Information for children and young people
Now read the rest of this leaflet before you start taking this medicine because it contains important information for you.
Affenid is used to treat ‘attention deficit hyperactivity disorder’ (ADHD):
- It is used in children 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.
Affenid is not for use as a treatment for ADHD in children under 6 years of age.
Affenid 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:
- educational and
- social therapy.
It is prescribed only by doctors who have experience in children, adolescents or adults with behaviour problems. 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.
Although there is no cure for ADHD, it can be managed using treatment programmes.
Children and adolescents 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 adolescents struggle to do these things.
However, ADHD can cause problems with everyday life. Children and adolescents 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.
Not all patients with ADHD need to be treated with medicine.
ADHD does not affect intelligence.
- 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 your eye (glaucoma)
- have a tumour of your adrenal gland (phaeochromocytoma)
- have an eating problem where you 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 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 Affenid’
- have mental health problems such as:
- a ‘psychopathic’ or ‘borderline personality’ problem
- abnormal thoughts or visions or an illness called ‘schizophrenia’
- signs of a severe mood problem like:
- feeling like killing yourself
- severe depression, where you feel very sad, worthless and hopeless
- mania, where you feel unusually excitable, over-active, and un-inhibited.
Do not take Affenid if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before you take Affenid.
This is because Affenid can make these problems worse.
Talk to your doctor before taking Affenid if you:
- have liver or kidney problems
- have a problem with swallowing or swallowing whole tablets
- have a narrowing or blockage of your gut or food-pipe
- have had fits (seizures, convulsions, epilepsy) or any abnormal brain scans (EEGs)
- have ever abused or been dependent on alcohol, prescription medicines or street drugs
- are a girl and have started your periods (see the ‘Pregnancy, breast-feeding and contraception’ section below)
- have hard-to-control, repeated twitching of any parts of the body or you repeat sounds and words
- have high blood pressure
- have a heart problem which is not in the ‘Do not take’ section above
- have a mental health problem which is not in the ‘Do not take’ section above.
Other mental health problems include:
- mood swings (from being manic to being depressed -called ‘bipolar disorder’)
- feeling aggressive or hostile
- seeing, hearing or feeling things that are not there (hallucinations)
- believing things that are not true (delusions)
- feeling unusually suspicious (paranoia)
- feeling agitated, anxious or tense
- feeling depressed or guilty.
Tell your doctor or pharmacist if any of the above apply to you before starting treatment. This is because Affenid can make these problems worse. Your doctor will want to monitor how the medicine affects you.
During treatment, boys and adolescents 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 your erection lasts for longer than 2 hours, particularly if this is painful.
These checks are to decide if Affenid is the correct medicine for you. Your doctor will talk to you about:
- any other medicines you are taking
- whether there is any family history of sudden unexplained death
- any other medical problems (such as heart problems) you or your family may have
- how you are feeling, such as feeling high or low, having strange thoughts or if you have had any of these feelings in the past
- 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 or other family members have ever had. Your doctor will discuss whether you are at risk of having mood swings (from being manic to being depressed - called ‘bipolar disorder’). They will check your 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 Affenid is the correct medicine for you. Your doctor may decide that other medical tests are needed before you start taking this medicine. For adult patients that are new to Affenid, your doctor may refer you to a heart specialist.
Tell your doctor if you are taking, have recently taken or might take any other medicines.
Do not take Affenid if you:
- 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 Affenid may cause a sudden increase in your blood pressure (see “Do not take Affenid”).
Tell your doctor or pharmacist if you or your child is taking any of the following medicines for depression or anxiety:
- tricyclic antidepressant
- selective serotonin reuptake inhibitor (SSRI)
- serotonin and norepinephrine reuptake inhibitor’ (SNRI).
Taking Affenid with these types of medicine could cause a life-threatening increase of ‘serotonin’ in the brain (serotonin syndrome), which may lead to feeling confused or restless, sweating, shivering, muscle jerks or fast heart-beat. If you develop these side effects, see a doctor straight away.
