Pregnancy and Lactation
Pregnancy
Use patiromer calcium with caution during pregnancy.

The manufacturer advises that it is preferable to avoid its use as a precautionary measure although animal studies have not indicated any harmful effects either directly or indirectly.
Lactation
Use patiromer calcium with caution during breastfeeding.
The manufacturer recommends that a decision must be made whether to discontinue breastfeeding or to discontinue patiromer taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.
