I am glad to hear they are taking him off the Lorazepam. I am surprised they prescribed the older Prozac. Maybe they have more experience with Prozac with adolescents since it has been on the market for so much longer.

Did they test his B-12, Folate and vit D levels?

How about his adrenal functions?

Sounds like they are looking hard to find the cause of his symptoms.

Try to relax and be patient. It is also very frustrating for him and your stress and frustration is likely obvious to him. I know it is difficult, especially with a mother's heart.

My best to you.
