Acetazolamide
"Hypokalemic Periodic Paralysis is an ion channel disorder which causes me to have partial to full body paralysis and daily generalized weakness, not to mention other medical problems. Acetazolamide helps keeps my potassium up (along with Potassium Chloride - immediate release) to a safe level the majority of the time. I have chronic mild metabolic acidosis and have had one kidney stone in the past 16 yrs due to Acetazolamide, but it has been well worth the side effects."
