Why this happens
Both magnesium and bisoprolol (a beta-blocker) can slow down the electrical signals in your heart and relax your blood vessels. When used together, these effects can add up, making your heart beat too slowly or lowering your blood pressure more than intended.
What you should do
You should consult your doctor before taking magnesium supplements with bisoprolol. If your doctor approves the combination, monitor your pulse and blood pressure regularly. Seek medical advice if you feel unusually tired, dizzy, or if you notice your heart rate is very slow. To avoid any potential issues with how the medicine is absorbed, it is also sensible to space the doses apart by at least 2 hours.

Taking esomeprazole for a long time (usually more than three months) can lower the levels of magnesium in your blood. This can lead to symptoms like tiredness, muscle spasms, or an irregular heartbeat. Additionally, if you take magnesium as an antacid or supplement at the same time as esomeprazole, it might slightly interfere with how well the medicine is absorbed.
