I am a 32 year old female, s/p roux-en-y gastric bypass in Dec 2013. In August, my potassium became very low (2.9). I was started on klor-con 20mEq and initially took 1 tab daily. I have since had that increased to 60mEq daily because my body is not maintaining potassium levels (3.3 and under on 40mEq). I have seen my pcp and an endocrinologist and we have so far been unable to find the cause of potassium dumping. The endo believes it might be related to the RNY. I ran out of my Rx and had difficulty getting it refilled because of provider vacations, etc. I have been very symptomatic. I resumed taking it today but I was wondering how long it takes for the klor-con to start taking effect? I know it is different for everyone, and it s hard to guess because of the dosage I have to take + my history, but I am just looking for a more typical timeline.
