Digoxin is a medicine licensed to treat congestive heart failure and atrial fibrillation. This prescription drug works by blocking a certain enzyme in the body, allowing the heart to be more efficient at pumping blood throughout the body. It comes in the form of a tablet, an injection, and an oral liquid (elixir). Potential side effects include nausea, headaches, and dizziness.
