If youâre receiving treatment for heart failure, the normal level of digoxin is between 0.5 and 2.0 nanograms of medication per milliliter of blood (ng/ml). If youâre being treated for a heart arrhythmia, the normal level of the drug is between 1.5 and 2.5 ng/ml.
For heart rate control (atrial fibrillation), plasma levels are less defined and are generally titrated to a goal heart rate. Typically, digoxin levels are considered therapeutic for heart rate control between 0.5 and 2.0 ng/ml (or 0.6 and 2.6 nmol/l). In suspected toxicity or ineffectiveness, digoxin levels should be monitored. Plasma potassium levels also need to be closely controlled (see side effects below).
