📖 What it is MedlinePlus · NLM

The combination of ampicillin and sulbactam injection is used to treat certain infections caused by bacteria, including infections of the skin, female reproductive organs, and abdomen (stomach area). Ampicillin is in a class of medications called penicillin-like antibiotics. It works by stopping the growth of bacteria. Sulbactam is in a class of medications called beta-lactamase inhibitors. It works by preventing bacteria from destroying ampicillin. Antibiotics such as ampicillin and sulbactam injection will not work for colds, flu, or other viral infections. Using antibiotics when they are no...

💊 What it looks like

Color white

One label can cover several strengths, so colors may be combined — always confirm a loose pill against the dispensed prescription label or a pharmacist.

Where does this data come from?

Physical description (imprint, shape, color, scoring, coating) from this product’s FDA Structured Product Labeling (SPL), mirrored from DailyMed / openFDA.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.

Where does this data come from?

Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?

No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.

Why might an inactive ingredient be missing?

Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.

Can inactive ingredients matter?

Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price system	Per mL	Per package
Retail pharmacies payNADAC · weekly	Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo	No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · quarterly	No Part D plan price is available for this NDC in our data.

ℹ️

No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.

Where does this data come from?

NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Questions about this listing

Why is there no price listed?

The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.

Is the NDC printed on the package the same as the 11-digit billing NDC?

Yes, they identify this exact package in different formats. The FDA registers it as 83270-308-01, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 83270-0308-01, written without dashes as 83270030801. The Identity section at the top of this page lists every form of this code.

What do the three segments of this NDC mean?

In 83270-0308-01, the first segment (83270) is the labeler code FDA assigned to ONESOURCE SPECIALTY PHARMA LIMITED; the middle segment (0308) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (01) identifies this exact package size and type. Together they name one specific package of one specific product.

Is this package still being marketed?

Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by ONESOURCE SPECIALTY PHARMA LIMITED. Listing status can change — the directory data on this page refreshes weekly.

Who lists this product with the FDA?

ONESOURCE SPECIALTY PHARMA LIMITED is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.

Do I need a prescription for this product?

This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.

This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

Where does this data come from?

🎯 Indications and Usage ~2 min read ▾

INDICATIONS AND USAGE Ampicillin and Sulbactam for Injection, USP, 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 , Escherichia coli , * Klebsiella spp. * (including K. pneumoniae * ), Proteus mirabilis, * Bacteroides fragilis , * Enterobacter spp ., * and Acinetobacter 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), and Enterobacter spp.* Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli ,* and Bacteroides spp. * (including B. fragilis *). *Efficacy for this organism in this organ system was studied in fewer than 10 infections.

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 antibacterial. 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. To reduce the development of drug-resistant bacteria and maintain effectiveness of Ampicillin and Sulbactam for Injection and other antibacterial drugs, Ampicillin and Sulbactam for Injection should be used only to treat 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.

⏱️ Dosage and Administration ~3 min read ▾

DOSAGE AND ADMINISTRATION The pharmacy bulk package is for preparation of solutions for IV infusion only. Ampicillin and Sulbactam for Injection should be administered diluted with 50 mL to 100 mL of a compatible diluent as an intravenous infusion over 1530 minutes. The recommended adult dosage of Ampicillin and Sulbactam for Injection is 1.5 g (ampicillin 1 g and sulbactam 0.5 g) to 3 g (ampicillin 2 g and sulbactam 1 g) every six hours.

This 1.5 to 3 g range represents the total of ampicillin content plus the sulbactam content of Ampicillin and Sulbactam for Injection and corresponds to a range of 1 g ampicillin and 0.5 g sulbactam to 2 g ampicillin and 1 g sulbactam. The total dose of sulbactam should not exceed 4 g per day. Pediatric Patients 1 Year of Age or Older: The recommended daily dose of Ampicillin and Sulbactam for Injection in pediatric patients is 300 mg per kg of body weight administered via intravenous infusion in equally divided doses every 6 hours.

This 300 mg/kg/day dosage represents the total ampicillin content plus the sulbactam content of Ampicillin and Sulbactam for Injection, and corresponds to 200 mg ampicillin and 100 mg sulbactam per kg per day. The safety and efficacy of Ampicillin and Sulbactam for Injection administered via intramuscular injection in pediatric patients have not been established. Pediatric patients weighing 40 kg or more should be dosed according to adult recommendations, and the total dose of sulbactam should not exceed 4 g per day.

The course of intravenous therapy should not routinely exceed 14 days. In clinical trials, most most pediatric patients received a course of oral antimicrobials following initial treatment with intravenous Ampicillin and Sulbactam for Injection (see CLINICAL STUDIES section). Impaired Renal Function In patients with impairment of renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function.

The dose of Ampicillin and Sulbactam for Injection in such patients should be administered less frequently in accordance with the usual practice for ampicillin and according to the following recommendations: TABLE 3 Ampicillin and Sulbactam for Injection, USP Dosage Guide for Patients with Renal Impairment Creatinine Clearance (mL/min/1.73m 2 ) Ampicillin/Sulbactam Half-Life (Hours) Recommended Ampicillin and Sulbactam for Injection, USP Dosage 30 1 1.5 g to 3 g every 6 to 8 hours 15 - 29 5 1.5 g to 3 g every 12 hours 5 - 14 9 1.5 g to 3 g every 24 hours When only serum creatinine is available, the following formula (based on sex, weight, and age of the patient) may be used to convert this value into creatinine clearance.

