A member asked:

What is the difference between amoxicillin vs cefdinir?

Specializes in Family Medicine

Different family: Amoxicillin belongs in the penicillin family where as Cefdinir belongs in the cephalosporin family. There is some cross reactivity when it comes to allergies; they both kill bacteria by affecting cell wall, but they are different.
