Nebilet Plus (Hydrochlorothiazide, Nebivolol)

Nebilet Plus is used in the management of hypertension, acting on the cardiovascular system to control elevated blood pressure.

• Hypertension: reduces systolic and diastolic blood pressure and lowers risk of cardiovascular complications.
• Essential hypertension: provides consistent blood pressure control in primary hypertension.
• High blood pressure in adults: improves overall hemodynamic stability for adult patients.

• Nebivolol selectively blocks β1‑adrenergic receptors, decreasing heart rate and myocardial contractility, while also enhancing nitric‑oxide mediated vasodilation. Hydrochlorothiazide inhibits Na⁺/Cl⁻ reabsorption in the distal convoluted tubule, promoting diuresis, reducing plasma volume, and contributing to blood‑pressure lowering effects.

Nebilet Plus may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Dizziness or light‑headedness.
• Headache.
• Fatigue or mild weakness.
• Increased urination.
• Electrolyte disturbances such as low potassium.
• Elevated blood glucose levels.

Serious or Rare Side Effects

• Severe hypotension or syncope.
• Acute kidney injury or significant rise in serum creatinine.
• Allergic reactions including rash, angioedema, or anaphylaxis.
• Pancreatitis.
• Severe electrolyte imbalances (e.g., hyponatremia, hyperuricemia).

Before initiating Nebilet Plus, certain precautions should be observed to ensure safe use.

• Blood pressure monitoring: check baseline and periodic readings to avoid excessive hypotension.
• Renal function assessment: evaluate serum creatinine and eGFR, especially in patients with pre‑existing kidney disease.
• Electrolyte surveillance: monitor potassium and sodium levels during therapy.
• Diabetes caution: observe blood glucose as thiazides may raise glucose levels.
• Discontinuation: avoid abrupt cessation; taper under medical guidance to prevent rebound hypertension.
• Store at ambient temperature: keep below 25 °C in the original container, protected from moisture and direct sunlight.

Nebilet Plus can interact with several medicines, requiring careful management.

Major Interactions (Avoid)

• Concomitant use with other β‑blockers may cause excessive bradycardia.
• Strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine) can increase nebivolol plasma levels.
• Other potent diuretics may exacerbate electrolyte loss and dehydration.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) can blunt antihypertensive efficacy.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may enhance hypotensive effect.
• Calcium‑channel blockers: additive blood‑pressure lowering.
• Lithium: thiazide component can raise lithium concentrations.
• Digoxin: monitor for increased serum levels due to altered renal clearance.
