🩺 Clinical
Amoxicillin is used to treat certain infections caused by bacteria, such as pneumonia, skin, and urinary tract infections eliminate H. pylori, a bacteria that causes ulcers in combination with other medications Amoxicillin is in a class of medications called penicillin-like antibiotics. It works by stopping the growth of bacteria. Antibiotics such as amoxicillin will not work for colds, flu, and other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE To reduce the development of drug-resistant bacteria and maintain the effectiveness of amoxicillin and other antibacterial drugs, amoxicillin should be used only to treat infections that are proven or strongly suspected to be caused by 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 is indicated in the treatment of infections due to susceptible (ONLY β-lactamase–negative) isolates of the designated bacteria in the conditions listed below: Amoxicillin is a penicillin-class antibacterial indicated for treatment of infections due to susceptible strains of designated microorganisms. • Infections of the ear, nose, throat, genitourinary tract, skin and skin structure, and lower respiratory tract. ( 1.1 to 1.5 ) • In combination for treatment of H. pylori infection and duodenal ulcer disease.
( 1.6 , 1.7 )
1.1Infections of the Ear, Nose, and Throat – due to Streptococcus species. (α- and β-hemolytic isolates only), Streptococcus pneumoniae , Staphylococcus spp., or Haemophilus influenzae .
1.2Infections of the Genitourinary Tract – due to Escherichia coli, Proteus mirabilis , or Enterococcus faecalis .
1.3Infections of the Skin and Skin Structure – due to Streptococcus spp. (α- and β-hemolytic isolates only), Staphylococcus spp., or E. coli .
1.4Infections of the Lower Respiratory Tract – due to Streptococcus spp. (α- and β-hemolytic isolates only), S. pneumoniae, Staphylococcus spp., or H. influenzae .
1.5Gonorrhea, Acute Uncomplicated (Ano-Genital and Urethral Infections in Males and Females) – due to Neisseria gonorrhoeae . Because of high rates of amoxicillin resistance, amoxicillin is not recommended for empiric treatment of gonorrhea. Amoxicillin use should be limited to situations where N. gonorrhoeae isolates are known to be susceptible to amoxicillin.
1.6Triple Therapy for Helicobacter pylori With Clarithromycin and Lansoprazole Amoxicillin, in combination with clarithromycin plus lansoprazole as triple therapy, is indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease (active or 1 year history of a duodenal ulcer) to eradicate H. pylori . Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence.
1.7Dual Therapy for H. pylori With Lansoprazole Amoxicillin, in combination with lansoprazole delayed-release capsules as dual therapy, is indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease (active or 1 year history of a duodenal ulcer) who are either allergic or intolerant to clarithromycin or in whom resistance to clarithromycin is known or suspected . (See the clarithromycin package insert, MICROBIOLOGY.) Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION • In adults, 750 to 1750 mg/day in divided doses every 8 to 12 hours. In Pediatric Patients > 3 Months of Age, 20 to 45 mg/kg/day in divided doses every 8 to 12 hours. Refer to full prescribing information for specific dosing regimens.
( 2.1 , 2.2 , 2.3 ) • Treatment of gonorrhea is 3 grams as a single oral dose. ( 2.1 ) • The upper dose for neonates and infants ≤ 3 months is 30 mg/kg/day divided every 12 hours. ( 2.2 ) • Dosing for H. pylori Infection: Triple therapy: 1 gram amoxicillin, 500 mg clarithromycin, and 30 mg lansoprazole, all given twice daily (every 12 hours) for 14 days.
Dual therapy: 1 gram amoxicillin and 30 mg lansoprazole, each given three times daily (every 8 hours) for 14 days. ( 2.3 ) • Reduce the dose in patients with severe renal impairment (GFR < 30 mL/min). ( 2.4 )
2.1Dosing for Adult and Pediatric Patients > 3 Months of Age Except for gonorrhea, treatment should be continued for a minimum of 48 to 72 hours beyond the time that the patient becomes asymptomatic or evidence of bacterial eradication has been obtained. It is recommended that there be at least 10 days’ treatment for any infection caused by Streptococcus pyogenes to prevent the occurrence of acute rheumatic fever. In some infections, therapy may be required for several weeks.
It may be necessary to continue clinical and/or bacteriological follow-up for several months after cessation of therapy. Table 1. Dosing Recommendations for Adult and Pediatric Patients > 3 Months of Age Infection Severity Dosing for infections caused by bacteria that are intermediate in their susceptibility to amoxicillin should follow the recommendations for severe infections.
