Consumer Information
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for
1) When used in ADHD, APO-METHYLPHENIDATE improves
behaviour by reducing restlessness and increasing attention.
APO-METHYLPHENIDATE, however, will not cure ADHD.
Treatment with APO-METHYLPHENIDATE or other
stimulants should always be combined with other treatment
measures, such as psychological counseling and educational
tutoring by skilled and experienced therapists.
Children and/or adolescents treated with APOMETHYLPHENIDATE do not seem to become addicted or
abuse drugs later in life. However, central nervous stimulants,
including APO-METHYLPHENIDATE, should only be given
under close medical supervision to patients whose condition has
been properly diagnosed.
About ADHD
ADHD is a disorder characterized by symptoms of inattentiveness and/or hyperactivity-impulsivity inappropriate to the patient’s age, which interfere with functioning in two or more settings (e.g., school and home). Symptoms of inattention may include not paying attention, making careless mistakes, not listening, not finishing tasks, not following directions, and being easily distracted. Symptoms of hyperactivity-impulsiveness may include fidgeting, talking excessively, running around at inappropriate times, and interrupting others. Some patients have more symptoms of hyperactivity and impulsiveness while others have more symptoms of inattentiveness. Some patients have both types of symptoms. Symptoms must be present for at least 6 months to be certain of the diagnosis.
2) When used in narcolepsy, APO-METHYLPHENIDATE may relieve the inappropriate daytime sleepiness; however, many people suffering from narcolepsy need additional treatment aimed at other aspects of this condition.
About Narcolepsy
Persons who suffer from narcolepsy experience attacks of sleepiness during the day although they may have enough sleep at night. These attacks usually occur in unusual situations such as standing, eating or the middle of a conversation. Some people find their head falling forward, jaw dropping, knees buckling or even falling to the ground while they are conscious. These attacks may be brought on by emotional situations such as hearty laughter, excitement, sadness or anger.
What it does
ADHD
APO-METHYLPHENIDATE works by improving the activity of certain parts of the brain, which are underactive. APOMETHYLPHENIDATE improves attention (attention span) and concentration, and reduces impulsive behaviour.
Narcolepsy
APO-METHYLPHENIDATE relieves excessive daytime sleepiness in patients suffering from narcolepsy.
When it should not be used

Warnings and precautions
Serious Warnings and Precautions
Drug Abuse and Dependence
Abuse of APO-METHYLPHENIDATE can lead to dependence. Tell your doctor if you have ever abused or been dependent on alcohol or drugs, or if you are now abusing or dependent on alcohol or drugs.
The following have been reported with use of methylphenidate hydrochloride and other medicines used to treat ADHD:
1. Heart-related problems:
- sudden death in patients who have heart problems or heart defects
- stroke and heart attack in adults
- increased blood pressure and heart rate
Sudden death has been reported with drugs used for ADHD treatment in children/adolescents with structural heart abnormalities or other serious heart problems. Although some serious heart problems alone can carry an increased risk of sudden death, APOMETHYLPHENIDATE and APO-METHYLPHENIDATE SR generally should not be used in children, adolescents or adults with known structural heart abnormalities or other serious heart disease or conditions.
Tell your doctor if you or, your child, have any heart
problems, heart defects, high blood pressure, or a family
history of these problems.
Your doctor may wish to check you or your child carefully
for heart problems before starting APOMETHYLPHENIDATE.
Your doctor may wish to check your or your child’s blood
pressure and heart rate regularly during treatment with APOMETHYLPHENIDATE.
Call your doctor right away if you or your child has any signs of heart problems such as chest pain, shortness of breath, or fainting while taking APOMETHYLPHENIDATE
2. Mental (Psychiatric) problems:
- new or worse thoughts or feelings related to suicide (thinking about or feeling like killing yourself) and suicide actions (including suicide attempt, suicidal ideation and completed suicide)
- new or worse bipolar illness, characterized by extreme mood swings, with periods of mania (unusually excited, over-active or un-inhibited) alternating with periods of depression (feelings of sadness, worthlessness or hopelessness)
- new or worse aggressive behaviour or hostility
- new psychotic symptoms (such as hearing voices, believing things that are not true, are suspicious) or new manic symptoms
These new or worse mental problems may be more likely to occur if you/your child have mental disorders that you may or may not know about. Tell your doctor about any mental problems or about any personal or family history of suicide, bipolar illness, or depression you or your child have.
A small number of patients taking ADHD drugs may experience unusual feelings of agitation, hostility or anxiety, or have impulsive or disturbing thoughts such as thoughts of suicide, self-harm or harm to others. Those suicidal thoughts or behaviors may occur at any time during treatment, particularly at the start or during dose changes, and also after stopping APO-METHYLPHANIDATE. Should this happen to you, or to those in your care if you are a caregiver or guardian, consult your doctor immediately. Close observation by a doctor is necessary in this situation.
Call your doctor right away if you or your child have any new or worsening mental symptoms or problems while taking APO-METHYLPHENIDATE, especially seeing or hearing things that are not real, believing things that are not real, or are suspicious.
Tell your doctor immediately if you experience abnormally sustained or frequent and painful erections of the penis on APO-METHYLPHENIDATE treatment or after treatment discontinuation. This can occur in any age group and may need urgent medical treatment.
If you experience a combination of the following symptoms: restlessness, tremor, sudden muscle contractions, abnormal high temperature and nausea and vomiting while taking methylphenidate with medicines that raise the level of serotonin in the body (serotonergic medicines, for example those used to treat depression like sertraline and venlafaxine), stop treatment with methylphenidate and medicines that raise the level of serotonin in the body and tell your doctor immediately.
BEFORE you or your child uses APO-METHYLPHENIDATE talk to your doctor or pharmacist if you or your child:
- Have structural heart abnormalities.
- Have a family history of sudden death or death related to heart problems.
- Have any other current or previous heart problems
- Do strenuous exercise.
- Take other stimulant drugs.
- Have a history of drug or alcohol abuse
- Have motion tics or if any other family members suffer from tics. Signs of tics that are hard to control, repeated twitching of any parts of the body or repeating sounds and words.
- Have someone in your family with Tourette’s syndrome.
- Have had fits (convulsions, epilepsy, seizures) or abnormal EEGs (electroencephalograms).
- Have mild high blood pressure.
- Have an abnormal heart rate or rhythm.
- Have or have had any disorder of the blood vessels in the brain, e.g. weakening of blood vessels (aneurysm), stroke, inflammation of blood vessels (vasculitis).
- Have aggressive behaviour.
- Have any suicidal thoughts or behaviour.
- Have mental problems or family history of mental problems, including psychosis, mania, bipolar illness, depression or suicide.
- Have circulation problems in fingers and toes, including numbness, feeling cold or pain. (This is also known as Raynaud’s)

