1. What Rubifen is and what it is used for

What it is used for

Rubifen is used to treat "attention deficit hyperactivity disorder" (ADHD).

• It is used in children and adolescents aged between 6 and 18 years.
• It is used only after non-medication treatments have been tried first, such as behavioral therapy and counseling.

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

How it works

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

The medicine is administered as part of a comprehensive treatment program, which usually includes:

• psychological therapy,
• educational therapy, and
• social therapy.

It is prescribed only by physicians experienced in managing behavioral problems in children or adolescents. Although ADHD cannot be cured, it can be managed through 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.

Many children and adolescents struggle with these tasks. However, patients with ADHD may experience problems in daily life. Children and adolescents with ADHD may have difficulties learning and completing homework. They may have trouble behaving appropriately at home, at school, and in other settings.

ADHD does not affect the intelligence of the child or adolescent.

2. What you need to know before you or your child start taking Rubifen

Do not take Rubifen if you or your child:

• Are allergic to methylphenidate or to any of the other ingredients of this medicine (listed in section 6)
• Have a thyroid problem
• Have high intraocular pressure (glaucoma)
• Have a tumor of the adrenal glands (pheochromocytoma)
• Have an eating disorder, lack of appetite, or refusal to eat, such as in "anorexia nervosa"
• Have very high blood pressure or narrowing of blood vessels, which may cause pain in the arms and legs
• Have ever had heart problems such as a heart attack, irregular heartbeat, chest pain or discomfort, heart failure, heart disease, or a congenital heart condition
• Have ever had a blood vessel problem in the brain such as stroke, dilation or weakness of part of a blood vessel (aneurysm), narrowing or blockage of blood vessels, or inflammation of blood vessels (vasculitis)
• Are currently taking or have taken within the last 14 days any antidepressant medication (known as a monoamine oxidase inhibitor). See "Other medicines and Rubifen"
• Have mental health problems such as:
  • A "psychopathic" disorder or "borderline personality disorder"
  • Abnormal thoughts or hallucinations or a condition called "schizophrenia"
  • Signs of a severe mood disorder such as:
    • Suicidal thoughts
    • Severe depression, feeling very sad, worthless, and hopeless
    • Mania, feeling unusually elated, more active than normal, and disinhibited

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

Warnings and precautions

Talk to your doctor before starting Rubifen if you or your child:

• Have liver or kidney problems
• Have difficulty swallowing or problems swallowing whole tablets
• Have narrowing or blockage in the digestive tract
• Have ever had seizures (fits, convulsions, epilepsy) or any abnormalities on an electroencephalogram (EEG, a test of brain activity)

• Have high blood pressure
• Have a heart condition not listed in the previous section "Do not take methylphenidate if you or your child"

  • Mood changes (from mania to depression, known as "bipolar disorder")
  • Experiencing aggressive or hostile behavior, or worsening aggression
  • Seeing, hearing, or feeling things that are not there (hallucinations)
  • Believing things that are not true (delusions)
  • Feeling unusually suspicious (paranoia)
  • Feeling restless, anxious, or tense

Inform your doctor or pharmacist if you or your child have any of the conditions listed above before starting treatment. This is because methylphenidate may worsen these conditions. Your doctor will want to monitor how the medicine affects you or your child.

During treatment, children and adolescents may unexpectedly experience prolonged erections. These erections may be painful and can occur at any time. It is important to contact a doctor immediately if an erection lasts longer than 2 hours, especially if it is painful.

If you or your child experience blurred vision or other visual disturbances, contact your doctor. Your doctor may consider stopping treatment with Rubifen.

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

To determine whether methylphenidate is the right medicine for you or your child, your doctor will discuss with you:

• The medicines you or your child are taking
• Whether there is a family history of unexplained sudden death
• Other illnesses you or your family may have (such as heart problems)
• How you are feeling, whether you have mood swings, strange thoughts, or have had such feelings in the past
• Whether there have been cases of tics in your family (difficulty controlling repetitive movements of certain body parts or repeated sounds and words)
• Any possible behavioral or mental health problems you or your child or other family members may have had. Your doctor will specifically explain whether you or your child are at risk of mood changes (from mania to depression, known as bipolar disorder). Your doctor will review your or your child's mental health history and check whether any family members have a history of suicide, bipolar disorder, or depression.

It is important to provide as much information as possible. This will help your doctor decide whether methylphenidate is the right medicine for you or your child. Your doctor may decide that you or your child need further medical tests before starting this medicine.

Other medicines and Rubifen

Tell your doctor or pharmacist if you or your child are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription.

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 within the last 14 days. Using an MAOI with methylphenidate may cause a sudden increase in blood pressure.

