ValerieHey Diane -
I just thought I would let you know that our Dr told us that we should not use PB. This was in case if there was steroid induced gastritis (sp?) - like an ulcer- there is an ingredient in PB that is similar to aspirin and could cause Ryes syndrome!!! So, he said to use another over-the-counter med like Zantac or Pepcid.
Also, make sure you give Charlie things to coat his stomach when he takes meds, i.e. milk or something like that (not acidic things like juices).
Good luck and hope Charlie is feeling better soon.
