Ambinet XL is used to treat ‘attention deficit hyperactivity disorder’ (ADHD).
Ambinet XL is not for use as a treatment for ADHD in children under 6 years of age.
Ambinet XL improves the activity of certain parts of the brain which are under-active. The medicine can help improve attention span and concentration, and reduce impulsive behaviour.
The medicine is given as part of a treatment programme, which usually includes
Ambinet 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 careful examination by this doctor is required. If you as an adult have not been treated before, the doctor will perform tests to confirm that you have been affected by ADHD since childhood. Although there is no cure for ADHD, it can be managed using treatment programmes.
Children and young people with ADHD find it:
It is not their fault they cannot do these things.
Patients can have ADHD in varying degrees with symptoms including:
This is shown by, for example:
ADHD does not affect the intelligence of a child or young person.
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 you or your child takes methylphenidate. This is because methylphenidate can make these problems worse.
Talk to your doctor before taking Ambinet 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. 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 Ambinet XL.
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.
Checks that your doctor will make before you start taking methylphenidate
These checks are to decide if methylphenidate is the correct medicine for you or your child. Your doctor will talk to you about:
Your doctor will discuss whether you or your child is at risk of having mood swings (from being manic to being depressed - called ‘bipolar disorder’). They will check you 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. For adult patients that are new to Ambinet XL, your doctor may refer you to a heart specialist.
Drug testing
This medicine may give a positive result when testing for drug use.
Athletes must be aware that this medicinal product may cause a positive reaction to ‘anti-doping’ tests.
Please tell your doctor or pharmacist if you or your child is taking, has recently taken or may take any other medicines.
If you or your child is taking other medicines, methylphenidate may affect how well they work or may cause side effects. Tell your doctor if you or your child is taking medicines to treat:
Ambinet XL must not be taken together with H2 receptor blockers, proton pump inhibitors or antacids which are used to reduce gastric acid secretion or to counteract excessive acidity in the stomach, as this could lead to a faster release of the total amount of active substance.
If you are in any doubt about whether any medicines you or your child is taking are included in the list above, ask your doctor or pharmacist for advice before taking methylphenidate.
Having an operation
Tell your doctor if you or your child is 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 during the operation.
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.
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 methylphenidate if you or your daughter:
You or your child may feel dizzy, feel drowsy, have problems focussing or have blurred vision, have hallucinations or other side effects in the central nervous system 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.
You or your child should always take Ambinet XL exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

Ambinet XL is a form of methylphenidate with “controlled release” action, which releases the drug gradually over a prolonged period of time. Taking the capsule with or after meals is very important in order for their action to be delayed.
The capsules may be swallowed whole with a drink of water. Alternatively, you can open the capsules, sprinkle the contents onto a small amount (tablespoon) of applesauce or yoghurt and take it immediately. Do not store for future use. The capsules and the capsule contents must not be crushed or chewed.
If you or your child does not feel better after 1 month of treatment
If you or your child does not feel better after 1 month of treatment, tell your doctor. Your doctor may decide that you or your child needs a different treatment.
Long-term treatment
Ambinet XL does not need to be taken for ever. If you or your child takes Ambinet XL for more than a year, your doctor should stop treatment at least once per year for a short time. In case of children this may happen during a school holiday. This will show if the medicine is still needed.
Not using Ambinet XL properly
If Ambinet XL is not used properly, this may cause abnormal behaviour. It may also mean that you or your child starts to depend on the medicine. Tell your doctor if you or your child has 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 or your child takes too much of the medicine, talk to a doctor or call an ambulance straight away. Tell them how much has been taken. You may need medical treatment.
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, muscle spasms, fever and reddish-brown urine which could be possible signs of abnormal breakdown of muscles (rhabdomyolysis).
Do not take a double dose to make up for a forgotten dose.
If you or your child forgets a dose, wait until it is time for the next dose.
If you or your child suddenly stops taking this medicine, 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 Ambinet XL.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