The serum creatinine should represent a steady state of renal function. Males weight (kg) × (140 - age) 72 × serum creatinine Females 0.85 × above value COMPATIBILITY, RECONSTITUTION AND STABILITY When concomitant therapy with aminoglycosides is indicated, Ampicillin and Sulbactam for Injection and aminoglycosides should be reconstituted and administered separately, due to the in vitro inactivation of aminoglycosides by any of the aminopenicillins. Intravenous Administration Directions for Proper Use of Pharmacy Bulk Package General Dissolution Procedures: Ampicillin and Sulbactam for Injection sterile powder for intravenous use may be reconstituted with any of the compatible diluents described in this insert.

Solutions should be allowed to stand after dissolution to allow any foaming to dissipate in order to permit visual inspection for complete solubilization. Reconstituted Bulk Solution Should Not be Used For Direct Infusion Prior to intravenous administration, Ampicillin and Sulbactam for Injection must be reconstituted and further diluted before use. a) Reconstitute the 15 g vial with either 92 mL Sterile Water for Injection or 0.9% Sodium Chloride Injection, added in two separate aliquots in a suitable work area, such as a lami…

⛔ Contraindications 62 words ▾

CONTRAINDICATIONS The use of Ampicillin and Sulbactam for injection is contraindicated in individuals with a history of serious hypersensitivity reactions (e.g., anaphylaxis or Stevens-Johnson syndrome) to ampicillin, sulbactam or to other beta-lactam antibacterial drugs (e.g., penicillins and cephalosporins). Ampicillin and Sulbactam for injection is contraindicated in patients with a previous history of cholestatic jaundice/hepatic dysfunction associated with Ampicillin and Sulbactam for injection.

⚠️ Warnings ~2 min read ▾

WARNINGS Hypersensitivity 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. Hepatotoxicity Hepatic dysfunction, including hepatitis and cholestatic jaundice has been associated with the use of Ampicillin and Sulbactam for injection.

Hepatic toxicity is usually reversible; however, deaths have been reported. Hepatic function should be monitored at regular intervals in patients with hepatic impairment. Severe Cutaneous Adverse Reactions Ampicillin and Sulbactam for injection may cause severe skin reactions, such as toxic epidermal necrolysis (TEN), Stevens Johnson syndrome (SJS), drug reaction with eosinophilia and systemic symptoms (DRESS), dermatitis exfoliative, erythema multiforme, and Acute generalized exanthematous pustulosis (AGEP).

If patients develop a skin rash they should be monitored closely and Ampicillin and Sulbactam for injection discontinued if lesions progress (see CONTRAINDICATIONS and ADVERSE REACTIONS sections). Clostridioides difficile -Associated Diarrhea Clostridioides difficile- associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Ampicillin and Sulbactam for Injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile .

C.difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C.difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use.

Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C.difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C.difficile , and surgical evaluation should be instituted as clinically indicated.

🤒 Adverse Reactions ~2 min read ▾

ADVERSE REACTIONS Adult Patients: Ampicillin and Sulbactam for Injection is generally well tolerated. The following adverse reactions have been reported in clinical trials. Local Adverse Reactions Pain at IM injection site - 16% Pain at IV injection site - 3% Thrombophlebitis - 3% Phlebitis – 1.2% Systemic Adverse Reactions The most frequently reported adverse reactions were diarrhea in 3% of the patients and rash in less than 2% of the patients.

Additional systemic reactions reported in less than 1% of the patients were: itching, nausea, vomiting, candidiasis, fatigue, malaise, headache, chest pain, flatulence, abdominal distension, glossitis, urine retention, dysuria, edema, facial swelling, erythema, chills, tightness in throat, substernal pain, epistaxis and mucosal bleeding. Pediatric Patients: Available safety data for pediatric patients treated with Ampicillin and Sulbactam for Injection demonstrate a similar adverse events profile to those observed in adult patients.

Additionally, atypical lymphocytosis has been observed in one pediatric patient receiving Ampicillin and Sulbactam for Injection. Adverse Laboratory Changes Adverse laboratory changes without regard to drug relationship that were reported during clinical trials were: Hepatic : Increased AST (SGOT), ALT (SGPT), alkaline phosphatase, and LDH. Hematologic : Decreased hemoglobin, hematocrit, RBC, WBC, neutrophils, lymphocytes, platelets and increased lymphocytes, monocytes, basophils, eosinophils, and platelets.

Blood Chemistry : Decreased serum albumin and total proteins. Renal : Increased BUN and creatinine. Urinalysis : Presence of RBC’s and hyaline casts in urine.

Postmarketing Experience In addition to adverse reactions reported from clinical trials, the following have been identified during post-marketing use of ampicillin sodium and sulbactam sodium or other products containing ampicillin. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency, or potential causal connection to ampicillin sodium and sulbactam sodium.

