A patient is being given Digoxin to treat heart failure. Which of the ff. is a usual adult daily dosage of digoxin (Lanoxin)?
Correct Answer: C
Rationale: The usual adult daily dosage of digoxin (Lanoxin) for the treatment of heart failure typically ranges from 0.125 mg to 0.25 mg. The maintenance dose is specific to each individual patient's needs and is adjusted based on factors such as age, weight, renal function, and the presence of other medical conditions. The dosage prescribed should be carefully determined by a healthcare provider to ensure optimal therapeutic effects and minimize the risk of side effects associated with digoxin. Dosages higher than 0.25 mg are usually not recommended due to the narrow therapeutic index of digoxin. It is essential for patients taking digoxin to have their drug levels monitored regularly to prevent toxicity.
