For animals with congestive heartfailure, digoxin is used to help the heart beat more strongly and move blood through the body better. Digoxin is also used to treat certain types of heartrhythm disturbances as it can make the heart beat slower. Digoxin is used less now than in the past because it can be toxic if too much is in the body. There are now other treatments available for heartfailure. There were veterinary digoxin products in the past, but they are no longer marketed in the US. The FDA has approved drug products for use in humans, but they are not officially approved for use in animals in the US. The FDA allows
veterinarians to prescribe products containing this drug in different species or for other conditions in certain situations. You and your veterinarian can discuss why this drug is the most appropriate choice.
