else find this?, if so what is the answer? should I up the dose with the Dr's blessing, or split the dose in two and take half morning and half night?.

or is there another answer?.

Many thanks for any help or advice as usual

    I'm also on Bisoprolol (2.5mg) and used to take it in the morning.Mmy afib episodes always started at around 3am which to me was not coincidence.. About 3 months ago I started taking it at 3pm and have not had an episode since. Maybe daily activity keeps the heart in rhythm until the next dose.

    If it was me i would do both. 3.75 morning and evening and see if that worked. It is trial and error and everyone is individual.

    Hi Andrew,  I too was getting A-Fib episodes when I was taking a lower dose of Bisoprolol. So, the GP I saw upped it to 10mg which (touch wood) has been fine for the last few years. Hope this helps, but, do get your doctor's blessing on your dosage. Good Luck.

    i agree, i think its time to speak to the Dr and get the dose and times tailored properly

    if i hadnt have visited him several times telling him each time 2.5mg wasnt working anymore then I would have never got his full attention and to agree to try 5mg.

    2,5mg worked for all of 2 weeks before i started getting more and more frequent episodes as the days wore on.

    5mg lasted about the same before it started again.

    I know the Dr isnt a mind reader or miracle worker but I just wish he'd be a bit more understanding about how damn life changing worrying and annoying A-FIB is.

    Hi Andrew,

    I also had problems with my Bisoporol, I had a word with my local pharmacist and she told me to take it in the evening which I did and have had no problems since.

    Hope you get it sorted as you say Afib can be very scary GP's and cardiac consultants wouldn't be so blaza if they had had it.
