Medicine Description lanoxin 0.25mg
Lanoxin tablets is a medication that contains digoxin, which primarily influences the heart's contractility and rhythm. It achieves this by inhibiting the sodium-potassium ATPase enzyme, leading to an increase in intracellular sodium levels. This, in turn, causes an increase in intracellular calcium through the sodium-calcium exchanger, resulting in enhanced cardiac contractility (positive inotropic effect). Furthermore, digoxin exerts parasympathomimetic effects that slow down conduction through the atrioventricular (AV) node, thereby helping to regulate heart rate in conditions such as atrial fibrillation. The combined effects ensure improved cardiac output and stabilization of heart rhythm.
Indications and Uses of Lanoxin tablets
- Chronic heart failure
- Atrial fibrillation
- Atrial flutter
- Heart rhythm disorders (such as supraventricular tachycardia)
- Symptomatic relief of heart failure-related symptoms
Side Effects of Lanoxin tablets
- Nausea
- Vomiting
- Diarrhea
- Fatigue
- Visual disturbances (such as yellow vision)
- Confusion

- Headache
Storage and Handling
Store Lanoxin tablets at room temperature, away from excessive heat, moisture, and light. Ensure that the medication is kept in its original packaging and out of reach of children.
Patient Advice and Precautions
It's crucial to monitor for signs of digoxin toxicity, such as nausea, vomiting, or visual changes. Regular blood tests to check digoxin levels may be necessary, especially in patients with renal impairment or those taking interacting medications. Always inform your healthcare provider about all medications you are taking and any history of heart problems or electrolyte imbalances.