If you are taking other medicines, Affenid may affect how well they work or may cause side effects. If you are taking any of the following medicines, check with your doctor or pharmacist before taking Affenid:
- medicines for severe mental health problems
- medicines for Parkinson’s disease (such as levodopa)
- 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 are taking are included in the list above, ask your doctor or pharmacist before taking Affenid.
Please tell you doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Tell your doctor if you are going to have an operation. You should not take Affenid on the day of your surgery if a certain type of anaesthetic is used. This is because there is a chance of a sudden rise in blood pressure during the operation.
This medicine may give a positive result when testing for drug use.
This includes testing used in sport.
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 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 using Affenid if you are:
- having sex. Your doctor will discuss contraception with you
- pregnant or think you may be pregnant. Your doctor will decide whether you should take Affenid.
- breast-feeding or planning to breast-feed. Affenid passes into breast milk. Therefore, your doctor will decide whether you should breast-feed while taking Affenid.
You may feel dizzy, have problems focussing or have blurred vision when taking Affenid. If these happen it may be dangerous to do things such as drive, use machines, ride a bike or horse or climb trees.
This medicine can affect your ability to drive. Do not drive whilst taking this medicine until you know how this medicine affects you. It may be an offence to drive if your ability to drive safely is affected.

Always take this medicine exactly as your doctor has told you.
Check with your doctor or pharmacist if you are not sure.
Your doctor will usually start treatment with a low dose and increase the daily dose by 18 mg no sooner than once a week if necessary.
The aim should be the lowest dose that is effective for you. Your doctor will decide the maximum daily dose for you or your child.
You should take Affenid once each day in the morning with a glass of water.
The tablet should be swallowed whole and not chewed, broken, or crushed. The tablet may be taken with or without food.
The tablet does not dissolve completely after all of the drug has been released and sometimes the tablet shell may appear in your stools. This is normal.
- the recommended starting dose of Affenid is 18 mg once daily for children who are not currently taking methylphenidate, or for children who are switching from another stimulant to methylphenidate.
- the maximum daily dose is 54 mg.
For adults who have taken Affenid before:
- if you have already taken Affenid as a child or adolescent, the same daily dosage (mg/day) can be used; your doctor will check regularly to see if any adjustment is required.
- adult patients may require a higher daily dosage but the doctor will aim to give you the lowest dose that is effective.
For adults who have not taken Affenid before:
- the recommended starting dose is 18 mg daily.
- The maximum daily dose in adults is 72 mg.
If you do not feel better after 1 month of treatment, tell your doctor.
Your doctor may decide you need a different treatment.
If Affenid is not used properly, this may cause abnormal behaviour.
It may also mean that you start to depend on the medicine.
Tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.
This medicine is only for you. Do not give this medicine to anyone else, even if their symptoms seem similar.
If you take too much medicine, talk to a doctor or call an ambulance straight away. Tell them how much has been taken.
Medical treatment might be needed.
Signs of overdose may include: being sick, feeling agitated, shaking, increased uncontrolled movements, muscle twitching, fits (may be followed by coma), feeling very happy, being confused, seeing, feeling or hearing things that are not real (hallucinations), sweating, flushing, headache, high fever, changes in heart beat (slow, fast or uneven), high blood pressure, dilated pupils and dry nose and mouth.
Do not take a double dose to make up for a forgotten dose. If you forget a dose, wait until it is time for the next dose.
If you suddenly stop taking this medicine, the ADHD symptoms may come back or unwanted effects such as depression may appear. Your doctor may want to gradually reduce the amount of medicine taken each day, before stopping it completely. Talk to your doctor before stopping Affenid.
Your doctor will do some tests
- before you start - to make sure that Affenid is safe and will be of benefit.
- after you start - they will be done at least every 6 months, but possibly more often. They will also be done when the dose is changed.
- these tests will include:
- checking your appetite
- measuring height and weight
- measuring blood pressure and heart rate
- checking whether you have any problems with your mood, state of mind or any other unusual feelings. Or if these have got worse while taking Affenid.
Affenid does not need to be taken for ever. If you take Affenid for more than a year, your doctor should stop treatment for a short time, this may happen during a school holiday. This will show if the medicine is still needed.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
