Indications and Usage

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Ampicillin and Sulbactam for Injection and other antibacterial drugs, Ampicillin and Sulbactam for Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy.

In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.Ampicillin and Sulbactam for Injection is indicated for the treatment of infections due to susceptible strains of the designated microorganisms in the conditions listed below.Skin and Skin Structure Infections caused by beta-lactamase producing strains of Staphylococcus aureus, Escherichiacoli,Efficacy for this organism in this organ system was studied in fewer than 10 infections.Klebsiella spp. (including K.pneumoniae ), Proteus mirabilis,Bacteroides fragilis ,Enterobacter spp., andAcinetobacter calcoaceticus.NOTE: For information on use in pediatric patients see PRECAUTIONS—Pediatric Use and CLINICAL STUDIES sections.Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli, Klebsiella spp.

(including K.

pneumoniae ), Bacteroides spp. (including B.

fragilis), andEnterobacter spp.Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli , and Bacteroides spp. (including B.

fragilis ).While Ampicillin and Sulbactam for Injection is indicated only for the conditions listed above, infections caused by ampicillin-susceptible organisms are also amenable to treatment with Ampicillin and Sulbactam for Injection due to its ampicillin content.

Therefore, mixed infections caused by ampicillin-susceptible organisms and beta-lactamase producing organisms susceptible to Ampicillin and Sulbactam for Injection should not require the addition of another antibiotic.Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify the organisms causing infection and to determine their susceptibility to Ampicillin and Sulbactam for Injection.Therapy may be instituted prior to obtaining the results from bacteriological and susceptibility studies, when there is reason to believe the infection may involve any of the beta-lactamase producing organisms listed above in the indicated organ systems.

Once the results are known, therapy should be adjusted if appropriate.
Infection -- Invasion of the host organism by microorganisms that can cause pathological conditions or diseases.

skin infection -- Skin diseases caused by bacteria, fungi, parasites, or viruses.

Pneumonia -- Inflammation of any part, segment or lobe, of the lung parenchyma.

Abdominal Infection --

Communicable Diseases -- broad class of diseases whose causative agents may be passed between individuals in many different ways.

Contraindications
The use of Ampicillin and Sulbactam for Injection is contraindicated in individuals with a history of hypersensitivity reactions to any of the penicillins.
Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.

Warnings

SERIOUS AND OCCASIONALLY FATAL HYPERSENSITIVITY (ANAPHYLACTIC) REACTIONS HAVE BEEN REPORTED IN PATIENTS ON PENICILLIN THERAPY.

THESE REACTIONS ARE MORE APT TO OCCUR IN INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY AND/OR HYPERSENSITIVITY REACTIONS TO MULTIPLE ALLERGENS.

THERE HAVE BEEN REPORTS OF INDIVIDUALS WITH A HISTORY OF PENICILLIN HYPERSENSITIVITY WHO HAVE EXPERIENCED SEVERE REACTIONS WHEN TREATED WITH CEPHALOSPORINS. BEFORE THERAPY WITH A PENICILLIN, CAREFUL INQUIRY SHOULD BE MADE CONCERNING PREVIOUS HYPERSENSITIVITY REACTIONS TO PENICILLINS, CEPHALOSPORINS, AND OTHER ALLERGENS.

IF AN ALLERGIC REACTION OCCURS, AMPICILLIN AND SULBACTAM FOR INJECTION SHOULD BE DISCONTINUED AND THE APPROPRIATE THERAPY INSTITUTED.SERIOUS ANAPHYLACTOID REACTIONS REQUIRE IMMEDIATE EMERGENCY TREATMENT WITH EPINEPHRINE.

OXYGEN, INTRAVENOUS STEROIDS, AND AIRWAY MANAGEMENT, INCLUDING INTUBATION, SHOULD ALSO BE ADMINISTERED AS INDICATED.Pseudomembranous colitis has been reported with nearly all antibacterial agents, including Ampicillin and Sulbactam for Injection, and has ranged in severity from mild to life-threatening.

Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents.Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia.

Studies indicate that toxin produced byClostridium difficile is one primary cause of "antibiotic-associated colitis."Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug clinically effective against C.

difficile colitis.
