6. Contents of the pack and additional information

What it is used for

Rubifenis usedto treat “attention deficit hyperactivity disorder” (ADHD).

• It is used in children and adolescents aged 6 to 18 years.
• It is used only after having tried treatments that do not include medication, such as behavioral therapy and counseling.

Rubifen is not indicated for the treatment of ADHD in children under 6 years or in adults. Its safety or benefit in these patients is unknown.

How it works

Rubifen improves the activity of certain parts of the brain that have low activity. The medication may help improve attention (level of attention), concentration, and reduce impulsive behavior.

The medication is administered as part of an integrated treatment program, which typically includes:

• psychological therapy
• educational therapy and
• social therapy.

Only doctors with experience in children's or adolescents' behavioral problems can prescribe it. Although ADHD has no cure, it can be controlled using integrated 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.

Many children and adolescents struggle to do them. However, patients with ADHD may experience problems in daily life. Children and adolescents with ADHD may have difficulty learning and doing homework. They have difficulty behaving well at home, school, and other places.

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

Do not take Rubifen if you or your child:

• Are allergic to methylphenidate or any of the other components of this medication (listed in section 6)
• Have a thyroid problem
• Have high eye pressure (glaucoma)
• Have a tumor of the adrenal glands (pheochromocytoma)
• Have an eating disorder, are not hungry, or do not want to eat, such as in "anorexia nervosa"
• Have very high blood pressure or a narrowing of the blood vessels, which can cause pain in the arms and legs
• Have had any heart problems, such as a heart attack, irregular heartbeat, chest pain, heart failure, heart disease, or a congenital heart problem
• Have had any problems with the blood vessels in the brain, such as a stroke, dilation or weakness of a blood vessel (aneurysm), narrowing or blockage of the blood vessels, or inflammation of the blood vessels (vasculitis)
• Are taking or have taken an antidepressant (known as a monoamine oxidase inhibitor) in the last 14 days. See "Other medications and Rubifen"
• Have mental health problems, such as:
• • A "psychopathic" disorder or a "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, despised, and desperate
    • Mania, feeling exceptionally excited, more active than normal, and uninhibited

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

Warnings and precautions

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

Checks your doctor will make before you or your child start taking methylphenidateTo be able to decide if methylphenidate is the right medication for you or your child, your doctor will talk to you about:

• The medications you or your child are taking
• If you have a family history of sudden, unexplained death
• Other diseases you or your family (such as heart problems) may suffer from
• How you are, if you have mood swings, have abnormal thoughts, or if you have had feelings of this type in the past
• If there have been cases of tics in your family (difficulty controlling repetitive movements of some parts of the body or sounds and words)
• Possible behavior or mental health problems you or your child have had at any time. Your doctor will explain specifically if you or your child are at risk of developing mood swings (from being manic to being depressed, known as bipolar disorder). Your doctor will 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 to provide all the information you can. This will help your doctor decide if methylphenidate is the right medication for you or your child. It is possible that your doctor will decide that you or your child need other medical tests before starting to take this medication.

Other medications and Rubifen
