🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE To reduce the development of drug-resistant bacteria and maintain the effectiveness of amoxicillin and clavulanate potassium for oral suspension, USP and other antibacterial drugs, amoxicillin and clavulanate potassium for oral suspension, USP 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.
Amoxicillin and clavulanate potassium for oral suspension, USP is indicated for the treatment of pediatric patients with recurrent or persistent acute otitis media due to S. pneumoniae (penicillin MICs ≤ 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: -age 2 years or younger -daycare attendance [see CLINICAL PHARMACOLOGY , Microbiology (12.4) ] NOTE: Acute otitis media due to S. pneumoniae alone can be treated with amoxicillin.
Amoxicillin and clavulanate potassium for oral suspension, USP is not indicated for the treatment of acute otitis media due to S. pneumoniae with penicillin MIC ≥ 4 mcg/mL. 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 ≤ 2 mcg/mL) and the beta-lactamase-producing organisms listed above. Amoxicillin and clavulanate potassium for oral suspension, USP is indicated for the treatment of pediatric patients with recurrent or persistent acute otitis media due to S. pneumoniae (penicillin MICs ≤ 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 drug exposure for acute otitis media within the preceding 3 months, and either of the following: 1) age 2 years or younger 2) daycare attendance
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Amoxicillin and clavulanate potassium for oral suspension 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 contains 42.9 mg of clavulanic acid per 5 mL, whereas the 200 mg/5 mL suspension of amoxicillin and clavulanate potassium contains 28.5 mg of clavulanic acid per 5 mL and the 400 mg/5 mL suspension contains 57 mg of clavulanic acid per 5 mL.
Therefore, the 200 mg/28.5 mg/5 mL and 400 mg/57 mg/5 mL suspensions of amoxicillin and clavulanate potassium should not be substituted for amoxicillin and clavulanate potassium for oral suspension as they are not interchangeable. Dosage: Pediatric patients 3 months and older: Based on the amoxicillin component (600 mg/5 mL), the recommended dose of amoxicillin and clavulanate potassium for oral suspension is 90 mg/kg/day divided every 12 hours, administered for 10 days (see chart below). This dose provides 6.4 mg/kg/day of the clavulanic acid component.

⛔ Contraindications ▾
4 CONTRAINDICATIONS • History of a serious hypersensitivity reaction (e.g., anaphylaxis or Stevens-Johnson syndrome) to amoxicillin and clavulanate potassium for oral suspension or to other beta-lactams (e.g., penicillins or cephalosporins). ( 4.1 ) • History of cholestatic jaundice/hepatic dysfunction associated with amoxicillin and clavulanate potassium for oral suspension. ( 4.2 )
4.1Serious Hypersensitivity Reactions Amoxicillin and clavulanate potassium for oral suspension are contraindicated in patients with a history of serious hypersensitivity reactions (e.g., anaphylaxis or Stevens-Johnson syndrome) to amoxicillin, clavulanate or to other beta-lactam antibacterial drugs (e.g., penicillins and cephalosporins).
4.2Cholestatic Jaundice/Hepatic Dysfunction Amoxicillin and clavulanate potassium for oral suspension is contraindicated in patients with a previous history of cholestatic jaundice/hepatic dysfunction associated with treatment with amoxicillin/clavulanate potassium.
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Serious (including fatal) hypersensitivity reactions: Discontinue amoxicillin and clavulanate potassium for oral suspension if a reaction occurs. ( 5.1 ) • Hepatic dysfunction and cholestatic jaundice: Discontinue if signs/symptoms of hepatitis occur. Monitor liver function tests in patients with hepatic impairment.
( 5.2 ) • Clostridium difficile -associated diarrhea (CDAD): Evaluate patients if diarrhea occurs. ( 5.3 ) • Patients with mononucleosis who receive amoxicillin and clavulanate potassium for oral suspension develop skin rash. Avoid amoxicillin and clavulanate potassium for oral suspension use in these patients.( 5.4 )
5.1Serious Allergic Reactions, Including Anaphylaxis Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving 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, discontinue amoxicillin and clavulanate potassium for oral suspension and institute appropriate therapy.
5.2Hepatic Dysfunction Use amoxicillin and clavulanate potassium for oral suspension with caution in patients with evidence of hepatic dysfunction. Hepatic toxicity associated with the use of amoxicillin/clavulanate potassium is usually reversible. Deaths have been reported (fewer than one death reported per estimated four million prescriptions worldwide).
These have generally been cases associated with serious underlying diseases or concomitant medications [see Contraindications (4.2) and Adverse Reactions (6.2) ].
