How much Dex is your son taking? That more than likely is the cause of his weight. If it were my child I would prefer Cortef. Dex is so very potent. I took .25mg for 12 years, now I take Cortef and I wish I knew this sooner. My daughter also has locah and take 12.5mg of Cortef.

 The Dex can also cause depression and anxiety. It is not your sons fault, it’s the meds. He cannot help what is happening to him.
