🩺 Clinical
Amoxicillin and clavulanic acid is used to treat certain infections caused by bacteria, including infections of the ears, lungs, sinus, skin, and urinary tract. Amoxicillin is in a class of medications called penicillin-like antibiotics. It works by stopping the growth of bacteria. Clavulanic acid is in a class of medications called beta-lactamase inhibitors. It works by stopping bacteria from breaking down amoxicillin. Antibiotics will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists a...

Avoid amoxicillin and clavulanate potassium for oral suspension use in these patients. ( 5.6 ) Overgrowth: The possibility of superinfections with fungal or bacterial pathogens should be considered during therapy. ( 5.7 )
5.1Hypersensitivity Reactions Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta-lactam antibacterials, including amoxicillin and clavulanate potassium for oral suspension. These reactions are more likely to occur in individuals with a history of penicillin hypersensitivity and/or a history of sensitivity to multiple allergens. Before initiating therapy with amoxicillin and clavulanate potassium for oral suspension, careful inquiry should be made regarding previous hypersensitivity reactions to penicillins, cephalosporins, or other allergens.
If an allergic reaction occurs, amoxicillin and clavulanate potassium for oral suspension should be discontinued, and appropriate therapy instituted.
5.2Severe Cutaneous Adverse Reactions Amoxicillin and clavulanate potassium for oral suspension may cause severe cutaneous adverse reactions (SCAR), such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). If patients develop a skin rash, they should be monitored closely, and amoxicillin and clavulanate potassium for oral suspension discontinued if lesions progress.
5.3Drug-Induced Enterocolitis Syndrome (DIES) Drug-induced enterocolitis syndrome (DIES) has been reported with use of amoxicillin, a component of amoxicillin and clavulanate potassium for oral suspension [ see Adverse Reactions (6.2) ] , with most cases occurring in pediatric patients ≤ 18 years of age. DIES is a non-IgE mediated hypersensitivity reaction characterized by protracted vomiting occurring 1 to 4 hours after drug ingestion in the absence of skin or respiratory symptoms. DIES maybeassociated with pallor, lethargy, hypotension, shock, diarrhea within 24 hours of ingesting amoxicillin, and leukocytosis with neutrophilia.
If DIES occurs, discontinue amoxicillin and clavulanate potassium for oral suspension and institute appropriate therapy.
5.4Hepatic Dysfunction Hepatic dysfunction, including hepatitis and cholestatic jaundice has been associated with the use of amoxicillin and clavulanate potassium for oral suspension.

Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile. C. difficile produ…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following are discussed in more detail in other sections of the labeling: Anaphylactic reactions [see Warnings and Precautions (5.1) ] Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.2) ] Drug-Induced Enterocolitis Syndrome (DIES) [see Warnings and Precautions (5.3) ] Hepatic Dysfunction [see Warnings and Precautions (5.4) ] Clostridioides difficile Associated Diarrhea (CDAD) [see Warnings and Precautions (5.5) ] The most frequently reported adverse reactions were diarrhea/loose stools (9%), nausea (3%), skin rashes and urticaria (3%), vomiting (1%) and vaginitis (1%).
(6.1) To report SUSPECTED ADVERSE REACTIONS, contact Aurobindo Pharma USA, Inc. at 1-866-850-2876 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most frequently reported adverse reactions were diarrhea/loose stools (9%), nausea (3%), skin rashes and urticaria (3%), vomiting (1%) and vaginitis (1%). Less than 3% of patients discontinued therapy because of drug-related adverse reactions.
The overall incidence of adverse reactions, and in particular diarrhea, increased with the higher recommended dose. Other less frequently reported adverse reactions (less than 1%) include: Abdominal discomfort, flatulence, and headache. In pediatric patients (aged 2 months to 12 years), 1 U.S./Canadian clinical trial was conducted which compared 45/6.4 mg/kg/day (divided every 12 hours) of amoxicillin and clavulanate potassium for oral suspension for 10 days versus 40/10 mg/kg/day (divided every 8 hours) of amoxicillin and clavulanate potassium for oral suspension for 10 days in the treatment of acute otitis media.
