Description
Indications
Digoxin is used to treat heart failure, typically in combination with other medications. It is also used to treat certain types of irregular heartbeat, such as chronic atrial fibrillation. Digoxin belongs to a class of medications called cardiac glycosides. It works by influencing certain minerals (sodium and potassium) inside heart cells, reducing strain on the heart and helping it maintain a normal, steady, and strong heartbeat.
Uses and Dosage
Take this medication by mouth with or without food, usually once daily or as directed by your doctor.
If you are using the liquid form, carefully measure the dose using the dropper provided by the manufacturer. Avoid using a household spoon, as it may not provide the correct dose.
Your body may not absorb this drug as well if you consume high-fiber foods or take certain medications. Take this medication at least 2 hours before or after eating high-fiber foods (such as bran). If you are also taking cholestyramine, colestipol, or psyllium, wait at least 2 hours after taking your digoxin dose before using any of these products. For antacids, kaolin-pectin, milk of magnesia, metoclopramide, sulfasalazine, or aminosalicylic acid, take them as far apart from your digoxin dose as possible. Consult your pharmacist if you are unsure when to take your medications.
The dosage of this medication is based on your medical condition, age, body weight, laboratory tests, and response to treatment.

FAQ
Does Lanoxin lower heart rate?
Yes, Lanoxin can slow heart rate by slowing the electrical activity in the heart. This is how the medication works to treat atrial fibrillation (AFib).
Is Lanoxin a beta blocker?
No, Lanoxin isn’t a beta blocker. Both Lanoxin and beta blockers both lower heart rate, but they do so in different ways. It’s common for people with heart failure or atrial fibrillation to take both Lanoxin and a beta blocker together.
