Description

Zinacef (1.5g) Injection is a broad-spectrum antibiotic supplied as a single vial of sterile powder, packaged with ampoules of sterile water for reconstitution. Its active ingredient is Cefuroxime, delivered as cefuroxime sodium, a second-generation cephalosporin antibiotic known for its resistance to many bacterial enzymes (beta-lactamases) that can inactivate other antibiotics. Zinacef is active against a wide range of both gram-positive and gram-negative bacteria, making it a versatile option for treating infections before the specific causative organism has been identified. It works by disrupting the formation of the bacterial cell wall, leading to bacterial cell death, and is commonly used in hospital settings for both treatment and surgical infection prevention.

Ingredients

Each vial of Zinacef 1.5g contains cefuroxime sodium equivalent to 1.5g of cefuroxime as the active ingredient. The pack typically includes ampoules of sterile water for injection used to reconstitute the powder into a clear solution before dilution and administration.

Dosage Form

Zinacef is presented as a sterile crystalline powder for solution, supplied in a single 1.5g vial together with sterile water for injection, intended for reconstitution and administration by intravenous or deep intramuscular injection.

Uses

Zinacef Injection is used to treat a wide range of bacterial infections, including respiratory tract infections such as bronchitis and pneumonia, ear, nose, and throat infections, urinary tract infections, skin and soft tissue infections, bone and joint infections, and gonorrhea. It is also widely used as a preventive antibiotic given just before certain surgical procedures, including abdominal, pelvic, orthopedic, cardiac, and other operations, to reduce the risk of post-operative infection.

How to Use

Zinacef must be reconstituted and administered only by a trained healthcare professional, either by direct intravenous injection, intravenous infusion after dilution, or deep intramuscular injection into a large muscle. The typical adult dose ranges from 750mg to 1.5g given every 8 hours, with the duration and frequency adjusted according to the severity and type of infection, and further adjusted in patients with reduced kidney function. For surgical infection prevention, a single 1.5g dose is often given intravenously shortly before the procedure begins. This medication should never be self-administered.

Side Effects

Zinacef is generally well tolerated, but side effects can occur. Commonly reported effects include diarrhea, nausea, and local reactions at the injection site, such as pain, particularly after intramuscular administration. Less frequently, patients may experience skin rash, itching, or hives. Rare but more serious effects can include anaphylaxis, colitis, seizures (particularly with very high doses or in patients with kidney impairment), and changes in liver enzymes or blood counts. Prolonged use may also lead to overgrowth of non-susceptible organisms, resulting in secondary infections such as oral thrush. Any signs of severe allergic reaction, persistent diarrhea, or unusual bruising should be reported to a doctor immediately.

Pregnancy & Breastfeeding

Zinacef is generally considered acceptable for use during pregnancy when clearly needed, as controlled studies have not shown clear evidence of fetal risk, though it should still only be used under a doctor’s guidance. Cefuroxime is excreted into breast milk in small amounts, so caution should be exercised, and the treating doctor should be informed if the patient is breastfeeding before treatment begins.

Storage Instructions

Unopened Zinacef vials should be stored below 25°C, protected from light, in their original packaging. Once reconstituted, the solution generally retains potency for around 5 hours at room temperature or up to 48 hours if refrigerated, though exact stability can vary depending on the diluent used. Keep out of the reach of children.
