Category B: Pregnancy-related concerns have not been demonstrated in tests on animals, although such research is inadequate.
 
Category C: Although there aren’t enough well-controlled trials on pregnant women, animal studies have revealed negative consequences, though it’s possible that the potential advantages outweigh the dangers.
