What Is The Prescribed Dosage Of Potassium Chloride?

Hi, may I answer your health queries right now ? Please type your query here...Hello I have been taking potassium chloride and I have read and heard that if I take took much of it that it will kill me by stopping my heart. My question is how much is too much to take? I was also told that if it is injected in you it will kill you is this true and if so tell me how much because I am very scared now to take it because I was told to mix it with water and give an injection how much is too much for an injection?
