I would like to hear from anyone who has used prednisone (Deltasone) or acyclovir (Zovirax) on their children for autism. Prednisone is a steroid and acyclovir is an antiviral. I have been considering using either or both of these meds on my 10 year old son but I am concerned about the side effects. I would appreciated hearing from anyone who could give me some information through past experience to help me decide. I would like to know information like age of child, any positive or negative effects, was the child autistic at birth or regressed later in childhood, any history of seizures or abnormal EEGs, and any regression after discontinuation of therapy. Thanks in advance to anyone who responds.
