Augmentin and Omnicef are different types of antibiotics—Augmentin is a penicillin antibiotic, while Omnicef is a cephalosporin. While they are not the same, people who are allergic to cephalosporins like Omnicef may also be allergic to penicillins like Augmentin. Therefore, if you have a known allergy to Omnicef or other cephalosporins, you should avoid Augmentin to reduce the risk of a severe allergic reaction. Always consult your healthcare provider before you buy augmentin online or start any new antibiotic.
