Why have I been prescribed Lanoxin?

Lanoxin (Digoxin) is a medicine which is used in heart failure and heart rhythm disorders.

How does it work?

  • Digoxin increases the force of the heart's contraction.

When and how do I take it?

Lanoxin is usually taken once daily but your dose will be tailored to suit you.
