Kefzol

Cefazolin, the active ingredient in Kefzol, is a first‑generation cephalosporin presented as a sterile injectable solution for intravenous use. It treats a range of bacterial infections and is commonly employed for surgical prophylaxis and serious infections in adult patients.

GNH USA supplies Kefzol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Cefazolin is a first‑generation cephalosporin used to treat infections caused by susceptible bacteria.

- Surgical prophylaxis: prevents postoperative bacterial infections in patients undergoing surgery. - Urinary tract infections: eradicates causative organisms and resolves infection symptoms. - Skin and soft tissue infections: treats cellulitis, abscesses and wound infections. - Respiratory tract infections: effective against community‑acquired pneumonia and bronchitis. - Bone and joint infections: used for osteomyelitis and septic arthritis caused by susceptible strains.

Cefazolin may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Injection site reactions: pain, erythema, or swelling at the infusion site. - Gastrointestinal upset: nausea, vomiting, or diarrhea. - Transient elevation of liver enzymes: mild increase in ALT or AST. - Hypersensitivity rash: mild skin rash or itching.

Serious or Rare Side Effects: - Anaphylaxis: severe, life‑threatening allergic reaction with hypotension and airway compromise. - Clostridioides difficile colitis: severe diarrhea due to overgrowth of C. difficile. - Hemolytic anemia: immune‑mediated destruction of red blood cells.

When using Cefazolin, clinicians should consider several safety measures.

- Renal impairment: dose adjustment may be required in patients with reduced kidney function. - Allergy history: avoid in patients with known cephalosporin or penicillin hypersensitivity. - Pregnancy and lactation: use only if clearly needed, as safety data are limited. - Concurrent nephrotoxic drugs: monitor renal function when combined with aminoglycosides or NSAIDs. - Superinfection: watch for secondary infections such as fungal or resistant bacterial overgrowth. - Store at ambient temperature: keep below 25 °C, protect from light and moisture, and retain in original packaging.

Cefazolin can interact with other medicines, requiring attention to dosing and monitoring.

Major Interactions (Avoid): - Aminoglycosides: increased risk of nephrotoxicity; avoid concurrent high‑dose therapy. - Loop diuretics: may potentiate renal toxicity; monitor kidney function. - Warfarin: cefazolin may enhance anticoagulant effect; check INR frequently.

Moderate Interactions (Monitor Closely): - Probenecid: may reduce renal clearance of cefazolin; adjust dose if needed. - Oral contraceptives: possible reduction in efficacy; advise alternative contraception. - Live vaccines: may diminish vaccine response; schedule vaccinations appropriately.
