1. What Symkinet MR is and what it is used for
What Symkinet MR is used for
Symkinet MR is used to treat Attention Deficit Hyperactivity Disorder (ADHD).
- It is used in children and adolescents aged 6 to 18 years, as well as in adult patients.
- It is used only when previous non-pharmacological treatment attempts, such as psychological counselling and behavioural therapy, have been insufficient. Symkinet MR is not used to treat ADHD in children under 6 years of age. It is not known whether the medicine is safe or effective in children under 6 years of age.
How Symkinet MR works
Symkinet MR improves the function of certain parts of the brain that are less active. The medicine may help improve attention, concentration, and reduce impulsive behaviours.
Symkinet MR is used as part of a treatment programme that usually includes:
- psychological therapy;
- educational therapy;
- social interventions.
Treatment with Symkinet MR must be initiated and continued only by a doctor specialised in the treatment of ADHD, such as a paediatric specialist, child and adolescent psychiatrist, or psychiatrist. A thorough evaluation by such a doctor is required. If the patient is an adult who has not been previously treated, the doctor will carry out assessments to confirm that ADHD has been present since childhood. Therapeutic programmes and medication help control ADHD.
About ADHD
Children and adolescents with ADHD have difficulties:
- sitting still without moving;
- concentrating.
This behaviour is not their fault, as they cannot control it.
Many children and young people experience such problems. However, individuals with ADHD may face difficulties in everyday life. Children and adolescents with ADHD may have problems with learning and completing homework.
Adults with ADHD often have concentration difficulties. They often feel restless, impatient, and inattentive. They may have problems organising their personal and professional lives.
Not all patients with ADHD require pharmacological treatment. The decision to start treatment in children must be based on a thorough assessment determining the severity and chronic nature of the child's symptoms.
ADHD does not affect intelligence.
2. Important information before using Symkinet MR

- if the patient has thyroid dysfunction;
- if the patient has increased intraocular pressure (glaucoma);
- if the patient has a tumour of the adrenal gland called phaeochromocytoma;
- if the patient is currently taking antidepressant medicines known as monoamine oxidase inhibitors (MAOIs), or has taken such medicines within the last 14 days (see section "Symkinet MR and other medicines");
- if the patient has eating disorders; lack of appetite or desire to eat (e.g. anorexia nervosa);
- if the patient has very high blood pressure or peripheral vascular constriction which may cause pain in hands and feet;
- if the patient has ever had heart problems such as: heart attack, irregular heartbeat, chest pain or discomfort, heart failure, heart disease or congenital heart defects;
- if the patient has had cerebrovascular disorders such as: stroke, localized enlargement and weakening of a blood vessel wall (aneurysm), narrowing or blockage of blood vessels, or inflammation of blood vessels;
- if the patient has psychiatric disorders such as:
- psychopathic disorders or borderline personality;
- delusions or hallucinations, or a condition called schizophrenia;
- symptoms of severe mood disorders such as:
- suicidal thoughts;
- severe depression (when the patient feels very sad, worthless, and hopeless about the future);
- mania (when the patient is extremely excited, overly active, and uncontrollable in their behaviour);
- mood swings from depression to mania.
Methylphenidate should not be used if any of the above conditions apply to the patient.
If in doubt, consult a doctor or pharmacist before using methylphenidate, as methylphenidate may worsen these conditions.
Warnings and precautions
Before starting treatment with Symkinet MR, discuss with a doctor or pharmacist if the patient:
- has liver or kidney dysfunction;
- has had seizures (epilepsy) or abnormal electroencephalogram (EEG) findings;
- has ever abused or been dependent on alcohol, prescription medicines, or illicit drugs;
- is a woman or girl who has started menstruation (see section below "Pregnancy, breastfeeding and fertility");
- or a family member has uncontrollable, repetitive movements or repeats sounds and words (motor or verbal tics);
- has high blood pressure;
- has heart diseases other than those listed above under "When not to use Symkinet MR";
- has psychiatric disorders not listed under "When not to use Symkinet MR". Other psychiatric disorders include:
- mood swings (from mania to depression, known as bipolar affective disorder);
- emergence of aggressive or hostile behaviours, or increased aggression;
- seeing, hearing, or feeling things that are not real (hallucinations);
- believing in things that are not true (delusions);
- excessive suspiciousness (paranoia);
- feelings of restlessness, anxiety, or tension;
- feelings of depression or guilt.
Before starting treatment, inform the doctor or pharmacist if any of the above conditions apply to the patient. Methylphenidate may worsen these conditions. The doctor will monitor how the medicine affects the patient.
