🚨 Boxed Warning ▾
WARNING: RISK OF CARDIAC ARREST WITH USE OF BUPIVACAINE HYDROCHLORIDE IN OBSTETRICAL ANESTHESIA There have been reports of cardiac arrest with difficult resuscitation or death during use of bupivacaine hydrochloride for epidural anesthesia in obstetrical patients. In most cases, this has followed use of the 0.75% (7.5 mg/mL) concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management.
Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% (7.5 mg/mL) concentration of bupivacaine hydrochloride is not recommended for obstetrical anesthesia and should be reserved for surgical procedures where a high degree of muscle relaxation and prolonged effect are necessary [see Warnings and Precautions (5.1) ]. WARNING: RISK OF CARDIAC ARREST WITH USE OF BUPIVACAINE HYDROCHLORIDE IN OBSTETRICAL ANESTHESIA See full prescribing information for complete boxed warning.

⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Not for intrathecal use. ( 2.1 ) Avoid use of solutions containing antimicrobial preservatives (i.e., multiple-dose vials) for epidural or caudal anesthesia. ( 2.1 , 5.4 ) See full prescribing information for: - Recommended concentrations and dosages of bupivacaine hydrochloride injection according to type of block.
( 2.2 ) - Additional dosage and administration information pertaining to use in epidural anesthesia and use in ophthalmic surgery. ( 2.3 , 2.6 )
2.1Important Dosage and Administration Information Bupivacaine hydrochloride injection is not for intrathecal use. Avoid use of bupivacaine hydrochloride injection solutions containing antimicrobial preservatives (i.e., multiple-dose vials) for epidural or caudal anesthesia [see Warnings and Precautions (5.4) ] . Discard unused portions of solution not containing preservatives, i.e., those supplied in single-dose vials, following initial use.
Visually inspect this product for particulate matter and discoloration prior to administration whenever solution and container permit. Bupivacaine hydrochloride injection is clear, colorless solution. Do not administer solutions which are discolored or contain particulate matter.
Mixing or the prior or intercurrent use of any other local anesthetic with bupivacaine hydrochloride injection is not recommended because of insufficient data on the clinical use of such mixtures. Administration Precautions Bupivacaine hydrochloride injection is to be administered in carefully adjusted dosages by or under the supervision of experienced clinicians who are well versed in the diagnosis and management of dose-related toxicity and other acute emergencies which might arise from the block to be employed. Use bupivacaine hydrochloride injection only if the following are immediately available: oxygen, cardiopulmonary resuscitative equipment and drugs, and the personnel resources needed for proper management of toxic reactions and related emergencies [see Warnings and Precautions (5.2) , Adverse Reactions (6) , Overdosage (10) ].
The toxic effects of local anesthetics are additive. Monitor for neurologic and cardiovascular effects related to local anesthetic systemic toxicity when additional local anesthetics are administered with bupivacaine hydrochloride injection [see Warnings and Precautions (5.2) , Drug Interactions (7.1) , Overdosage (10) ]. Aspirate for blood or cerebrospinal fluid (where applicable) prior to injecting bupivacaine hydrochloride injection, both the initial dose and all subsequent doses, to avoid intravascular or intrathecal injection.
However, a negative aspiration for blood or cerebrospinal fluid does not ensure against an intravascular or intrathecal injection [see Warnings and Precautions (5.9) ] . Avoid rapid injection of a large volume of bupivacaine hydrochloride injection and use fractional (incremental) doses when feasible. During major regional nerve blocks, such as those of the brachial plexus or lower extremity, the patient should have an indwelling intravenous catheter to assure adequate intravenous access.
The lowest dosage of bupivacaine hydrochloride injection that results in effective anesthesia should be used to avoid high plasma levels and serious adverse reactions. Perform careful and constant monitoring of cardiovascular and respiratory (adequacy of oxygenation and ventilation) vital signs and the patient’s level of consciousness after each local anesthetic injection.
2.2Recommended Concentrations and Dosages of Bupivacaine Hydrochloride Injection The dosage of bupivacaine hydrochloride injection administered varies with the anesthetic procedure, the area to be anesthetized, the vascularity of the tissues, the number of neuronal segments to be blocked, the depth of anesthesia and degree of muscle relaxation required, the duration of anesthesia desired, individual tolerance, and the physical condition of the patient. Administer the smallest dosage and concentration required to prod…

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Dose-Related Toxicity : Monitor cardiovascular and respiratory vital signs and patient’s state of consciousness after injection of bupivacaine hydrochloride. ( 5.2 ) Methemoglobinemia : Cases of methemoglobinemia have been reported in association with local anesthetic use. See full prescribing information for more detail on managing these risks.
