Cefdinir has been assigned to pregnancy category B by the FDA. Animal studies have revealed evidence of maternal toxicity (decreased body weight gain) and decreased fetal body weight. There are no controlled data in human pregnancy. Cefdinir should be given during pregnancy only if need is clearly established.