Before taking APO-METHYLPHENIDATE, tell your doctor if you are pregnant or plan for pregnancy (women and men).
If you take APO-METHYLPHENIDATE, it can be in your breast milk. Do not breast-feed during your treatment with APOMETHYLPHENIDATE. Tell your doctor if you are nursing a baby.
APO-METHYLPHENIDATE may cause dizziness, drowsiness, blurred vision, hallucination or other central nervous system side effects, which can affect concentration. If you experience such symptoms, do not drive or use machines, or do other activities that need quick reactions until you know how this medication affects you.
Monitoring during treatment with APOMETHYLPHENIDATE
To see if APO-METHYLPHENIDATE is having any unwanted effects, the doctor will check from time to time the patient’s health conditions (e.g. blood pressure, heart rate) and will also monitor the growth of children taking APO-METHYLPHENIDATE. Blood tests will be carried out to monitor the amount of blood cells (white blood cells, red blood cells and platelets) if a patient takes APOMETHYLPHENIDATE for a long time.
APO-METHYLPHENIDATE should not be used in children under 6 years of age.
Interactions with this medication
Both your doctor and your pharmacist should also be informed of all medicines you are taking, including herbal medicines or drugs are not taken on a regular basis and are available without prescription.
Do not take APO-METHYLPHENIDATE if you are taking
- A medicine called a monoamine oxidase inhibitor (MAOI, used to treat depression), or have taken an MAOI in the last 14 days. Taking a MAOI with APO-METHYLPHENIDATE may cause a sudden increase in your blood pressure (see When it should not be used).
APO-METHYLPHENIDATE may change the way your body reacts to certain medicines. It is important that you tell your doctor or pharmacist if you are taking any of these medicines, it may be necessary to change the dose or in some cases to stop one of the medicines. These include:

Having an Operation
If you are going to have an operation, tell the doctor that you are on treatment with APO-METHYLPHENIDATE. You should not take APO-METHYLPHENIDATE on the day of your operation if a certain type of anesthetic is used. This is because there is a chance of a sudden rise in blood pressure and heartbeat during the operation.
Taking APO-METHYLPHENIDATE with food and drink
Do not drink alcohol while taking APO-METHYLPHENIDATE. Alcohol may make the side effects of APO-METHYLPHENIDATE worse. Remember that some foods and medicines contain alcohol.
Drug testing
