What to do to increase my potassium levels?

Prescription only: Over the counter potassium pills are very weak to make a dent in significantly low potassium. Only prescriptions are effective and need to be followed with blood testing to prevent under or overdosing - both are dangerous. Potassium rich diet is also weak. It includes potatoes, tomato sauce/paste, bananas, oranges, and squash. There are meds that make you retain potassium from being lost in urine.