Infections and Infestations: Clostridioides difficile- associated diarrhea (see WARNINGS section). Blood and Lymphatic System Disorders: Hemolytic anemia, thrombocytopenic purpura, and agranulocytosis have been reported. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena.

Some individuals have developed positive direct Coombs Tests during treatment with Ampicillin and Sulbactam for injection, as with other beta-lactam antibacterials. Gastrointestinal Disorders: Abdominal pain, cholestatic hepatitis, cholestasis, hyperbilirubinemia, jaundice, abnormal hepatic function, melena, gastritis, stomatitis, dyspepsia, and black “hairy” tongue (see CONTRAINDICATIONS and WARNINGS sections). General Disorders and Administration Site Conditions: Injection site reaction Immune System Disorders: Serious and fatal hypersensitivity (anaphylactic) reactions (See WARNINGS section), Acute myocardial ischemia with or without myocardial infarction may occur as part of an allergic reaction.

Metabolism and Nutrition Disorders: Hypokalemia Nervous System Disorders: Convulsion and dizziness. Renal and Urinary Disorders: Tubulointerstitial nephritis. Musculoskeletal and Connective Tissue Disorders: Arthralgia Respiratory, Thoracic and Mediastinal Disorders: Dyspnea Skin and Subcutaneous Tissue Disorders: Toxic epidermal necrolysis, Stevens-Johnson syndrome, drug reaction with eosinophilia and systemic symptoms (DRESS),angioedema, Acute generalised exanthematous pustulosis (AGEP), erythema multiforme, exfoliative dermatitis, urticaria (see CONTRAINDICATIONS and WARNINGS sections), and linear IgA bullous dermatosis.

🆘 Overdosage 47 words ▾

OVERDOSAGE Neurological adverse reactions, including convulsions, may occur with the attainment of high CSF levels of beta-lactams. Ampicillin may be removed from circulation by hemodialysis. The molecular weight, degree of protein binding and pharmacokinetics profile of sulbactam suggest that this compound may also be removed by hemodialysis.

🧬 Clinical Pharmacology ~2 min read ▾

CLINICAL PHARMACOLOGY General: Immediately after completion of a 15-minute intravenous infusion of Ampicillin and Sulbactam for Injection, peak serum concentrations of ampicillin and sulbactam are attained. Ampicillin serum levels are similar to those produced by the administration of equivalent amounts of ampicillin alone. Peak ampicillin serum levels ranging from 109 to 150 mcg/mL are attained after administration of 2000 mg of ampicillin plus 1000 mg sulbactam and 40 to 71 mcg/mL after administration of 1000 mg ampicillin plus 500 mg sulbactam.

The corresponding mean peak serum levels for sulbactam range from 48 to 88 mcg/mL and 21 to 40 mcg/mL, respectively. After an intramuscular injection of 1000 mg ampicillin plus 500 mg sulbactam, peak ampicillin serum levels ranging from 8 to 37 mcg/mL and peak sulbactam serum levels ranging from 6 to 24 mcg/mL are attained. The mean serum half-life of both drugs is approximately 1 hour in healthy volunteers.

Approximately 75 to 85% of both ampicillin and sulbactam are excreted unchanged in the urine during the first 8 hours after administration of Ampicillin and Sulbactam for Injection to individuals with normal renal function. Somewhat higher and more prolonged serum levels of ampicillin and sulbactam can be achieved with the concurrent administration of probenecid. In patients with impaired renal function the elimination kinetics of ampicillin and sulbactam are similarly affected, hence the ratio of one to the other will remain constant whatever the renal function.

The dose of Ampicillin and Sulbactam for Injection in such patients should be administered less frequently in accordance with the usual practice for ampicillin (see DOSAGE and ADMINISTRATION section). Ampicillin has been found to be approximately 28% reversibly bound to human serum protein and sulbactam approximately 38% reversibly bound. The following average levels of ampicillin and sulbactam were measured in the tissues and fluids listed: TABLE 1 Concentration of Ampicillin and Sulbactam in Various Body Tissues and Fluids Fluid or Tissue Dose (grams) Ampicillin/Sulbactam Concentration (mcg/mL or mcg/g) Ampicillin/Sulbactam Peritoneal Fluid 0.5/0.5 IV 7/14 Blister Fluid (Cantharides) 0.5/0.5 IV 8/20 Tissue Fluid 1/0.5 IV 8/4 Intestinal Mucosa 0.5/0.5 IV 11/18 Appendix 2/1 IV 3/40 Penetration of both ampicillin and sulbactam into cerebrospinal fluid in the presence of inflamed meninges has been demonstrated after IV administration of Ampicillin and Sulbactam for Injection.

The pharmacokinetics of ampicillin and sulbactam in pediatric patients receiving Ampicillin and Sulbactam for Injection are similar to those observed in adults. Immediately after a 15-minute infusion of 50 to 75 mg Ampicillin and Sulbactam for Injection/kg body weight, peak serum and plasma concentrations of 82 to 446 mcg ampicillin/mL and 44 to 203 mcg sulbactam/mL were obtained. Mean half-life values were approximately 1 hour.
