Cefazolin has been shown to be effective in treating methicillin-susceptible Staphylococcus aureus (MSSA) but does not work in cases of methicillin-resistant Staphylococcus aureus (MRSA). [8] In many instances of staphylococcal infections, such as bacteremia, cefazolin is an alternative to penicillin in patients who are allergic to penicillin. [9]
Cefdinir, sold under the brand name Omnicef among others, is an antibiotic used to treat pneumonia, otitis media, strep throat, and cellulitis. [1] It is a less preferred option for pneumonia, otitis media, and strep throat which may be used in those with a severe penicillin allergy. [1]
Skin allergy to cefaclor. The principal side effect of the cephalosporins is hypersensitivity. Penicillin-sensitive patients may also be allergic to the cephalosporins, depending on the side chain and it's relation to the penicillin allergy. Most patients with penicillin allergy can tolerate the majority of cephalosporins without allergic ...
Cefalexin is a useful alternative to penicillins in patients with penicillin intolerance. For example, penicillin is the treatment of choice for respiratory tract infections caused by Streptococcus , but cefalexin may be used as an alternative in penicillin-intolerant patients. [ 4 ]
Cephalosporin C, which has a similar structure to penicillin N, was never commercialized. Cephalosporin C was a lead compound for the discovery and production of many other cephalosporins. [ 2 ] Cephalosporins are drugs used for some people who are allergic to penicillin.
The so-called delabeling of penicillin allergies, doctors say, would have major health impacts: faster and more effective treatments for people who have spent their lives avoiding penicillin and ...
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
