Average costs for Digoxin with Medicare drug coverage

Your copay and deductible costs for any prescription drug can vary depending on what coverage stage you’re in and the Medicare drug plan you have.

Deductible stage Typical copay stage
Your deductible is the amount of money you must spend on covered drugs before your Medicare drug coverage starts paying its share of costs.

In the deductible stage, you’re responsible for the full cost of your prescription drugs.

Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $480 in 2022.
After you meet your Part D deductible, you enter the initial coverage period.

During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.

Additional information

Your Digox use must be monitored closely while you take it, as it can lead to Digoxin toxicity if your levels are too high.

Tell your doctor if you experience signs or symptoms of Digoxin toxicity, which include loss of appetite, nausea, vomiting, visual changes or abnormal heart beats.

You may be at an increased risk for Digoxin toxicity if you are older or if you have a low body weight, kidney problems, low potassium, high calcium or low magnesium.

Digox is typically reserved for use after other atrial fibrillation or heart failure medications have failed. It is usually used in combination with certain other medications for adequate control of your condition.
