What is LANOXIN Injection

LANOXIN Injection belongs to a group of medicines known as cardiac glycosides. They work by slowing down the rate while increasing the force of your heart when it beats.

It is used to treat certain heart problems, such as:

Chronic Heart failure
Heart failure is when your heart can’t pump strongly enough to supply blood needed throughout the whole body. It is not the same as a heart attack and does not mean that your heart stops.

Certain type of irregular heart beats
Irregular heart rhythms caused by an electrical problem in the upper chamber of your heart. They cause your heart to beat too fast or in an uneven way.

Ask your doctor if you have any questions about why LANOXIN Injection has been prescribed for you. Your doctor may have prescribed it for another reason.

There is no evidence that LANOXIN Injection is addictive.
