At one time it was believed that stimulant medications, used for prolonged periods of time, could interfere with growth.
In fact, it was for this reason that some physicians began recommending “drug holidays” to allow for a period of catch up growth.
However, most scientific studies suggest that medications for ADD do not significantly impact on growth. In those that have shown some impact on growth, the magnitude of the change is actually miniscule.
I monitor height and weight every three months in all patients for whom I am prescribing medication. After treating thousands of patients over many years, I have yet to see the first patient where medication treatment for ADD could be blamed for an alteration in growth.
Actually, my observations of growth patterns in children and adolescents with ADD are in sync with recent research. Many children with ADD have a relative deceleration of their growth rate as they approach and enter into puberty and tend to experience their growth spurt at a later point in puberty compared to their non-ADD peers.
Depending upon the age when ADD medication is instituted, this “normal ADD growth pattern” should be taken into account when interpreting any changes in growth rate that might occur.
