Drug Class: Third-Generation Cardioselective Beta-Blocker | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Nebix 5mg Tablet? Nebix 5mg by Highnoon Laboratories contains Nebivolol Hydrochloride 5mg — the standard maintenance dose for hypertension management and a key titration milestone in chronic heart failure treatment. For hypertension, 5mg once daily provides effective and sustained blood pressure control through the combination of selective beta-1 blockade and nitric oxide-mediated vasodilation unique to third-generation Nebivolol. For heart failure patients, 5mg represents the target dose reached after gradual titration from 2.5mg — providing meaningful improvement in cardiac function with continued long-term use. Nebix 5mg is also the recommended starting and maintenance dose specifically for patients over 70 years with heart failure — where the superior cardioselectivity of Nebivolol offers better tolerability than older beta-blockers in elderly patients.
What is Nebix 5mg Used For?
- Hypertension — standard maintenance dose for blood pressure management (ہائی بلڈ پریشر)
- Stable mild to moderate chronic heart failure — particularly in patients over 70 years (دل کی کمزوری — خاص طور پر بزرگ مریضوں میں)
- Hypertension with tachycardia — combined blood pressure and heart rate control
- Cardiovascular risk reduction — long-term cardiac protection in hypertensive patients (دل کی بیماری کے خطرے کی روک تھام)
- Step-up from 2.5mg — progression to maintenance dose in heart failure titration
- Hypertension with mild kidney impairment — Nebivolol well tolerated in mild to moderate renal disease
How Does it Work? Nebivolol selectively blocks beta-1 adrenergic receptors in the heart at 5mg — reducing heart rate, decreasing the force of cardiac contraction, and lowering cardiac output to produce sustained blood pressure reduction. Simultaneously it stimulates endothelial nitric oxide synthesis — causing additional peripheral vasodilation that further reduces vascular resistance. This dual mechanism produces smoother more complete blood pressure control than beta-blockade alone. In heart failure, consistent long-term beta-1 blockade at 5mg reverses the harmful cardiac remodelling caused by chronic sympathetic overstimulation — gradually improving left ventricular function, reducing hospitalisation risk, and improving long-term survival when used as part of a comprehensive heart failure treatment programme.
Dosage and Administration
⚠️ Never stop suddenly — abrupt discontinuation causes dangerous rebound hypertension and can trigger heart attack or acute heart failure decompensation. Always increase and decrease dose gradually under cardiologist supervision. Monitor heart rate and blood pressure regularly. Takes 1 to 2 weeks for full antihypertensive effect at each dose level.

Who Should NOT Take Nebix 5mg?
- Allergy to Nebivolol, any beta-blocker, or any component of the tablet
- Severe bradycardia — resting heart rate below 60 beats per minute
- Cardiogenic shock or acutely decompensated heart failure requiring intravenous inotropic support
- Second or third degree heart block without a functioning pacemaker
- Severe asthma or chronic obstructive pulmonary disease
- Severe peripheral artery disease
- Severe liver impairment — Nebivolol extensively metabolised by liver
- Phaeochromocytoma without prior alpha-blocker cover
- Metabolic acidosis
- Pregnancy and breastfeeding — consult cardiologist before use
Side Effects
Common: Fatigue and tiredness (تھکاوٹ), slow heart rate (دل کی دھڑکن کا سست ہونا), dizziness especially on standing, cold hands and feet, mild headache, mild nausea, mild sleep disturbances — generally well tolerated and most effects reduce as body adjusts over first few weeks.
Serious — Stop and seek emergency help immediately: Severely slow heart rate below 50 beats per minute with dizziness or fainting (دل کی دھڑکن بہت سست — فوری ہسپتال جائیں), acute worsening of heart failure — sudden breathlessness, rapid unexplained weight gain with severe ankle swelling (فوری مدد لیں), significant worsening of asthma or breathing difficulty after starting tablet, severe allergic reaction with swelling of face or throat (فوری ہسپتال جائیں), severely low blood pressure with fainting (بے ہوشی — فوری مدد لیں), significant worsening of peripheral circulation — severely cold or painful limbs with skin colour changes.
Drug Interactions
| Medicine | Interaction |
|---|---|
| Verapamil / Diltiazem | Dangerous combination — severely slows heart rate and cardiac conduction — never combine without strict specialist supervision |
| Antiarrhythmics (Amiodarone, Digoxin) | Increased risk of heart block and dangerously slow heart rate — monitor closely |
| Other antihypertensives / calcium channel blockers | Additive blood pressure lowering — increased hypotension risk |
| MAO inhibitors | Increased hypertensive and cardiac risk — avoid combination |
| Antidiabetic medicines (Insulin, oral hypoglycaemics) | Nebivolol masks hypoglycaemia warning signs — monitor blood sugar more frequently |
| NSAIDs (Ibuprofen, Diclofenac) | Reduce antihypertensive effectiveness of Nebivolol — avoid regular combined use |
| Clonidine | Never stop Clonidine abruptly while on Nebivolol — severe rebound hypertension risk |
| Rifampicin | Significantly reduces Nebivolol blood levels — reduced antihypertensive effectiveness |
| Fluoxetine / Paroxetine | Increase Nebivolol blood levels — increased side effect risk including excessive bradycardia |
| Anaesthetic agents | Increased cardiovascular depression risk during surgery — inform anaesthetist before any procedure |
Storage: Store below 25°C in a cool, dry place. Protect from moisture and direct sunlight. Keep out of reach of children (بچوں کی پہنچ سے دور رکھیں). Do not use after expiry date.
FAQs
Q: Why is Nebix 5mg specifically recommended as the heart failure dose for patients over 70 years? Nebivolol's exceptional beta-1 selectivity and nitric oxide vasodilation make it significantly better tolerated in elderly heart failure patients than older less selective beta-blockers — providing meaningful cardiac benefit with less risk of bronchospasm, peripheral circulation worsening, and metabolic side effects commonly seen with older beta-blockers in this age group.
Q: How long does Nebix 5mg take to produce its full blood pressure lowering effect? Initial blood pressure reduction begins within the first few days but full and stable antihypertensive effect at 5mg typically develops over 1 to 2 weeks of consistent daily use — regular blood pressure monitoring during this period helps your cardiologist assess whether the 5mg dose is sufficient or further adjustment is needed.
Q: Can I take Nebix 5mg with my diabetes medicines safely? Yes — but with important caution. Nebivolol masks the early warning signs of low blood sugar such as rapid heartbeat and tremor, making hypoglycaemia harder to recognise. Monitor blood glucose more frequently than usual when starting or adjusting Nebix and inform your diabetes doctor about the combination.