Usual Adult Dose Usual Dose for Children > 3 Months The children’s dosage is intended for individuals whose weight is less than 40 kg. Children weighing 40 kg or more should be dosed according to the adult recommendations. Ear/Nose/Throat Skin/Skin Structure Genitourinary Tract Mild/Moderate 500 mg every 12 hours or 250 mg every 8 hours 25 mg/kg/day in divided doses every 12 hours or 20 mg/kg/day in divided doses every 8 hours Severe 875 mg every 12 hours or 500 mg every 8 hours 45 mg/kg/day in divided doses every 12 hours or 40 mg/kg/day in divided doses every 8 hours Lower Respiratory Tract Mild/Moderate or Severe 875 mg every 12 hours or 500 mg every 8 hours 45 mg/kg/day in divided doses every 12 hours or 40 mg/kg/day in divided doses every 8 hours Gonorrhea Acute, Uncomplicated Ano-Genital and Urethral Infections in Males and Females 3 grams as single oral dose Prepubertal children: 50 mg/kg amoxicillin, combined with 25 mg/kg probenecid as a single dose.
Note: since probenecid is contraindicated in children under 2 years, do not use this regimen in children under 2 years of age.
2.2Dosing in Neonates and Infants Aged ≤ 12 Weeks (≤ 3 Months) Treatment should be continued for a minimum of 48 to 72 hours beyond the time that the patient becomes asymptomatic or evidence of bacterial eradication has been obtained. It is recommended that there be at least 10 days’ treatment for any infection caused by Streptococcus pyogenes to prevent the occurrence of acute rheumatic fever. Due to incompletely developed renal function affecting elimination of amoxicillin in this age group, the recommended upper dose of amoxicillin is 30 mg/kg/day divided every 12 hours.
There are currently no dosing recommendations for pediatric patients with impaired renal function.
2.3Dosing for H. pylori Infection Triple Therapy: The recommended adult oral dose is 1 gram amoxicillin, 500 mg clarithromycin, and 30 mg lansoprazole, all given twice daily (every 12 hours) for 14 days. Dual Therapy: The recommended adult oral dose is 1 gram amoxicillin and 30 mg lansoprazole, each given three times daily (every 8 hours) for 14 days. Please refer to clarithromycin and lansoprazole full prescribing information.

⛔ Contraindications ▾
4 CONTRAINDICATIONS Amoxicillin is contraindicated in patients who have experienced a serious hypersensitivity reaction (e.g., anaphylaxis or Stevens-Johnson syndrome) to amoxicillin or to other β-lactam antibiotics (e.g., penicillins and cephalosporins). • History of a serious hypersensitivity reaction (e.g., anaphylaxis or Stevens-Johnson syndrome) to amoxicillin or to other beta-lactams (e.g., penicillins or cephalosporins) ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Anaphylactic Reactions: Serious and occasionally fatal anaphylactic reactions have been reported in patients on penicillin therapy. Serious anaphylactic reactions require immediate emergency treatment with supportive measures. ( 5.1 ) • Clostridium difficile Associated Diarrhea (ranging from mild diarrhea to fatal colitis): Evaluate if diarrhea occurs. ( 5.2 )
5.1Anaphylactic Reactions Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients on penicillin therapy including amoxicillin. Although anaphylaxis is more frequent following parenteral therapy, it has occurred in patients on oral penicillins. These reactions are more likely to occur in individuals with a history of penicillin hypersensitivity and/or a history of sensitivity 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 initiating therapy with amoxicillin, careful inquiry should be made regarding previous hypersensitivity reactions to penicillins, cephalosporins, or other allergens.
5.2Clostridium difficile Associated Diarrhea Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including amoxicillin, 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 use. Careful medical history is necessary since CDAD has been reported to occur over 2 months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated.
5.3Potential for Microbial Overgrowth or Bacterial Resistance The possibility of superinfections with fungal or bacterial pathogens should be considered during therapy. If superinfections occur, amoxicillin should be discontinued and appropriate therapy instituted. Prescribing amoxicillin either in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient, and increases the risk of the development of drug-resistant bacteria.
5.4Use in Patients With Mononucleosis A high percentage of patients with mononucleosis who receive amoxicillin develop an erythematous skin rash. Thus amoxicillin should not be administered to patients with mononucleosis.
