Digoxin (commonly known by the brand name Lanoxin) is a specialized medication derived from the digitalis (foxglove) plant. It belongs to the class of drugs known as cardiac glycosides. It is specifically engineered to manage heart rhythm and strengthen the heart's pumping action. Digoxin works by inhibiting the sodium-potassium ATPase pump in heart cells, which increases the concentration of calcium inside the cells. This leads to a stronger contraction of the heart muscle and a slowing of the electrical conduction through the atrioventricular (AV) node, effectively regulating a rapid heart rate.
Product Type: Cardiac Glycoside (Inotrope/Anti-arrhythmic)
Active Ingredient: Digoxin (62.5 micrograms or 0.0625mg)
Manufacturer: Aspen (Lanoxin) / Various Generic Equivalents
Pack Size: 28, 30, or 100 Tablets
Route: Oral
Availability: Strictly Prescription Required (POM) — Cardiologist consultation mandatory
Suitable For: Adults and children (specialized pediatric dosing)
The 62.5mcg strength is often used as a maintenance dose, particularly for elderly patients or those with reduced kidney function:
Atrial Fibrillation (AFib): Controlling a rapid or irregular heart rate originating in the upper chambers of the heart.
Chronic Heart Failure: Improving the heart's ability to pump blood and reducing hospitalizations in patients with reduced ejection fraction.
Atrial Flutter: Managing rapid, organized electrical signals in the heart's atria.
Pediatric Heart Conditions: Specialized dosing for children with congenital heart issues.
Digoxin Toxicity: Because Digoxin has a "narrow therapeutic index," the difference between a helpful dose and a toxic dose is very small. Symptoms of toxicity include nausea, vomiting, loss of appetite, and "Yellow-Green" blurred vision or seeing halos around lights. Kidney Function: Digoxin is cleared by the kidneys. If your kidney function declines, the drug can build up to dangerous levels. Regular blood tests (U&E) are required. Electrolyte Balance: Low Potassium or low Magnesium levels in your blood significantly increase the risk of Digoxin toxicity. Heart Block: Do not use if you have certain types of heart block (e.g., 2nd or 3rd degree) unless you have a permanent pacemaker. Pulse Check: Many doctors recommend checking your pulse before taking your dose. If it is lower than 60 beats per minute, consult your doctor before taking the tablet.
For maximum safety, Digoxin must be taken exactly as prescribed, usually at the same time each day.
Standard Dosage:
Adults: Typically one 62.5mcg or 125mcg tablet once daily.
Loading Dose: In some cases, a doctor may start with a higher "loading dose" over 24 hours to reach effective levels quickly.
Application Tips:
Consistency: Take the tablet with a full glass of water, with or without food, but be consistent with your choice.
Avoid High Fiber: Taking Digoxin with a very high-fiber meal (like bran) can reduce its absorption.
Do Not Skip: If you miss a dose, take it as soon as you remember, unless it is within 12 hours of your next dose. Never take a double dose.
Monitoring: Your doctor will perform periodic blood tests to check your "Digoxin Level" to ensure it stays within the safe range ($0.5 \text{ to } 2.0 \text{ ng/mL}$).
Common side effects include mild dizziness, headache, or a slight skin rash. More serious effects involve changes in heart rhythm (too slow or skipped beats). If you experience sudden confusion, extreme weakness, or the characteristic "yellow vision," contact your doctor or Sanlive Pharmacy immediately, as these are signs of toxicity.
Store in a cool, dry place below 25°C, protected from light. Keep the tablets in their original blister packaging until the moment of use. Keep out of reach of children.
Q: Why is the dose in "micrograms" ($\mu\text{g}$)?
A: Digoxin is extremely potent. A dose of 62.5mcg is only $0.0625$ of a milligram. This precision is necessary because the drug is very powerful even in tiny amounts.
Q: Can I take it with "Antacids"?
A: Use caution. Antacids (like Gaviscon or Mist Mag) can reduce the absorption of Digoxin. Space them by at least 2 hours.
Q: What is the "Yellow Vision" I keep hearing about?
A: High levels of Digoxin can affect the retina in the eye, causing people to see a yellow or green tint or "halos" around objects. This is a classic warning sign of toxicity.
Q: Does it interact with "Antibiotics"?
A: Yes. Some antibiotics (like Erythromycin or Clarithromycin) can significantly increase Digoxin levels in the blood. Always tell your pharmacist if you are starting a new medication.
