- Skin and soft tissue infections: effective against cellulitis, abscesses and wound infections caused by susceptible Staphylococcus aureus. - Bone and joint infections: used in osteomyelitis and septic arthritis when the pathogen is cloxacillin‑sensitive. - Endocarditis: indicated for native‑valve endocarditis due to penicillin‑resistant Staphylococcus species.
What are the side effects of Cloxacillin?
Adverse reactions may occur with cloxacillin therapy.
Common Side Effects: - Diarrhea - Nausea - Rash - Injection site pain
Serious or Rare Side Effects: - Anaphylaxis - Severe neutropenia - Clostridioides difficile‑associated colitis
What precautions apply to Cloxacillin?
Cloxacillin requires careful monitoring in several clinical situations.
- Renal function: adjust dosing in patients with impaired kidney function. - Hepatic function: monitor liver enzymes during prolonged therapy. - Allergy: avoid in individuals with known penicillin hypersensitivity. - Concurrent antibiotics: assess for potential antagonism or additive toxicity. - Pregnancy and lactation: use only if the expected benefit outweighs potential risk. - Store at ambient temperature: keep in the original container, protect from light and moisture.
What does Cloxacillin interact with?
Cloxacillin can interact with other medicines, necessitating vigilance.
Major Interactions (Avoid): - Methoxyflurane: may increase nephrotoxicity. - Probenecid: reduces renal excretion, raising cloxacillin levels. - Oral contraceptives: may reduce hormonal efficacy.
Moderate Interactions (Monitor Closely): - Aminoglycosides: additive risk of kidney injury. - Warfarin: monitor INR as cloxacillin can enhance anticoagulant effect.
