Interactions: Kalimate

Dietary
  • Mix the sodium polystyrene sulfonate powder with water, or with honey or jam to make it taste better.
  • Avoid inhaling the oral powder while you are preparing a dose.
  • Do not mix the powder with any juice or other liquid that contains potassium, such as orange juice.
  • The potassium in foods will bind with the resin preventing adequate potassium removal from patients with hyperkalemia.
Supplementation
  • 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
Antacids & Laxatives
  • alkalosis following concurrent administration of cation-exchange resins and non-absorbable cation-donating antacids and laxatives such as magnesium hydroxide and aluminium carbonate.
  • Intestinal obstruction due to concretions of aluminium hydroxide has been reported when aluminium hydroxide has been combined with the resin (sodium form).
  • Management: Monitor for signs/symptoms of intestinal obstruction with concomitant use of calcium polystyrene sulfonate and aluminum hydroxide.
  • Adequate fluid intake, laxative use, alternative antacid agents, and/or limiting duration of therapy may help reduce risks
Sorbitol
  • Concomitant use of Sorbitol with calcium polystyrene sulfonate is not recommended due to cases of intestinal necrosis and other serious gastrointestinal adverse reactions, which may be fatal
