Metadate Side Effects

The documented risks of these drugs are provided so the public can make informed, educated decisions. Metadate is a stimulant drug, classified by the U.S. Drug Enforcement Administration (DEA) as Schedule II, in the same class of highly addictive drugs as morphine, opium and cocaine. The DEA states that the use of stimulants can lead to “severe psychological or physical dependence” and that “these drugs are also considered dangerous.” Metadate is also known as Concerta, Concerta LP, Concerta Oros, Daytrana, Equasym, Equasym XL, Metadate CD, Metadate ER, Methylin, Methylin ER, Methylphenidate, Ritalin, Ritalin LA, Ritalin SR.

Please note: No one should attempt to get off of psychiatric drugs without a doctor’s supervision.

Also, read the FDA’s Metadate Medication Guide for more information. MedGuides include “the particular serious and significant public health concern that has created the need for the Medication Guide” and notes “pediatric risks.”
