Nebivolol (Nebivolol )

Nebivolol: Patient Information for Australia

Basic Product Information

Mechanism of Action

• For Patients: Nebivolol is a type of medicine called a beta-blocker. It helps to slow your heart rate, reduce blood pressure, and relieve strain on your heart. It also helps relax the blood vessels, making it easier for blood to flow.
• For Healthcare Professionals: Nebivolol is a highly selective beta₁-adrenergic receptor antagonist. It also promotes nitric oxide-mediated vasodilation, distinguishing it from other beta-blockers and contributing to its antihypertensive effect.

Pharmacokinetics

• Absorption: Nebivolol is rapidly and well absorbed after oral administration, with peak plasma concentrations within 1.5–4 hours.
• Metabolism: Extensively metabolised in the liver (mainly by CYP2D6).
• Elimination: Excreted via urine (38%) and faeces (48%), mainly as metabolites.
• Duration of Action: Long-acting; half-life ranges from 10 hours (fast metabolisers) up to 30 hours (slow metabolisers).

Use in Everyday Life and Best Practices

Nebivolol is typically used to manage high blood pressure (hypertension), and in some cases, may be used for certain types of chronic heart failure. Tablets are taken once daily, making it relatively convenient for most lifestyles. For English patients, best practice is to take the tablet at the same time each day to maintain a stable level in your bloodstream.
The usual starting dose for adults is 5 mg once daily, adjusted by your doctor as needed. In some cases, a lower starting dose may be used, especially for elderly patients or those with kidney or liver problems.
Do not stop or adjust your Nebivolol dose without consulting your prescriber.

Dosing in the Morning vs Evening

• Morning Dosing: May help with remembering to take your medication, and some patients prefer morning dosing as it fits their routine. Can help avoid insomnia in those sensitive to beta-blockers.
• Evening Dosing: Suitable for patients who experience mild dizziness after dosing or have morning routines that make evening dosing more practical.
• Clinical Tip: Take at the same time each day. If you do forget a dose, take it as soon as you remember, unless it is nearly time for your next dose.

Taking with Food or on an Empty Stomach

Nebivolol can be taken with or without food. Food does not significantly affect the absorption or effectiveness of this medication, so you may take it according to what best suits your dietary habits.
For English diets, which often include breakfast cereals, toast, or tea/coffee in the morning and cooked meals in the evening, simply choose the time that is easiest to remember.

Safety Profile and Side Effects

• Common Side Effects:
  • Headache
  • Dizziness or light-headedness (especially when standing up quickly)
  • Tiredness or fatigue
  • Slow heart rate (bradycardia)
  • Gastrointestinal symptoms (nausea, diarrhoea, constipation)
• Rare/Serious Side Effects:
  • Severe bradycardia (dangerously slow heart rhythm)
  • Worsening heart failure
  • Hypotension (low blood pressure)
  • Allergic reactions (rash, itching, swelling, breathing difficulty)
  • Liver enzyme elevations
• Warnings: People with asthma, severe heart failure, liver disease, or certain conduction defects should generally avoid Nebivolol unless prescribed by a specialist.

Guidelines for Proper Use

• Always follow the instructions provided by your doctor or pharmacist exactly.
• Do not abruptly stop taking Nebivolol, as stopping suddenly can cause problems (such as sudden increases in blood pressure or worsening heart symptoms).
• If you miss a dose, take it as soon as possible, but never double up to “catch up”.
• Store tablets in the original packaging, away from moisture and heat, and out of sight and reach of children.
• If you are due for surgery or dental work, tell your treating team you are taking Nebivolol.
• Speak to your pharmacist about medicine reviews to optimise therapy and reduce the risk of interactions, especially if managing other long-term conditions such as diabetes or asthma.

Alternative Treatment Options

  • Atenolol
  • Bisoprolol
  • Metoprolol tartrate or succinate
  • Carvedilol
• Other Antihypertensive Classes (PBS-reimbursed):
  • ACE Inhibitors (e.g., Ramipril, Perindopril)
  • Angiotensin Receptor Blockers (e.g., Irbesartan, Valsartan)
  • Calcium Channel Blockers (e.g., Amlodipine, Felodipine)
  • Diuretics (e.g., Hydrochlorothiazide, Chlorthalidone)
• Comparative Pros & Cons:

  Medicine/Class	Pros	Cons
  Nebivolol	Fewer metabolic effects, better tolerated in some patients, beneficial for heart failure	Not for those with severe asthma or slow heart rhythm
  Bisoprolol/Metoprolol	More prescriber experience, available in more strengths	May worsen glucose/lipid metabolism more than Nebivolol
  ACE Inhibitor	Good overall cardiovascular protection, kidney benefit in diabetes	May cause cough, not suitable in pregnancy

Legal, Registration, and Reimbursement Status in Australia

• Registered by the Therapeutic Goods Administration (TGA)
• Prescription Only, Schedule 4
• PBS (Pharmaceutical Benefits Scheme) listing: available for hypertension and heart failure if prescribed according to PBS criteria
• Patients may receive subsidised treatment through Medicare/PBS with a valid prescription

Latest Research and Clinical Guidance (2022–2025)

• Recent Australian and international studies confirm Nebivolol’s role in first- and second-line management of hypertension, particularly for patients at risk of metabolic side effects (see: Australian Prescriber, 2023; Therapeutics Guidelines Australia, 2024).
• Evidence reviews (BMJ, 2024) note Nebivolol’s favourable profile for blood pressure lowering and heart failure, with added benefits regarding vascular function due to nitric oxide effects.
• Nebivolol is not generally recommended as a first-line agent in younger adults or for those with isolated systolic hypertension, where ACE inhibitors or ARBs are still preferred.

FAQ: Most Common Patient Questions

1. Can I drink alcohol while taking Nebivolol?
   Moderate alcohol consumption is generally safe, but large amounts can increase your risk of dizziness or fainting. Discuss your drinking habits with your doctor or pharmacist.
2. How long should I stay on Nebivolol?
   Your doctor will determine how long you need to be on Nebivolol. For high blood pressure or heart failure, it is usually a long-term treatment. Never stop suddenly without advice.
3. Will I notice my blood pressure go down?
   Most people do not feel any different, but regular blood pressure checks will confirm the medication's effect. Always attend scheduled check-ups.
4. Is Nebivolol suitable if I have asthma?
   In general, beta-blockers can worsen asthma symptoms. Nebivolol may be less likely to do so, but it is not usually recommended for people with a history of asthma unless specifically advised by a specialist.
5. What should I do if I feel dizzy after taking Nebivolol?
   Dizziness can occur, especially when standing up quickly. Get up slowly and sit or lie down until symptoms pass. If the problem continues, consult your physician or pharmacist for advice.
