Medicine for high alkaline phosphatase levels?

Wrong approach: Alkaline phosphatase is a lab value to tell a physician what is happening, not a medical problem to treat. It can be high just because you're growing (teens tend to be maybe 5x the upper limit of the reference range). About 5% of older folks have a high alk phos for "no reason", presumably paget's of the bone that never becomes evident; nonfasting samples may have it from the intestine.