A total of 575 patients were enrolled, and only the suspension formulations were used in this trial. Overall, the adverse reactions seen were comparable to that noted above; however, there were differences in the rates of diarrhea, skin rashes/urticaria, and diaper area rashes [see Clinical Studies (14.2) ] .
6.2Postmarketing Experience In addition to adverse reactions reported from clinical trials, the following have been identified during postmarketing use of amoxicillin and clavulanate potassium for oral suspension. 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 of reporting, or potential causal connection to amoxicillin and clavulanate potassium for oral suspension.
Gastrointestinal: Drug-induced enterocolitis syndrome (DIES), indigestion, gastritis, stomatitis, glossitis, black “hairy” tongue, mucocutaneous candidiasis, enterocolitis, and hemorrhagic/pseudomembranous colitis. Onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment [see Warnings and Precautions (5.5) ] . Immune: Hypersensitivity reactions, anaphylactic/anaphylactoid reactions (including shock), angioedema, serum sickness-like reactions (urticaria or skin rash accompanied by arthritis, arthralgia, myalgia, and frequently fever), hypersensitivity vasculitis [see Warnings and Precautions (5.1) ].
Skin and Appendages: Rashes, pruritus, urticaria, erythema multiforme, SJS, TEN, DRESS, AGEP, exfoliative dermatitis, and linear IgA bullous dermatosis. Liver: Hepatic dysfunction, including hepatitis and cholestatic jaundice, increases in serum transaminases (AST and/or ALT), serum bilirubin, and/or alkaline phosphatase, has been reported with amoxicillin and clavulanate potassium for oral suspension. It has been reported more commonly in the elderly, in males, or in patients on prolonged treatment.
The histologic findings on liver biopsy have consisted of predominantly cho…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Co-administration with probenecid is not recommended. (7.1) Concomitant use of amoxicillin and clavulanate potassium for oral suspension and oral anticoagulants may increase the prolongation of prothrombin time. (7.2) Co-administration with allopurinol increases the risk of rash. (7.3) Amoxicillin and clavulanate potassium for oral suspension may reduce efficacy of oral contraceptives. (7.4)
7.1Probenecid Probenecid decreases the renal tubular secretion of amoxicillin but does not delay renal excretion of clavulanic acid. Concurrent use with amoxicillin and clavulanate potassium for oral suspension may result in increased and prolonged blood concentrations of amoxicillin. Co-administration of probenecid is not recommended.
7.2Oral Anticoagulants Abnormal prolongation of prothrombin time (increased international normalized ratio [INR]) has been reported in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken when anticoagulants are prescribed concurrently with amoxicillin and clavulanate potassium for oral suspension. Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation.
7.3Allopurinol The concurrent administration of allopurinol and amoxicillin increases the incidence of rashes in patients receiving both drugs as compared to patients receiving amoxicillin alone. It is not known whether this potentiation of amoxicillin rashes is due to allopurinol or the hyperuricemia present in these patients.
7.4Oral Contraceptives Amoxicillin and clavulanate potassium for oral suspension may affect intestinal flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives.
7.5Effects on Laboratory Tests High urine concentrations of amoxicillin may result in false-positive reactions when testing for the presence of glucose in urine using CLINITEST ® , Benedict’s Solution, or Fehling’s Solution. Since this effect may also occur with amoxicillin and clavulanate potassium for oral suspension, it is recommended that glucose tests based on enzymatic glucose oxidase reactions be used. Following administration of amoxicillin to pregnant women, a transient decrease in plasma concentration of total conjugated estriol, estriol-glucuronide, conjugated estrone, and estradiol has been noted.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pediatric Use: Modify dose in patients 12 weeks or younger. (8.4) Renal Impairment: Dosage adjustment is recommended for severe renal impairment (GFR less than 30 mL/min). ( 2.4 , 8.6)
8.1Pregnancy Teratogenic Effects : Pregnancy Category B. Reproduction studies performed in pregnant rats and mice given amoxicillin and clavulanate potassium for oral suspension (2:1 ratio formulation of amoxicillin:clavulanate) at oral doses up to 1200 mg/kg/day revealed no evidence of harm to the fetus due to amoxicillin and clavulanate potassium for oral suspension. The amoxicillin doses in rats and mice (based on body surface area) were approximately 4 and 2 times the maximum recommended adult human oral dose (875 mg every 12 hours).
