Sodium polystyrene sulfonate Rectal and Multivitamins with minerals

Sodium polystyrene sulfonate can bind to calcium, iron, magnesium, and other minerals in the gastrointestinal tract. This may inactivate both sodium polystyrene sulfonate and the mineral it binds to and reduce the effectiveness of both medications. To avoid or minimize the interaction, the dosing times of sodium polystyrene sulfonate and multivitamin with minerals should be separated by several hours. Talk to your doctor if you have any questions or concerns, or if you have trouble separating the dosing times. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

ADJUST DOSING INTERVAL: Simultaneous administration of cation-donating preparations may reduce the potassium exchange capability of cation-exchange resins due to binding of the cation to the resin.

MANAGEMENT: Patients should consider separating the times of administration of the cation-exchange resin and any cation-donating preparation (e.g., mineral supplements; antacids; products containing antacids such as didanosine buffered tablets or pediatric oral solution) by several hours if possible.