5.3Clostridium difficile -Associated Diarrhea Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including amoxicillin and clavulanate potassium for oral suspension, 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.
5.4Skin Rash in Patients with Mononucleosis A high percentage of patients with mononucleosis who receive amoxicillin develop an erythematous skin rash. Thus, amoxicillin and clavulanate potassium for oral suspension should not be administered to patients with mononucleosis.
5.5Potential for Microbial Overgrowth The possibility of superinfections with mycotic or bacterial pathogens should be kept in mind during therapy. If superinfections occur (usually involving Pseudomonas spp . or Candida spp .), the drug should be discontinued and/or appropriate therapy instituted.
5.6Phenylketonurics Amoxicillin and clavulanate potassium for oral suspension contains aspartame which contains phenylalanine. Each 5 mL of the 600 mg/42.9 mg per 5 mL suspension of amoxicillin and clavulanate potassium powder for oral suspension contains 7.02 mg phenylalanine…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most frequently reported adverse reactions were diaper rash (4%), diarrhea (3%), vomiting (2%), candidiasis (1%), and rash (1%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Northstar Rx LLC at 1-800-206-7821 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. Two clinical trials evaluated the safety of a 10 day treatment course of amoxicillin and clavulanate potassium for oral suspension 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 (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 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 (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 and one patient in the group treated with amoxicillin and clavulanate potassium were withdrawn due to diarrhea.
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 products, including 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.
Gastrointestinal : Nausea, indigestion, gastritis, stomatitis, glossitis, black “hairy” tongue, mucocutaneous candidiasis, enterocolitis, and hemorrhagic/pseudo membranous colitis. Onset of pseudomembranous colitis symptoms may occur during or after antibacterial drug treatment. Hypersensitivity Reactions : Skin rashes, pruritus, urticaria, angioedema, serum sickness-like reactions (urticaria or skin rash accompanied by arthritis, arthralgia, myalgia, and frequently fever), erythema multiforme, Stevens-Johnson syndrome, acute generalized exanthematous pustulosis, hypersensitivity vasculitis, and an occasional case of exfoliative dermatitis (including toxic epidermal necrolysis) have been reported [see Warnings and Precautions (5.1) ].
Liver : A moderate rise in AST (SGOT) and/or ALT (SGPT) has been noted in patients treated with ampicillin-c…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Co-administration with probenecid is not recommended. ( 7.1 ) • Concomitant use of amoxicillin and clavulanate potassium for oral suspension with 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. Concurrent use with amoxicillin and clavulanate potassium for oral suspension may result in increased and prolonged blood levels of amoxicillin. Co-administration of probenecid is not recommended.
7.2Oral Anticoagulants Abnormal prolongation of prothrombin time (increased international normalized ratio [INRI]) has been reported in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken when anticoagulants are prescribed concurrently. 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 substantially 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. There are no data with amoxicillin and clavulanate potassium for oral suspension and allopurinol administered concurrently.
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 3 months to 12 years old: Modify dose according to weight. ( 2.1 , 8.4 ) Adults and pediatric patients weighing more than 40 kg: The safety and effectiveness of amoxicillin and clavulanate potassium for oral suspension has not been established. ( 8 )
8.1Pregnancy Pregnancy Category B. There are no adequate and well-controlled studies of amoxicillin and clavulanate potassium in pregnant women. Because animal reproduction studies are not always predictive of human response, use this drug during pregnancy only if clearly needed.
Reproduction studies performed in pregnant rats and mice given amoxicillin and clavulanate potassium (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. The amoxicillin doses in rodents (based on body surface area and assuming a 20 kg child) were approximately 2 times (rats) or equal to (mice) the recommended clinical amoxicillin and clavulanate potassium for oral suspension dose of 90/6.4 mg/kg/day.
For clavulanate, these dose multiples were approximately 15 times and 7.5 times the recommended daily dose of amoxicillin and clavulanate potassium for oral suspension.
8.2Labor and Delivery Oral ampicillin-class antibacterial drugs are generally poorly absorbed during labor. Studies in guinea pigs have shown that intravenous administration of ampicillin decreased the uterine tone, frequency of contractions, height of contractions, and duration of contractions. However, it is not known whether the 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 that forceps delivery or other obstetrical intervention or resuscitation of the newborn will be necessary.
In a single study in women with premature rupture of fetal membranes, it was reported that prophylactic treatment with amoxicillin and clavulanate potassium may be associated with an increased risk of necrotizing enterocolitis in neonates.
8.3Nursing Mothers Ampicillin-class antibacterial drugs are excreted in human milk; therefore, caution should be exercised when amoxicillin and clavulanate potassium is administered to a nursing woman.
