Concerta is a stimulant drug that has various side effects such as dry mouth and weight loss. There are also drug interactions which can occur when the drug is combined with substances such as antidepressants and other central nervous system stimulants.

Methylphenidate (brand name Concerta) is a central nervous system (CNS) stimulant medication used to help control symptoms associated with attention deficit hyperactivity disorder (ADHD) such as impulsivity. 

In addition to treating ADHD symptoms, Concerta may be used to treat excessive sleepiness or a condition known as narcolepsy.
