Because these effects resemble the clinical condition for which the drug is administered (82), it is recommended that the serum concentration of digoxin or digitoxin be monitored to determine if the drug dose needs to be increased (if the patient is subtherapeutic) or if a possible overdose needs to be treated (if the serum concentration of the drug is above the therapeutic range).
