1. What Xenidate XL is and what it is used for

What it is used for

Xenidate XL is used to treat "attention deficit hyperactivity disorder" (ADHD).

• it is used in children and young people between the ages of 6 and 18.

• it is used only after trying treatments which do not involve medicines. Such as counselling and behavioural therapy.

Xenidate XL is not for use as a treatment for ADHD in children under 6 years of age or for the initiation of treatment in adults. When treatment was started at a younger age, it might be appropriate to continue taking Xenidate XL when you become an adult. Your doctor will advise you about this.

How it works

Xenidate XL improves the activity of certain parts of the brain which are underactive. 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:

• psychological,

• educational, and

• social therapy.

It is prescribed only by doctors who have experience in children or young people's behaviour problems. Although there is no cure for ADHD, it can be managed using treatment programmes.

About ADHD

Children and young people with ADHD find it hard:

• to sit still, and

• to concentrate.

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.

ADHD does not affect the intelligence of a child or young person.

2. What you need to know before you or your child takes Xenidate XL

• are allergic to methylphenidate or any of the other ingredients of this medicine (listed in section 6),

• have a thyroid problem,

• have increased pressure in the eye (glaucoma),

• have a tumour of the adrenal gland (phaeochromocytoma),

• have an eating problem when you or your child do not feel hungry or want to eat - such as "anorexia nervosa",

• have very high blood pressure or narrowing of the blood vessels, which can cause pain in the arms and legs,

• have ever had heart problems - such as a heart attack, uneven heartbeat, pain and discomfort in the chest, heart failure, heart disease or were born with a heart problem,

• have or have had a problem with the blood vessels in your brain - such as a stroke, swelling and weakening of part of a blood vessel (aneurysm), narrow or blocked blood vessels, or inflammation of the blood vessels (vasculitis),

• are currently taking or have taken within the last 14 days an antidepressant (known as a monoamine oxidase inhibitor)- see "Other medicines and Xenidate XL",

* signs of a severe mood problem like: o feeling like killing yourself,
