methylphenidate controlled release
How does this medication work? What will it do for me?
Methylphenidate controlled release belongs to the family of medications known as stimulants. It is used to treat attention deficit hyperactivity disorder (ADHD). It helps to increase attention and decrease restlessness in children 6 years of age and older, adolescents, and adults who have been diagnosed with ADHD.
Other measures (e.g., psychological, educational, and social therapies) are used along with methylphenidate controlled release as part of an overall treatment program for ADHD.

How should I use this medication?
The dose of methylphenidate controlled release is determined according to the needs of the person taking the medication. The dose is usually started low and increased gradually at weekly intervals.
For people who are not already taking methylphenidate, the usual starting dose is 10 – 20 mg once daily in the morning, at breakfast.
For people already taking methylphenidate controlled release, the starting dose depends on the dose being taken. The maximum dose is 60 mg daily for children 6 years and older and 80 mg daily for adults.
Swallow this medication whole with water or other liquids. Do not crush or chew the capsules. This medication is designed to be released into the body over time. When the contents of the capsule are crushed, the medication is released into the body faster than it should be and may cause serious side effects.
If desired, the capsule may be opened and the contents of the capsule (the medication) may be sprinkled onto apple sauce, ice cream, or yogurt.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones above, do not change the way that you are taking the medication without consulting your doctor.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. Avoid taking this medication late in the day, as it may cause difficulty sleeping. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Store this medication at room temperature, protect it from moisture, and keep it out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Behaviour or mood changes: There have been reports of agitation, aggression, hallucinations, and symptoms of depression in people taking this medication. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately. You should be closely monitored by your doctor for emotional and behaviour changes while taking this medication.
Blood pressure: This medication can increase blood pressure. If you have high blood pressure, or heart problems, talk to your doctor before taking this medication.
Circulation Problems: Like other stimulant medications, methylphenidate controlled-release may cause problems with blood circulation, particularly to the fingers and toes. If you notice unusual episodes of cold fingers or toes, or develop sores that aren’t healing well, talk to your doctor.
Drowsiness/reduced alertness: Methylphenidate controlled release may cause dizziness or vision changes, which could affect your ability to drive or operate machinery. Avoid activities requiring alertness until you have determined how this medication affects you.
Drug dependence: There does not appear to be an increased risk of dependence or addiction with the use of methylphenidate by children and adolescents. However, abuse of methylphenidate is possible by certain individuals. Regular, long-term abuse can lead to high levels of tolerance and psychological dependence, and a wide range of abnormal behaviours. If you have a history of drug or alcohol dependence, you should be closely monitored by your doctor while using this medication.
Drug holidays: It is sometimes helpful to stop methylphenidate to determine whether it is still needed to help the ADHD symptoms. Talk to your doctor about whether a drug holiday might be appropriate for you or your child. Do not stop this medication without discussing it with your doctor first.
Exercise: People participating in strenuous exercise or activities should consult their doctor before taking methylphenidate controlled release. Strenuous exercise combined with the effects of methylphenidate of the heart and blood pressure may increase the risk of sudden death.
Heart problems and blood pressure: This medication can increase heart rate and blood pressure. It may also increase the risk of sudden death for people with heart problems. This medication should generally not be used by people with known structural heart abnormalities (such as abnormal size, missing or poorly functioning heart valves, or problems with blood vessels connected to the heart), or a family history of sudden or cardiac death. People taking more than one stimulant medication for ADHD should be closely monitored by their doctor.
Misuse of methylphenidate may also be associated with sudden death and other serious heart-related effects.
Long-term use: If you will be using methylphenidate controlled release for a long period of time, your doctor will want you to have regular heart checkups, blood pressure checks and lab tests to monitor your liver and blood.
Prolonged Erections: Rarely, prolonged and painful erections (called priapism) have been reported by patients using methylphenidate. Priapism is a very rare condition that can affect children as well as adults. It may occur after increasing the dose or stopping the medication for a short period of time.
Patients who develop priapism should seek immediate medical attention to prevent potential long-term effects on the penis.
Psychiatric Conditions: Methylphenidate may cause other mental health conditions to develop or become worse. Severe mood swings, unusual excitement, increased or new aggressive behavior, or other behavior changes may indicate changes in mental health. If you notice any change in thinking or behavior in yourself or family members, contact your doctor.
Seizures: There is some evidence that methylphenidate extended release may increase the risk of seizures, particularly for people who have had seizures in the past. If you have a history of epilepsy or medical conditions that increase the risk of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Stopping the medication: Check with your doctor before stopping this medication. Suddenly stopping the medication may cause mental conditions or hyperactivity to return.
Suicidal or agitated behaviour: People taking this medication may feel agitated (restless, anxious, aggressive, emotional, and feeling not like themselves), or they may want to hurt themselves or others. These symptoms may occur within several weeks after starting this medication. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately. You should be closely monitored by your doctor for emotional and behaviour changes while taking this medication.
Suppression of growth: Growth suppression (i.e., less increase in height or weight than usual) has been reported for children using stimulants such as methylphenidate for long periods of time. It is not known if this medication causes growth suppression in children (i.e., less increase in height or weight than usual). Children who need long-term treatment should be carefully monitored for growth.
Tics: This medication may cause tics or worsening of motor or verbal tics. If you have Tourette’s syndrome or develop tics while on this medication, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vision: Rarely, people taking methylphenidate controlled release have experienced vision changes. If you notice any changes in your vision, contact your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking methylphenidate controlled release, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of this medication have not been established for and should not be used by children less than 6 years of age.
