Beta-lactam antibiotic (aminopenicillin)
1 INDICATIONS AND USAGE Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is indicated for the treatment of pediatric patients aged 3 months to 12 years weighing less than or equal to 40 kg with: Recurrent or persistent acute otitis media due to S. pneumoniae (penicillin MICs less than or equal to 2 mcg/mL), H. influenzae (including beta-lactamase-producing strains), or M. catarrhalis (including beta-lactamase-producing strains) characterized by the following risk factors: Antibacterial drug exposure for acute otitis media within the preceding 3 months, and either of the following: 1) age 2 years, or younger or 2) day care attendance [see Microbiology (12.4) ] . Limitations of Use Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is not indicated for the treatment of acute otitis media due to S. pneumoniae with penicillin MIC greater than or equal to 4 mcg/mL. Acute otitis media due to S. pneumoniae alone can be treated with amoxicillin. Therapy may be instituted prior to obtaining the results from bacteriological studies when there is reason to believe the infection may involve both S . pneumoniae (penicillin MIC less than or equal to 2 mcg/mL) and the beta-lactamase-producing organisms listed above. Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL and other antibacterial drugs, amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL 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. Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is a combination of amoxicillin, a penicillin-class antibacterial and clavulanate potassium, a beta-lactamase inhibitor, indicated for the treatment of pediatric patients aged 3 months to 12 years weighing less than or equal to 40 kg with Recurrent or persistent acute otitis media due to S. pneumoniae (penicillin MICs less than or equal to 2 mcg/mL), H. influenzae (including beta-lactamase-producing strains), or M. catarrhalis (including beta-lactamase-producing strains) characterized by the following risk factors (1): Antibacterial exposure for acute otitis media within the preceding 3 months, and either of the following: 1) age 2 years, or younger or 2) daycare attendance. Limitations of Use Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is not indicated for the treatment of acute otitis media due to S. pneumoniae with penicillin MIC greater than or equal to 4 mcg/mL. Acute otitis media due to S. pneumoniae alone can be treated with amoxicillin. Therapy may be instituted prior to obtaining the results from bacteriological studies when there is reason to believe the infection may involve both S. pneumoniae (penicillin MIC less than or equal to 2 mcg/mL) and the beta-lactamase-producing organisms listed above.

3 months to 12 years weighing less than or equal to 40 kg: 90 mg/kg/day divided every 12 hours, administered for 10 days. ( 2 ) 2.1 Important Administration Instructions To minimize the potential for gastrointestinal intolerance, amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL should be taken at the start of a meal. Absorption of clavulanate potassium may be enhanced when amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is administered at the start of a meal. 2.2 Dosage in Pediatric Patients Pediatric patients aged 3 months to 12 years weighing less than or equal to 40 kg : Based on the amoxicillin component (600 mg/5 mL), the recommended dose of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL is 90 mg/kg/day divided every 12 hours, administered for 10 days (see Table 1 as a general example guideline for attainment of this dosage). This dose provides 6.4 mg/kg/day of the clavulanic acid component. Table 1: General Dosage Guidelines for Amoxicillin and Clavulanate Potassium for Oral Suspension, 600 mg/42.9 mg per 5 mL in Pediatric Patients Body Weight (kg) Volume of Amoxicillin and Clavulanate Potassium for Oral Suspension, 600 mg/42.9 mg per 5 mL providing 90 mg/kg/day 8 3 mL twice daily 12 4.5 mL twice daily 16 6 mL twice daily 20 7.5 mL twice daily 24 9 mL twice daily 28 10.5 mL twice daily 32 12 mL twice daily 36 13.5 mL twice daily 40 15 mL twice daily Pediatric patients weighing greater than 40 kg : Experience with amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL in this group is not available. 2.3 Dosage in Adult Patients Experience with amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL in adults is not available and adults who have difficulty swallowing should not be given amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL in place of the amoxicillin and clavulanate potassium 500 mg or 875 mg tablet. 2.4 Dosage in Patients with Hepatic Impairment Hepatically impaired patients should be dosed with caution and hepatic function monitored at regular intervals [see Warnings and Precautions (5.4) ]. 2.5 Preparation of the Oral Suspension Prepare the suspension at time of dispensing as follows: Tap bottle until all powder flows freely. Measure the total amount of water (see Table 2) to be added in two parts. Add approximately 2/3 of the total amount of water for reconstitution, replace cap and shake vigorously to suspend powder. Add remainder of the water (that had been measured), replace cap and again shake vigorously. Table 2: Volume of Water for Reconstituting Amoxicillin and Clavulanate Potassium for Oral Suspension, 600 mg/42.9 mg per 5 mL Bottle Size Amount of Water Required for Reconstitution 75 mL 68 mL 125 mL 108 mL 200 mL 170 mL Each 5 mL will contain 600 mg of amoxicillin as the trihydrate, and 42.9 mg of clavulanic acid as the potassium salt. Shake oral suspension well before each use. Suspension must be refrigerated. Discard after 10 days. Suspension is off-white at time of reconstitution; some color change is normal during the dosing period. Flavoring Information : For patients who wish to alter the taste of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL, immediately after reconstitution, 1 drop of FLAVORx ® (apple, banana cream, bubble gum, cherry, or watermelon flavor) may be added for every 5 mL of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL. The resulting suspension is stable for 10 days under refrigeration. Stability of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL when mixed with other flavors other than the 5 flavors listed above has not been evaluated. 