How long does it take a single dose of Klor-Con 10MEQ to take maximum effect? Lasts how long ?

You should take it as prescribed. It is usually prescribed on a daily basis to maintain potassium levels. Potassium is an electrolyte. You take potassium in by eating foods that contain potassium (or taking supplements) and you also lose potassium in sweat, urine and if you have vomiting or diarrhea, you can lose it quickly, so the levels of potassium can change but usually there is a balance between what is taken in and what is lost through the kidneys.. I would think, to avoid muscle cramping, you are going to need to take it every day. Once your potassium levels are in the normal range, the cramping will stop now matter when you take the drug. Increased urinary potassium excretion is first observed 1 hour after administration of Klor-Con® Extended-release Tablets, reaches a peak at 4 hours, and extends up to 8 hours. Klor-Con is an extended release tablet and you will pass a wax matrix in your stools that looks like the tablet passing through. This doesnt mean you havent absorbed the medication. The matrix is the carrier for the potassium and all of the drug is released from this matrix before it passes into the stools.

What you're doing Is replacing potassium. You aren't going to feel anything much.
