RenaGel falls into category C. Studies in animals have shown a harmful and undesired effect on the unborn baby, yet there are no adequate and well-controlled studies in pregnant women. 

This medication may be given to a pregnant woman if her healthcare provider believes that its benefits to the pregnant woman outweigh any possible risks to her unborn baby.
