All penicillins inhibit the biosynthesis of the bacterial cell wall. Flucloxacillin is highly resistant to inactivation by staphylococcal penicillinase and is active against penicillinase-producing and non penicillinase-producing strains of Staphylococcus aureus.

CONTRAINDICATIONS:

  • A history of allergic reaction to any of the penicillins is a contraindication.


WARNINGS
Anaphylaxis
Penicillins are a common cause of anaphylactic reactions
Pseudomembranous colitis
Pseudomembranous colitis has been reported with nearly all antibacterial agents, including flucloxacillin, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhoea subsequent to the administration of antibacterial agents.

PRECAUTIONS
General
Prescribing Flucloxacillin in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug resistant bacteria.

Laboratory Tests:
No tests in addition to routine ICU tests are required.

Drug/Laboratory Test Interactions
None noted.

Tetracycline, a bacteriostatic antibiotic, may antagonise the bactericidal effect of penicillin and concurrent use of these drugs should be avoided.

Body as a Whole:
Serum sickness like reactions, Anaphylaxis
Digestive System:
Nausea, vomiting, diarrhoea, and haemorrhagic/pseudomembranous colitis. Hepatic dysfunction including cholestatic jaundice, hepatic cholestasis and acute cytolytic hepatitis have been reported.
Nervous System:
Reversible hyperactivity, agitation, anxiety, insomnia, confusion, convulsions, behavioural changes, and/or dizziness have been reported rarely.
Skin:
Stevens-Johnson Syndrome, exfoliative dermatitis, toxic epidermal necrolysis, acute generalised exanthematous pustulosis, hypersensitivity vasculitis and urticaria have been reported
Haematological System:
Anaemia, including haemolytic anaemia, thrombocytopaenia, thrombocytopaenic purpura, eosinophilia, leukopaenia, and agranulocytosis have been reported during therapy with penicillins.
