4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Amoxicillin is a broad spectrum antibiotic indicated for the treatment of commonly occurring bacterial infections including upper respiratory infections, acute and chronic bronchitis, chronic bronchial sepsis, pneumonia, ear, nose and throat infections, otitis media, urinary tract infection, cystitis, urethritis, pyelonephritis, gonorrhoea, invasive salmonellosis, bacteriuria in pregnancy, gynaecological infections including puerperal sepsis and septic abortion, peritonitis, intra-abdominal sepsis, septicaemia, osteomyelitis, meningitis, bacterial endocarditis, typhoid and paratyphoid fever, skin and soft tissue infections, dental abscess (as an adjunct to surgical management)
In children with urinary tract infection, the need for further clinical investigation should be considered.
Prophylaxis of endocarditis: Amoxicillin may be used for the prevention of bacteraemia, associated with procedures such as dental extraction, in patients at risk of developing bacterial endocarditis.
Consideration should be given to official local guidance (e.g. national requirements) on the appropriate use of antibacterial agents. Susceptibility of the causative organism to the treatment should be tested (if possible), although the therapy may be initiated before the results are available.
4.2 Posology and method of administration
Treatment of infection
Adult dosage (including elderly patients):
Standard adult dosage
250 mg three times daily, increasing to 500 mg three times daily for more severe infections
High Dosage Therapy
Up to a maximum of 6g daily in divided doses. A dosage of 3 g twice daily is recommended in appropriate cases for the treatment of severe or recurrent purulent infection of the respiratory tract.
Short course therapy
Simple acute urinary tract infections
Two 3 g doses with 10-12 hours between the doses.
Dental abscess
Two 3 g doses with 8 hours between the doses.
Gonorrhoea
3 g single dose in combination with 1 g Probenecid.
Children (up to ten years of age):
125mg every eight hours which may be doubled in severe infections.
In dental prophylaxis, the same precautions apply as with adults, the normal dosage in children, 5 - 10 years is half the adult dose and quarter the adult dose in children under 5 years.
Children weighing < 40 kg
The daily dosage for children is 40 - 90 mg/kg/day in two to three divided doses* (not exceeding 3 g/day) depending on the indication, severity of the disease and the susceptibility of the pathogen (see special dosage recommendations below and sections 4.4, 5.1 and 5.2).
*PK/PD data indicate that dosing three times daily is associated with enhanced efficacy, thus twice daily dosing is only recommended when the dose is in the upper range.
Children weighing more than 40 kg should be given the usual adult dosage.
Special dosage recommendation Tonsillitis: 50 mg/kg/day in two divided doses.
Acute otitis media: In areas with high prevalence of pneumococci with reduced susceptibility to penicillins, dosage regimens should be guided by national/local recommendations. In severe or recurrent acute otitis media, especially where compliance may be a problem, 750 mg twice a day for two days may be used as an alternative course of treatment in children aged 3 to 10 years.
Early Lyme disease (isolated erythema migrans): 50 mg/kg/day in three divided doses, over 14-21days.
Dosage in impaired renal function:
The dose should be reduced in patients with severe renal function impairment. In patients with a creatinine clearance of less than 30 ml/min an increase in the dosage interval and a reduction in the total daily dose is recommended (see section 4.4 and 5.2).
Glomerular filtration rate > 30 ml/min: No adjustment necessary.
Glomerular filtration rate 10-30 ml/min: Amoxicillin max. 500 mg b.d Glomerular filtration rate < 10 ml/min: Amoxicillin max. 500 mg/day Renal impairment in children under 40 kg:

Method of administration:
Oral
Treatment should be continued for 2 to 3 days following the disappearance of symptoms. It is recommended that at least 10 days treatment be given for any infection caused by beta-haemolytic streptococci in order to achieve eradication of the organism.
4.3 Contraindications
Amoxicillin is a penicillin and should not be given to penicillin-hypersensitive patients and patients with hypersensitivity to the listed ingredients. Attention should be paid to possible cross-sensitivity with other beta-lactam antibiotics e.g. cephalosporins.
4.4 Special warnings and precautions for use
Before initiating therapy with amoxicillin, careful enquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins.
