Timing of the digoxin blood test is important. The sample should be collected at least 6-8 hours after you last took your digoxin. Very often, the blood sample will be collected just before the next dose is to be taken.
What labs do you monitor for digoxin?
Digoxin is primarily cleared from the body by the kidneys. If you have kidney problems, your healthcare provider may want to monitor kidney function and blood potassium levels since kidney dysfunction and low levels of potassium can result in symptoms of digoxin toxicity.
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.
What is the normal range of digoxin?
Therapeutic levels of digoxin are 0.8-2.0 ng/mL. The toxic level is >2.4 ng/mL.
What are the early signs of digoxin toxicity?
Some early warning signs of overdose are confusion, loss of appetite, nausea, vomiting, diarrhea, or vision problems. Other signs of overdose are changes in the rate or rhythm of the heartbeat (becoming irregular or slow), palpitations (feeling of pounding in the chest), or fainting.
How often should digoxin levels be done?
Ten days was chosen as appropriate timing to measure digoxin levels after initiation of therapy or dosage adjustment because steady state is reached in patients after 4 to 5 elimination half-lives of digoxin.
How do you know digoxin is working?

If the level of digoxin in your system is too low, you may experience the symptoms of heart failure. These symptoms include: fatigue. shortness of breath. edema, or swelling in your hands and feet.
What is digoxin level for 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 the normal level of digoxin?
What does it mean when your digoxin level is low?

What are the normal blood levels for digoxin?
Patients may exhibit signs of toxicity above 2.0 µg/L but the incidence of toxicity increases markedly above 3.0 µg/L
How often should digoxin levels be checked?
When should digoxin levels be rechecked? After oral administration, there is an early rise in serumconcentration. Equilibration of serumand tissue levelsoccurs at approximately 6 to 8 hours. For this reason, blood specimens for digoxinanalysis shouldbe drawn at least 6 to 8 hours after drug administration. Digoxinis excreted primarily in the urine.
What happens if digoxin levels are too high? Digoxin toxicity can emerge during long-term therapy as well as after an overdose.
