FAQ
Frequently Asked Questions
Digitalis is the name of the plant genus (foxglove). Digoxin is one specific chemical compound (a cardiac glycoside) purified from Digitalis lanata. 'Digitalis' is sometimes used historically to refer to the leaf powder or other compounds like digitoxin.
Digoxin has a very narrow therapeutic window. This means the difference between a helpful dose and a toxic, dangerous dose is very small. Factors like kidney function, other medications, and age can easily push levels out of the safe range.
Symptoms include gastrointestinal issues (nausea, vomiting, diarrhoea), visual disturbances (blurred vision, yellow/green halos), confusion, and potentially dangerous heart rhythm abnormalities.
No. Abruptly stopping digoxin, especially for conditions like heart failure or atrial fibrillation, can lead to a worsening of the underlying heart condition. Any change in dosage must be done under direct medical supervision.