For clavulanate, these dose multiples were approximately 9 and 4 times the maximum recommended adult human oral dose (125 mg every 8 hours). There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
8.2Labor and Delivery Oral ampicillin-class antibacterials are poorly absorbed during labor. It is not known whether use of amoxicillin and clavulanate potassium in humans during labor or delivery has immediate or delayed adverse effects on the fetus, prolongs the duration of labor, or increases the likelihood of the necessity for an obstetrical intervention.
8.3Nursing Mothers Amoxicillin has been shown to be excreted in human milk. Amoxicillin and clavulanate potassium use by nursing mothers may lead to sensitization of infants. Caution should be exercised when amoxicillin and clavulanate potassium is administered to a nursing woman.
8.4Pediatric Use The safety and effectiveness of amoxicillin and clavulanate potassium for oral suspension and chewable tablets have been established in pediatric patients. Use of amoxicillin and clavulanate potassium for oral suspension in pediatric patients is supported by evidence from studies of amoxicillin and clavulanate potassium tablets in adults with additional data from a study of amoxicillin and clavulanate potassium for oral suspension in pediatric patients aged 2 months to 12 years with acute otitis media [see Clinical Studies (14.2) ] .
Because of incompletely developed renal function in neonates and young infants, the elimination of amoxicillin may be delayed; clavulanate elimination is unaltered in this age group. Dosing of amoxicillin and clavulanate potassium for oral suspension should be modified in pediatric patients aged less than 12 weeks (less than 3 months) [see Dosage and Administration (2.3) ] .
8.5Geriatric Use Of the 3,119 patients in an analysis of clinical studies of amoxicillin and clavulanate potassium for oral suspension, 32% were greater than or equal to 65 years old, and 14% were greater than or equal to 75 years old. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
This drug 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.
8.6Renal Impairment Amoxicillin is primarily eliminated by the kidney and dosage adjustment is usually required in patients with severe renal impairment (GFR less than 30 mL/min). See Patients with Renal Impairment [see Dosage and Administration (2.4) ] for specific recommendations in patients with renal impairment.

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.
🆘 Overdosage ▾
10 OVERDOSAGE In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures as required. A prospective study of 51 pediatric patients at a poison-control center suggested that overdosages of less than 250 mg/kg of amoxicillin are not associated with significant clinical symptoms 1 . Interstitial nephritis resulting in oliguric renal failure has been reported in patients after overdosage with amoxicillin and clavulanate potassium.
Crystalluria, in some cases leading to renal failure, has also been reported after amoxicillin and clavulanate potassium overdosage in adult and pediatric patients. In case of overdosage, adequate fluid intake and diuresis should be maintained to reduce the risk of amoxicillin and clavulanate potassium crystalluria. Renal impairment appears to be reversible with cessation of drug administration.
High blood levels may occur more readily in patients with impaired renal function because of decreased renal clearance of amoxicillin and clavulanate potassium. Amoxicillin and clavulanate potassium may be removed from circulation by hemodialysis [see Dosage and Administration (2.4) ] .

Oral administration of 5 mL of the 250 mg/62.5 mg suspension of amoxicillin and clavulanate potassium or the equivalent dose of 10 mL of the 125 mg/31.25 mg suspension of amoxicillin and clavulanate potassium provides average peak serum concentrations approximately 1 hour after dosing of 6.9 mcg/mL for amoxicillin and 1.6 mcg/mL for clavulanic acid. The areas under the serum concentration curves obtained during the first 4 hours after dosing were 12.6 mcg * h/mL for amoxicillin and 2.9 mcg * h/mL for clavulanic acid when 5 mL of the 250 mg/62.5 mg suspension of amoxicillin and clavulanate potassium or equivalent dose of 10 mL of the 125 mg/31.25 mg suspension of amoxicillin and clavulanate potassium were administered to normal adults.
One 250 mg/62.5 mg chewable tablet of amoxicillin and clavulanate potassium or two 125 mg/31.25 mg chewable tablets of amoxicillin and clavulanate potassium are equivalent to 5 mL of the 250 mg/62.5 mg suspension of amoxicillin and clavulanate potassium and provide similar serum concentrations of amoxicillin and clavulanic acid. Amoxicillin serum concentrations achieved with amoxicillin and clavulanate potassium are similar to those produced by the oral administration of equivalent doses of amoxicillin alone. Time above the minimum inhibitory concentration of 1 mcg/mL for amoxicillin has been shown to be similar after corresponding every 12 hour and every 8-hour dosing regimens of amoxicillin and clavulanate potassium in adults and children.
