What is CONCERTA used for
CONCERTA is used to treat Attention Deficit Hyperactivity Disorder (ADHD). CONCERTA is part of a comprehensive treatment
program which usually includes psychological, educational and social therapy.
CONCERTA is a stimulant that increases attention and decreases impulsiveness and hyperactivity in patients with ADHD.
CONCERTA should be used as part of a total treatment program for ADHD that may include counselling or other therapies.
CONCERTA should not be used in children less than 6 years old because it has not been studied in this age group.
CONCERTA tablets are made in an extended release form. This means that they release the active ingredient slowly. The outer
layer of the CONCERTA tablet dissolves right after it is swallowed in the morning, giving an initial dose of methylphenidate
The tablets have a special shell that allows the rest of the methylphenidate hydrochloride to be released from the tablet
at a slow rate throughout the day.
The tablet shell does not dissolve completely after all the drug has been released and sometimes the tablet shell may be seen
in your stool. This is normal.
Your doctor may have prescribed CONCERTA for another reason. Ask your doctor if you have any questions about why this medicine
has been prescribed for you/your child.
CONCERTA can be abused or lead to dependence. Keep CONCERTA in a safe place to prevent misuse and abuse.
