Patients treated with amoxicillin should have a follow-up serologic test for syphilis after 3 months. Probenecid decreases the renal tubular secretion of amoxicillin. Concurrent use of amoxicillin and probenecid may result in increased and prolonged blood levels of amoxicillin. 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. Following administration of ampicillin to pregnant women, a transient decrease in plasma concentration of total conjugated estriol, estriol-glucuronide, conjugated estrone, and estradiol has been noted.

This effect may also occur with amoxicillin. Carcinogenesis, Mutagenesis, Impairment of Fertility: Long-term studies in animals have not been performed to evaluate carcinogenic potential. Studies to detect mutagenic potential of amoxicillin alone have not been conducted; however, the following information is available from tests on a 4: AUGMENTIN was weakly positive in the mouse lymphoma assay, but the trend toward increased mutation frequencies in this assay occurred at doses that were also associated with decreased cell survival.

Potassium clavulanate alone was tested in the Ames bacterial mutation assay and in the mouse micronucleus test, and was negative in each of these assays. Reproduction studies have been performed in mice and rats at doses up to 10 times the human dose and have revealed no evidence of impaired fertility or 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, this drug should be used during pregnancy only if clearly needed. Oral ampicillin-class antibiotics are poorly absorbed during labor. Studies in guinea pigs showed that intravenous administration of ampicillin slightly decreased the uterine tone and frequency of contractions but moderately increased the height and duration of contractions.

However, 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 that forceps delivery or other obstetrical intervention or resuscitation of the newborn will be necessary. 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. Because of incompletely developed renal function in neonates and young infants, the elimination of amoxicillin may be delayed. An analysis of clinical studies of amoxicillin was conducted to determine whether subjects aged 65 and over respond differently from younger subjects.

This analysis and other reported clinical experience 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 may be useful to the monitor renal function.

Amoxicillin may be taken every 8 hours or every 12 hours, depending on the strength of the product 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. 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: They are more likely to occur in individuals who have previously demonstrated hypersensitivity to penicillins and in those with a history of allergy, asthma, hay fever, or urticaria. The following adverse reactions have been reported as associated with the use of penicillins: Onset of pseudomembranous colitis symptoms may occur during or after antibiotic treatment.

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. These hypersensitivity reactions may be controlled with antihistamines and, if necessary, systemic corticosteroids. Whenever such reactions occur, amoxicillin should be discontinued unless, in the opinion of the physician, the condition being treated is life-threatening and amenable only to amoxicillin therapy.

Hepatic dysfunction including cholestatic jaundice, hepatic cholestasis and acute cytolytic hepatitis have been reported. 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. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. Development Of Drug-Resistant Bacteria Prescribing AMOXIL 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 Use 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. Phenylketonurics Amoxil chewable tablets contain aspartame which contains phenylalanine.

Each mg chewable tablet contains 1. The oral suspensions of Amoxil do not contain phenylalanine and can be used by phenylketonurics. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Long-term studies in animals have not been performed to evaluate carcinogenic potential. Studies to detect mutagenic potential of amoxicillin alone have not been conducted; however, the following information is available from tests on a 4: AUGMENTIN was weakly positive in the mouse lymphoma assay, but the trend toward increased mutation frequencies in this assay occurred at doses that were also associated with decreased cell survival.

Potassium clavulanate alone was tested in the Ames bacterial mutation assay and in the mouse micronucleus test, and was negative in each of these assays. 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.

Labor 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. Nursing 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. Pediatric Use Because of incompletely developed renal function in neonates and young infants, the elimination of amoxicillin may be delayed. 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. See Dosing in Renal Impairment for specific recommendations in patients with renal impairment.

Interstitial nephritis resulting in oliguric renal failure has been reported in a small number of patients after overdosage with amoxicillin1.

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.

Amoxicillin to detect mutagenic potential of amoxicillin alone have not been conducted; however, the following information is available from tests on a 4: They do not treat viral infections e. Infections of the skin and skin structure — due to Streptococcus spp. Oral Anticoagulants Abnormal prolongation of prothrombin time increased international 500 ratio [INR] has been reported in patients receiving amoxicillin and oral anticoagulants. West-ward of the genitourinary tract — due to E. Other Antibacterials Chloramphenicol, macrolides, sulfonamidesand tetracyclines may interfere with the 500 effects of penicillin. Although anaphylaxis is more frequent following parenteral therapy, it has occurred in patients on oral penicillins. Because of incompletely developed renal function in neonates and young infants, the elimination of amoxicillin may be delayed. This effect may also occur with amoxicillin. Caution should be exercised when amoxicillin is administered to amoxicillin nursing woman.