If you or your child are taking other medicines, methylphenidate may affect how these medicines work or cause adverse effects. If you or your child are taking any of the following medicines, consult your doctor or pharmacist before taking methylphenidate:

• Other medicines for depression
• Medicines for serious mental health conditions
• Medicines for epilepsy
• Medicines used to lower or raise blood pressure
• Some cough and cold remedies containing medicines that may affect blood pressure. It is important to consult your pharmacist when purchasing such medicines
• Medicines that thin the blood to prevent clots

If you have any doubts about whether 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 surgery

Inform your doctor if you or your child are scheduled for surgery. Methylphenidate should not be taken on the day of surgery when certain types of anesthetics are used, as this may cause a sudden increase in blood pressure during the procedure.

Drug testing

This medicine may give a positive result in drug tests, including those used in sports.

Taking Rubifen with food, drinks, and alcohol

Taking methylphenidate with food may help relieve stomach pain, nausea, or vomiting.

Do not drink alcohol while taking this medicine. Alcohol may worsen the adverse effects of this medicine. Remember that some foods and medicines contain alcohol.

Pregnancy and breastfeeding

Available data do not suggest an increased risk of overall congenital abnormalities, although a small increased risk of cardiac malformations during use in the first three months of pregnancy could not be ruled out. Your doctor will provide further information about this risk. Consult your doctor or pharmacist before using methylphenidate if you or your daughter:

• Are sexually active. Your doctor will discuss contraception with you
• Are pregnant or think you may be pregnant. Your doctor will decide whether you should use methylphenidate
• Are breastfeeding or plan to breastfeed. Methylphenidate may pass into human milk. Therefore, your doctor will decide whether you or your daughter should breastfeed while using methylphenidate.

Driving and using machines

You or your child may experience dizziness, difficulty focusing, or blurred vision when taking methylphenidate. If this occurs, it may be dangerous to carry out certain activities such as driving, operating machinery, riding a bicycle or horse, or climbing trees.

3. How to take Rubifen

How much to take

Follow exactly the instructions for use of this medicine given by your doctor. If in doubt, consult your doctor or pharmacist again.

Your doctor will usually start treatment with a low dose and gradually increase it as needed.

• The maximum daily dose is 60 milligrams.
• The tablet should be swallowed with a glass of water. It is recommended to take the tablets with food.

The score line is intended only for breaking the tablet if you have difficulty swallowing it whole, but not for dividing it into equal doses.

If you or your child do not feel better after 1 month of treatment

If you or your child do not feel better, inform your doctor. They may decide whether a different treatment is needed.

Inappropriate use of Rubifen

If Rubifen is not used appropriately, it may cause abnormal behavior. This may also mean that you or your child begin to become dependent on the medicine. Inform your doctor if you or your child have ever abused or been dependent on alcohol, prescription medicines, or drugs.

This medicine is for you or your child only. Do not give this medicine to anyone else, even if they have similar symptoms.

If you or your child take more Rubifen than you should

If you or your child take too many tablets, consult your doctor immediately or go to the nearest hospital emergency department and tell them how many tablets have been taken. You may also contact the Toxicology Information Service at telephone number 91 562 04 20.

Signs of overdose may include: nausea, agitation, tremors, increased uncontrolled movements, muscle twitching, seizures (which may be followed by coma), feeling extremely happy, confusion, seeing, feeling, or hearing things that are not real (hallucinations), sweating, flushing, headache, high fever, changes in heartbeat (slow, fast, or irregular), high blood pressure, dilated pupils, and dryness of the nose and mouth.

If you or your child forget to take Rubifen

Do not take a double dose to make up for missed doses. If you or your child forget a dose, wait and take the next dose at the scheduled time.

If you or your child stop taking Rubifen

If you or your child stop taking this medicine suddenly, ADHD symptoms may return or unwanted effects such as depression may occur. Your doctor may want to gradually reduce the amount of medicine taken each day before stopping completely. Consult your doctor before stopping treatment with Rubifen.

What your doctor will do while you or your child are on treatment

Your doctor will carry out some tests

• before you or your child start treatment, to ensure that Rubifen is safe and beneficial
• after treatment has started, at least every 6 months, and even more frequently
• also when the dose is changed
• these tests will include:
  • monitoring of appetite
  • measurement of height and weight
  • measurement of blood pressure and heart rate
  • assessment of mood-related problems, mental state, or any other unusual feelings, or whether these have worsened while taking Rubifen.

Long-term treatment

Rubifen does not need to be taken indefinitely. If you or your child take Rubifen for more than one year, your doctor should interrupt treatment for a short period, such as during school holidays. This allows assessment of whether the medicine is still needed.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
