The oral version of Kayexalate can reduce the effectiveness of many orally-administered prescription drugs if consumed simultaneously. This medication has harmed many people by not having conflicted drugs listed on the label.

About Kayexalate

KayexalateApproved in 1958, Kayexalate (sodium polystyrene sulfonate) treats hyperkalemia. This condition causes a high amount of potassium in the blood. Left untreated hyperkalemia can cause heart rhythm problems. Also, in some cases these are fatal. Keyexalate binds to the extra potassium in the intestines, and then, the body eliminates it.

Kayexalate Harmful Interactions

In September 2017, the FDA warned that orally-administered Kayexalate can conflict with other oral medications. The agency made the warning after evaluating findings of a laboratory study. Researchers studied the binding potential for six orally administered medicines commonly taken together with sodium polystyrene sulfonate:

  • Amlodipine (Norvasc)
  • Metoprolol (Lopressor and Toprol XL)
  • Amoxicillin
  • Furosemide (Lasix)
  • Phenytoin (Dilantin, Phenytek)
  • Warfarin (Coumadin)

The study found that significant binding to sodium polystyrene sulfonate occurred with all of the medicines. The results led the FDA to conclude that sodium polystyrene sulfonate would probably bind to many other oral medicines, reducing their effectiveness.

FDA Orders Label Update for Kayexalate

Kayexalate LabelThe FDA is now recommending patients not take oral versions of Kayexalate and other sodium polystyrene sulfonate products at the same time as other orally-administered drugs. The agency also increased the time window of consuming other drugs to six hours. The FDA also ordered that the labels for Kayexalate and generic versions be updated with information about dosing separation.

$10M Kayexalate Lawsuit

A Maryland jury in a medical malpractice lawsuit awarded $10 million to the estate and surviving family members of a pastor who died after treatment for liver and kidney problems at a Baltimore City hospital. The 63-year-old man went to the hospital for dialysis and treatment of rhabdomysolysis. This condition causes the death of muscle fibers and releases their contents into the bloodstream. Because of that, this process causes kidney failure.

Then, in the hospital, the man had elevated potassium levels and received Kayexalate. The medication caused irreversible colon damage. Also, the prescribing physician was unaware of the risks.