🤒 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 ) ] • CDAD [ see Warnings and Precautions ( 5.2 ) ] The most common adverse reactions (> 1%) observed in clinical trials of amoxicillin capsules, tablets (chewable) or oral suspension were diarrhea, rash, vomiting, and nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact TEVA USA, PHARMACOVIGILANCE at 1-866-832-8537 or [email protected]; or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical 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. The most common adverse reactions (> 1%) observed in clinical trials of amoxicillin capsules, tablets or oral suspension were diarrhea, rash, vomiting, and nausea. Triple Therapy: The most frequently reported adverse events for patients who received triple therapy (amoxicillin/clarithromycin/lansoprazole) were diarrhea (7%), headache (6%), and taste perversion (5%).
Dual Therapy: The most frequently reported adverse events for patients who received double therapy amoxicillin/lansoprazole were diarrhea (8%) and headache (7%). For more information on adverse reactions with clarithromycin or lansoprazole, refer to the Adverse Reactions section of their package inserts.
6.2Postmarketing or Other Experience In addition to adverse events reported from clinical trials, the following events have been identified during postmarketing use of penicillins. 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. • Infections and Infestations: Mucocutaneous candidiasis. • Gastrointestinal: Black hairy tongue and hemorrhagic/pseudomembranous colitis.
Onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment [ see Warnings and Precautions ( 5.2 ) ]. • Hypersensitivity Reactions: Anaphylaxis [ see Warnings and Precautions ( 5.1 ) ]. Serum sickness–like reactions, erythematous maculopapular rashes, erythema multiforme, Stevens-Johnson syndrome, exfoliative dermatitis, toxic epidermal necrolysis, acute generalized exanthematous pustulosis, hypersensitivity vasculitis, and urticaria have been reported. • Liver: A moderate rise in AST and/or ALT has been noted, but the significance of this finding is unknown.
Hepatic dysfunction including cholestatic jaundice, hepatic cholestasis and acute cytolytic hepatitis have been reported. • Renal: Crystalluria has been reported [ see Overdosage ( 10 ) ]. • Hemic and Lymphatic Systems: Anemia, including hemolytic anemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia, and agranulocytosis have been reported. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. • Central Nervous System: Reversible hyperactivity, agitation, anxiety, insomnia, confusion, convulsions, behavioral changes, and/or dizziness 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.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Probenicid decreases renal tubular secretion of amoxicillin which may result in increased blood levels of amoxicillin. ( 7.1 ) • Concomitant use of amoxicillin and oral anticoagulants may increase the prolongation of prothrombin time. ( 7.2 ) • Coadministration with allopurinol increases the risk of rash. ( 7.3 ) • Amoxicillin may reduce the efficacy of oral contraceptives. ( 7.4 )
7.1Probenecid Probenecid decreases the renal tubular secretion of amoxicillin. Concurrent use of amoxicillin and probenecid may result in increased and prolonged blood levels of amoxicillin.
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. 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 may affect the gut flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives.
7.5Other Antibacterials Chloramphenicol, macrolides, sulfonamides, and tetracyclines may interfere with the bactericidal effects of penicillin. This has been demonstrated in vitro ; however, the clinical significance of this interaction is not well documented.
7.6Drug/Laboratory Interactions High urine concentrations of ampicillin 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, it is recommended that glucose tests based on enzymatic glucose oxidase reactions (such as CLINISTIX ® ) be used. Following administration of ampicillin or 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: Modify dose in patients 12 weeks or younger (≤ 3 months). ( 8.4 )
8.1Pregnancy Teratogenic Effects Pregnancy Category B Reproduction studies have been performed in mice and rats at doses up to 2000 mg/kg (3 and 6 times the 3 g human dose, based on body surface area). There was no evidence of harm to the fetus due to amoxicillin. There are, however, no adequate and well-controlled studies in pregnant women.
Because animal reproduction studies are not always predictive of human response, amoxicillin should be used during pregnancy only if clearly needed.
8.2Labor and Delivery Oral ampicillin is poorly absorbed during labor. It is not known whether use of amoxicillin 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 Penicillins have been shown to be excreted in human milk. Amoxicillin use by nursing mothers may lead to sensitization of infants. Caution should be exercised when amoxicillin is administered to a nursing woman.
8.4Pediatric Use Because of incompletely developed renal function in neonates and young infants, the elimination of amoxicillin may be delayed. Dosing of amoxicillin should be modified in pediatric patients 12 weeks or younger (≤ 3 months) [ see Dosage and Administration ( 2.2 ) ].
8.5Geriatric Use An analysis of clinical studies of amoxicillin was conducted to determine whether subjects aged 65 and over respond differently from younger subjects. These analyses have not identified differences in responses between the elderly and younger patients, but a 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 toxic 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.
