Understanding the risk of using medications for attention deficit hyperactivity disorder with respect to physical growth and cardiovascular function.

The effects of stimulant medications and atomoxetine on physical growth and on cardiovascular function are reviewed in light of the most recent data, with attention to clinical implications and research needs. Although these medications have a favorable benefit/risk profile and do not induce clinically significant changes in growth or cardiovascular function in the majority of cases, careful patient monitoring is needed to identify individuals at risk for negative outcomes. More research is needed to elucidate the mechanism of growth suppression to estimate better the risk for rare but life-threatening events and test the effectiveness of monitoring procedures.
