Common side effects include nausea, diarrhea, allergic reactions, and pain at the site of injection. Serious side effects may include Clostridium 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 available as a generic medication. A week of treatment when taken by mouth in the United Kingdom costs the NHS about £18 as of 2019. In the United States, the wholesale cost of this amount is about US$8.50. In 2016, it was the 291st most prescribed medication in the United States, with more than a million prescriptions.
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 most other second-generation cephalosporins, cefuroxime can cross the blood-brain barrier.
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, recent assessments have shown no increased risk for a cross-allergic reaction for cefuroxime and several other second-generation or later cephalosporins.