8.6Dosing in Renal Impairment Amoxicillin is primarily eliminated by the kidney and dosage adjustment is usually required in patients with severe renal impairment (GFR < 30 mL/min). See Dosing in Renal Impairment ( 2.4 ) for specific recommendations in patients with renal impairment.

🆘 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. Interstitial nephritis resulting in oliguric renal failure has been reported in a small number of patients after overdosage with amoxicillin 1 .
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 amoxicillin. Amoxicillin may be removed from circulation by hemodialysis.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Amoxicillin is an antibacterial drug [ see Microbiology ( 12.4 ) ].
12.3Pharmacokinetics Absorption Amoxicillin is stable in the presence of gastric acid and is rapidly absorbed after oral administration. The effect of food on the absorption of amoxicillin from the tablets and suspension of amoxicillin has been partially investigated; 400 mg and 875 mg formulations have been studied only when administered at the start of a light meal. Orally administered doses of 250 mg and 500 mg amoxicillin capsules result in average peak blood levels 1 to 2 hours after administration in the range of 3.5 mcg/mL to 5 mcg/mL and 5.5 mcg/mL to 7.5 mcg/mL, respectively.
Mean amoxicillin pharmacokinetic parameters from an open, two-part, single-dose crossover bioequivalence study in 27 adults comparing 875 mg of amoxicillin with 875 mg of amoxicillin/clavulanate potassium showed that the 875 mg of amoxicillin tablet produces an AUC 0 to ∞ of 35.4 ± 8.1 mcg•hr/mL and a C max of 13.8 ± 4.1 mcg/mL. Dosing was at the start of a light meal following an overnight fast. Orally administered doses of amoxicillin suspension, 125 mg/5 mL and 250 mg/5 mL, result in average peak blood levels 1 to 2 hours after administration in the range of 1.5 mcg/mL to 3 mcg/mL and 3.5 mcg/mL to 5 mcg/mL, respectively.
Oral administration of single doses of 400 mg chewable tablets and 400 mg/5 mL suspension of amoxicillin to 24 adult volunteers yielded comparable pharmacokinetic data: Table 3: Mean Pharmacokinetic Parameters of Amoxicillin (400 mg chewable tablets and 400 mg/5 mL suspension) in Healthy Adults Dose Administered at the start of a light meal.

Amoxicillin (± S.D.) 400 mg (5 mL of suspension) 17.1 (3.1) 5.92 (1.62) 400 mg (1 chewable tablet) 17.9 (2.4) 5.18 (1.64) Distribution Amoxicillin diffuses readily into most body tissues and fluids, with the exception of brain and spinal fluid, except when meninges are inflamed. In blood serum, amoxicillin is approximately 20% protein-bound. Following a 1 gram dose and utilizing a special skin window technique to determine levels of the antibiotic, it was noted that therapeutic levels were found in the interstitial fluid.
Metabolism and Excretion The half-life of amoxicillin is 61.3 minutes. Approximately 60% of an orally administered dose of amoxicillin is excreted in the urine within 6 to 8 hours. Detectable serum levels are observed up to 8 hours after an orally administered dose of amoxicillin.
Since most of the amoxicillin is excreted unchanged in the urine, its excretion can be delayed by concurrent administration of probenecid [ see DRUG INTERACTIONS ( 7.1 ) ].
12.4Microbiology Mechanism of Action Amoxicillin is similar to penicillin in its bactericidal action against susceptible bacteria during the stage of active multiplication. It acts through the inhibition of cell wall biosynthesis that leads to the death of the bacteria. Method of Resistance Resistance to amoxicillin is mediated primarily through enzymes called beta-lactamases that cleave the beta-lactam ring of amoxicillin, rendering it inactive.
Amoxicillin has been shown to be active against most isolates of the bacteria listed below, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section. Gram-Positive Bacteria Gram-Negative Bacteria Enterococcus faecalis Escherichia coli Staphylococcus spp. Haemophilus influenzae Streptococcus pneumoniae Neisseria gonorrhoeae Alpha and β-hemolytic streptococci.

17 PATIENT COUNSELING INFORMATION
17.1Information for Patients • Patients should be advised that amoxicillin may be taken every 8 hours or every 12 hours, depending on the dose prescribed. • Patients should be counseled that antibacterial drugs, including amoxicillin, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When amoxicillin 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 or other antibacterial drugs in the future. • Patients should be counseled that diarrhea is a common problem caused by antibiotics, and it usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, 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 antibiotic.
If this occurs, patients should contact their physician as soon as possible. • Patients should be aware that amoxicillin contains a penicillin class drug product that can cause allergic reactions in some individuals.
