# Cefuroxime

Cefuroxime, sold under the brand name Zinacef among others, is a second-generation cephalosporin antibiotic used to treat and prevent a number of bacterial infections. These include pneumonia, meningitis, otitis media, sepsis, urinary tract infections, and Lyme disease. It is used by mouth or by injection into a vein or muscle.
Common side effects include nausea, diarrhea, allergic reactions, and pain at the site of injection. Serious side effects may include Clostridioides difficile infection, anaphylaxis, and Stevens–Johnson syndrome. Use in pregnancy and breastfeeding is believed to be safe. It is a second-generation cephalosporin and works by interfering with a bacteria's ability to make a cell wall resulting in its death.
Cefuroxime was patented in 1971 and approved for medical use in 1977. It is on the World Health Organization's List of Essential Medicines. In 2022, it was the 283rd most commonly prescribed medication in the United States, with more than 600,000 prescriptions.

## Medical uses

Cefuroxime is active against many bacteria including susceptible strains of Staphylococci and Streptococci, as well as a range of gram negative organisms. As with the other cephalosporins, it is susceptible to beta-lactamase, although as a second-generation variety, it is less so. Hence, it may have greater activity against Haemophilus influenzae, Neisseria gonorrhoeae, and Lyme disease. Unlike other second-generation cephalosporins, cefuroxime can cross the blood–brain barrier.
A systematic review found high quality evidence that injecting the eye with cefuroxime after cataract surgery will lower the chance of developing endophthalmitis after surgery.

## Side effects

Cefuroxime is generally well tolerated, and its side effects are usually transient. If ingested after food, this antibiotic is both better absorbed and less likely to cause its most common side effects of diarrhea, nausea, vomiting, headaches/migraines, dizziness, and abdominal pain compared to most antibiotics in its class.
Although a widely stated cross-allergic risk of about 10% exists between cephalosporins and penicillin, an assessment in 2006 have shown no increased risk for a cross-allergic reaction for cefuroxime and several other second-generation or later cephalosporins.
