What is Lanoxin 0.25 mg?
Lanoxin is the brand name for digoxin, a prescription medicine used mainly to treat heart failure and certain abnormal heart rhythms (commonly atrial fibrillation or atrial flutter). The “0.25 mg” refers to the strength of the digoxin tablet.
What is digoxin 0.25 mg used for?
Digoxin is used when clinicians want digoxin’s effects on the heart, including:
- Heart failure (to help improve symptoms in selected patients)
- Rate control in atrial fibrillation/flutter (to slow the heart rate)
How is Lanoxin 0.25 mg taken (and why dosing is careful)?
Digoxin dosing is individualized because the drug has:
- A narrow therapeutic window (levels that are too low may not work; levels that are too high can cause toxicity)
- Risk of toxicity, which is more likely with certain drug interactions or kidney problems
Clinicians typically base the dose on factors such as age, kidney function, other medicines, and heart condition, and they may monitor blood digoxin levels.
What side effects do people ask about for Lanoxin 0.25 mg?
Common concerns with digoxin include:
- Nausea, vomiting, loss of appetite
- Dizziness
- Visual changes (classic reports include blurred vision or seeing halos)
- Heart rhythm changes if levels become too high (digoxin toxicity can affect electrical conduction)
Because toxicity can be serious, patients are usually told to contact a clinician promptly if they notice symptoms that could fit digoxin side effects.
What can interact with Lanoxin (digoxin)?
Digoxin interacts with several medicines. People commonly run into interaction risks with drugs that affect digoxin levels or heart rhythm, such as:
- Some antiarrhythmics
- Certain antibiotics
- Diuretics (especially when they cause low potassium)
- Drugs that affect liver metabolism or transporters used by digoxin
If you share your other medications, I can help you flag the types of interactions clinicians watch for.
Who should be extra cautious?
Extra caution is usually needed for people with:
- Kidney impairment (digoxin is cleared through the kidneys)
- Low potassium or low magnesium
- Older age, where toxicity risk can be higher
- Multiple comorbidities and complex medication regimens
Is Lanoxin 0.25 mg the only digoxin option?
Lanoxin is a brand; digoxin also comes in generic forms with the same active ingredient (digoxin). Switching products sometimes still needs supervision because dosing accuracy and absorption can matter.

If you tell me what you need (for example: “What is it for?”, “Dose for atrial fibrillation?”, “Side effects I should watch for?”, “Is 0.25 mg safe with kidney disease?”, or “Is it the same as generic digoxin?”), I can tailor the answer to that exact situation.
