Patient's Query

Hi doctor,

I was not prescribed by my doctor to have a Potassium chloride tablet. But I had one tablet per day for the past two days. Is it fine to take? What will be the side effect? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

Potassium chloride tablets should not be taken without monitoring. Serum potassium level should be done once every three days. Hyperkalemia (elevated level of potassium) is a very dangerous thing. It can precipitate many sorts of arrhythmias (abnormal heartbeats), and excessive levels can even be fatal. You have not mentioned the reason for which you had Potassium chloride tablets. Do you have hypokalemia, or are you on diuretics? As of now, as per your query, potassium tablets should not be taken without monitoring your serum potassium level.

I hope this helps.

Please revert so I can assist you further.

Thank you.
