1. What is Medikinet and what is it used for

What is it used for

Medikinet is used to treat “attention deficit hyperactivity disorder” (ADHD).

• It is used in children from 6 years of age and in adults.
• It is used only after non-medication treatments, such as behavioral therapy and counseling, have been tried and proven to be insufficient.

Medikinet is not indicated for the treatment of ADHD in children under 6 years of age.

How it works

Medikinet improves the activity of certain parts of the brain that are underactive. The medicine may help improve attention and concentration and reduce impulsive behavior.

The medicine is given as part of a comprehensive treatment program, which usually includes psychological, educational, and social therapy.

Treatment with Medikinet should only be initiated by a doctor specializing in the treatment of ADHD, such as a pediatrician, child and adolescent psychiatrist, or psychiatrist, and should be used under their supervision. This doctor should perform a thorough medical examination. If you, as an adult, have not received this type of treatment before, the doctor will perform tests to confirm that you have had ADHD since childhood. Although ADHD has no cure, it can be controlled using comprehensive treatment programs.

About ADHD

Children and adolescents with ADHD have:

• difficulty staying still and
• difficulty concentrating.

It is not their fault that they cannot do these things.

Patient may present different degrees of ADHD with symptoms such as:

• lack of concentration
• restlessness
• hyperactivity
• impulsivity
• emotional instability
• disorganized thinking

Some of the external signs are:

• difficulty concentrating
• forgetfulness
• excessive use of words (logorrhea)
• difficulty planning and executing tasks to the end
• impulsive actions
• impatience

ADHD does not affect the child's or adolescent's intelligence.

2. What you need to know before you or your child take Medikinet

Do not take Medikinet if you or your child

• are allergic to methylphenidate or any of the other ingredients of this medicine (listed in section 6)
• have a thyroid problem
• have high eye pressure (glaucoma)
• have a tumor in the adrenal glands (pheochromocytoma)
• have an eating disorder, 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 had heart problems, such as a heart attack, irregular heartbeat, chest pain, heart failure, heart disease, or a heart problem at birth
• have had a problem with the blood vessels in the brain, such as a stroke, dilation or weakness of a blood vessel (aneurysm), narrowing or blockage of blood vessels, or inflammation of blood vessels (vasculitis)
• are taking or have taken in the last 14 days a medicine called a monoamine oxidase inhibitor (MAOI) for depression, see “Taking Medikinet with other medicines”
• have mental health problems, such as:

- a “psychopathic” or “borderline personality” disorder

• abnormal thoughts or visions or a disease called “schizophrenia”
• signs of a severe mood disorder, such as:
• suicidal thoughts
• severe depression, feeling very sad, worthless, and desperate
• mania, feeling exceptionally elated, more active than usual, and uninhibited.
• have a history of pronounced lack of stomach acid (low gastric acid) with pH values above 5.5
• are being treated with medicines to reduce stomach acid secretion or to treat excessive stomach acidity (H2 receptor blockers, proton pump inhibitors, or treatment with antacids).

Do not take methylphenidate if you or your child have any of the above. If you are not sure, consult your doctor or pharmacist before you or your child take methylphenidate. This is because methylphenidate may worsen these problems.

Warnings and precautions

Consult your doctor before you or your child start taking Medikinet if

• you or your child have liver or kidney problems
• you or your child have swallowing problems or difficulty swallowing whole tablets
• you or your child have had seizures (fits, convulsions, epilepsy) or any changes in the electroencephalogram (EEG, a brain study)
• you or your child have ever abused or been dependent on alcohol, prescription medicines, or illegal drugs
• you are a woman and have started your period (see below the section on “Pregnancy and breastfeeding”)
• you or your child have difficulty controlling repetitive movements of some parts of the body or repeat sounds and words (tics)
• you or your child have high blood pressure
• you or your child have a heart problem not listed in the previous “Do not take” section
• you or your child have a mental health problem not listed in the previous “Do not take” section. Other mental health problems include:

• mood changes (from manic to depressive, also known as “bipolar disorder”)

• seeing, hearing, or feeling things that are not there (hallucinations)
• believing things that are not real (delusions)

• feeling agitated, anxious, or tense
• feeling depressed or guilty.

Tell your doctor or pharmacist if you or your child have any of the above before starting treatment. Methylphenidate may worsen these problems. Your doctor will want to monitor how the medicine affects you or your child.

During treatment, children and adolescents may unexpectedly experience prolonged erections. Erections can be painful and occur at any time. It is essential to contact the doctor immediately if the erection lasts more than 2 hours, especially if it is painful.

Checks that your doctor will make before you or your child start treatment with methylphenidate

To decide if methylphenidate is the right medicine for you or your child, your doctor will check the following with you:

• the medicines you or your child are taking
• if you or your child have a family history of sudden unexplained death
• other diseases that you or your family (such as heart problems) may have
• how you or your child are feeling; for example, if you or your child have mood swings, have had strange thoughts, or have had feelings like this in the past
• if there have been cases of tics in your family (difficulty controlling repetitive movements of some parts of the body or repeated sounds and words)
• possible behavioral or mental health problems that you or your child or other family members have had.

Your doctor will explain specifically if you or your child are at risk of mood changes (from manic to depressive, also known as bipolar disorder). Your doctor will also check your or your child's mental health history and check if any family members have a history of suicide, bipolar disorder, or depression.

It is essential that you provide all the information you can. This will help your doctor decide if methylphenidate is the right medicine for you or your child. Your doctor may decide that you or your child need other medical tests before starting to take this medicine. For adult patients starting Medikinet, your doctor may refer you to a heart specialist.

Drug tests

This medicine may give a positive result in drug tests.

Athletes should be aware that this medicine may produce a positive result in doping tests.

Taking Medikinet with other medicines

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) for depression or have taken an MAOI in the last 14 days. Taking an MAOI with methylphenidate can cause a sudden increase in blood pressure.

If you or your child are taking other medicines, methylphenidate may affect how they work or cause side effects. Tell your doctor if you or your child are taking medicines for:

• depression
• mental health problems
• epilepsy
• blood pressure problems
• coughs and colds. Some remedies contain medicines that can affect blood pressure, so it is essential to consult your pharmacist when buying a product of this type
• medicines that thin the blood to prevent clot formation.

Medikinet should not be taken with H2 receptor blockers, proton pump inhibitors, or antacids (medicines to reduce stomach acid secretion or to treat excessive stomach acidity), as they may cause faster release of the total amount of active substance.

If you are unsure if any of the medicines you or your child are taking are included in the list above, consult your doctor or pharmacist for advice before taking methylphenidate.

Before an operation

Tell your doctor if you or your child are going to have an operation. You should not take methylphenidate on the day of the operation with certain types of anesthetics, as it may cause a sudden increase in blood pressure during the procedure.

• are having sex. Your doctor will discuss contraception with you.
• are pregnant or think you may be pregnant. Your doctor will decide if you should take methylphenidate.
