What do I have to consider when weaning?

Beta-blockers must always be removed, i.e. slowly reduced, when weaning. The time required for this varies and depends mainly on the original dose. Often the doctor will gradually reduce the dose over about two weeks.

This cautious phasing out is very important, as otherwise the risk of cardiac arrhythmia or even a heart attack increases if the medication is interrupted abruptly. The reason for this is the so-called rebound effect. By taking beta-blockers, the number of so-called beta-receptors is increased throughout the body.

Sudden discontinuation of the beta-blockers then leads to an excessive response to the stress hormones adrenaline and noradrenaline with the above-mentioned consequences. By discontinuing the beta blockers taken as a preventive measure, a migraine attack can also be triggered.
