I’ve been asked to discuss the relationship between Digoxin levels and potassium…so I will. Digoxin toxicity was discussed earlier this week, and obviously the kidney plays a big role in both digoxin levels and potassium homeostasis. Individuals with low potassium may be more susceptible to possible digoxin toxicity i.e. they may experience toxicity at digoxin levels lower than the usually accepted upper limit of 2–per Lexicomp. What can affect potassium levels? In many cases, digoxin is used in the management of congestive heart failure. In congestive heart failure, there is a high utilization of diuretics (especially loops) which can significantly reduce potassium levels and potentially increase the risk of digoxin toxicity as described above. Close monitoring of renal function and potassium levels are very important in appropriate use of digoxin.

Thank you for a great review!
so low k increases chance for digoxin toxicity, does digoxin have any effect on potassium levels itself?
Thank you so much for this great information.
Do we need to supplement potassium prophylactically on low doses with digoxin therapy?
I would like to congratulate Dr. Eric for helping pharmacist and other health care professionals in improving medication and disease knowledge.
I am teaching Pharmacotherapy courses in Calgary, Canada. I would like to talk to Dr. Eric on phone if possible.

Thanks so much Syed, why don’t you shoot me an email at [email protected] with what you are interested in chatting about? Thanks!
Why does low k make dig toxicity more likely at lower levelslevels
