When a child or adult stops taking Concerta, he may experience anxiety, irritability, insomnia and increased blood pressure.
Serious Side Effects
-
While other adverse effects of Concerta are less common, they can be more serious. These effects include seizures, glaucoma, drug dependence, bowel obstruction and psychiatric disorders.
