Кратко
Furosemide can cause hypokalemia and hypomagnesemia, which markedly increase myocardial sensitivity to digoxin and the risk of arrhythmias even at normal serum digoxin concentrations. Volume depletion and reduced renal function from diuresis may also reduce digoxin clearance. The combination is very common in heart failure, so electrolyte monitoring is essential.
Что означает это взаимодействие простыми словами
Digoxin and Furosemide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Digoxin belongs to Cardiovascular; Furosemide belongs to Cardiovascular.
Почему это происходит
Pharmacodynamic: loop diuretic-induced potassium and magnesium depletion potentiates digoxin's effects on cardiac automaticity and conduction. Pharmacokinetic: volume depletion or acute kidney injury can reduce renal digoxin clearance.
Что делать
Check potassium, magnesium and creatinine at baseline, after starting or changing the furosemide dose, and periodically thereafter. Correct deficits, using potassium supplements, a potassium-sparing diuretic, an ACE inhibitor or an MRA where appropriate.

Частые вопросы
Can I take Digoxin with Furosemide?
MediHelp rates the interaction as major. Digoxin and Furosemide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for. Furosemide can cause hypokalemia and hypomagnesemia, which markedly increase myocardial sensitivity to digoxin and the risk of arrhythmias even at normal serum digoxin concentrations. Volume depletion and reduced renal function from diuresis may also reduce digoxin clearance. The combination is very common in heart failure, so electrolyte monitoring is essential.
How serious is the interaction between Digoxin and Furosemide?
MediHelp rates it major, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: Check potassium, magnesium and creatinine at baseline, after starting or changing the furosemide dose, and periodically thereafter. Correct deficits, using potassium supplements, a potassium-sparing diuretic, an ACE inhibitor or an MRA where appropriate.
