Nevertheless, the risk of cross-reactivity is sufficient to warrant the contraindication of all β-lactam antibiotics in patients with a history of severe allergic reactions (urticaria, anaphylaxis, interstitial nephritis) to any β-lactam antibiotic. Rarely, allergic reactions have been triggered by exposure from kissing and sexual contact ...
Common side effects include nausea, diarrhea, constipation, headache, rash, and pain at the site of injection. [3] Serious side effects include Clostridioides difficile infection, seizures, and allergic reactions including anaphylaxis. [3] Those who are allergic to other β-lactam antibiotics are more likely to be allergic to meropenem as well. [3]
Benzylpenicillin, a penicillin. The double bond is absent in the pentacyclic ring. The double bond is absent in the pentacyclic ring. Penem molecules do not occur naturally, and production of penems is an entirely synthetic process.
Rash and allergic reactions; Inhibition of cell wall synthesis Doripenem: Doribax: Imipenem/Cilastatin: Primaxin: Meropenem: Merrem: Cephalosporins (First generation) Cefadroxil: Duricef: Good coverage against Gram-positive infections. Gastrointestinal upset and diarrhea; Nausea (if alcohol taken concurrently) Allergic reactions
Additionally, those with penicillin allergies can usually tolerate cephalosporins (another group of β-lactam) because the immunoglobulin E (IgE) cross-reactivity is only 3%. [5] Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. [6]
Severe side effects may include anaphylaxis, seizures, and Clostridioides difficile-associated diarrhea. [4] It is unclear if use during pregnancy is safe. [5] Meropenem works by blocking the construction of the bacterial cell wall while vaborbactam blocks the breakdown of meropenem by some beta-lactamases. [4]
Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. This has implications for any kind of test or assay , including diagnostic tests in medicine, and can be a cause of false positives .
Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam. [9] Monobactams can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
