Digoxin
Digoxin
A digoxin test is used to assess the levels of digoxin present in the bloodstream. Digoxin is a medication utilized in the treatment of heart failure and irregular heart rhythms. Heart failure results in a decrease in the heart's ability to efficiently circulate blood.
This test may be recommended by your healthcare provider in order to monitor digoxin levels. Monitoring of digoxin levels is essential due to its narrow safety range. Inadequate levels may lead to the recurrence of heart failure symptoms, while excessive levels can result in toxicity. Dosage adjustments may be made according to measured levels.
Symptoms caused by digoxin toxicity
Confusion
Dizziness
Fast heartbeat
Blurred or double vision
Nausea or vomiting
Diarrhea
