Salt substitutes (for example, Mrs. Dash) often contain potassium. Therefore, using salt substitutes while taking potassium supplements may lead to high levels of potassium in the blood.
Drugs that slow transit of food through the intestine, for example, atropine and loperamide (Imodium), may delay passage of potassium tablets through the digestive system and result in ulceration or narrowing of the small intestine.
PREGNANCY: Potassium supplementation has not been adequately evaluated in pregnant women.
NURSING MOTHERS: If the mother's blood potassium level is normal, use of potassium supplements should not adversely affect the infant.
