Omeprazole can cause _____. Therefore it is important to monitor _____ levels before and after starting therapy, particularly in this case when the patient has an underlying arrhythmia and is taking digoxin. Hypomagnesaemia can lead to an increased risk of arrhythmia and digoxin toxicity.

Measurement of serum-magnesium concentrations should be considered before and during prolonged treatment with a proton pump inhibitor, especially when used with other drugs that cause hypomagnesaemia or with digoxin.
