Information for children and young people with ADHD
Now read the rest of this leaflet before you start taking this medicine.
Metyrol XL contains the active substance ‘methylphenidate hydrochloride’. It belongs to a group of medicines known as psychostimulants.
Metyrol XL is used to treat ‘Attention Deficit Hyperactivity Disorder’ (ADHD).
Metyrol XL is not for use as a treatment for ADHD in children under 6 years of age or in patients older than 60 years. It is not known if it is safe or of benefit in these age groups.
Metyrol XL improves the activity of certain parts of the brain which are under-active. The medicine can help improve attention (attention span), concentration, and reduce impulsive behaviour.
The medicine is given as part of a treatment programme, which usually includes:
Metyrol XL treatment must only be initiated by, and used under the supervision of a doctor, specialised in the treatment of ADHD, such as an expert paediatrician, a child and adolescent psychiatrist or a psychiatrist. A thorough examination is necessary.
If you are an adult and have not been treated before, the specialist will carry out tests to confirm that you have had ADHD since childhood. Using treatment programmes as well as medicine helps to manage ADHD.
Contact your doctor if you or your child do not feel any improvement or if you or your child feel worse.
Children and young people with ADHD find it hard:
It is not their fault that they cannot do these things.
Many children and young people struggle to do these things. However, with ADHD they can cause problems with everyday life. Children and young people with ADHD may have difficulty learning and doing homework. They find it hard to behave well at home, at school or in other places.
Adults with ADHD often find it hard to concentrate. They often feel restless, impatient and inattentive. They may have difficulty organising their private life and work.
ADHD does not affect intelligence.
Not all patients with ADHD need to be treated with medicine, and the decision to treat with Metyrol XL requires a very thorough assessment of the severity and duration of the patient’s symptoms in relation to age.
Your doctor will regularly check your (or your child’s) health while being treated with Metyrol XL (please read carefully section 3, “Things your doctor will do when you or your child are on treatment”).
Do not take methylphenidate if any of the above apply to you or your child. If you are not sure, talk to your doctor or pharmacist before taking methylphenidate. This is because methylphenidate can make these problems worse.
Talk to your doctor or pharmacist before taking Metyrol XL if you or your child:
Tell your doctor or pharmacist if any of the above apply to you or your child before starting treatment. This is because methylphenidate can make these problems worse. Your doctor will want to monitor how the medicine affects you or your child.
If you or your child develop blurred vision or other visual disturbances contact your doctor. Your doctor may consider discontinuation of Metyrol XL.
These checks are to decide if methylphenidate is the correct medicine for you or your child. Your doctor will talk to you about:
It is important that you provide as much information as you can. This will help your doctor decide if methylphenidate is the correct medicine for you or your child. Your doctor may decide that other medical tests are needed before you or your child start taking this medicine.
If you or your child have or have had heart problems before starting treatment or develop heart symptoms during treatment with Metyrol XL, tell your doctor immediately, who will refer you to a heart specialist.
During treatment, boys and men may unexpectedly experience prolonged erections. This may be painful and can occur at any time. It is important to contact your doctor straight away if the erection lasts for longer than 2 hours, particularly if this is painful
Tell your doctor or pharmacist if you or your child are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
Do not take Metyrol XL if you or your child:
If you or your child are taking other medicines, methylphenidate may affect how well they work or may cause side effects. It may therefore be necessary to adjust the dosage of the medicine or stop taking it altogether. If you or your child are taking any of the following medicines, check with your doctor or pharmacist before taking methylphenidate:
If you are in any doubt about whether any medicines you or your child are taking are included in the list above, ask your doctor or pharmacist before taking Metyrol XL.
Tell your doctor if you or your child are going to have an operation. Methylphenidate should not be taken on the day of surgery if a certain type of anaesthetic is used. This is because there is a chance of a sudden rise in blood pressure and heart rate during the operation.
This medicine may give a positive result when testing for drug use.
Metyrol XL may be taken with or without food. Taking this medicine with food may help to stop stomach pains, feeling sick or being sick. If you or your child notice a decrease in appetite while taking this medication, try to avoid taking it just before a meal. Instead, try taking it with food or after finishing eating.
Do not drink alcohol while taking this medicine. Alcohol may make the side effects of this medicine worse. Remember that some foods and medicines contain alcohol.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Available data do not suggest an increased risk of overall birth defects, whilst a small increase in the risk of malformations of the heart when used during the first three months of pregnancy could not be ruled out. Your doctor will be able to give you more information about this risk.
Tell your doctor or pharmacist before taking this medicine if you or your daughter are:
You or your child may feel dizzy or drowsy, have problems focusing the eyes or have blurred vision, or have hallucinations, or other central nervous system side effects when taking methylphenidate. If these happen it may be dangerous to do things such as drive, use machines, ride a bike or horse or climb trees.
If you have been told by your doctor that you or your child have an intolerance to some sugars, contact your doctor before taking this medicinal product.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

If you or your child are unable to swallow Metyrol XL, you can sprinkle the contents on a small amount of food, as follows:
Do not store any medicine/food mixture for future use.
