What is in this leaflet
This leaflet answers some common questions about CONCERTA extended-release tablets. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you or your child taking CONCERTA against the benefits this medicine is expected to have for you or your child.
If you have any concerns about taking CONCERTA ask your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
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 hydrochloride.
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.
