This medicine should be used regularly at evenly spaced intervals as per the schedule prescribed by your doctor. Do not skip any doses and finish the full course of treatment even if you feel better. Stopping the medicine too early may lead to the infection returning or worsening. The total duration of treatment and precise dosage will be decided by your doctor, depending on the type of infection that you have and how well you respond to the medication. Before taking this medicine, inform your doctor if you are allergic to penicillin or penicillin-type of medicine. Nausea, vomiting, diarrhea, and local pain, swelling, and redness at the site of injection may be seen as side effects in some patients. These are temporary and usually resolve quickly. Consult your doctor if any of these side effects persist or if your condition worsens. This medicine is generally regarded as safe to use during pregnancy if used under a doctor’s supervision.

Should be taken on an empty stomach. Take on an empty stomach ½-1 hr before meals. Reconstitution: Dissolve 250-500 mg in 5-10 mL water for inj or 1 g in 15-20 mL water for in. For IV infusion, further dilute in suitable IV fluids (e.g. water for inj, NaCl 0.9%, glucose 5%, NaCl 0.18% w/ glucose 4%).
Adults (including elderly patients): Oral: 250-500mg 3-4 times a day. Intravenous IV 0.25-1 g 4 times/day, may double in severe cases. Up to 8 g/day in 3-4 divided doses may be given for osteomyelitis. Up to 8 g/day in 4 divided doses for endocarditis in patients weighing <85 kg and 12 g/day in 6 divided doses for patients weighing >85 kg.
Children have been given doses of 12.5-25 mg/kg body weight 4 times a day. Intravenous 2-10 years: Half of the adult dose Under 2 years: One-fourth of the adult dose
Renal impairment: CrCl (ml/min) <10 Dosage adjustment may be necessary.
Hypersensitivity to penicillins. Porphyria.
Mode of Action
Flucloxacillin inhibits the 3rd and last step of bacterial cell wall synthesis by binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall. It is active against penicillinase-producing and non-penicillinase-producing staphylococci.
Very high doses in poor renal function (risk of neurotoxicity) or heart failure. Avoid contact, skin sensitization may occur. Monitor serum potassium concentration and renal and hematological status. Spirochete infections particularly syphilis; suprainfection with penicillin-resistant organisms with prolonged use; avoid intrathecal route; elderly. Hepatic impairment.
Hypersensitivity reactions including urticaria; fever; joint pains; rashes; angioedema; serum sickness-like reactions; hemolytic anemia; interstitial nephritis; neutropenia; thrombocytopenia; CNS toxicity including convulsions; diarrhea; antibiotic-associated colitis; hepatitis, cholestatic jaundice; agranulocytosis; phlebitis (IV infusion). Potentially Fatal: Anaphylaxis. Stevens-Johnson syndrome
May increase the risk of methotrexate toxicity. May decrease the efficacy of estrogen-containing OC. Enhanced plasma concentrations w/ probenecid. Bacteriostatic drugs (e.g. chloramphenicol, tetracycline) may interfere w/ the bactericidal effect of flucloxacillin. May prolong bleeding time in patients on oral anticoagulants.
