    Streptococcal pharyngitis/tonsilitis
    30mg/kg once daily over at least ten days.

    Patients with Renal Impairment

    Dosage should be adjusted according to estimated glomerular filtration rate (eGFR).

    No dosage adjustment is required in patients with eGFR greater than 50ml/minute/1.73 metre squared.

    Dosage schedule for adults with renal impairment is suggested below:

    eGFR 25 to 50 ml/minute/1.73 metre squared
    1g initially followed by 500mg to 1g every 12 hours.

    eGFR 10 to 25 ml/minute/1.73 metre squared
    1g initially followed by 500mg to 1g every 24 hours.

    eGFR 0 to 10 ml/minute/1.73 metre squared
    1g initially followed by 500mg to 1g every 36 hours.

    Cefadroxil is removed by haemodialysis. An additional dose of 500mg to 1g should be given at the end of haemodialysis (in adults).


    Children under 6 years

    Precautions and Warnings

    History of allergies including anaphylaxis
    History of gastrointestinal disorder
    Renal impairment - eGFR below 50ml/ minute/ 1.73m squared
    Ulcerative colitis

    Advise ability to drive/operate machinery may be affected by side effects
    Before initiating therapy enquire about previous hypersensitivity reactions
    Consult national/regional policy on the use of anti-infectives
    Monitor liver function on prolonged therapy
    Monitor renal function during prolonged/high dose therapy
    Perform blood counts on prolonged use of this treatment
    Consider pseudomembranous colitis if patient presents with diarrhoea
    Prolonged use may result in superinfection with non-susceptible organisms
    May cause false positive Coomb's test and glycosuria test
    Neonate exposed in utero: Risk of false positive Coomb's test
    Discontinue if drug-related rash or other hypersensitivity reactions occur

    Pregnancy and Lactation


    Safety of cefadroxil administration during pregnancy has not been established. Animal studies and clinical experience have not shown any evidence of teratogenicity. Cephalosporins are usually considered safe to use during pregnancy.

    Cephalosporins cross the placenta, and can reach therapeutic levels in amniotic fluid and fetal tissues.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14-17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( ) or if this is unavailable at the backup site ( ).


    Use with caution while breastfeeding. Cefadroxil is excreted in low concentrations in human breast milk.

    Occasionally, disruption of the infant's gastrointestinal flora, resulting in diarrhoea or thrush, has been reported with cephalosporins, however, these effects have not been adequately evaluated.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.

    It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
