Concerta Side Effects
Curious about Concerta side effects? Concerta is an extended release form of methylphenidate. Therefore, the Concerta side effects will be similar to those of Ritalin and other methylphenidate formulations. The drug manufacturer recommends that caution be used if/when giving Concerta to people who have a history of drug dependence or alcoholism. This is because long term drug and alcohol abuse can lead to a marked tolerance and psychological dependence on Concerta resulting in varying degrees of abnormal behavior including, but not limited to, psychotic episodes.
