The Uses and Effects of Cefuroxime

10 January, 2021
When administering this antibiotic, it's important to keep in mind that there are a number of population groups for whom the effects of cefuroxime could cause serious problems.

If you’ve ever had an ear or throat infection, or even a urinary infection, your doctor may have prescribed cefuroxime to treat this discomfort. Cefuroxime is an antibiotic drug that belongs to the cephalosporin family. Specifically, it’s a second generation cephalosporin. But what does that mean? And what are the effects of cefuroxime?

What are antibiotics?

Antibotics for urinary tract infections.

A good understanding of this term is essential to understanding how cefuroxime works and what its origin is. Therefore, the term antibiotic refers to chemicals, or their synthetic derivatives,  that a living being produces, that kill or prevent the growth of certain classes of sensitive microorganisms.

We also know them as antibacterials since we often use them to fight infections caused by bacteria. In this sense, they aim to eradicate or kill bacteria, or inhibit their growth.

To do this, they have different mechanisms of action. Some affect the synthesis of proteins, others the synthesis of DNA, and others the cell wall, for example.

Depending on the mechanism of action they trigger, they belong to one family or another. In this case, cefuroxime belongs to the family of beta-lactams, which we’ll look at later.

Finally, it’s worth mentioning the importance of avoiding self-medication with antibiotics. This practice poses a serious problem at a personal and public health level.

Beta-lactams

Beta-lactams are the antibiotics that owe their action to their ability to inhibit the synthesis of peptidoglycan from the cell wall. In particular, they inhibit the process of transpeptidation.

To do this, they need to enter the cell so that they can produce their effect. Once inside, they bind to penicillin-binding proteins.

Antibiotics belonging to this group are reduced spectrum drugs, that is, they’re only effective against gram-positive bacteria. In addition, they’re bactericides, which means that they kill the pathogen.

On the other hand, they’re drugs that we can administer both orally and parenterally. They have a good safety record and, although they can cross the placenta, they’re first-choice drugs in pregnancy because of their good safety profile.

Among the most common are:

  • Penicillins
  • Cephalosporins: This is the group that cefuroxime belongs to
  • Monobactams: Active against gram-negative bacteria

The use of cefuroxime

First of all, it’s worth repeating that cefuroxime is part of the cephalosporin subfamily. That is, antibiotics that are similar to penicillin but that, unlike penicillin, perform better against certain bacteria, as pointed out by the Magazine of the Faculty of Medicine of Caracas, Venezuela.

Basically, doctors use cefuroxime to treat infections caused by bacteria that are susceptible to beta-lactam antibiotics. For this reason, it presents an antimicrobial activity against microorganisms such as the following:

  • Haemophilus influenzae
  • Neisseria gonorrhoeae
  • Borrelia burgdoferi

It’s prescribed when this type of bacteria triggers an infection in the ears, throat, sinuses, urinary tract, and even in the skin.

Adverse reactions

Like other cephalosporins, cefuroxime administration can trigger a number of adverse effects. Normally, those of a gastrointestinal nature predominate. In that sense, the adverse effects of cefuroxime can include the following:

  • Discomfort
  • Stomach pain
  • Vomiting
  • Diarrhea

Interestingly, some patients suffering from cephalosporins allergy have been detected in about 10% of the population allergic to penicillin. Nevertheless, a crossed allergy between penicillin and cefuroxime and other second and more recent generations cephalosporins hasn’t been demonstrated.

Cautions regarding the use of cefuroxime

When administering this antibiotic, it’s important to keep in mind that there are a number of population groups for whom the effects of cefuroxime could cause serious problems. Among these situations that require special caution we can mention the following:

  • Hypersensitivity reactions: Before starting treatment, the doctor should ask if the patient has a history of severe hypersensitivity reactions to cefuroxime, other cephalosporins or any beta-lactam agent. Caution is advised if cefuroxime is administered to patients with a history of non-severe hypersensitivity to other beta-lactam agents.
  • Jarisch-Herxheimer reaction: This reaction may be triggered after the treatment of Lyme disease with cefuroxime. The reaction originates directly from the bactericidal activity of cefuroxime on the bacterium causing Lyme disease, Borrelia burgdoferi.
  • Overgrowth of non-sensitive microorganisms: The use of cefuroxime could lead to an overinfection produced by Candida. Moreover, prolonged use could also trigger a proliferation of microorganisms not sensitive to this antibiotic which would require the interruption of the treatment.
  • Interference with diagnostic tests: Treatment with this antibiotic could alter the results of some diagnostic tests. For example, with cross blood tests.

Use of cefuroxime only by prescription

Cefuroxime is an antibiotic belonging to the cephalosporin family. It inhibits the synthesis of the cell wall of sensitive bacteria, thus causing their death.

A rational use should be made both of this drug and of any other antibiotic. Self-medication and the abuse of these substances are causing a great public health problem and great complications in the clinical development of new antimicrobial drugs.
