<s>[INST] I was given a dose of potassium because my level was at 3.2 and had another blood test 2 days later and my count was up to 4 and my blood surgar fasting was at 115 my question is how long does the potassium the hospital last until my level starts going back down? [/INST] Hi, dairy have gone through your question. I can understand your concern. Your potassium level is very low. Life-threatening arrhythmia can occur with this level.  You should take potassium dosage till your potassium level become normal and stable.  Serial monitoring is needed.  Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