( 5.3 ) Chondrolysis with Intra-Articular Infusion : Intra-articular infusions of local anesthetics including bupivacaine hydrochloride following arthroscopic and other surgical procedures is an unapproved use, and there have been post-marketing reports of chondrolysis in patients receiving such infusions. ( 5.5 ) Risk of Cardiac Arrest with Intravenous Regional Anesthesia Use (Bier Block) : There have been reports of cardiac arrest and death during the use of bupivacaine for intravenous regional anesthesia (Bier Block).
( 5.7 ) Risk of Systemic Toxicities with Unintended Intravascular or Intrathecal Injection : Unintended intravascular or intrathecal injection may be associated with systemic toxicities, including CNS or cardiorespiratory depression and coma, progressing ultimately to respiratory arrest. Aspirate for blood or cerebrospinal fluid (where applicable) prior to each dose. ( 5.9 )
5.1Risk of Cardiac Arrest with Use of Bupivacaine Hydrochloride in Obstetrical Anesthesia There have been reports of cardiac arrest with difficult resuscitation or death during use of bupivacaine hydrochloride for epidural anesthesia in obstetrical patients. In most cases, this has followed use of the 0.75% (7.5 mg/mL) concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management.
Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% (7.5 mg/mL) concentration of bupivacaine hydrochloride is not recommended for obstetrical anesthesia and should be reserved for surgical procedures where a high degree of muscle relaxation and prolonged effect are necessary.
5.2Dose-Related Toxicity The safety and effectiveness of bupivacaine hydrochloride depend on proper dosage, correct technique, adequate precautions, and readiness for emergencies. Careful and constant monitoring of cardiovascular and respiratory (adequacy of ventilation) vital signs and the patient’s state of consciousness should be performed after injection of bupivacaine hydrochloride solution. Possible early warning signs of central nervous system (CNS) toxicity are restlessness, anxiety, incoherent speech, lightheadedness, numbness and tingling of the mouth and lips, metallic taste, tinnitus, dizziness, blurred vision, tremors, twitching, CNS depression, or drowsiness.
Delay in proper management of dose-related toxicity, underventilation from any cause, and/or altered sensitivity may lead to the development of acidosis, cardiac arrest, and, possibly, death. During major regional nerve blocks, such as those of the brachial plexus or lower extremity, the patient should have an indwelling intravenous catheter to assure adequate intravenous access. Use the lowest dosage of bupivacaine hydrochloride that results in effective anesthesia to avoid high plasma levels and serious adverse effects.
Avoid rapid injection of a large volume of bupivacaine hydrochloride solution and administer fractional (incremental) doses when feasible. Injection of repeated doses of bupivacaine hydrochloride may cause significant increases in plasma levels with each repeated dose due to slow accumulation of the drug or its metabolites, or to slow metabolic degradation. Tolerance to elevated blood levels varies with the status of the patient.
Debilitated, elderly patients and acutely ill patients should be given reduced doses commensurate with their age and physical status.
5.3Methemoglobinemia Cases of methemoglobinemia have been reported in association with local anesthetic use. Alth…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions have been reported and described in the Warnings and Precautions section of the labeling: Cardiac Arrest in Obstetrical Anesthesia [see Warnings and Precautions (5.1) ] Dose-Related Toxicity [see Warnings and Precautions (5.2) ] Methemoglobinemia [see Warnings and Precautions (5.3) ] Chondrolysis with Intra-Articular Infusion [see Warnings and Precautions (5.5) ] Cardiac Arrest with Intravenous Regional Anesthesia Use [see Contraindications (4) , Warnings and Precautions (5.7) ] Systemic Toxicities with Unintended Intravascular or Intrathecal Injection [see Warnings and Precautions (5.9) ] Respiratory Arrest Following Retrobulbar Block [see Warnings and Precautions (5.15) ] The following adverse reactions from voluntary reports or clinical studies have been reported with bupivacaine.
Because many of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Adverse reactions to bupivacaine hydrochloride are characteristic of those associated with other amide-type local anesthetics. A major cause of adverse reactions to this group of drugs is excessive plasma levels, which may be due to overdosage, unintentional intravascular injection, or slow metabolic degradation.
The most commonly encountered acute adverse reactions that demand immediate counter-measures were related to the CNS and the cardiovascular system. These adverse reactions were generally dose-related and due to high plasma levels which may have resulted from overdosage, rapid absorption from the injection site, diminished tolerance, or from unintentional intravascular injection of the local anesthetic solution. In addition to systemic dose-related toxicity, unintentional intrathecal injection of drug during the intended performance of caudal or lumbar epidural block or nerve blocks near the vertebral column (especially in the head and neck region) has resulted in underventilation or apnea ("Total or High Spinal").
Also, hypotension due to loss of sympathetic tone and respiratory paralysis or underventilation due to cephalad extension of the motor level of anesthesia have occurred. This has led to secondary cardiac arrest when untreated. Nervous System Disorders : Adverse reactions were characterized by excitation and/or depression of the central nervous system and included restlessness, anxiety, dizziness, tinnitus, blurred vision, tremors, convulsions, drowsiness, unconsciousness, respiratory arrest, nausea, vomiting, chills, pupillary constriction.
