What side effect may occur with administration of potassium supplements?

The administration of potassium supplements can lead to cardiac arrhythmias as a potential side effect. This occurs because potassium plays a crucial role in maintaining proper electrical activity in the heart. An imbalance, whether too much or too little potassium, can disrupt normal heart rhythms, potentially leading to arrhythmias.

It is important to monitor potassium levels in individuals receiving supplements, as both hypokalemia (low potassium) and hyperkalemia (high potassium) can cause serious cardiac complications. Healthcare providers often perform regular checks on electrolyte levels to ensure that they remain within a safe range, especially in patients who are at higher risk for heart-related issues.

While other symptoms such as gastrointestinal issues might be observed with potassium supplementation, such as nausea or diarrhea, they are not as critical as the risk of cardiac arrhythmias that can arise from improper potassium levels.
