Sometimes you may see what appears to be a whole tablet in the stool after taking certain extended-release potassium chloride tablets. This is to be expected. Your body has absorbed the potassium from the tablet and the shell is then expelled.
Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.
Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
