Sulfamethizole falls into category C:

In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans, though. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

There are no well-controlled studies that have been done in pregnant women. Sulfamethizole should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.