In the practice of caudal or lumbar epidural block, unintentional penetration of the subarachnoid space by the catheter or needle has occurred. Subsequent adverse effects may have depended partially on the amount of drug administered intrathecally and the physiological and physical effects of a dural puncture. A high spinal has been characterized by paralysis of the legs, loss of consciousness, respiratory paralysis, and bradycardia.
Neurologic effects following epidural or caudal anesthesia have included spinal block of varying magnitude (including high or total spinal block); hypotension secondary to spinal block; urinary retention; fecal and urinary incontinence; loss of perineal sensation and sexual function; persistent anesthesia, paresthesia, weakness, paralysis of the lower extremities and loss of sphincter control, all of which had slow, incomplete, or no recovery; headache; backache; septic meningitis; meningismus; slowing of labor; increased incidence of forceps delivery; and cranial nerve palsies due to traction on nerves from loss of cerebrospinal fluid.
Neurologic effects following other procedures or routes of administration have included persistent anesthesia, paresthesia, weakness, paralysis, all with slow, incomplete, or no recovery. Convulsions: Incidence varied with the procedure used and the…

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pediatric Use : Administration of bupivacaine hydrochloride in pediatric patients younger than 12 years is not recommended. ( 8.4 ) Geriatric Use : Patients 65 years and over, particularly those with hypertension, may be at increased risk for developing hypotension while undergoing anesthesia with bupivacaine hydrochloride. ( 8.5 ) Moderate to Severe Hepatic Impairment : Consider increased monitoring for bupivacaine systemic toxicity.
( 8.6 )
8.1Pregnancy Risk Summary Bupivacaine hydrochloride is contraindicated for obstetrical paracervical block anesthesia. Its use in this technique has resulted in fetal bradycardia and death [see Contraindications (4) , Warnings and Precautions (5.1) ] . There are no available data on use of bupivacaine hydrochloride in pregnant women to inform a drug-associated risk of adverse developmental outcomes.
In animal studies, embryo-fetal lethality was noted when bupivacaine was administered subcutaneously to pregnant rabbits during organogenesis at clinically relevant doses. Decreased pup survival was observed in a rat pre-and post-natal developmental study (dosing from implantation through weaning) at a dose level comparable to the daily maximum recommended human dose (MRHD) on a body surface area (BSA) basis. Based on animal data, advise pregnant women of the potential risks to a fetus (see Data) .
Local anesthetics rapidly cross the placenta, and when used for epidural, caudal, or pudendal block anesthesia, can cause varying degrees of maternal, fetal, and neonatal toxicity [see Clinical Pharmacology (12.3) ] . The incidence and degree of toxicity depend upon the procedure performed, the type, and amount of drug used, and the technique of drug administration. Adverse reactions in the parturient, fetus, and neonate involve alterations of the CNS, peripheral vascular tone, and cardiac function.
If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, inform the patient of the potential hazard to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Clinical Considerations Maternal Adverse Reactions Maternal hypotension has resulted from regional anesthesia. Local anesthetics produce vasodilation by blocking sympathetic nerves. The supine position is dangerous in pregnant women at term because of aortocaval compression by the gravid uterus.
Therefore, during treatment of systemic toxicity, maternal hypotension or fetal bradycardia following regional block, the parturient should be maintained in the left lateral decubitus position if possible, or manual displacement of the uterus off the great vessels be accomplished. Elevating the patient's legs will also help prevent decreases in blood pressure. The fetal heart rate also should be monitored continuously and electronic fetal monitoring is highly advisable.
Labor or Delivery Epidural, caudal, or pudendal anesthesia may alter the forces of parturition through changes in uterine contractility or maternal expulsive efforts. Epidural anesthesia has been reported to prolong the second stage of labor by removing the parturient's reflex urge to bear down or by interfering with motor function. The use of obstetrical anesthesia may increase the need for forceps assistance.
The use of some local anesthetic drug products during labor and delivery may be followed by diminished muscle strength and tone for the first day or two of life. This has not been reported with bupivacaine. It is extremely important to avoid aortocaval compression by the gravid uterus during administration of regional block to parturients.
To do this, the patient must be maintained in the left lateral decubitus position or a blanket roll or sandbag may be placed beneath the…

In clinical studies of bupivacaine, elderly patients reached the maximal spread of analgesia and maximal motor blockade more rapidly than younger adult patients. Differences in various pharmacokinetic parameters have been observed between elderly and younger adult patients [see Clinical Pharmacology (12.3) ] .
This product is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Elderly patients may require lower doses of bupivacaine hydrochloride.
