What it’s for & How to take

Digoxin is used to control abnormal heartbeats and to treat heart failure. This medication works by helping your heart beat stronger and more regular.

Digoxin is usually taken once daily. This medication may be taken with or without food; however, foods that are high in fiber may block digoxin from working. Wait at least 2 hours before or after taking this medication before you eat any food high in fiber.
