Digoxin (Lanoxin) Test

Monitoring digoxin levels is essential because it has a narrow therapeutic range, meaning the difference between an effective and toxic dose is small. Regular testing ensures that your dose is safe and effective.

Symptoms of digoxin toxicity can include nausea, vomiting, diarrhea, confusion, visual changes (such as yellow or green vision), and irregular heartbeat.

A healthcare professional will take a blood sample, usually from a vein in the arm. This sample is then sent to a lab where the level of digoxin in the blood is measured.

The typical therapeutic range for digoxin levels is between 0.5 to 2.0 ng/mL. However, the optimal range may vary for different individuals.

Kidney function, age, body size, drug interactions, and other medical conditions can affect how the body handles digoxin, and thus affect the drug levels.

The frequency of testing should be determined by your doctor, but levels are often checked when the medication is first started, if there is any change in dose, or if you experience symptoms of toxicity.

If your digoxin level is outside the therapeutic range, your doctor may adjust your dose or make changes to your medication regimen. It is important not to make any changes without consulting your healthcare provider.