During treatment, boys and men may experience unexpected prolonged erections.
This may be painful and can occur at any time. If an erection lasts longer than 2 hours, especially if it is painful, contact a doctor immediately.
Medical interview before using methylphenidate
This interview helps determine whether methylphenidate is an appropriate medicine for the patient. The doctor will discuss with the patient:
- any other medicines the patient is taking;
- any family history of sudden unexplained death;
- any other medical problems (e.g. heart conditions) affecting the patient or their family;
- the patient’s or child’s emotional state, such as depression or euphoria, unusual thoughts, or whether such feelings occurred in the past;
- presence of tics (uncontrollable, repetitive movements of body parts or repetition of sounds or words) in the patient’s family;
- any psychiatric or behavioural disorders in the patient or their family. The doctor will discuss the risk of mood swings (from mania to depression – known as bipolar affective disorder). The doctor will also take a psychiatric history and determine whether there have been cases of suicide, bipolar affective disorder, or depression in the patient’s family.
It is important to provide the doctor with as much information as possible. Based on this, the doctor will decide whether methylphenidate is suitable for the patient. The doctor may also decide whether additional medical tests are required before starting treatment with this medicine.
Drug screening tests
This medicine may cause a positive result in drug screening tests.
Misuse as a performance-enhancing agent
Use of Symkinet MR may lead to positive results in anti-doping tests.
Improper use of Symkinet MR as a performance-enhancing agent may pose a health risk.
Symkinet MR and other medicines
Tell the doctor or pharmacist about all medicines currently or recently taken by the patient or child, as well as any medicines the patient plans to take.
Do not use methylphenidate if the patient or child:
- is taking or has taken within the last 14 days a medicine known as a monoamine oxidase inhibitor (MAOI) used to treat depression. Concurrent use of MAOIs and methylphenidate may cause a sudden increase in blood pressure (see section "When not to use Symkinet MR").
If the patient or child is taking other medicines, methylphenidate may affect their action or cause adverse effects. It may be necessary to reduce the dose or discontinue concomitant treatment. Before taking methylphenidate, inform the doctor or pharmacist if the patient is taking any of the following medicines:
- medicines used to treat depression;
- medicines used to treat serious psychiatric disorders (e.g. schizophrenia);
- antiepileptic medicines;
- medicines used to lower or raise blood pressure;
- some cough and cold medicines containing ingredients that affect blood pressure. Ask the pharmacist when purchasing such medicines;
- blood-thinning medicines that prevent blood clots.
If in doubt whether a medicine taken by the patient is on the above list, consult a doctor or pharmacist before using methylphenidate.
Surgical procedures
Inform the doctor about any planned surgery. Do not take methylphenidate on the day of surgery if certain types of anaesthetic agents are to be used, due to the risk of sudden increase in blood pressure during the operation.
Symkinet MR with food, drink and alcohol
Do not consume alcohol while taking this medicine. Alcohol may worsen the adverse effects of this medicine. Note that some food products and medicines contain alcohol.
Pregnancy, breastfeeding and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult a doctor before using this medicine.
Available data do not indicate an increased overall risk of congenital malformations, although a small increased risk of cardiac developmental defects cannot be ruled out during use of the medicine in the first three months of pregnancy. The doctor can provide the patient with additional information about this risk.
Before using methylphenidate, inform the doctor or pharmacist if the patient:
- is sexually active. The doctor will discuss methods of contraception.
- is pregnant or suspects she may be pregnant. The doctor will decide whether methylphenidate should be used.
- is breastfeeding or planning to breastfeed. Methylphenidate passes into human milk. Therefore, the doctor will decide whether breastfeeding should continue during treatment with methylphenidate.
Driving and operating machinery
While taking methylphenidate, dizziness, drowsiness, difficulty focusing vision, blurred vision, hallucinations, or other adverse effects on the central nervous system may occur. If such symptoms occur, activities such as driving vehicles, operating machinery, cycling, horse riding, or climbing trees may be dangerous.
Symkinet MR contains sucrose
Symkinet MR contains sucrose (a type of sugar). If the patient has been previously diagnosed with an intolerance to certain sugars, the patient should consult a doctor before taking this medicine.
3. How to take Symkinet MR
This medicine should always be taken exactly as your doctor has instructed. If in doubt, consult your doctor or pharmacist.
Dosage
Your doctor will usually start treatment with a low dose and increase it gradually if necessary.
