What are the side effects of Cloxacillin?
Cloxacillin may cause a range of adverse reactions, from mild to severe.
Common Side Effects: - Injection site pain or phlebitis - Rash or mild skin eruption - Diarrhea or loose stools - Nausea or vomiting - Elevated liver enzymes
Serious or Rare Side Effects: - Anaphylaxis or severe allergic reaction - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Clostridioides difficile‑associated colitis - Hemolytic anemia - Neutropenia or agranulocytosis
What precautions apply to Cloxacillin?
Before using Monoclox, consider the following precautions to ensure safe and effective therapy. - Allergy assessment: confirm no known hypersensitivity to penicillins or beta‑lactam antibiotics. - Liver function monitoring: check baseline enzymes and repeat if clinically indicated. - Renal function monitoring: adjust dosing in patients with impaired renal clearance. - History of colitis: use cautiously in individuals with prior C. difficile infection. - Concomitant nephrotoxic drugs: avoid or monitor closely when combined with aminoglycosides or NSAIDs. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.
What does Cloxacillin interact with?
Cloxacillin can interact with several medicines, affecting efficacy or safety.
Major Interactions (Avoid): - Methotrexate: increased toxicity and reduced clearance. - Oral contraceptives: reduced hormonal efficacy, risk of unintended pregnancy. - Warfarin: enhanced anticoagulant effect, increased INR.
Moderate Interactions (Monitor Closely): - Aminoglycosides: additive nephrotoxicity, monitor renal function. - Loop diuretics: may affect renal handling, watch electrolytes. - Probenecid: decreases renal excretion of cloxacillin, raise plasma levels. - Tetracyclines: antagonistic antibacterial activity, may reduce effectiveness.
