Indications & Uses

Pharmacology

Flucloxacillin is active against Gram-positive organisms, including strains that produce penicillinase, though it has little effect on Gram-negative bacilli. It works by blocking formation of the bacterial cell wall. As an isoxazolyl penicillin, it combines resistance to breakdown by penicillinase with stability in stomach acid and activity against Gram-positive bacteria, making it a bactericidal antibiotic that is especially useful against penicillinase-producing staphylococci.

More specifically, Flucloxacillin disrupts the bacterial cell wall by interfering with the synthesis of peptidoglycan, the heteropolymeric structure that gives the cell wall its mechanical strength. The final step of peptidoglycan synthesis is the cross-linking of the terminal glycine residue of the pentaglycine bridge to the fourth residue (D-alanine) of the pentapeptide, a step carried out by the transpeptidase enzyme. Flucloxacillin inhibits this enzyme, so the cell wall is weakened and the bacterial cell swells and eventually ruptures. It is thought to resist bacterial penicillinase because of steric hindrance from its acyl side chain, which prevents the beta-lactam ring from being opened.

Cautions & Contraindications

Warnings & Precautions

S-Fluclox should be used carefully in patients with signs of liver problems. It should also be used with caution when treating patients who have a tendency toward allergic reactions.

Contraindications

Flucloxacillin should not be used in patients who are hypersensitive to penicillin.

Pregnancy & Breastfeeding

Pregnancy and Breastfeeding: Flucloxacillin falls under US FDA Pregnancy Category B. There are no adequate, well-controlled studies of its use in pregnant women, and because animal studies don't always predict how humans will respond, it should only be used during pregnancy when clearly necessary. Flucloxacillin also passes into breast milk, so it should be given to breastfeeding mothers with caution.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Use in Special Populations

If a patient has severe renal failure (creatinine clearance below 10 ml/min), the doctor should consider giving Flucloxacillin Sodium at a lower dose or leaving a longer gap between doses.

Storage

Store Flucloxacillin Sodium in a dry place, away from light and heat. Always keep it out of the reach of children.
