Lanoxin (Digoxin) Dosage (Kitni leni hai)
CRITICAL: Lanoxin (Digoxin) is a narrow therapeutic index (NTI) medicine. The correct dosage is determined by a qualified doctor — never change the dose on your own. The difference between therapeutic and toxic levels is very small.
Adult Dose (Baalgon ke liye)
- Maintenance dose: 0.125mg–0.25mg once daily — as prescribed
- Loading dose: (if given) — usually done in hospital or clinical setting under ECG monitoring
- Dose is based on renal function, age, body weight, and serum digoxin level
- Serum digoxin target: 0.5–2.0 ng/mL (generally 0.5–0.9 ng/mL preferred in heart failure)
- Do not exceed the recommended limit — toxicity is life-threatening
- If you miss a dose, take it as soon as you remember. If the next dose is close, skip the missed dose. Never take a double dose.
Starting Dose: As determined by doctor — may start low (0.0625mg or 0.125mg) and monitor
Usual Maintenance Dose: 0.125mg–0.25mg once daily — based on individual patient factors
Max Daily Dose: As determined by doctor, guided by serum digoxin levels and clinical response
Elderly Patients (Buzurg Mard aur Khawatin)
- In elderly patients, the dose is often kept lower (e.g. 0.0625mg or 0.125mg daily)
- Renal clearance is reduced — risk of accumulation is higher
- Closer monitoring is required
Renal Impairment (Gurde Ke Marz Mein)
- Dose reduction is required — degree of reduction depends on GFR/creatinine
- More frequent serum digoxin level monitoring needed
- Get dose advice from a specialist (nephrologist/cardiologist)
Child Dose (Bachon ke liye)
Paediatric Digoxin dose is weight-based and is set by a paediatric cardiologist. Do not calculate the dose for children yourself — the toxic dose in children is much lower than in adults.
How to Take (Kaise leni hai)
- Once daily
- Always at the same time
- Morning preferred
- With or without food — do not take with antacids
Best Time to Take (Kab leni chahiye)
- Morning — maintain a consistent time
- Daily at the same time — routine is very important for heart medicines
With Food or Empty Stomach (Khali pait ya khane ke baad)
It can be taken either way. However, absorption is significantly reduced when taken with antacids, cholestyramine, or kaolin-pectin — do not take with these; maintain a 2-hour gap.
Missed Dose (Dose chhoot jaye to kya karein)
If you miss a dose, take it as soon as you remember. If the next dose is close, skip the missed dose. Never take a double dose — a double dose of Digoxin is dangerous.
Overdose (Zyada Dose — Medical Emergency)
Digoxin overdose is a medical emergency.
Signs: severe bradycardia, arrhythmias, xanthopsia (yellow/green visual halos), nausea, vomiting, confusion.
Action: Go to the hospital emergency department immediately. Digoxin-specific antibody fragments (Digibind/DigiFab) are available as an antidote — administered in hospital.
Dose Summary Table
| Patient | Dose | Notes |
|---|---|---|
| Adult | 0.125–0.25mg once daily (typical maintenance) | Individualized — renal function + serum level guided |
| Elderly | 0.0625–0.125mg once daily (often lower) | Lower clearance — toxicity risk higher |
| Renal impairment | Dose reduced per GFR | Specialist supervision required |
| Child | Paediatric weight-based dose | Paediatric cardiologist only |