Children (6 years of age and older) and adolescents
The recommended starting dose is 20 mg once daily. Your doctor may also decide to start treatment with a dose of 10 mg. The maximum daily dose is 60 mg. In patients under 18 years of age, Symkinet MR should be taken once daily in the morning.
Adult patients
- For patients who are taking Symkinet MR for the first time, your doctor will start treatment with a daily dose of 20 mg, and if necessary, will gradually increase the dose, typically once a week.
- If a patient has previously taken methylphenidate in a modified-release formulation as a child or adolescent and has recently turned 18 years old, your doctor may continue the same daily dose. If the patient was previously treated with an immediate-release formulation as a child or adolescent, your doctor will prescribe an appropriate dose of Symkinet MR.
The maximum daily dose is 80 mg.
Lower doses of this medicine or other medicines containing methylphenidate are available.
Procedures your doctor will perform before and during treatment (for both adult and child patients)
Your doctor will carry out certain assessments:
- Before starting treatment – to ensure that Symkinet MR is safe and beneficial for the patient (as described in the section “Medical history before using methylphenidate”);
- After starting treatment – at least once every 6 months, but possibly more frequently, and also with any dose adjustment. Assessments will include:
- Checking appetite;
- Measuring height and body weight in children;
- Measuring body weight in adult patients;
- Measuring blood pressure and pulse;
- Evaluating mood, mental status, or any other abnormalities, and whether they have worsened during treatment with Symkinet MR.
Method of administration
Symkinet MR is for oral use.
Symkinet MR should be taken once daily in the morning. Do not take the medicine too late in the day, as it may cause sleep disturbances.
- Capsules may be taken with or without food.
- Capsules should be swallowed whole with a glass of water.
- Capsules or their contents must not be crushed, chewed, or divided.
If a patient or child is unable to swallow the Symkinet MR capsule, the capsule contents may be mixed with a small amount of food as follows:
- Carefully open the capsule and sprinkle the contents onto a small amount of soft food (e.g. applesauce).
- The food must not be hot, as this may affect the special properties of the pellets.
- The medicine mixed with food should be taken immediately. Do not store the mixture for later use.
Instructions for opening the blister pack
The medicine is supplied in child-resistant blister packs. The following instructions describe how to open the blister.
- Do not push the capsule through the blister, as this may damage the capsule.
- Hold the blister with the printed foil side up. Bend the blister backward along the perforated line, then bend it in the opposite direction. Repeat this several times. Then tear the blister along the perforation to separate a single dose.
- To remove the capsule, gently peel back the protective foil starting from the corner indicated by the arrow, and then lift it off.
Long-term treatment
There is no need to take Symkinet MR indefinitely. If a patient has been taking Symkinet MR for more than one year, the doctor should interrupt treatment for a short period once a year. In children, this may occur during school holidays. This allows assessment of whether continued treatment is still necessary.
If the patient’s condition has not improved after 1 month of treatment
If the patient’s condition has not improved after 1 month of treatment, inform the doctor. The doctor may decide to change the treatment approach.
Misuse of Symkinet MR
Misuse of Symkinet MR may lead to unusual behaviors and may also result in dependence on the medicine. If the patient has ever abused or been dependent on alcohol, prescription medicines, or illicit drugs, this should be reported to the doctor. This medicine is intended only for the person to whom it was prescribed. Do not give it to others, even if their symptoms appear similar.
Taking more than the recommended dose of Symkinet MR
If a patient takes too much medicine, contact a doctor or call emergency services immediately. Inform them of the amount of medicine taken. Treatment may be necessary.
Symptoms of overdose may include: vomiting, feeling overstimulated, tremors, increased involuntary movements, muscle twitching, seizures (possibly followed by coma), feelings of euphoria, disorientation, seeing, feeling, or hearing things that are not real (hallucinations), sweating, facial flushing, headache, high fever, changes in heart rhythm (slow, fast, or irregular), high blood pressure, dilated pupils, dryness of the nasal mucosa and oral cavity, muscle swelling, weakness, tenderness, and muscle pain, and dark-colored urine.
Missed dose of Symkinet MR
Do not take a double dose to make up for a missed dose. If a dose is missed, take the next dose at the usual time.
Stopping Symkinet MR
Stopping this medicine suddenly may lead to a return of ADHD symptoms or the appearance of unexpected symptoms such as depression. Before completely discontinuing the medicine, your doctor will gradually reduce the daily dose. Consult your doctor before stopping treatment with Symkinet MR.
If you have any further questions about the use of this medicine, consult your doctor or pharmacist.
