Liver disease
Use of another medication similar to this one. If you are unsure, consult your doctor or pharmacist.
* Breast-feeding. It is recommended that you do not breast-feed while taking this medication.
This list is not exhaustive, and it is crucial to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health problems with your doctor and pharmacist. They will help determine whether it is safe to take this medication with your other medications and health conditions. Never start, stop, or change the dose of any medication without first consulting your doctor.
Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication.
To ensure your safety, avoid driving and other activities that require alertness until you understand how this medication affects you. When changing positions, such as standing up from a sitting or lying down position, do so slowly to minimize the risk of dizziness or fainting. Be cautious when navigating stairs.
Regularly monitor your blood pressure and heart rate as directed by your doctor. Additionally, have your blood work checked as instructed by your doctor, and discuss the results with them.
Please note that this medication may interfere with certain laboratory tests. Inform all your healthcare providers and laboratory personnel that you are taking this medication.
Before consuming alcohol, consult with your doctor. This medication may mask symptoms of low blood sugar, such as a rapid heartbeat, which can increase the risk of severe or prolonged hypoglycemia, particularly in individuals with diabetes, children, and those who are fasting or undergoing surgery.
If you have diabetes, it is crucial to closely monitor your blood sugar levels. Before taking any over-the-counter (OTC) products that may increase blood pressure, such as cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, or certain natural products, consult with your doctor.
Do not abruptly stop taking this medication, as this may lead to worsened chest pain or even a heart attack, especially in individuals with certain types of heart disease. To minimize the risk of side effects, your doctor will instruct you on how to gradually discontinue the medication. If you experience new or worsening chest pain or other heart problems, contact your doctor immediately.
If you have a history of severe allergic reactions, discuss this with your doctor, as you may be at risk of an even more severe reaction if you are exposed to the allergen again. If you use epinephrine to treat severe allergic reactions, inform your doctor, as this medication may reduce the effectiveness of epinephrine.
This medication may also make it more challenging to recognize symptoms of an overactive thyroid, such as a rapid heartbeat. If you have an overactive thyroid and stop taking this medication suddenly, your condition may worsen and become life-threatening. Consult with your doctor before making any changes to your medication regimen.
If you are pregnant or plan to become pregnant, discuss the benefits and risks of taking this medication with your doctor.
Overdose Information
Overdose Symptoms:
- Severe bradycardia (very slow heart rate)
- Hypotension (very low blood pressure)
- Acute cardiac insufficiency (heart failure)
- Cardiogenic shock
- Bronchospasm
- Vomiting
- Impaired consciousness
- Generalized seizures
What to Do:
Seek immediate medical attention or call 911. For poison control, call 1-800-222-1222. Treatment is supportive and symptomatic, including atropine for bradycardia, vasopressors for hypotension, glucagon, and possibly cardiac pacing.
Drug Interactions
Major Interactions
- Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine, quinidine, propafenone): May significantly increase nebivolol plasma concentrations, increasing risk of bradycardia and other adverse effects. Consider lower nebivolol dose.
- Other beta-blockers: Additive effects on heart rate and blood pressure.
- Calcium channel blockers (e.g., verapamil, diltiazem): Increased risk of bradycardia, AV block, and heart failure. Monitor closely.
Moderate Interactions
- Clonidine: May potentiate rebound hypertension upon clonidine withdrawal. Discontinue nebivolol several days before clonidine withdrawal.
- Digitalis glycosides: Increased risk of bradycardia.
- NSAIDs (e.g., ibuprofen, naproxen): May reduce the antihypertensive effect of nebivolol.
- Antidiabetic agents (insulin, oral hypoglycemics): Beta-blockers may mask symptoms of hypoglycemia (e.g., tachycardia).
- Anesthetics (general): May potentiate hypotensive effects and myocardial depression.
Minor Interactions
- Alcohol: May cause additive hypotensive effects.
Monitoring
Baseline Monitoring
Rationale: To establish baseline and guide initial dosing.
Timing: Prior to initiation
Rationale: To establish baseline and assess for bradycardia.
Timing: Prior to initiation
Rationale: To assess need for dose adjustment in renal impairment.
Timing: Prior to initiation
Rationale: To assess need for dose adjustment in hepatic impairment.
Timing: Prior to initiation
Routine Monitoring
Frequency: Regularly, especially during dose titration and periodically thereafter (e.g., monthly, then every 3-6 months)
Target: <130/80 mmHg (individualized based on guidelines and patient comorbidities)
Action Threshold: Persistent elevation above target or symptomatic hypotension
Frequency: Regularly, especially during dose titration and periodically thereafter
Target: 50-90 bpm (avoid symptomatic bradycardia <50 bpm)
Action Threshold: HR <50 bpm or symptomatic bradycardia
Frequency: Periodically
Target: Absence of new or worsening symptoms (e.g., dyspnea, edema, weight gain)
Action Threshold: Development or worsening of heart failure symptoms
Symptom Monitoring
- Dizziness
- Lightheadedness
- Fatigue
- Shortness of breath
- Swelling in ankles/feet
- Bradycardia (slow heart rate)
- Cold extremities
Special Patient Groups
Pregnancy
Use during pregnancy is generally not recommended unless the potential benefit justifies the potential risk to the fetus. Based on animal data, nebivolol may cause fetal harm. Neonates exposed to beta-blockers in utero may be at risk for bradycardia, hypoglycemia, and respiratory depression.
Trimester-Specific Risks:
Lactation
It is unknown if nebivolol is excreted in human milk. Due to the potential for serious adverse reactions in breastfed infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Not recommended for use in children.
Geriatric Use
No overall differences in safety or effectiveness were observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Consider starting with a lower dose (2.5 mg) in elderly patients.
Clinical Information
Clinical Pearls
- Nebivolol is unique among beta-blockers due to its additional vasodilatory effect mediated by nitric oxide release, which may lead to a lower incidence of common beta-blocker side effects like fatigue and erectile dysfunction.
- It is highly beta-1 selective, but selectivity is dose-dependent and may decrease at higher doses.
- Patients who are poor CYP2D6 metabolizers will have significantly higher plasma concentrations of nebivolol and its active metabolites, requiring lower doses.
- Always taper nebivolol slowly over 1-2 weeks when discontinuing, especially in patients with coronary artery disease, to avoid rebound hypertension, angina, or myocardial infarction.
- Monitor heart rate closely, especially in patients with pre-existing bradycardia or those taking other medications that slow heart rate (e.g., verapamil, diltiazem, digoxin).
Alternative Therapies
- Other beta-blockers (e.g., metoprolol, carvedilol, atenolol)
- ACE inhibitors (e.g., lisinopril, enalapril)
- Angiotensin Receptor Blockers (ARBs) (e.g., valsartan, losartan)
- Calcium Channel Blockers (e.g., amlodipine, nifedipine)
- Thiazide diuretics (e.g., hydrochlorothiazide, chlorthalidone)
