How does potassium supplement interact with other medications or foods?

Potassium supplements can have negative interactions with certain foods and medications. Because potassium is found in foods, you need to be aware of your diet when taking potassium supplementation. Avoid low-sodium foods and salt substitutes; these foods can contain high levels of potassium. Potassium salts may interact with high blood pressure medications, including angiotensin-converting enzyme inhibitors (or ACE inhibitors), angiotensin receptor blockers (or ARBs), in addition to heart failure medications spironolactone and eplerenone. Some penicillin antibiotics also have high concentrations of potassium. Water pills may also have negative interactions with potassium, as can the drug indomethicin. Certain herbal supplements should also be avoided, including dandelion, gossypol and licorice. Always be sure your doctor and pharmacist are aware of all medications and supplements you are taking, even if they are available over-the-counter.
