What do you suggest if my son is taking the growth hormone drug, norditropin, (human growth hormone) and after 3 months is getting ringworm constantly.?

Likely unrelated: The side effect profile of growth hormone includes dry skin and rash, but susceptibility to ringworm is not related to use of growth hormone. More likely, he is being exposed to a classmate, or an animal with a ringworm and constantly getting reinfected. Also, has it been diagnosed by his doc as a ringworm? Some forms of eczema look a lot like ringworm! See your doc for definitive answers.
