How long do potassium supplements last in the body for, when are they eliminated? i was given 2 pills bc my potassium level was 3.2

All the time: The potassium's a normal electrolyte and constantly is eliminated by the kidneys, the amount of oral ingestion of potassium and the kidney elimination achieve adequate balance. Generally, we give potassium supplements every 8 hours but your physician should check your levels and make some urine test to know if your kidneys arent's eliminating a lot of potassium.
