1. What is Doprilten and what is it used for

What it is used for

Doprilten is used to treat "Attention Deficit Hyperactivity Disorder" (ADHD).

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

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

How it works

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

The medication is given as part of a comprehensive treatment program, which usually includes:

  • psychological therapy
  • educational therapy and
  • social therapy.

It is only prescribed by doctors who have experience in behavioral problems in children, adolescents, or adults. If you are an adult and have not received treatment before, the specialist 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
  • focusing

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 in daily life. Children and adolescents with ADHD may have difficulty learning and doing homework. They have difficulty behaving well at home, at school, and in other places.

Adults with ADHD often have difficulty concentrating. They often feel restless, impatient, and distracted. They may have difficulty organizing their private life and work.

Not all patients with ADHD need treatment with medication.

ADHD does not affect intelligence.

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

Do not take Doprilten if you or your child:

  • are allergic to methylphenidate or any of the other ingredients of this medicine (see section 6)
  • have a thyroid problem
  • have high eye pressure (glaucoma)
  • have a tumor in the adrenal glands (pheochromocytoma)
  • have an eating disorder, loss of appetite, or do not want to eat, such as in "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, widening or weakening of part of a blood vessel (aneurysm), narrowing or blockage of the blood vessels, or inflammation of the blood vessels (vasculitis)
  • are taking or have taken in the last 14 days a certain type of antidepressant (known as a monoamine oxidase inhibitor), see "Other medicines and Doprilten"
  • 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 excited, more active than usual, and uninhibited.

Do not take methylphenidate if you or your child have any of the above. If you are not sure, tell your doctor or pharmacist before you or your child take methylphenidate. This is because methylphenidate can make these problems worse.

Warnings and precautions

Tell your doctor before you or your child start taking Doprilten if you or your child:

  • have liver or kidney problems
  • have problems swallowing or swallowing whole tablets
  • have had seizures (fits, convulsions, epilepsy) or any alteration in the electroencephalogram (EEG)
  • have abused or been dependent on alcohol, prescription drugs, or drugs
  • are female and have started your period (see below the section on "Pregnancy and breastfeeding")
  • have difficulty controlling repetitive movements of some parts of the body or repeat sounds and words
  • have high blood pressure
  • have a heart problem not included in the previous "Do not take" section
  • have a mental health problem not included in the previous "Do not take" section.

Other mental health problems include:

  • mood changes (from being manic to being depressed, known as "bipolar disorder")
  • feeling aggressive or hostile
  • seeing, hearing, or feeling things that are not there (hallucinations)
  • believing things that are not real (delusions)
  • feeling strangely suspicious (paranoia)
  • 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. This is because methylphenidate can make these problems worse. Your doctor will want to monitor how the medication affects you or your child.

During treatment, male patients may experience unexpected prolonged erections. The 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 that your doctor will make before you or your child start taking Doprilten

To decide if methylphenidate is the right medicine for you or your child, your doctor will talk to you about:

  • any medicine that you or your child are taking
  • if you or your child have a family history of sudden unexplained death
  • other illnesses that you or your family (such as heart problems) may have
  • how you or your child are feeling, 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 being manic to being depressed, known as bipolar disorder). He 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 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 adults who start taking Doprilten, your doctor may refer you to a cardiologist.

Other medicines and Doprilten

Tell your doctor 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 "monoamine oxidase inhibitor" (MAOI) that is used 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 (see "Do not take Doprilten").

Tell your doctor or pharmacist if you or your child are taking any of the following medicines for depression or anxiety:

  • tricyclic antidepressant
  • selective serotonin reuptake inhibitor (SSRI)
  • serotonin and noradrenaline reuptake inhibitor (SNRI)

Taking methylphenidate with these types of medicines can cause a potentially life-threatening increase in "serotonin" in the brain (serotonin syndrome), which can cause confusion or restlessness, sweating, shivering, muscle spasms, or rapid heartbeat. If you or your child experience these side effects, see a doctor immediately.

If you or your child are taking other medicines, methylphenidate can affect how they work or cause side effects. If you or your child are taking any of the following medicines, talk to your doctor or pharmacist before taking methylphenidate:

  • medicines for severe mental health problems
  • medicines for Parkinson's disease (such as levodopa)
  • medicines for epilepsy
  • medicines used to lower or increase blood pressure
  • certain cough and cold remedies that contain medicines that can affect blood pressure. It is essential to talk to your pharmacist when you buy any of these medicines
  • medicines that thin the blood to prevent blood clots.

If you are unsure if any of the medicines you or your child are taking are included in the list above, talk to 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 can cause a sudden increase in blood pressure during the procedure.

Drug tests

This medicine can give a positive result in drug tests, even in tests used in sports.

Doprilten with alcohol

Do not drink alcohol while taking this medicine. Alcohol can make the side effects of this medicine worse. Remember that some foods and medicines contain alcohol.

Pregnancy, breastfeeding, and contraception

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, talk to your doctor before using this medicine.

The available data do not suggest an increased risk of total congenital anomalies, although a small increase in the risk of cardiac malformations during use in the first three months of pregnancy could not be ruled out. Your doctor will give you more information about this risk.

Talk to your doctor or pharmacist before using methylphenidate if you or your daughter:

  • are having sex. Your doctor will talk to you about contraception
  • are pregnant or think you may be pregnant. Your doctor will decide if you should use methylphenidate
  • are breastfeeding or plan to breastfeed. Methylphenidate passes into breast milk. Your doctor will decide if you or your daughter should breastfeed while using methylphenidate.

Driving and using machines

You or your child may feel dizzy, have problems focusing, or have blurred vision when taking methylphenidate. If this happens, it can be dangerous to do certain activities such as driving, operating machinery, riding a bike or horse, or climbing trees.

This medicine can affect your ability to drive.
