WARNINGS Serious Neurologic Adverse Reactions with Epidural Administration Serious neurologic events, some resulting in death, have been reported with epidural injection of corticosteroids.

Specific events reported include, but are not limited to, spinal cord infarction, paraplegia, quadriplegia, cortical blindness, and stroke.

These serious neurologic events have been reported with and without use of fluoroscopy.

The safety and effectiveness of epidural administration of corticosteroids have not been established, and corticosteroids are not approved for this use.

General This product contains benzyl alcohol, which is potentially toxic when administered locally to neural tissue.

Exposure to excessive amounts of benzyl alcohol has been associated with toxicity (hypotension, metabolic acidosis), particularly in neonates, and an increased incidence of kernicterus, particularly in small preterm infants.

There have been rare reports of deaths, primarily in preterm infants, associated with exposure to excessive amounts of benzyl alcohol.

The amount of benzyl alcohol in medications is usually considered negligible compared to that received in flush solutions containing benzyl alcohol.

Administration of high dosages of medications containing this preservative must take into account the total amount of benzyl alcohol administered.

The amount of benzyl alcohol at which toxicity may occur is not known.

If the patient requires more than the recommended dosages or other medications containing this preservative, the practitioner must consider the daily metabolic load of benzyl alcohol from these combined sources (see PRECAUTIONS: Pediatric Use ).

Multidose use of Methylprednisolone acetate Sterile Aqueous Suspension from a single vial requires special care to avoid contamination.

Although initially sterile, any multidose use of vials may lead to contamination unless strict aseptic technique is observed.

Particular care, such as use of disposable sterile syringes and needles, is necessary.

Injection of Methylprednisolone acetate injectable suspension may result in dermal and/or subdermal changes, forming depressions in the skin at the injection site.

In order to minimize the incidence of dermal and subdermal atrophy, care must be exercised not to exceed recommended doses in injections.

Multiple small injections into the area of the lesion should be made whenever possible.

The technique of intra-articular and intramuscular injection should include precautions against injection or leakage into the dermis.

Injection into the deltoid muscle should be avoided because of a high incidence of subcutaneous atrophy.

It is critical that, during administration of Methylprednisolone acetate injectable suspension, appropriate technique be used and care taken to ensure proper placement of drug.

Rare instances of anaphylactoid reactions have occurred in patients receiving corticosteroid therapy.

Increased dosage of rapidly acting corticosteroids is indicated in patients on corticosteroid therapy subjected to any unusual stress before, during, or after the stressful situation (see ADVERSE REACTIONS ).

Results from one multicenter, randomized, placebo-controlled study with methylprednisolone hemisuccinate, an IV corticosteroid, showed an increase in early (at 2 weeks) and late (at 6 months) mortality in patients with cranial trauma who were determined not to have other clear indications for corticosteroid treatment.

High doses of systemic corticosteroids, including Methylprednisolone acetate injectable suspension, should not be used for the treatment of traumatic brain injury.

Cardio-renal Average and large doses of corticosteroids can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium.

These effects are less likely to occur with the synthetic derivatives except when used in large doses.

Dietary salt restriction and potassium supplementation may be necessary.

All corticosteroids increase calcium excretion.

Literature reports suggest an apparent association between the use of corticosteroids and left ventricular free wall rupture after a recent myocardial infarction; therefore, therapy with corticosteroids should be used with great caution in these patients.

Endocrine Hypothalamic-pituitary adrenal (HPA) axis suppression, Cushing’s syndrome, and hyperglycemia: Monitor patients for these conditions with chronic use.

Corticosteroids can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment.

Drug induced secondary adrenocortical insufficiency may be minimized by gradual reduction of dosage.

This type of relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted.

Infections General Persons who are on corticosteroids are more susceptible to infections than are healthy individuals.

There may be decreased resistance and inability to localize infection when corticosteroids are used.

Infections with any pathogen (viral, bacterial, fungal, protozoan, or helminthic) in any location of the body may be associated with the use of corticosteroids alone or in combination with other immunosuppressive agents.

These infections may be mild, but can be severe and at times fatal.

With increasing doses of corticosteroids, the rate of occurrence of infectious complications increases.

Corticosteroids may mask some signs of current infection.

Do not use intra-articularly, intrabursally, or for intratendinous administration for local effect in the presence of acute local infection.

