Long-Term Effects

  • See "What Are Side Effects Associated with Using Patiromer?"


  • Patiromer binds many orally administered medications, which could decrease their gastrointestinal (GI) absorption and lead to reduced efficacy
  • Avoid use with severe constipation, bowel obstruction, or impaction, including abnormal post-operative bowel motility disorders; patiromer may be ineffective with these conditions present and may worsen GI conditions
  • Patients with a history of bowel obstruction or major GI surgery, severe GI disorders, or swallowing disorders were not included in clinical trials
  • Binds to magnesium in the colon, which can lead to hypomagnesemia; monitor serum magnesium; consider magnesium supplementation if low serum magnesium levels observed

Pregnancy and Lactation

  • Patiromer is not absorbed systemically following oral administration, and maternal use during pregnancy is not expected to result in fetal risk.
  • Patiromer is not absorbed systemically by the mother, so breastfeeding is not expected to result in a risk to the infant.