2.6 Switching between Dosage Forms and between Strengths Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL does not contain the same amount of clavulanic acid (as the potassium salt) as any of the other suspensions of amoxicillin and clavulanate potassium. Amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL contains 42.9 mg of clavulanic acid per 5 mL, whereas the amoxicillin and clavulanate potassium, 200 mg/28.5 mg per 5 mL suspension contains 28.5 mg of clavulanic acid per 5 mL and the 400 mg/57 mg per 5 mL suspension contains 57 mg of clavulanic acid per 5 mL. Therefore, the amoxicillin and clavulanate potassium 200 mg/28.5 mg per 5 mL and 400 mg/57 mg per 5 mL suspensions should not be substituted for amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL as they are not interchangeable.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Chartwell RX, LLC. at 1-845-232-1683 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials 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. Two clinical trials evaluated the safety of a 10-day treatment course of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL 90/6.4 mg/kg/day, divided every 12 hours, in pediatric patients with acute otitis media [see Clinical Studies (14)] . The first trial involved 521 pediatric patients (3 months to 50 months) and the second trial involved 450 pediatric patients (3 months to 12 years). In the intent-to-treat population of the first trial of 521 patients, the most frequently reported adverse events were vomiting (7%), fever (6%), contact dermatitis (i.e., diaper rash) (6%), upper respiratory tract infection (4%), and diarrhea (4%). Protocol-defined diarrhea (i.e., 3 or more watery stools in one day or 2 watery stools per day for 2 consecutive days as recorded on diary cards) occurred in 13% of patients. The primary objective of the second study was to compare the safety of amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL (90/6.4 mg/kg/day, divided every 12 hours) to amoxicillin and clavulanate potassium (45/6.4 mg/kg/day, divided every 12 hours) for ten days. There was no statistically significant difference between treatments in the proportion of patients with 1 or more adverse events. The most frequently reported adverse reactions for amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL and the comparator of amoxicillin and clavulanate potassium were coughing (12% versus 7%), vomiting (7% versus 8%), contact dermatitis (i.e., diaper rash, 6% versus 5%), fever (6% versus 4%), and upper respiratory infection (3% versus 9%), respectively. The frequencies of protocol-defined diarrhea with amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL (11%) and amoxicillin and clavulanate potassium (9%) were not statistically different. Two patients in the group treated with amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL and one patient in the group treated with amoxicillin and clavulanate potassium were withdrawn due to diarrhea. 6.2 Postmarketing Experience The following adverse reactions have been identified during postmarketing use of amoxicillin and clavulanate potassium products, including amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal: Drug-induced enterocolitis syndrome (DIES), diarrhea, nausea, vomiting, 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 ( 5.3 , 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 [see Warnings and Precautions ( 5.1 , 5.2 , 5.6 )]. Liver: A moderate rise in AST (SGOT) and/or ALT (SGPT) has been noted in patients treated with ampicillin-class antibacterials. Hepatic dysfunction, including increases in serum transaminases (AST and/or ALT), serum bilirubin, and/or alkaline phosphatase, has been infrequently reported with amoxicillin and clavulanate potassium or amoxicillin and clavulanate potassium for oral suspension, 600 mg/42.9 mg per 5 mL. 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 cholestatic, hepatocellular, or mixed cholestatic-hepatocellular changes. The onset of signs/symptoms of hepatic dysfunction may occur during or several weeks after therapy has been discontinued. The hepatic dysfunction, which may be severe, is usually reversible. Deaths have been reported [see Contraindications (4.2) , Warnings and Precautions (5.4) ]. Renal: Interstitial nephritis and hematuria have been reported. Crystalluria has also been reported [see Overdosage (10) ] . Hemic and Lymphatic Systems: Anemia, including hemolytic anemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia, and agranulocytosis have been reported during therapy with penicillins. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. There have been reports of increased prothrombin time in patients receiving amoxicillin and clavulanate potassium and anticoagulant therapy concomitantly. Central Nervous System: Agitation, anxiety, behavioral changes, aseptic meningitis, confusion, convulsions, dizziness, insomnia, and reversible hyperactivity have been reported. Miscellaneous: Tooth discoloration (brown, yellow, or gray staining) has been reported. Most reports occurred in pediatric patients. Discoloration was reduced or eliminated with brushing or dental cleaning in most cases.
