Patients should be instructed to report any signs of digoxin toxicity, such as cardiac arrhythmias or hypokalemia. Patients who are at risk for hyperkalemia , including those with renal insufficiency , should pay attention to their potassium levels and discontinue digoxin if they develop hyperkalemia . Digoxin can also interact with other drugs that increase serum potassium concentrations, e.g., sodium-channel blockers (e.g., diltiazem), angiotensin II receptor antagonists (e.g., candesartan) , aliskiren, amlodipine, losartan, verapamil or darunavir. The risks of drug interactions are compounded by the fact that patients very often have concomitant medications that may raise their serum potassium concentration. Therefore it is important to check serum potassium regularly after starting this medication and adjust dosages accordingly when necessary.
