Before using patiromer

Tell your doctor if you have ever had any unusual or allergic reaction to patiromer or any other medicines.

For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of patiromer in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of patiromer in the elderly.
