If you are pregnant, planning to become pregnant, or breastfeeding, discuss the benefits and risks of this medication with your doctor to ensure the best possible outcome for you and your baby.
Mouth (Local Anesthesia)
Do not eat or drink until the numbness in your mouth has resolved, as you may accidentally bite your tongue.
Spinal (Regional Anesthesia)
This medication may cause temporary loss of sensation and motor function in the lower half of your body. Until these effects have worn off and you have regained normal feeling and movement, do not attempt to get out of bed or engage in any activities that require physical mobility.
Overdose Information
Overdose Symptoms:
- Severe CNS toxicity (e.g., seizures, unconsciousness, respiratory arrest)
- Severe cardiovascular toxicity (e.g., profound hypotension, bradycardia, ventricular arrhythmias, asystole, cardiac arrest)
What to Do:
Seek immediate emergency medical attention. Call 911 or your local emergency number. In the US, you can also call Poison Control at 1-800-222-1222. Management involves maintaining airway, breathing, and circulation, administering oxygen, managing seizures (e.g., with benzodiazepines), and treating cardiovascular collapse (e.g., with vasopressors, atropine, lipid emulsion therapy).
Drug Interactions
Contraindicated Interactions
- Intravenous regional anesthesia (IVRA) with bupivacaine (due to high risk of cardiac arrest)
- Known hypersensitivity to amide-type local anesthetics or epinephrine
Major Interactions
- Monoamine Oxidase Inhibitors (MAOIs): Potentiate pressor effects of epinephrine, leading to hypertensive crisis.
- Tricyclic Antidepressants (TCAs): Potentiate pressor effects of epinephrine, leading to severe hypertension and arrhythmias.
- Non-selective Beta-blockers: May cause severe hypertension followed by bradycardia due to unopposed alpha-adrenergic effects of epinephrine.
- General Anesthetics (e.g., Halogenated hydrocarbons like Halothane, Enflurane, Isoflurane): May sensitize the myocardium to epinephrine, increasing risk of arrhythmias.
- Other Local Anesthetics: Additive systemic toxicity.
- Antiarrhythmics (e.g., Class I antiarrhythmics like Lidocaine, Mexiletine): Additive cardiac effects, increased risk of toxicity.
Moderate Interactions
- Phenothiazines and Butyrophenones: May reverse the pressor effect of epinephrine, leading to hypotension.
- Oxytocic Drugs (e.g., Ergot alkaloids): May cause severe persistent hypertension or cerebrovascular accidents when given with vasoconstrictors like epinephrine.
- Alpha-adrenergic blocking agents: May diminish the pressor response to epinephrine.
- Diuretics: May reduce arterial responsiveness to pressor agents like epinephrine.
Minor Interactions
- Cimetidine: May inhibit bupivacaine metabolism, potentially increasing plasma levels (clinical significance usually minor).
Monitoring
Baseline Monitoring
Rationale: To identify contraindications, allergies, pre-existing conditions (cardiac, hepatic, renal disease, neurological disorders) that may affect drug metabolism or increase risk of adverse events.
Timing: Prior to administration
Rationale: To establish baseline and detect early signs of systemic toxicity or adverse reactions to epinephrine.
Timing: Prior to administration
Rationale: To prevent hypersensitivity reactions.
Timing: Prior to administration
Routine Monitoring
Frequency: Every 5-15 minutes during and immediately after administration, then as clinically indicated.
Target: Within patient's normal range, or as per clinical protocol.
Action Threshold: Significant deviations (e.g., hypotension, bradycardia, tachycardia, hypertension, respiratory depression) warrant immediate intervention.
Frequency: Continuously during and immediately after administration.
Target: Alert and oriented, no signs of CNS toxicity.
Action Threshold: Signs of CNS toxicity (e.g., dizziness, tinnitus, perioral numbness, metallic taste, confusion, tremors, seizures) require immediate cessation of administration and supportive care.
Frequency: Continuous during administration and recovery.
Target: Normal sinus rhythm, no significant arrhythmias.
Action Threshold: Arrhythmias (e.g., ventricular tachycardia, fibrillation, severe bradycardia) require immediate intervention.
Frequency: As needed to assess efficacy and determine need for additional analgesia.
Target: Acceptable pain level for the procedure.
Action Threshold: Inadequate pain control may indicate need for re-dosing or alternative analgesia.

Special Patient Groups
Pregnancy
Category C. Use only if the potential benefit justifies the potential risk to the fetus. Bupivacaine crosses the placenta. Epinephrine can affect uterine blood flow and contractility.
Trimester-Specific Risks:
Lactation
L2 (Bupivacaine). Bupivacaine is excreted into breast milk in small amounts. Epinephrine is rapidly metabolized and unlikely to be present in significant amounts. Generally considered compatible with breastfeeding when used as a local anesthetic, but observe infant for drowsiness or feeding difficulties.
Pediatric Use
Use with extreme caution, especially in infants and young children, due to increased susceptibility to systemic toxicity and immature metabolic pathways. Dosing must be carefully calculated on a mg/kg basis, and the lowest effective dose should be used. Accidental intravascular injection is a higher risk in this population.
Geriatric Use
Use with caution. Elderly patients may be more susceptible to systemic toxicity due to decreased hepatic and renal function, reduced protein binding, and altered body composition. Start with lower doses and titrate slowly. Monitor closely for adverse effects, especially CNS and cardiovascular toxicity.
Clinical Information
Clinical Pearls
- Always aspirate prior to injection to avoid accidental intravascular administration, which can lead to severe systemic toxicity, including cardiac arrest.
- The presence of epinephrine prolongs the duration of action and reduces systemic absorption of bupivacaine, but also adds the risk of epinephrine-related side effects (e.g., tachycardia, hypertension, anxiety).
- Bupivacaine has a higher potential for cardiotoxicity compared to lidocaine, especially with accidental intravascular injection. Resuscitation can be difficult.
- Lipid emulsion therapy (Intralipid) is the antidote for severe local anesthetic systemic toxicity (LAST) and should be readily available when administering bupivacaine.
- Do not use bupivacaine with epinephrine for areas with end-arterial supply (e.g., fingers, toes, nose, penis, earlobe) due to the risk of ischemia and necrosis from vasoconstriction.
Alternative Therapies
- Lidocaine (without epinephrine)
- Ropivacaine
- Levobupivacaine
- Chloroprocaine
- General anesthesia
- Regional anesthesia (e.g., spinal anesthesia)
- Non-opioid analgesics (e.g., NSAIDs, acetaminophen)
- Opioid analgesics
