Key takeaways
Cefdinir (Omnicef) and ceftibuten (Cedax) are both cephalosporin antibiotics used to treat bacterial infections, such as those affecting the lungs, ears, and throat. However, there are several differences between these medications. Cefdinir is still available in generic form and can be prescribed for both adults and children, while ceftibuten is no longer available in the U.S. Cefdinir comes in capsules and oral suspension, whereas ceftibuten was available as an oral suspension before being discontinued. Cefdinir is FDA-approved for a wider range of infections, including pneumonia and skin infections, while ceftibuten was primarily used for bronchitis, otitis media, and throat infections. Common side effects of cefdinir include diarrhea, nausea, and rash, and it has specific drug interactions with antacids and iron supplements. In contrast, ceftibuten's side effects and interactions are not detailed due to its discontinuation. Additionally, cefdinir can be used off-label for urinary tract infections, especially in children, which is not mentioned for ceftibuten.
