Digoxin Coupons & Prices

Looking for a digoxin coupon? Digoxin is the generic form of Lanoxin, a cardiac glycoside used to treat mild to moderate heart failure and to help control the heart rate in chronic atrial fibrillation. The generic tablets are already one of the lower-cost heart medicines, but the cash price still swings a surprising amount from one pharmacy counter to the next, even inside the same ZIP code. Rx.com compares cash prices at more than 60,000 pharmacies and gives you a free discount coupon you can hand to the pharmacist. Enter your ZIP above to see today's digoxin price near you.

What is digoxin and how does it work?

Digoxin is a cardiac glycoside (a digitalis glycoside). It works in two ways: it makes the heart muscle squeeze more forcefully by blocking the sodium-potassium ATPase pump, and it slows conduction through the AV node, which slows down a fast heart rate. FDA-approved uses, per the Lanoxin label, are treatment of mild to moderate heart failure in adults (where it improves exercise capacity and reduces heart-failure hospitalizations, usually added on top of standard therapy such as diuretics, ACE inhibitors or ARBs, and beta-blockers), increasing heart-muscle contractility in children with heart failure, and controlling the ventricular rate in adults with chronic atrial fibrillation.

It is important to know what digoxin does not do. It does not restore a normal heart rhythm, and it has not been shown to help people live longer. In atrial fibrillation it is generally a second-line rate-control choice behind beta-blockers and non-dihydropyridine calcium channel blockers, and it is often favored when someone also has heart failure or low blood pressure. Digoxin comes as tablets, an oral solution, and injectable and pediatric elixir forms. Because it is cleared by the kidneys, doses are lowered in kidney impairment and in older adults.

Digoxin cost without insurance, and how a coupon helps

Digoxin is available as an FDA-approved generic, and generics of long-established heart medicines are usually inexpensive compared with brand-name drugs. That said, "inexpensive" is not the same as "the same everywhere." Cash prices for the exact same strength and quantity of digoxin can differ widely between a big chain, a grocery-store pharmacy, and an independent down the street, because each pharmacy sets its own cash price. That is precisely why comparing before you fill is worth the two minutes.

There is no manufacturer savings card for generic digoxin. What there is instead: the free Rx.com discount coupon, which is a cash-price program you can use with or without insurance (it is not insurance itself). Enter your ZIP code above, pick your strength and quantity, and you will see today's price at pharmacies near you along with a coupon to show the pharmacist. If you take digoxin long term, it is also worth asking your pharmacy about a 90-day supply, and asking your prescriber whether that is appropriate for you. Prices change, so it is worth re-checking before each refill.

Digoxin vs. Lanoxin and other heart medicines

Lanoxin is the brand name; digoxin is the same active ingredient in generic form, and the generic is substitutable at the pharmacy. Unless you have a specific reason to use the brand, the generic is the usual way to keep the cost down. Digoxin was also sold historically under names such as Digitek and Digox.

Digoxin is rarely used by itself. Depending on the diagnosis, it is often taken alongside, or considered against, other heart medicines:

• Furosemide — a loop diuretic commonly used with digoxin in heart failure to remove excess fluid. It can lower potassium, which raises the risk of digoxin toxicity, so potassium is watched.
• Metoprolol and carvedilol — beta-blockers that are standard therapy in heart failure and are generally first-line for rate control in atrial fibrillation.
• Diltiazem — a non-dihydropyridine calcium channel blocker also used for rate control; note that verapamil, in the same class, raises digoxin levels.
• Amiodarone — an antiarrhythmic that, unlike digoxin, is aimed at rhythm. It also significantly raises digoxin blood levels, so the digoxin dose is usually reduced when the two are combined.

Only your prescriber can decide which of these is right for you. Never switch or stop a heart medicine on your own.

Digoxin safety: the narrow therapeutic index

Digoxin has no FDA boxed warning, but it does have a narrow therapeutic index: the helpful dose and the toxic dose are close together, so digoxin toxicity can happen even at ordinary doses. Call your prescriber if you notice nausea, vomiting, loss of appetite, diarrhea, confusion, dizziness, weakness, visual changes (blurred vision, or seeing yellow or green tints or halos around lights), or a heartbeat that is slow, fast, or irregular. Low potassium, low magnesium, and high calcium all increase the risk, which is why your doctor checks your potassium and kidney function and sometimes a serum digoxin level (in heart failure the usual target is roughly 0.5 to 0.9 ng/mL).

Digoxin should not be used by people with ventricular fibrillation or a hypersensitivity to digoxin or digitalis. It can cause severe slowing of the heart or advanced heart block in people with sinus node disease or existing AV block, and it can be dangerous in atrial fibrillation with an accessory pathway (Wolff-Parkinson-White). It is not recommended in acute heart attack or myocarditis, and it raises the risk of ventricular arrhythmias during electrical cardioversion. Many drugs interact with it, including amiodarone, verapamil, quinidine, clarithromycin, erythromycin, itraconazole, cyclosporine, propafenone, spironolactone, and potassium-lowering diuretics, so keep your full medication and supplement list current with your pharmacist. Do not stop digoxin abruptly without talking to your prescriber. This page is general information, not medical advice.
