To the Editor:
As Dr. Harold S. Koplewicz points out (Op-Ed, March 1), many children and adults are treated with medications that do not have Food and Drug Administration approval. The doctor is responsible for using clinical judgment to insure that a drug is safe and effective for each patient. However, an equally important issue is the risk to children from potentially dangerous substances, like androstenedione, that can be purchased from a health food store or supermarket without a prescription. Unlike pharmaceuticals, these supplements have not been tested on adults.