Absorption : Dosing in the fasted or fed state has minimal effect on the pharmacokinetics of amoxicillin. While amoxicillin and clavulanate potassium can be given without regard to meals, absorption of clavulanate potassium when taken with food is greater relative to the fasted state. In one study, the relative bioavailability of clavulanate was reduced when amoxicillin and…

📋 Description ▾
11 DESCRIPTION Amoxicillin and clavulanate potassium for oral suspension, USP is an oral antibacterial combination consisting of amoxicillin and the beta-lactamase inhibitor, clavulanate potassium (the potassium salt of clavulanic acid). Amoxicillin USP is an analog of ampicillin, derived from the basic penicillin nucleus, 6-aminopenicillanic acid. The amoxicillin molecular formula is C 16 H 19 N 3 O 5 S•3H 2 O, and the molecular weight is 419.46.
Chemically, amoxicillin is (2 S, 5 R, 6 R )-6-[( R )-(-)-2-Amino-2-( p- hydroxyphenyl)acetamido]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid trihydrate and may be represented structurally as: Clavulanic acid is produced by the fermentation of Streptomyces clavuligerus . It is a beta-lactam structurally related to the penicillins and possesses the ability to inactivate some beta-lactamases by blocking the active sites of these enzymes. The clavulanate potassium molecular formula is C 8 H 8 KNO 5 , and the molecular weight is 237.25.
Chemically, clavulanate potassium is potassium ( Z )(2 R, 5 R )-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo[3.2.0]-heptane-2-carboxylate and may be represented structurally as: 200 mg/28.5 mg: Following constitution, each 5 mL of oral suspension contains 200 mg of amoxicillin as the trihydrate, and 28.5 mg of clavulanic acid (equivalent to 34 mg of clavulanate potassium). 400 mg/57 mg: Following constitution, each 5 mL of oral suspension contains 400 mg of amoxicillin as the trihydrate, and 57 mg of clavulanic acid (equivalent to 68 mg of clavulanate potassium).

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Administration Instructions Inform patients that amoxicillin and clavulanate potassium for oral suspension may be taken every 8 hours or every 12 hours, depending on the dose prescribed. Each dose should be taken with a meal or snack to reduce the possibility of gastrointestinal upset. Allergic Reactions Counsel patients that amoxicillin and clavulanate potassium for oral suspension contains a penicillin class drug product that can cause allergic reactions in some individuals.
Severe Cutaneous Adverse Reactions (SCAR ) Advise patients about the signs and symptoms of serious skin manifestations. Instruct patients to stop taking amoxicillin and clavulanate potassium for oral suspension immediately and promptly report the first signs or symptoms of skin rash, mucosal lesions, or any other sign of hypersensitivity [see Warnings and Precautions (5.2) ] . Diarrhea Counsel patients that diarrhea is a common problem caused by antibacterials, and it usually ends when the antibacterial is discontinued.
Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken their last dose of the antibacterial. If diarrhea is severe or lasts more than 2 or 3 days, patients should contact their physician as soon as possible. Antibacterial Resistance Patients should be counseled that antibacterial drugs, including amoxicillin and clavulanate potassium for oral suspension, should only be used to treat bacterial infections.
They do not treat viral infections (e.g., the common cold). When amoxicillin and clavulanate potassium for oral suspension is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may: (1) decrease the effectiveness of the immediate treatment, and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by amoxicillin and clavulanate potassium for oral suspension or other antibacterial drugs in the future.
Storage Instructions Advise patients to keep suspension refrigerated. Shake well before using. When dosing a child with the suspension (liquid) of amoxicillin and clavulanate potassium for oral suspension, use a calibrated oral syringe.
Be sure to rinse the calibrated oral syringe after each use. Bottles of suspension of amoxicillin and clavulanate potassium for oral suspension may contain more liquid than required. Follow your doctor’s instructions about the amount to use and the days of treatment your child requires.
