I have just been diagnosed with a high level of potassium. The medicine (prescription) that I have been given costs over $100 for a 10 day supply. What is the cheapest but effective medicine that I can be on? I will restrict my diet to exclude bananas, nuts, beans, milk, beef, potatoes, apricots and cod which should help reduce my level. Appreciate any help you can give me relative to price. Thanks, Paul Etienne at YYYY@YYYY or 208-500-1688
