Treatment for Attention Deficit Disorder:
The most common treatment for ADD is a combination of medication and behavioral therapy.  In the case of mild ADD, behavioral therapy and behavioral modification is enough.  In more severe cases, medication such as Ritilan, Adderal or Dexedrine is used in conjunction with behavioral therapy.  Concerta, a 12 hour version of Ritilan, has recently been approved for use with ADD patients and many parents are finding this a good choice for their children as it does not require any medication to be given at school.
The use of any medication should be supervised by a physician with any side affects reported immediately.  Some common side affects of Ritilan and Adderal are loss of appetite, irritability, mood swings, and in some cases increased agression.
It is also important to note that teachers CANNOT make a parent put a child on medication, but they can make a recommendation that the child be tested for ADD.  The decision to medicate must ultimately be made by the parent and the physician working together.
