Paediatric population
Children
Proportionately lower doses should be given in children.
Usual children’s dosage
2–10 years: half adult dose
Under 2 years: quarter adult dose.
Abnormal renal function:
In common with other penicillins, Flucloxacillin usage in patients with renal impairment does not usually require dosage reduction. However, in the presence of severe renal failure (creatinine clearance <10 ml/min) a reduction in dose or an extension of dose interval should be considered. The maximum recommended dose in adults is 1 g every 8 to 12 hours.
Flucloxacillin is not significantly removed by dialysis and hence no supplementary dosages need to be administered either during, or at the end of the dialysis period.
Hepatic impairment
Dose reduction in patients with reduced hepatic function is not necessary.
Method of administration
Add 1.5 ml Water for Injections to 250 mg vial contents or 2 ml Water for Injections to 500 mg vial contents.

Dissolve 250–500 mg in 5–10 ml Water for Injections or 1–2g in 15–20 ml Water for Injections.

1. what flucloxacillin is and what it is used for
Flucloxacillin is an antibiotic belonging to the group known as penicillins. Antibiotics are used to kill the bacteria or “germs” which cause infections. Flucloxacillin can be given as an injection or breathed-in using a nebulizer (a device used to give a medicine as a liquid mist).
Flucloxacillin is given to treat a wide range of infections caused by bacteria which may include:
- skin and soft tissue ( boils, abscesses, carbuncles, impetigo, cellulitis, furunculosis, ulcers, eczema and acne)
- wounds, burns, heart (endocarditis)
- ears (otitis media and otitis external)
- those affecting the chest (pneumonia, emphysema and lung abscess)
- sinuses (sinusitis)
- pharynx (pharyngitis)
- tonsils (tonsillitis, quinsy)
- bones and joints (osteomyelitis)
- gut (enteritis)
- membranes of the brain (meningitis)
- blood (septicaemia) and the kidney, bladder or the urethra (the tube which carries urine from the bladder).
Flucloxacillin may also be used to prevent infections following skin graft or during major surgical procedures, particularly in heart or orthopaedic surgery.
2. what you need to know before you are given flucloxacillin
You should not be given Flucloxacillin if you:
- are allergic to flucloxacillin or any other penicillin antibiotics (see symptoms section 4)
- have ever had an allergic reaction to any of the other ingredients of this medicine – see list of ingredients in section 6
- have had liver problems after taking this medicine (flucloxacillin)
Warning and precautions
suffer from liver problems- suffer from kidney problems, as you may require a lower dose than normal
- are 50 years or over
- have other serious illnesses (apart from the infection this medicine is treating)
- have human immunodeficiency virus (HIV)
- are taking or will be taking paracetamol.
There is a risk of blood and fluid abnormality (high anion gap metabolic acidosis) which occurs when there is an increase in plasma acidity, when flucloxacillin is used concomitantly with paracetamol, particularly in certain groups of patients at risk, e.g. patients with severe renal impairment, sepsis or malnutrition, especially if the maximum daily doses of paracetamol are used. High anion gap metabolic acidosis is a serious disease that must have urgent treatment.
Other medicines and Flucloxacillin:
Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Especially:
- Probenecid(used to treat gout)
- Other antibiotics (used to treat infections)
Some medicines may affect the way others work. Always tell your doctor about all the medicines you are taking. This means medicines you have bought yourself as well as medicines on prescription from a doctor.
Pregnancy and breast-feeding:
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Tests
Regular monitoring of liver and kidney function should be performed whilst taking flucloxacillin for a long period of time. Tell your doctor that you are taking Flucloxacillin if you are having urine tests or blood tests because it may affect the results.
Driving and using machines:
There should be no effect on the ability to drive and operate machinery.
Important information about some of the ingredients of Flucloxacillin:
Flucloxacillin contains sodium (51 mg per gram). This should be taken into consideration if you are on a low sodium diet.

It can also be given to you by injection into a joint (intra-articular) or injection into the lining of the lung (intrapleural), or by breathing in the medicine from a mask (nebuliser). Flucloxacillin should not be administered into the eye.

For treatment of infections inside the bones (osteomyelitis) or infections inside the heart (endocarditis) the amount of flucloxacillin may be increased up to 8 g each day, and given in equal doses every six to eight hours.
Prevention of infection during operations
- between 1 g to 2 g, given into a vein, just as you receive your anaesthetic. A further dose of 500 mg every six hours will be given for up to 72 hours.