8.4Pediatric Use Safety and efficacy of amoxicillin and clavulanate potassium for oral suspension in infants younger than 3 months have not been established. Safety and efficacy of amoxicillin and clavulanate potassium for oral suspension have been demonstrated for treatment of acute otitis media in infants and children 3 months to 12 years [see Description of Clinical Studies (14) ]. The safety and effectiveness of amoxicillin and clavulanate potassium for oral suspension have been established for the treatment of pediatric patients (3 months to 12 years) with acute bacterial sinusitis.
This use is supported by evidence from adequate and well-controlled studies of amoxicillin and clavulanate potassium extended-release tablets in adults with acute bacterial sinusitis, studies of amoxicillin and clavulanate potassium for oral suspension in pediatric patients with acute otitis media, and by similar pharmacokinetics of amoxicillin and clavulanate in pediatric patients taking amoxicillin and clavulanate potassium for oral suspension [see CLINICAL PHARMACOLOGY (12) ] and adults taking amoxicillin and clavulanate potassium extended-release tablets.
🤰 Pregnancy ▾

For clavulanate, these dose multiples were approximately 15 times and 7.5 times the recommended daily dose of amoxicillin and clavulanate potassium for oral suspension.
🧒 Pediatric Use ▾
8.4Pediatric Use Safety and efficacy of amoxicillin and clavulanate potassium for oral suspension in infants younger than 3 months have not been established. Safety and efficacy of amoxicillin and clavulanate potassium for oral suspension have been demonstrated for treatment of acute otitis media in infants and children 3 months to 12 years [see Description of Clinical Studies (14) ]. The safety and effectiveness of amoxicillin and clavulanate potassium for oral suspension have been established for the treatment of pediatric patients (3 months to 12 years) with acute bacterial sinusitis.
This use is supported by evidence from adequate and well-controlled studies of amoxicillin and clavulanate potassium extended-release tablets in adults with acute bacterial sinusitis, studies of amoxicillin and clavulanate potassium for oral suspension in pediatric patients with acute otitis media, and by similar pharmacokinetics of amoxicillin and clavulanate in pediatric patients taking amoxicillin and clavulanate potassium for oral suspension [see CLINICAL PHARMACOLOGY (12) ] and adults taking amoxicillin and clavulanate potassium extended-release tablets.
🆘 Overdosage ▾
10 OVERDOSAGE Following overdosage, patients have experienced primarily gastrointestinal symptoms including stomach and abdominal pain, vomiting, and diarrhea. Rash, hyperactivity, or drowsiness has also been observed in a small number of patients. In the case of overdosage, discontinue amoxicillin and clavulanate potassium for oral suspension, treat symptomatically, and institute supportive measures as required.
If the overdosage is very recent and there is no contraindication, an attempt at emesis or other means of removal of drug from the stomach may be performed. A prospective study of 51 pediatric patients at a poison control center suggested that overdosage of less than 250 mg/kg of amoxicillin is not associated with significant clinical symptoms and does not require gastric emptying 1 . Interstitial nephritis resulting in oliguric renal failure has been reported in a small number of patients after overdosage with amoxicillin.
Crystalluria, in some cases leading to renal failure, has also been reported after amoxicillin overdosage in adult and pediatric patients. In case of overdosage, adequate fluid intake and diuresis should be maintained to reduce the risk of amoxicillin 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 both amoxicillin and clavulanate. Both amoxicillin and clavulanate are removed from the circulation by hemodialysis.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Amoxicillin and clavulanate potassium for oral suspension is an antibacterial drug [see Microbiology (12.4 ) ].
12.3Pharmacokinetics The pharmacokinetics of amoxicillin and clavulanate were determined in a study of 19 pediatric patients, 8 months to 11 years, given amoxicillin and clavulanate potassium for oral suspension at an amoxicillin dose of 45 mg/kg q12h with a snack or meal. The mean plasma amoxicillin and clavulanate pharmacokinetic parameter values are listed in the following table. Table 1.
Mean (±SD) Plasma Amoxicillin and Clavulanate Pharmacokinetic Parameter Values Following Administration of 45 mg/kg of Amoxicillin and Clavulanate Potassium for Oral Suspension Every 12 Hours to Pediatric Patients PARAMETER AMOXICILLIN CLAVULANATE C max (mcg/mL) 15.7 ± 7.7 1.7 ±

1.9T½(hour) 1.4 ± 0.3 1.1 ±
0.3CL/F (L/hour/kg) 0.9 ± 0.4 1.1 ± 1.1 * Arithmetic mean ± standard deviation, except T max values which are medians (ranges). The effect of food on the oral absorption of amoxicillin and clavulanate potassium for oral suspension has not been studied. Approximately 50% to 70% of the amoxicillin and approximately 25% to 40% of the clavulanic acid are excreted unchanged in urine during the first 6 hours after administration of 10 mL of 250 mg/5 mL suspension of amoxicillin and clavulanate potassium.
