Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Sevelamer 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.

Breastfeeding

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if sevelamer is excreted in human breast milk or if it will harm your nursing baby.
