In summary, oral amoxicillin is safe in the majority of cephalexin allergic or intolerant subjects.
Can you take penicillin if you are allergic to cephalosporin?
Type 1 cephalosporin-allergic patients should probably not be challenged with a penicillin for mild-to-moderate infections. A negative skin test more than 1 year after their immediate reaction may not be reliable.
What other antibiotics are cephalosporins related to?
Cephalosporins are related to the structure and antimicrobial activity of penicillins. Both groups of antibiotics possess the core four-membered β-lactam ring. The β-lactam ring in penicillins is connected to a five-membered thiazolidine ring, or penam, and the side chain, R, differentiates the different penicillins.
Is amoxicillin a cephalosporin?
While cephalexin and amoxicillin are each beta-lactam antibiotics, they are not the same. Cephalexin is a cephalosporin antibiotic, and amoxicillin is a penicillin derivative. While they cover some of the same bacterial organisms, they each cover unique organisms.

The most common allergic reactions to cephalosporins are maculopapular or morbilliform rash, drug fever, and a positive Coombs’ test. Urticaria, serum-sickness–type reactions (rash plus polyarthritis), and anaphylaxis are less common (see accompanying table).

How do cephalosporins kill bacteria?
Cephalosporins are bactericidal drugs, meaning they kill bacteria directly. They do this by interfering with how bacteria build their cell walls. Cephalosporins are grouped into five generations based on when the drugs were developed. In general, each generation is effective against certain types of bacteria.
What is a substitute for amoxicillin?
For those patients with mild sensitivity to amoxicillin, acceptable alternatives include cefdinir (Omnicef), cefpodoxime (Cefzil), or cefuroxime (Ceftin). These agents, along with amoxicillin-clavulanate (Augmentin), are also commonly used as second or third line therapy.
Is there a stronger antibiotic than amoxicillin?
Choosing the Right Antibiotic for an Infection
