Thank you for your question and welcome to ADHDCentral.
Prozac has been approved for treatment of depression in children 8 years of age and older and for the treatment of Obsessive Compulsive Disorder in children ages 7 and up.
On my second visit to the psychiatrist today she prescribed 10mg of Prozac for my 5 year old. I am choosing not to give it to him and wait a few months to see if anything changes in his maturity. His symptoms are ... anger, frustration, anxiety, mood changes etc.... all of which I see VERY little at home and all things happen at preschool and have since he was 3. I think it's a lot of maturity. Question? Why would a psychiatrist prescribe this to a 43 pound little 5 year old?
It is impossible for me to say why your doctor would prescribe this medication for your son. I am sure it was done based on information you supplied regarding behaviors etc. Even though this medication has been approved for children over 7/8, it doesn't necessarily mean it is not safe for a younger child, it means that there are not enough studies in children that age. (I am not saying you should or should not give your child the medication, this is certainly your choice.)