🆘 Overdosage ▾
10 OVERDOSAGE Clinical Presentation Acute emergencies from use of bupivacaine hydrochloride are generally related to high plasma levels encountered during therapeutic use or to unintended intrathecal injection [see Warnings and Precautions (5.2 , 5.9) , Adverse Reactions (6) ]. If not treated immediately, convulsions with simultaneous hypoxia, hypercarbia, and acidosis plus myocardial depression from the direct effects of bupivacaine may result in cardiac arrhythmias, bradycardia, asystole, ventricular fibrillation, or cardiac arrest.
Respiratory abnormalities, including apnea, may occur. Hypoventilation or apnea due to unintentional intrathecal injection of bupivacaine hydrochloride may produce these same signs and also lead to cardiac arrest if ventilatory support is not instituted. If cardiac arrest should occur, successful outcome may require prolonged resuscitative efforts.
Management The first step in the management of systemic toxic reactions, as well as hypoventilation or apnea due to unintentional intrathecal injection of bupivacaine hydrochloride, consists of immediate attention to the establishment and maintenance of a patent airway and effective assisted or controlled ventilation with 100% oxygen with a delivery system capable of permitting immediate positive airway pressure by mask. Endotracheal intubation, using drugs and techniques familiar to the clinician, may be indicated after initial administration of oxygen by mask if difficulty is encountered in the maintenance of a patent airway, or if prolonged ventilatory support (assisted or controlled) is indicated.
If necessary, use drugs to manage the convulsions. A bolus intravenous dose of a benzodiazepine will counteract CNS stimulation related to bupivacaine hydrochloride. Immediately after the institution of ventilatory measures, evaluate the adequacy of the circulation.
Supportive treatment of circulatory depression may require Advance Cardiac Life Support measures.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Bupivacaine blocks the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination, and conduction velocity of affected nerve fibers. Clinically, the order of loss of nerve function is as follows: (1) pain, (2) temperature, (3) touch, (4) proprioception, and (5) skeletal muscle tone.
12.2Pharmacodynamics Systemic absorption of bupivacaine produces effects on the cardiovascular system and CNS. At blood concentrations achieved with normal therapeutic doses, changes in cardiac conduction, excitability, refractoriness, contractility, and peripheral vascular resistance are minimal. However, toxic blood concentrations depress cardiac conduction and excitability, which may lead to atrioventricular block, ventricular arrhythmias, and cardiac arrest, sometimes resulting in fatalities.
In addition, myocardial contractility is depressed and peripheral vasodilation occurs, leading to decreased cardiac output and arterial blood pressure. These cardiovascular changes are more likely to occur after unintended intravascular injection of bupivacaine [see Warnings and Precautions (5.9) ] . Following systemic absorption, bupivacaine can produce CNS stimulation, CNS depression, or both.
Apparent central stimulation is manifested as restlessness, tremors, and shivering, progressing to convulsions, followed by CNS depression and coma progressing ultimately to respiratory arrest. However, bupivacaine has a primary depressant effect on the medulla and on higher centers. The depressed stage may occur without a prior excited state.
The duration of local anesthesia after administration of bupivacaine hydrochloride is longer than that observed after administration of other commonly used short-acting local anesthetics. There appears to be period of analgesia that persists after the resolution of the block and return of sensation.
12.3Pharmacokinetics Systemic plasma levels of bupivacaine following administration of bupivacaine hydrochloride do not correlate with local efficacy. Absorption The rate of systemic absorption of bupivacaine is dependent upon the total dose and concentration of drug administered, the route of administration, the vascularity of the administration site, and the presence or absence of epinephrine in the anesthetic solution. A dilute concentration of usually reduces the rate of absorption and peak plasma concentration of bupivacaine, permitting the use of moderately larger total doses and sometimes prolonging the duration of action [see Dosage and Administration (2) ] .
After injection of bupivacaine hydrochloride for caudal, epidural, or peripheral nerve block, peak levels of bupivacaine in the blood are reached in 30 to 45 minutes, followed by a decline to insignificant levels during the next three to six hours. Distribution Bupivacaine appears to cross the placenta by passive diffusion. The rate and degree of diffusion is governed by (1) the degree of plasma protein binding, (2) the degree of ionization, and (3) the degree of lipid solubility.
Fetal/maternal ratios of bupivacaine appear to be inversely related to the degree of plasma protein binding, because only the free, unbound drug is available for placental transfer. Bupivacaine with a high protein binding capacity (95%) has a low fetal/maternal ratio (0.2 to 0.4). The extent of placental transfer is also determined by the degree of ionization and lipid solubility of the drug.
Lipid soluble, nonionized drugs readily enter the fetal blood from the maternal circulation. Depending upon the route of administration, bupivacaine is distributed to some extent to all body tissues, with high concentrations found in highly perfused organs such as the liver, lungs, heart, and brain.…
