How does hypokalemia affect digoxin

WebLevels less than 1.5 nanograms/mL in the absence of hypokalaemia indicate that digoxin toxicity is unlikely. Levels greater than 3.0 nanograms/mL indicate that digoxin toxicity is likely. With levels between 1.5 nanograms/mL and 3.0 nanograms/mL, digoxin toxicity should be considered a possibility. WebDigoxin toxicity is also worsened by hypokalemia. Because digoxin binds to the K + site of the Na + /K + -ATPase pump, low serum potassium levels increase the risk of digoxin toxicity. Conversely, hyperkalemia diminishes digoxin's effectiveness.
