Is there a pregnancy category assigned to Cefdinir?

Cefdinir, a cephalosporin antibiotic, has been classified by the FDA in a way that reflects its safety profile during pregnancy. Specifically, it does not have a designated pregnancy category due to a lack of sufficient human data to establish its safety. As a result, it falls under the classification of "None assigned," indicating that there is no definitive evidence regarding its effects on fetal development. This situation often arises with certain drugs where preclinical studies may suggest safety, but human clinical trials are lacking or insufficient to provide a clear category assignment. Therefore, when considering the use of cefdinir during pregnancy, it's essential to weigh the potential benefits against any unknown risks, as no formal category designation has been established.
