Key takeaways
Cefditoren (Spectracef) and sulfamethoxazole/trimethoprim (Bactrim, Septra) are both antibiotics used to treat bacterial infections, including lung infections like bronchitis and pneumonia. However, they belong to different medication classes. Cefditoren is a cephalosporin antibiotic, while sulfamethoxazole/trimethoprim is a combination of a sulfonamide and an antifolate. Cefditoren is no longer available in the U.S., whereas sulfamethoxazole/trimethoprim is still available as a generic and under various brand names. Sulfamethoxazole/trimethoprim can be taken orally or as an injection, while cefditoren was only available in oral form. Common side effects of sulfamethoxazole/trimethoprim include nausea, diarrhea, and rash, and it can interact with many medications, such as warfarin. In contrast, cefditoren's side effects and interactions are less detailed due to its discontinuation. Additionally, sulfamethoxazole/trimethoprim is not recommended during pregnancy and should be avoided if you have a sulfa allergy, while such specific warnings are not mentioned for cefditoren.
