How do you monitor digoxin toxicity?
To determine the total body load of digoxin (in milligrams) for patients experiencing toxicity as a result of chronic ingestion of digoxin, one should multiply the serum digoxin level (in ng/mL) by the volume of distribution of digoxin (7.3 L/kg) by the patient’s ideal body weight (in kg) and divide by 1,000.
What is the prototype for digoxin?

What are two 2 contraindications for the use of digoxin?
Heart Condition Contraindications Having myocarditis, infection in the heart muscle, previous heart attack, and ventricular fibrillation, quivering or shaking of the lower chambers of the heart, would prevent a person from being able to take digoxin.
What does digoxin do to potassium?
Digoxin toxicity causes hyperkalemia, or high potassium. The sodium/potassium ATPase pump normally causes sodium to leave cells and potassium to enter cells. Blocking this mechanism results in higher serum potassium levels.
How do you load digoxin?
How to load digoxin
- IV. Digoxin loading dose IV: 500mcg; followed by 250mcg 6 hours later and a further 250mcg 6 hours after that.
- PO. Digoxin loading oral: 500-750mcg 2 doses 6 hours apart (max 1500mcg in 24 hours)
What is the antidote to digoxin?

What does digoxin do to the heart?

Can you drink orange juice while taking digoxin?

As per ACCF/AHA guidelines, a loading dose to initiate digoxin therapy in patients with heart failure is not necessary. 0.125-0.25 mg orally/IV once/day; higher doses including 0.375-0.5 mg/day rarely needed. Use lower end of dosing (0.125 mg/day) in patients with impaired renal function or low lean body mass.
What are the effects of digitalis on an EKG?
The use of digitalis generates changes in the electrocardiogram at therapeutic doses, especially at the level of the ST segment and the T wave. It also decreases heart rate , and in the case of toxicity, it can generate a great variety of arrhythmias .
How to monitor digoxin levels?
Digoxin levels must be monitored because the drug has a narrow safety range. If the level in the blood is too low, symptoms may recur. If the level is too high, toxicity may occur. Digoxin dosage may be adjusted based on levels measured. A blood sample is obtained by inserting a needle into a vein in the arm.
