Tell your doctor or pharmacist if you are regularly taking other medications that can also raise your potassium level.

Swallow the capsules or tablets whole. Do not crush, or chew extended-release capsules or tablets. Doing so can release all of the drug at once, increasing the risk of side effects.

Swallow the capsules whole. If you have trouble swallowing the capsules, tell your doctor or pharmacist. Some brands may be opened and the contents sprinkled onto a spoonful of cool, soft food such as applesauce or pudding. Immediately swallow the food/medication mixture without chewing. Do not prepare the mixture ahead of time. Drink a glass of cool water after each dose to make sure you swallow all the medication. Ask your pharmacist if you have questions about your brand.
