Cephalexin vs Amoxicillin
Cephalexin is the first generation cephalosporin, also having a beta-lactam ring with bactericidal activity. This is the main use for gram-positive coccus infections, such as otitis media due to Streptococcus pneumoniae, streptococcal pharyngitis, cellulitis, some other skin infections such as impetigo. Note that because of its beta-lactam ring, many bacteria resistant to amoxicillin or other penicillins can also be resistant to cephalexin; some people have an allergy to the beta-lactam ring, that is, there may be cross-reactivity, and people who are allergic to penicillin / amoxicillin may also be allergic to cephalexin.
Amoxicillin is a semi-synthetic penicillin, which has a beta-lactam ring with bactericidal activity. This is the main use for bacterial pharyngitis (also called “strep throat” due to the fact that most of them are caused by Streptococcus), acute otitis media and treatment of ambulatory pneumonia. People who are allergic to penicillin have a decent likelihood of allergy to amoxicillin.