Serious and occasionally fatal hypersensitivity (anaphylactoid) reactions have been reported in patients on penicillin therapy. These reactions are more likely to occur in individuals with a history of hypersensitivity to beta-lactam antibiotics (see 4.3).
Erythematous (morbilliform) rashes have been associated with glandular fever in patients receiving amoxicillin.
Prolonged use may also occasionally result in overgrowth of non-susceptible organisms.
In patients with reduced urine output, crystalluria has been observed very rarely, predominantly with parenteral therapy. During the administration of high doses of amoxicillin, it is advisable to maintain adequate fluid intake and urinary output in order to reduce the possibility of amoxicillin crystalluria (see section 4.9 Overdose).
In patients with renal impairment, the rate of excretion of amoxicillin will be reduced depending on the degree of impairment and it may be necessary to reduce the total daily unit amoxicillin dosage accordingly.
Abnormal prolongation of prothrombin time (increased INR) has been reported rarely in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken when anticoagulants are prescribed concomitantly. Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation (see sections 4.5 and 4.8).
Precaution should be taken in premature children and during the neonatal period: renal, hepatic and haematological functions should be monitored.
4.5 Interaction with other medicinal products and other forms of interaction
Probenecid decreases the renal tubular secretion of amoxicillin. Concurrent use with Amoxicillin may result in increased and prolonged blood levels of amoxicillin.
In common with other antibiotics, amoxicillin may affect the gut flora, leading to lower oestrogen reabsorption and reduced efficacy of combined oral contraceptives.
Concurrent administration of allopurinol during treatment with amoxicillin can increase the likelihood of allergic skin reactions.
In the literature there are rare cases of increased international normalised ratio in patients maintained on acenocoumarol or warfarin and prescribed a course of amoxicillin. If co-administration is necessary, the prothrombin time or international normalised ratio should be carefully monitored with the addition or withdrawal of amoxicillin (see sections 4.4 and 4.8).
Penicillins reduce excretion of methotrexate (increased risk of toxicity).
Excretion of penicillins reduced by sulfinpyrazone.
It is recommended that when testing for the presence of glucose in urine during amoxicillin treatment, enzymatic glucose oxidase methods should be used. Due to the high urinary concentrations of amoxicillin, false positive readings are common with chemical methods.
4.6 Pregnancy and lactation
Use in Pregnancy:
Animal studies with amoxicillin have shown no teratogenic effects. The product has been in extensive clinical use since 1972 and its suitability in human pregnancy has been well documented in clinical studies. When antibiotic therapy is required during pregnancy, amoxicillin may be considered appropriate when the potential benefits outweigh the potential risks associated with treatment.
Use in Lactation:
Amoxicillin may be given during lactation. With the exception of the risk of sensitisation associated with the excretion of trace quantities of amoxicillin in breast milk, there are no known detrimental effects for the breast-fed infant.
4.7 Effects on ability to drive and use machines
Adverse effects on the ability to drive or operate machinery have not been observed.
4.8 Undesirable effects
The following convention has been utilised for the classification of undesirable effects:
Very common (>1/10), common (>1/100, <1/10), uncommon (>1/1000, <1/100), rare (>1/10,000, <1/1000), very rare (<1/10,000).
The majority of side effects listed below are not unique to amoxicillin and may occur when using other penicillins.
Unless otherwise stated, the frequency of adverse events has been derived from more than 30 years of post-marketing reports.
Infections and infestations
Very rare: Mucocutaneous candidiasis
Blood and lymphatic system disorders
Very rare: Reversible leucopenia (including severe neutropenia or agranulocytosis), reversible thrombocytopenia and haemolytic anaemia. Prolongation of bleeding time and prothrombin (see section 4.5 - Interaction with other Medicaments and other Forms of Interaction)
Immune system disorders
Very rare: As with other antibiotics, severe allergic reactions, including angioneurotic oedema, anaphylaxis (see section 4.4 - Special Warnings and Precautions for Use), serum sickness and hypersensitivity vasculitis.
If a hypersensitivity reaction is reported, the treatment must be discontinued. (See also Skin and subcutaneous tissue disorders).
