Summary
Amphotericin B commonly causes hypokalemia and hypomagnesemia, which sensitize the myocardium to digoxin. This increases the risk of digoxin toxicity and arrhythmias even at normal serum levels.
What this interaction means in plain words
Amphotericin b deoxycholate and Digoxin 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.
Why it happens
Amphotericin-induced renal potassium and magnesium wasting produces additive pharmacodynamic enhancement of digoxin toxicity.
What to do
Monitor and correct serum potassium and magnesium regularly. Check digoxin levels and ECG, and consider a digoxin dose reduction if electrolyte disturbances persist.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