Concurrent administration of probenecid delays amoxicillin excretion but does not delay renal excretion of clavulanic acid. Neither component in amoxicillin and clavulanate potassium for oral suspension is highly protein-bound; clavulanic acid has been found to be approximately 25% bound to human serum and amoxicillin approximately 18% bound. Oral administration of a single dose of amoxicillin and clavulanate potassium for oral suspension at 45 mg/kg (based on the amoxicillin component) to pediatric patients, 9 months to 8 years, yielded the following pharmacokinetic data for amoxicillin in plasma and middle ear fluid (MEF): Table 2.

Amoxicillin diffuses readily into most body tissues and fluids with the exception of the brain and spinal fluid. The results of experiments involving the administration of clavulanic acid to animals suggest that this compound, like amoxicillin, is well distributed in body tissues.
12.4Microbiology Mechanism of Action Amoxicillin binds to penicillin-binding proteins within the bacterial cell wall and inhibits bacterial cell wall synthesis. Clavulanic acid is a beta-lactam, structurally related to penicillin, that may inactivate certain beta-lactamase enzymes. Mechanism of Resistance Resistance to penicillins may be mediated by destruction of the beta-lactam ring by a beta-lactamase, altered affinity of penicillin for target, or decreased penetration of the antimicrobial drug to reach the target site.
Amoxicillin alone is susceptible to degradation by beta-lactamases, and therefore its spectrum of activity does not include bacteria that produce these enzymes. Amoxicillin/clavulanic acid has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section (1). Gram-positive bacteria: Streptococcus pneumoniae (including isolates with penicillin MICs ≤ 2 mcg/mL) Gram-negative bacteria: Haemophilus influenzae (including beta-lactamase-producing iso…

📋 Description ▾
11 DESCRIPTION Amoxicillin and clavulanate potassium for oral suspension, USP is an oral antibacterial combination consisting of the semisynthetic antibacterial amoxicillin and the beta-lactamase inhibitor, clavulanate potassium (the potassium salt of clavulanic acid). Amoxicillin 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 0 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 a wide variety of beta - lactamases by blocking the active sites of these enzymes. Clavulanic acid is particularly active against the clinically important plasmid-mediated beta-lactamases frequently responsible for transferred drug resistance to penicillins and cephalosporins.
The clavulanate potassium molecular formula is C 8 H 8 KN0 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: Amoxicillin and clavulanate potassium for oral suspension, USP is white to off-white granular powder and becomes white to pale yellow suspension with strawberry flavor after reconstitution. Inactive Ingredients: —Aspartame*, colloidal silicon dioxide, hypromellose, silicon dioxide, strawberry cream permaseal, succinic acid, and xanthan gum [see Warnings and Precautions (5.6) ].
Each 5 mL of reconstituted amoxicillin and clavulanate potassium for oral suspension USP, 600 mg/42.9 mg per 5 mL contains 600 mg amoxicillin as the trihydrate and 42.9 mg clavulanic acid as the potassium salt (clavulanate potassium). The potassium content per 5 mL is 0.21 mEq. Amoxicillin chemical structure clavulanate potassium chemical structure
💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Take amoxicillin and clavulanate potassium for oral suspension every 12 hours with a meal or snack to reduce the possibility of gastrointestinal upset. If diarrhea develops and is severe or lasts more than 2 or 3 days, call your doctor. Counsel patients that antibacterial drugs, including amoxicillin and clavulanate potassium for oral suspension, should only be used to treat bacterial infections.
Antibacterial drugs 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, tell patients 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.
Counsel patients that diarrhea is a common problem caused by antibacterial drugs which usually ends when the antibacterial drug is discontinued. Sometimes after starting treatment with antibacterial drugs, patient can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken the last dose of the antibacterial drug. If this occurs, patients should contact their physician as soon as possible.
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 dosing spoon or medicine dropper.
Be sure to rinse the spoon or dropper 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.
Discard any unused medicine. Counsel patients that amoxicillin and clavulanate potassium for oral suspension contains a penicillin class drug product that can cause allergic reactions in some individuals. Counsel patients with phenylketonuria: Each 5 mL of the 600 mg/42.9 mg per 5 mL suspension of amoxicillin and clavulanate potassium for oral suspension contains 7.02 mg phenylalanine.
