Patient leaflet - Methylphenidate Hydrochloride 10 mg tablets
1. What Methylphenidate is and what it is used for
whether there is a family history of 'tics' (hard-to-control,
repeated twitching of any parts of the body or repeating sounds and words)
any mental health or behaviour problems you, your child or
other family members have ever had. Your doctor will discuss whether you or your child are at risk of having mood swings (from being manic to being depressed -called 'bipolar disorder'). They will check your or your child's mental health history, and check if any of your family have a history of suicide, bipolar disorder, or depression.
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 Methylphenidate, tell your doctor immediately, who will refer you to a heart specialist.
Methylphenidate contains the active substance 'methylphenidate hydrochloride'. It belongs to a group of medicines known as psychostimulants.
What it is used for
Methylphenidate is used to treat 'Attention Deficit Hyperactivity Disorder' (ADHD).
It is used in children and young people aged 6 years and
over and in adults.
It is used only after trying treatments which do not involve
medicines, Such as counselling and behavioural therapy and which have been insufficient.
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. Other medicines and Methylphenidate
Tell your doctor or pharmacist if you or your child are taking, have recently taken or might take any other medicines.
Do not take methylphenidate if you or your child:
are taking a medicine called a 'monoamine oxidase inhibitor'
(MAOI) used for depression, or have taken an MAOI in the last 14 days. Taking an MAOI with methylphenidate may cause a sudden increase in blood pressure.
Methylphenidate 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.
How it works
Methylphenidate 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:
- psychological
- educational and
- social therapy.
Methylphenidate 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.
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 to 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:
- other medicines for depression
medicines for severe mental health problems (e.g. to treat
schizophrenia)
- medicines for epilepsy
- medicines used to reduce or increase blood pressure
some cough and cold remedies which contain medicines
that can affect blood pressure. It is important to check with your pharmacist when you buy any of these products
- medicines that thin the blood to prevent blood clots 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 methylphenidate.
Having an operation
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.
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.
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 Methylphenidate requires a very thorough assessment of the severity and duration of the patient's symptoms in relation to age.
Examinations during treatment with Methylphenidate
Your doctor will regularly check your (or your child's) health while being treated with Methylphenidate (please read carefully section 3, 'Things your doctor will do when you or your child are on treatment').
