Bisoprolol 5mg not lasting full 24hrs

Posted , 5 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


PS: I have posted this Question in both this Forum & the A-FIB Forum to hopefully get as many relevant tips and advice as possible, I hope this is ok.

    You should see your GP and go with their advice. Sorry but if it was me a medical opinion and knowledge is more valuable to me than fellow sufferers of a condition or who take the same medication.

    As others said, you should ask your doc.

    My doc told me if I will need a higher dose, that I can take a full dose in the morning and half a dose in the evening.

    In general, people should take Beta blockers in the morning since they will protect you the most throughout the day when you have more activity and higher chances to get an episode.

    If you take a drug only at evening, then it will protect you mostly during a sleep and you will get a weaker protection during the day.

    So, ask your doc about options, like half a dose in the morning, half a dose in the evening.

    Or a full dose in the morning and half a dose in the evening.

    Or just dose and a half or double dose in the morning.

    Good luck
