Carlov 3.125mg Tab
Carlov 3.125mg contains Carvedilol 3.125mg — the standard initiation dose for heart failure (HFrEF) therapy and the starting dose for hypertension. This non-selective beta-blocker with alpha-1 blocking activity produces vasodilation without reflex tachycardia. Take with food at initiation to reduce orthostatic hypotension risk. Prescription required.

Description
What is Carlov 3.125mg?
Carlov 3.125mg is a prescription cardiovascular tablet containing Carvedilol 3.125mg — a third-generation, non-selective beta-blocker with additional alpha-1 adrenergic blocking activity. This is the standard initiation dose for systolic heart failure (HFrEF) therapy, as well as a low starting dose for hypertension and post-MI left ventricular dysfunction. The combined beta and alpha-1 blockade produces vasodilation without reflex tachycardia. Consult your doctor; prescription required.
How Does Carlov 3.125mg Work?
Carvedilol blocks beta-1 and beta-2 adrenergic receptors plus alpha-1 receptors. Blocking beta receptors reduces heart rate and myocardial contractility; alpha-1 blockade dilates peripheral blood vessels. Together these mechanisms lower both heart rate and blood pressure while reducing cardiac afterload — the defining advantage over pure beta-blockers in heart failure management.
Uses of Carlov 3.125mg
Carlov 3.125mg is indicated as: the initiation dose for heart failure with reduced ejection fraction (HFrEF) — carvedilol has proven mortality benefit in the COPERNICUS and CAPRICORN clinical trials; starting therapy for post-MI left ventricular dysfunction; and initial treatment for hypertension in patients who may be sensitive to beta-blockers. The 3.125mg dose is designed for careful up-titration.
Dosage & Administration
Always take Carlov 3.125mg with food — food slows absorption and reduces the risk of orthostatic hypotension, which is highest at initiation. The standard heart failure protocol starts at 3.125mg twice daily for two weeks, then titrates to 6.25mg twice daily, then 12.5mg, and ultimately 25mg twice daily (target dose) as tolerated. Do not increase the dose faster than every two weeks and only when the patient is stable. Never stop abruptly — taper under medical supervision. Prescription required.
Side Effects
Common: dizziness (especially on standing), fatigue, bradycardia, hypotension, headache. Less common: oedema, dyspnoea, nausea, cold extremities. Rare but important: severe bronchospasm (contraindicated in asthma/severe COPD), masked hypoglycaemia in diabetics, worsening of Raynaud's phenomenon. The risk of orthostatic hypotension is highest with the first dose — always take with food.
Precautions
Contraindicated in decompensated heart failure requiring IV inotropic support, cardiogenic shock, second/third-degree AV block, severe bradycardia, and severe bronchospasm. Heart failure must be clinically stable (euvolaemic) before initiating carvedilol — starting during an acute decompensation is dangerous. Titrate slowly (every two weeks minimum). Caution in diabetics — may mask hypoglycaemia signs. Never stop suddenly. Prescription required.
Frequently Asked Questions
Q: Why is 3.125mg the starting dose for heart failure?
A: Heart failure patients have a fragile cardiovascular system. Starting at the lowest dose and titrating slowly every two weeks minimises the risk of worsening heart failure or dangerous hypotension during initiation.
Q: Why must Carlov 3.125mg be taken with food?
A: Food slows carvedilol's absorption rate, reducing peak blood levels and thereby significantly lowering the risk of orthostatic hypotension — the main risk when first starting the drug.
Q: How long does it take before Carlov 3.125mg shows benefit in heart failure?
A: Symptomatic benefit may take weeks to months. Mortality benefit from carvedilol in HFrEF trials was observed over 6–12 months of treatment.
