Kefzol

Cefazolin, the active ingredient in Kefzol, is a cephalosporin presented as a sterile powder for reconstitution for intravenous or intramuscular use. It is employed to treat a range of bacterial infections and to prevent postoperative infections in surgical patients. GNH USA supplies Kefzol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Cefazolin is a broad‑spectrum cephalosporin used primarily for infections caused by susceptible Gram‑positive and some Gram‑negative bacteria. - Surgical prophylaxis: prevents postoperative infections caused by susceptible organisms. - Skin and soft‑tissue infections: treats cellulitis and wound infections. - Bone and joint infections: used for osteomyelitis and septic arthritis. - Urinary tract infections: effective against uncomplicated UTIs caused by susceptible pathogens.

Cefazolin may cause a variety of adverse reactions, ranging from mild to severe.

Common Side Effects: - Injection site pain or phlebitis: discomfort at the infusion site. - Rash or urticaria: mild skin eruptions. - Diarrhea or nausea: gastrointestinal upset. - Transient elevation of liver enzymes: mild hepatic changes.

Serious or Rare Side Effects: - Anaphylaxis: severe, potentially life‑threatening allergic reaction. - Clostridioides difficile‑associated diarrhea: severe colitis. - Stevens‑Johnson syndrome or toxic epidermal necrolysis: serious skin disorders. - Hemolytic anemia or renal impairment: rare hematologic or renal complications.

Cefazolin should be used with caution in specific clinical situations. - Renal function: adjust dose in patients with impaired renal clearance. - Allergy history: avoid in individuals with known penicillin or cephalosporin hypersensitivity. - Pregnancy and lactation: prescribe only if the potential benefit justifies the potential risk to the fetus or infant. - Superinfection risk: monitor for secondary infections such as fungal overgrowth. - Store at ambient temperature: keep in original container, protect from moisture and light.

Cefazolin can interact with several medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Aminoglycosides: increased risk of nephrotoxicity when combined. - Loop diuretics: may enhance ototoxic effects. - Warfarin: potential augmentation of anticoagulant effect.

Moderate Interactions (Monitor Closely): - Probenecid: reduces renal excretion, raising cefazolin levels. - Oral contraceptives: may decrease hormonal efficacy. - Methotrexate: heightened risk of toxicity due to reduced clearance.
