I am sorry, I really don't have anything to help you. i just have a suggestion. Find out what kind of medications the doctors there have him on, and research them all. look them up in a PDR, or a pill book that can be purchased at any grocery, or drug store. You can also look them up online, however all of the information online may be scattered or hard to find. I would look into one of the books, so you have it handy. The pill book is not expensive, probably 12 dollars at the most. Good luck to you!Please let us know how he is doing!
