What is a potential adverse effect of potassium supplements that patients should be made aware of?

Potassium supplements can lead to hyperkalemia, which is an elevated level of potassium in the bloodstream. This condition can become serious, as excessive potassium levels can have profound effects on the heart and other muscles. Hyperkalemia may result in symptoms such as heart palpitations, muscle weakness, and in severe cases, can lead to dangerous arrhythmias or cardiac arrest.

Patients should be made aware of the risks associated with potassium supplementation, particularly if they have underlying conditions such as kidney disease, which can impair the body’s ability to excrete potassium, further increasing the risk of hyperkalemia. Regular monitoring of potassium levels is typically advised when initiating potassium supplements to preemptively address any potential overload. This highlights the importance of educating patients about the risks of hyperkalemia when they are prescribed potassium supplements.
