# Can Klor-Con (potassium chloride extended-release) be crushed?

## Direct answer

**NO. Do not crush.** Klor-Con, Klor-Con M, and K-Tab are on the ISMP “Do Not Crush” list as extended-release tablets; concentrated potassium released all at once can irritate the GI tract. FDA labeling for Klor-Con M instead allows breaking the tablet in half or dissolving the whole tablet in water for patients who have trouble swallowing.

Formulation: Extended-release tablet

## What to ask the pharmacist

Ask the pharmacist about the label-approved dissolve-in-water method for Klor-Con M, or a potassium liquid or powder formulation.