Fungal Infections Corticosteroids may exacerbate systemic fungal infections and therefore should not be used in the presence of such infections unless they are needed to control drug reactions.

There have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure (see CONTRAINDICATIONS and PRECAUTIONS: Drug Interactions , Amphotericin B injection and potassium-depleting agents ).

Special Pathogens Latent disease may be activated or there may be an exacerbation of intercurrent infections due to pathogens, including those caused by Amoeba, Candida, Cryptococcus, Mycobacterium, Nocardia, Pneumocystis, and Toxoplasma.

It is recommended that latent amebiasis or active amebiasis be ruled out before initiating corticosteroid therapy in any patient who has spent time in the tropics or in any patient with unexplained diarrhea.

Similarly, corticosteroids should be used with great care in patients with known or suspected Strongyloides (threadworm) infestation.

In such patients, corticosteroid- induced immunosuppression may lead to Strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia.

Corticosteroids should not be used in cerebral malaria.

There is currently no evidence of benefit from steroids in this condition.

Tuberculosis The use of corticosteroids in active tuberculosis should be restricted to those cases of fulminating or disseminated tuberculosis in which the corticosteroid is used for the management of the disease in conjunction with an appropriate antituberculous regimen.

If corticosteroids are indicated in patients with latent tuberculosis or tuberculin reactivity, close observation is necessary, as reactivation of the disease may occur.

During prolonged corticosteroid therapy, these patients should receive chemoprophylaxis.

Vaccinations Administration of live or live, attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids.

Killed or inactivated vaccines may be administered.

However, the response to such vaccines cannot be predicted.

Immunization procedures may be undertaken in patients who are receiving corticosteroids as replacement therapy (e.g., for Addison’s disease).

Viral Infections Chicken pox and measles can have a more serious or even fatal course in pediatric and adult patients on corticosteroids.

In pediatric and adult patients who have not had these diseases, particular care should be taken to avoid exposure.

The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known.

If exposed to chicken pox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated.

If exposed to measles, prophylaxis with immunoglobulin (IG) may be indicated.

(See the respective package inserts for complete VZIG and IG prescribing information.) If chicken pox develops, treatment with antiviral agents should be considered.

Ophthalmic Use of corticosteroids may produce posterior subcapsular cataracts, glaucoma with possible damage to the optic nerves, and may enhance the establishment of secondary ocular infections due to bacteria, fungi, or viruses.

The use of systemic corticosteroids is not recommended in the treatment of optic neuritis and may lead to an increase in the risk of new episodes.

Corticosteroids should be used cautiously in patients with ocular herpes simplex because of corneal perforation.

Corticosteroids should not be used in active ocular herpes simplex.

Warnings For external use only.

Do not use in the eyes longer than 1 week unless directed by a physician on individuals who are allergic or sensitive to iodine or apply over large areas of the body Stop use and ask a doctor if irritation and redness develop condition persists for more than 72 hours in case of deep or puncture wounds, animal bites or serious burns Keep out of reach of children.

If swallowed, get medical assistance or immediately contact a Poison Control Center.

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 Injection 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.

Most common adverse reactions are related to the central nervous system and the cardiovascular system.

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 total dose administered.

In a survey of studies of epidural anesthesia, overt toxicity progressing to convulsions occurred in approximately 0.1% of local anesthetic administrations.

The incidences of adverse neurologic reactions associated with the use of local anesthetics may be related to the total dose of local anesthetic administered and are also dependent upon the particular drug used, the route of administration, and the physical status of the patient.

Cardiac Disorders High doses or unintentional intravascular injection have led to high plasma levels and related depression of the myocardium, decreased cardiac output, heartblock, hypotension, bradycardia, ventricular arrhythmias, including ventricular tachycardia and ventricular fibrillation, and cardiac arrest [see Warnings and Precautions (5.9) ].

Immune System Disorders Allergic-type reactions have occurred as a result of sensitivity to bupivacaine or to other formulation ingredients, such as the antimicrobial preservative methylparaben contained in multiple-dose vials or sulfites in epinephrine-containing solutions.

These reactions were characterized by signs such as urticaria, pruritus, erythema, angioneurotic edema (including laryngeal edema), tachycardia, sneezing, nausea, vomiting, dizziness, syncope, excessive sweating, elevated temperature, and severe hypotension.

Cross sensitivity among members of the amide-type local anesthetic group has been reported [see Warnings and Precautions (5.8) ] .
