Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about CONCERTA modified 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 is not recommended for use in children less than 6 years and elderly over 65 years because it has not been studied in these age groups.

CONCERTA tablets are made in an modified 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.

  • are/is or have/has been alcohol or drug dependent
  • have/has seizures or fits
  • have/has heart problems
    Heart-related problems including sudden death in patients who have heart problems or heart defects, stroke and heart attack in adults and increased blood pressure and heart rate have been reported with the use of methylphenidate, the active ingredient in CONCERTA.
  • have / had thoughts about suicide or attempted suicide
  • have/has high blood pressure

Your doctor may need to adjust the dose or adapt your treatment if you/your child have any of these conditions.

If you have not told your doctor or pharmacist about any of the above, tell them before you/your child start taking CONCERTA.

Taking other medicines:

Tell your doctor or pharmacist if you/your child are taking any other medicines, including medicines you can buy without a prescription from a pharmacy, supermarket or health food shop.

In particular, tell your doctor or pharmacist if you/your child are taking any of the following:

  • Monoamine oxidase (MAO) inhibitors such as phenelzine, selegiline
  • medicines that increase blood pressure
  • medicines used to treat depression or anxiety such as venlafaxine, sertraline, amitriptyline and imipramine
  • medicines used to treat high blood pressure. CONCERTA may decrease the effectiveness of these medicines and your doctor may check your blood pressure and change your dose of antihypertensive medicine.
  • medicines used for anaesthesia. CONCERTA should not be taken with certain anaesthetics on the day of the operation, as there is a chance of a sudden rise in blood pressure and heart rate during the operation. Tell your doctor if you are going to have an operation.
  • medicines used to prevent seizures such as phenytoin, phenobarbitone, primidone and valproate.
  • antipsychotic medicines such as olanzapine, risperidone and quetiapine used to improve the symptoms of certain types of mental illness, e.g. schizophrenia and bipolar disorder.

These medicines may be affected by CONCERTA or may affect how well CONCERTA works. Your doctor or pharmacist can tell you what to do if you/your child are taking any of these medicines.


Follow the directions given to you by your doctor and pharmacist. These directions may differ from the information contained in this leaflet.

While you are taking CONCERTA

Things you must do

  • Always follow your doctor’s instructions carefully

  • Parents and/or caregivers should be alert for the development of thoughts or acts of self-harm, hallucinations, abnormal thinking (psychosis) or new or worsening hostility.
