|methylphenidate extended release|
|How does this medication work? What will it do for me?|
Methylphenidate extended 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, adolescents, and adults who have been diagnosed with ADHD.
Other measures (e.g., psychological, educational, and social therapies) are used along with methylphenidate extended release as part of an overall treatment program for ADHD.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
|How should I use this medication?|
The dose of methylphenidate extended release needs to be indvidualized according to the needs of the person taking the medication. The dose is usually started low and increased gradually to the dose that works best for the person.
For people who are not currently taking methylphenidate extended release, the usual starting dose is 18 mg once daily in the morning with or without food.
For people currently taking methylphenidate extended release, the starting dose depends on the current dose being taken. Doses above 72 mg daily are not recommended.
Swallow this medication whole with water or other liquids. Do not crush, chew, or split the tablets. This medication is designed to be released into the body over time. When the tablet is broken, the medication is released into the body faster than it should be and may cause serious side effects.
You may notice the methylphenidate extended release tablet in your stool. If your child is on this medication, you may notice the tablet in your child's stool. This is normal and occurs because the tablet does not completely dissolve after all the medication has been released in the body.
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.

|Are there any other precautions or warnings for this medication?|
Before you begin taking 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 take this medication.
Behaviour or mood changes: There have been reports of agitation, hallucinations, symptoms of depression, and thoughts of self-harm 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.
Drowsiness/reduced alertness: Methylphenidate extended release may cause dizziness, 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 (not giving this medication during school holidays) might be appropriate for you or your child. Do not stop this medication without discussing it with your doctor first.
Exercise: If you participate in strenuous exercise or activities, consult your doctor before taking methylphenidate extended 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 extended 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.
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.
Stomach and intestinal problems: This medication should not be used by people with certain stomach or intestinal problems (e.g., narrowing of the intestines, "short gut" syndrome, a history of peritonitis, cystic fibrosis, chronic intestinal pseudo-obstruction, or Meckels' diverticulum).
Stopping the medication: Check with your doctor before stopping 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 methylphenidate extended release 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. Their doctor may also recommend a "drug holiday," where the medication is not given on weekends or during school holidays.
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,
Vision: Rarely, people taking methylphenidate extended 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 extended 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 children less than 6 years of age. Methylphenidate extended release should not be used by children in this age group.
