Does intake of potassium chloride cause cardiac arrest?

Question

Hi doctor,

By mistake, I had potassium chloride powder of 5 mL today, just before an hour. When I checked on the internet, it says that it may cause cardiac arrest. How true is that? What should I do now to avoid any side effect?

Hi,

Welcome to icliniq.com. If you do not have any kidney dysfunction, then there is nothing to worry about. 5 mL will provide potassium equivalent to around 50 to 60 meq, and our body can excrete that amount if there are no previous kidney and cardiac complaints. It may cause acidity, so ensure you drink adequate plain water. Avoid potassium-rich foods like coconut water and fruits for three days. Rest assured, you will be fine.
