Cefdinir

Cefdinir, sold under the brand name Omnicef among others, is an antibiotic used to treat bacterial infections including bacterial pneumonia, other respiratory tract infections, otitis media, strep throat, and cellulitis. It may also be used as an alternative antibiotic for those with a severe penicillin allergy. It is taken by mouth. Common side effects include diarrhea, nausea, and a skin rash. Serious side effects may include Clostridioides difficile infection, anaphylaxis, and Stevens–Johnson syndrome. Use in pregnancy and breastfeeding is believed to be safe but has not been well studied. It is a third-generation cephalosporin antibiotic and works by interfering with a bacteria's ability to make a cell wall, resulting in its death.
