Treatment must be initiated under the supervision of a specialist in childhood and/or adolescent behavioural disorders. Pre-treatment screening Prior to prescribing, it is necessary to conduct a baseline evaluation of a patient’s cardiovascular status including blood pressure and heart rate.
4). 4). Blood pressure and pulse should be recorded on a centile chart at each adjustment of dose and then at least every 6 months; Height, weight and appetite should be recorded at least 6 monthly with maintenance of a growth chart; Development of de novo or worsening of pre-existing psychiatric disorders should be monitored at every adjustment of dose and then at least every 6 months and at every visit.
Patients should be monitored for the risk of diversion, misuse and abuse of methylphenidate. Dose titration Careful dose titration is necessary at the start of treatment with methylphenidate. Dose titration should be started at the lowest possible dose.
Other strengths of this medicinal product and other methylphenidate-containing products may be available. The maximum daily dosage of methylphenidate is 60 mg. g. at breakfast and lunch). Increase the dose and/or frequency of administration as necessary, by weekly increments of 5-10mg in the daily dose.
Long-term (more than 12 months) use in children and adolescents The safety and efficacy of long-term use of methylphenidate has not been systematically evaluated in controlled trials. Methylphenidate treatment should not and need not, be indefinite.
Methylphenidate treatment is usually discontinued during or after puberty. The physician who elects to use methylphenidate for extended periods (over 12 months) in children and adolescents with ADHD should periodically re-evaluate the long-term usefulness of the drug for the individual patient with trial periods off medication to assess the patient’s functioning without pharmacotherapy.
It is recommended that methylphenidate is dechallenged at least once yearly to assess child’s condition (preferably during times of school holidays). Improvement may be sustained when the drug is either temporarily or permanently discontinued.
Dose reduction and discontinuation Treatment must be stopped if the symptoms do not improve after appropriate dosage adjustment over a one-month period. If paradoxical aggravation of symptoms or other serious adverse events occur, the dosage should be reduced or discontinued.

Frequency estimate: - very common (≥ 1/10) - common (≥ 1/100 to < 1/10) - uncommon (≥ 1/1000 to < 1/100) - rare (≥ 1/10,000 to <1/1000) - very rare (<1/10,000) - not known (cannot be estimated from the available data).

Methylphenidate treatment is not indicated in all children with ADHD and the decision to use the drug must be based on a very thorough assessment of the severity and chronicity of the child’s symptoms in relation to the child’s age.
Long-term use (more than 12 months) in children and adolescents The safety and efficacy of long-term use of methylphenidate has not been systematically evaluated in controlled trials. Methylphenidate treatment should not and need not, be indefinite.
Methylphenidate treatment is usually discontinued during or after puberty. e. 4 for cardiovascular status, growth, appetite, development of de novo or worsening of pre- existing psychiatric disorders. Psychiatric disorders to monitor for are described below, and include (but are not limited to) motor or vocal tics, aggressive or hostile behaviour, agitation, anxiety, depression, psychosis, mania, delusions, irritability, lack of spontaneity, withdrawal and excessive perseveration.

Use in adults Methylphenidate is not licensed for use in adults with ADHD. Safety and efficacy have not been established in this age group. Use in the elderly Methylphenidate should not be used in the elderly. Safety and efficacy have not been established in this age group.
Use in children under 6 years of age Methylphenidate should not be used in children under the age of 6 years. Safety and efficacy in this age group has not been established. Cardiovascular status Patients who are being considered for treatment with stimulant medications should have a careful history (including assessment for a family history of sudden cardiac or unexplained death or malignant arrhythmia) and physical exam to assess for the presence of cardiac disease and should receive further specialist cardiac evaluation if initial findings suggest such history or disease.

Patients who develop symptoms such as palpitations, exertional chest pain, unexplained syncope, dyspnoea or other symptoms suggestive of cardiac disease during methylphenidate treatment should undergo a prompt specialist cardiac evaluation.
Analyses of data from clinical trials of methylphenidate in children and adolescents with ADHD showed that patients using methylphenidate may commonly experience changes in diastolic and systolic blood pressure of over 10 mmHg relative to controls.
The short- and long-term clinical consequences of these cardiovascular effects in children and adolescents are not known, but the possibility of clinical complications cannot be excluded as a result of the effects observed in the clinical trial data.
Caution is indicated in treating patients whose underlying medical conditions might be compromised by increases in blood pressure or heart rate. 3 for conditions in which methylphenidate treatment in contraindicated. Cardiovascular status should be carefully monitored.
Blood pressure and pulse should be recorded on a centile chart at each adjustment of dose and then at least every 6 months. 3). Sudden death and pre-existing cardiac structural abnormalities or other serious cardiac disorders Sudden death has been reported in association with the use of stimulants of the central nervous system at usual doses in children, some of whom had cardiac structural abnormalities or other serious heart problems.
Although some serious heart problems alone may carry an increased risk of sudden death, stimulant products are not recommended in children or adolescents with known cardiac structural abnormalities, cardiomyopathy, serious heart rhythm abnormalities, or other serious cardiac problems that may place them at increased vulnerability to the sympathomimetic effects of a stimulant medicine.
Misuse and Cardiovascular Events Misuse of stimulants of the central nervous system may be associated with sudden death and other serious cardiovascular adverse events. 3 for cerebrovascular conditions in which methylphenidate treatment is contraindicated.
Patients with additional risk factors (such as a history of cardiovascular disease, concomitant medications that elevate blood pressure) should be assessed at every visit for neurological signs and symptoms after initiating treatment with methylphenidate.
Cerebral vasculitis appears to be a very rare idiosyncratic reaction to methylphenidate exposure. There is little evidence to suggest that patients at higher risk can be identified and the initial onset of symptoms may be the first indication of an underlying clinical problem.
Early diagnosis, based on a high index of suspicion, may allow the prompt withdrawal of methylphenidate and early treatment. The diagnosis should therefore be considered in any patient who develops new neurological symptoms that are consistent with cerebral ischemia during methylphenidate therapy.
These symptoms could include severe headache, numbness, weakness, paralysis, and impairment of coordination, vision, speech, language or memory. Treatment with methylphenidate is not contraindicated in patients with hemiplegic cerebral palsy.
