Cesium and Cortisone Acetate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CORTICOSTEROIDS

Why this applies to Cortisone Acetate

Cortisone Acetate falls under CORTICOSTEROIDS — the group Cesium interacts with.

Theoretically, taking cesium concomitantly with other drugs that deplete potassium, such as corticosteroids, may increase the risk of hypokalemia.
Cesium supplements have been associated with hypokalemia in many case reports.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing about pairing cesium with cortisone acetate: both can lower your potassium levels. Cortisone is a corticosteroid, and steroids like this tend to flush potassium out of the body. Cesium has been tied to low potassium (hypokalemia) in a number of case reports, so stacking the two could push your potassium down even further.

Low potassium isn't something to brush off. It can leave you feeling weak, crampy, and tired, and in more serious cases it can trigger irregular heartbeats. This concern is mostly theoretical and based on anecdotal reports, not strong studies. Honestly, though, cesium chloride itself is risky and isn't proven to treat anything, so please talk with your doctor or pharmacist before going near it.

From our pharmacist’s overview on the Cortisone Acetate page

“Cortisone acetate (Cortone) is an oral corticosteroid, taken to replace missing cortisol or to quiet inflammation, and its supplement list warrants genuine care. Most of the 121 interacting ingredients either rev up the immune system this steroid is meant to calm or change how much of the drug reaches your blood.”

About Cesium

What is Cesium?

  • Marketed as an alternative cancer treatment ('high pH therapy')
  • Claimed to alter tumor pH
  • General 'alkaline' health claims

Cesium chloride is a mineral salt sold as an alternative cancer therapy ('high pH therapy'), but there is no reliable scientific evidence that it treats cancer or any other disease. It can cause dangerous heart rhythm problems and even death, so it should not be used. Talk to your doctor or pharmacist before taking any supplement, and never use cesium in place of proven medical care.
