Why it happens
Opposing pharmacodynamic effects on serum potassium (beta-2 driven intracellular shift versus anti-mineralocorticoid potassium retention).
What to do
Check serum potassium during dobutamine infusion in patients taking drospirenone, particularly if renal impairment or other potassium-raising drugs are present.
