What is goal digoxin level in AFib?

The target serum digoxin concentration should be 0.5 to 1.0 ng per mL (0.6 to 1.3 nmol per L). Digoxin is not recommended for the treatment of diastolic heart failure. Digoxin should be used only as a second-line therapy for controlling the heart rates of patients with atrial fibrillation associated with heart failure.

What is the therapeutic level for digoxin?

Therapeutic levels of digoxin are 0.8-2.0 ng/mL. The toxic level is >2.4 ng/mL.

How does digoxin affect atrial fibrillation?

Digoxin in atrial fibrillation In patients with AF, the primary effect of digoxin is slowing down atrioventricular (AV) conduction, leading to a reduction in ventricular response at rest, but much less so during exercise.

What happens if digoxin levels are too high?

Digoxin toxicity can emerge during long-term therapy as well as after an overdose. It can occur even when the serum digoxin concentration is within the therapeutic range. Toxicity causes anorexia, nausea, vomiting and neurological symptoms. It can also trigger fatal arrhythmias.

When should a digoxin level be drawn?

– When monitoring digoxin therapy, drug levels should be drawn when the patient is at steady-state (ie: 4-5 half lives have passed since the last dose change or since drug initiation). – When monitoring digoxin, blood levels should be drawn no sooner than 6 hours after the most recent dose.

What is the therapeutic range for digoxin in heart failure?

Digoxin serum concentrations greater than 1.2 ng/mL lead to an increased risk of mortality in patients with heart failure. Thus, the therapeutic range of digoxin concentration currently recommended for the treatment of heart failure is 0.5 to 0.9 ng/mL.

What is digoxin level for heart failure?

Digoxin is recommended for symptomatic patients with stage C or D heart failure. The target serum digoxin concentration should be 0.5 to 1.0 ng per mL (0.6 to 1.3 nmol per L).

How much is too much digoxin?

Digoxin levels of less than 0.5 ng/mL have been associated with reduced efficacy, while levels above 2 ng/mL have been associated with toxicity without increased benefit. However, digoxin levels should always be interpreted taking into account what effects the drug is having and any symptoms of toxicity.

When should I check my digoxin level?

After oral administration, there is an early rise in serum concentration. Equilibration of serum and tissue levels occurs at approximately 6 to 8 hours. For this reason, blood specimens for digoxin analysis should be drawn at least 6 to 8 hours after drug administration. Digoxin is excreted primarily in the urine.

Do not give digoxin if heart rate is below what?

Guidelines for taking digoxin Check your pulse before you take your digoxin. If your pulse is under 60 beats per minute, wait 5 minutes. Then check your pulse again. If it’s still under 60, call your healthcare provider.

What is a therapeutic digoxin level?

Therapeutic levels of digoxin are 0.8-2.0 ng/mL. The toxic level is >2.4 ng/mL. [ 3] The toxic range for digoxin is greater than 2.5 ng/mL. About 10% of patients may show toxicities at levels less than 2 ng/mL (particularly in hypokalemia, hypomagnesemia, hypoxia, heart disease, and hypercalcemia

How does digoxin help AFIB?

a serious heart condition such as “sick sinus syndrome” or “AV block” (unless you have a pacemaker );

  • a heart attack;
  • slow heartbeats that have caused you to faint;
  • Wolff-Parkinson-White Syndrome (sudden fast heartbeats);
  • kidney disease;
  • an electrolyte imbalance (such as low levels of calcium,potassium,or magnesium in your blood);

    • What does digoxin do for AFIB?

    Analytical problems in the assay procedure.

  • Inappropriate serum sampling time.
  • Administration of a digitalis glycoside other than digoxin
  • Conditions (described in WARNINGS and PRECAUTIONS) causing an alteration in the sensitivity of the patient to digoxin.

    • Is digoxin used for AFIB?

    Digoxin remains one of the most frequently prescribed drugs in the management of atrial fibrillation. The main indications for digoxin in atrial fibrillation are restoration of sinus rhythm, prevention of recurrence and slowing of the ventricular rate. However, none of these effects of digoxin have been confirmed in placebo controlled studies.
