Potassium Chloride: Uses, Side Effects, and Drug Interactions
Brand names: Potassium Chloride
# Potassium Chloride Overview Potassium chloride is a medicine used to treat low potassium levels in the body. Potassium is an important mineral that helps your heart, muscles, and nerves work properly. When your body doesn't have enough potassium, it can cause serious health problems. Doctors prescribe potassium chloride to replace the potassium you're missing, either because your body isn't getting enough from food or because certain medicines or health conditions have caused your potassium levels to drop too low. This medicine is safe when used correctly, but it's important to follow your doctor's instructions carefully. You should never take potassium chloride with certain other medicines, including some blood pressure medications like triamterene or amiloride, because combining them can cause dangerously high potassium levels. Other medicines like NSAIDs (pain relievers) and certain blood pressure drugs may also affect how your body handles potassium, so your doctor may need to watch your potassium levels more closely. Always tell your doctor about all the medicines you're taking before using potassium chloride to make sure it's safe for you.