Nervous system disorders
Very rare: Hyperkinesia, dizziness and convulsions. Convulsions may occur in patients with impaired renal function or in those receiving high doses.
Gastro intestinal disorders
Clinical Trial Data *Common: Diarrhoea and nausea.
*Uncommon: Vomiting.
Post-marketing Data
Very rare: Antibiotic associated colitis (including pseudomembraneous colitis and haemorrhagic colitis).
Black hairy tongue
Superficial tooth discolouration has been reported in children. Good oral hygiene may help to prevent tooth discolouration as it can usually be removed by brushing.
Hepato-biliary disorders
Very rare: Hepatitis and cholestatic jaundice. A moderate rise in AST and/or ALT. The significance of a rise in AST and/or ALT is unclear.
Skin and subcutaneous tissue disorders
Clinical Trial Data *Common: Skin rash *Uncommon: Urticaria and pruritus Post-marketing Data
Very rare: Skin reactions such as erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, bullous and exfoliative dermatitis and acute generalised exanthematous pustulosis (AGEP)
(See also Immune system disorders).
Renal and urinary tract disorders
Very rare: Interstitial nephritis.
Very rare: Crystalluria (see section 4.9 Overdose)
*The incidence of these AEs was derived from clinical studies involving a total of approximately 6,000 adult and paediatric patients taking amoxicillin.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme, Website: www.mhra.gov.uk/yellowcard
4.9 Overdose
Gastrointestinal effects such as nausea, vomiting and diarrhoea may be evident and should be treated symptomatically with attention to the water/electrolyte balance. Amoxicillin crystalluria, in some cases leading to renal failure, has been observed (see section 4.4 Special warnings and special precautions for use). Amoxicillin may be removed from the circulation by haemodialysis.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Amoxicillin is a broad spectrum antibiotic. It is rapidly bactericidal and possesses the safety profile of penicillin.
The wide range of organisms sensitive to the bactericidal action of Amoxicillin include:
Aerobes:
Gram-negative
Haemophilus influenzae Escherichia coli Proteus mirabilis Salmonella species Shigella species Bordetella pertussis Brucella species Neisseria gonorrhoeae Neisseria meningitidis Vibrio cholerae Pasteurella septica
Gram-positive
Streptococcus faecalis
Streptococcus pneumoniae
Streptococcus pyogenes
Streptococcus viridans
Staphylococcus aureus (penicillin-sensitive
strains only)
Corynebacterium species Bacillus anthracis Listeria monocytogenes
Anaerobes: Clostridium species
5.2 Pharmacokinetic properties
Amoxicillin is well absorbed by the oral and parenteral routes. Oral administration, usually at convenient t.d.s. dosage, produces high serum levels independent of the time at which food is taken. Amoxicillin gives good penetration into bronchial secretions and high urinary concentrations of unchanged antibiotic.
Amoxicillin is rapidly absorbed when given by mouth; it is not converted to ampicillin. It is widely distributed and is reported to produce peak antibiotic plasma concentrations that are up to twice as high as those from the same dose of ampicillin. Peak plasma-amoxicillin concentrations of about 5 g per ml have been observed 2 hours after a dose of 250 mg, with detectable amounts present for up to 8 hours. Doubling the dose can produce double the concentration. The presence of food in the stomach does not appear to diminish absorption significantly.
Up to 20% is bound to plasma proteins in the circulation and plasma half-lives of about one hour have been reported. Amoxicillin diffuses across the placenta; little appears to be excreted in breast milk. It penetrates will into purulent and mucoid sputum and low concentrations have been found in ocular fluid.
In preterm infants with gestational age 26-33 weeks, the total body clearance after intravenous dosing of amoxicillin, day 3 of life, ranged between 0.75 - 2 ml/min, very similar to the inuline clearance (GFR) in this population. Following oral administration, the absorption pattern and the bioavailability of amoxicillin in small children may be different to that of adults. Consequently, due to the decreased CL,
the exposure is expected to be elevated in this group of patients, although this increase in exposure may in part be diminished by decreased bioavailability when given orally.
