What Ritalin 10 is used for
Ritalin 10 tablets have two uses.
They are used to treat Attention Deficit Hyperactivity Disorder (ADHD).
About 3% of children suffer from ADHD. It makes them unable to sit still or concentrate on tasks for any length of time.
They may have trouble learning and doing school work. They frequently become difficult to manage, both in school and at home.
Ritalin 10 is a central nervous system stimulant. It is thought to work by regulating specific chemicals in the brain that
affect behaviour. It helps to focus attention, shut out distraction and allows impulsive people to think before they act.
If successful, it will enhance an inattentive person's natural ability.
This medicine is part of a treatment program that usually includes psychological, educational and social therapy.
Ritalin 10 tablets are also used to treat narcolepsy, a sleep-attack disorder.
People with narcolepsy have recurring attacks of irresistible day-time sleepiness in spite of having enough sleep at night.
Narcolepsy can be diagnosed by a doctor by recording wake-sleep patterns.
Narcolepsy is not a normal fatigue state. This medicine should not be used to prevent or treat normal fatigue.
Ask your doctor if you have any questions about why this medicine has been prescribed for you or your child.
Your doctor may have prescribed it for another purpose.
This medicine is only available with a doctor's prescription and your doctor has special permission to prescribe it.
There is not enough information to recommend its use in children under 6 years old.
Ritalin 10 can be abused or lead to dependence. Keep Ritalin 10 in a safe place to prevent misuse and abuse.
Before you take Ritalin 10
When you must not take it
Do not take Ritalin 10 if you or your child are allergic to methylphenidate (the active ingredient) or to any of the other
ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of
the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
Do not take Ritalin 10 if you or your child have any of the following medical conditions:

an overactive thyroid
heart problems such as heart attack, irregular heartbeat, chest pain (angina), high blood pressure
severe depression or other mental illness

If you are not sure whether any of the above medical conditions apply to you or your child, check with your doctor.
Do not take Ritalin 10 if you or your child are taking a medicine called a monoamine oxidase inhibitor (MAOI) or have been
taking it within the past 14 days.
Taking Ritalin 10 together with MAOI medicines may cause a serious reaction with a sudden increase in body temperature, extremely
high blood pressure and severe convulsions.
Ask your doctor or pharmacist if you are not sure if you or your child have been taking one of these medicines.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
In that case, return it to your pharmacist.
Before you start to take it
Tell your doctor if you or your child are allergic to any other medicines, foods, dyes or preservatives.

Your doctor may want to take special precautions if you or your child have any of the above conditions.
Tell your doctor if you are going to have surgery.
If you are going to have an operation, tell the doctor that you are on treatment with Ritalin LA. You should not take Ritalin
LA on the day of your operation if a certain type of anaesthetic is used. This is because there is a chance of a sudden rise
in blood pressure during the operation.
Tell your doctor if you are pregnant or breast-feeding. Ask your doctor about the risks and benefits of taking Ritalin 10
in this case.
This medicine may affect your developing baby if you take it while you are pregnant. It is not known if the active ingredient
in Ritalin 10 passes into the breast milk. Breast-feeding is not recommended while taking this medicine.
Taking other medicines
Tell your doctor if you or your child are taking any other medicines, including medicines that you buy without a prescription
from a pharmacy, supermarket or health food shop.

medicines that increase blood pressure
alpha 2 agonists like clonidine (used to treat high blood pressure)
warfarin, a medicine used to prevent blood clots
medicines for epilepsy (fits)
medicines for depression, such as tricyclic antidepressants and MAO inhibitors
clonidine
You or your child may need to take different amounts of your medicines or you or your child may need to take different medicines.
Your doctor and pharmacist have more information.
If you have not told your doctor about any of these things, tell him/her before you or your child start taking this medicine.
How to take Ritalin 10
Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
Ritalin 10 is available in tablets containing 10 mg of methylphenidate hydrochloride as the active ingredient.
For children aged 6 or over, the usual starting dose is 5 mg (half a tablet) once or twice each day. If necessary, the dose
can be increased by 5 or 10 mg each week up to a maximum of 60 mg (6 tablets) each day.
For adults, the usual dose is 20 to 30 mg (2-3 tablets) each day but some people may need more or less than that. The maximum
dose is 60 mg (6 tablets) each day.
How to take it
Take the tablets with a full glass of water. If they upset you or your child's stomach, you or your child can take them with
food, but always take them in the same way (e.g. always with food or always without food).
That way the effect will always be the same.
Take the tablets in 2 or 3 doses over the day unless your doctor tells you otherwise. If you find that you or your child
have trouble sleeping, talk to your doctor about the best time to take the last dose of the day.
Each dose is usually taken 1 or 2 hours before the greatest effect is needed. For example, a child may take a dose at 7:00
a.m. so that improved concentration begins when school starts.
How long to take it
Continue taking Ritalin 10 for as long as your doctor tells you.
This medicine helps to control your or your child's symptoms but does not cure your condition. Your doctor will check your
or your child's progress to make sure the medicine is working and will discuss with you how long your treatment should continue.
During treatment for ADHD, your doctor may stop Ritalin 10 every so often (e.g. over weekends or school holidays) to see whether
it is still needed. Breaks from treatment also help to prevent a slow-down in growth that sometimes happens when children
take this medicine for a long time.
If you forget to take it
If you or your child forget to take a dose of Ritalin 10, take the dose as soon as you remember. Then make sure to wait the
same amount of time as usual before you or your child take the next dose. For example, if there are usually 4 hours between
doses, wait 4 hours before taking the next dose and so on for the rest of that day. On the next day go back to your usual
times.
Do not take a double dose to make up for the one that you or your child missed.
Your chance of an unwanted side effect may be increased if you do.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency
at your nearest hospital if you think that you or anyone else may have taken too much Ritalin 10. Do this even if there are
no signs of discomfort or poisoning. Keep the telephone numbers for these places handy.
Some of the symptoms of an overdose may include vomiting, agitation, headache, tremors, muscle twitching, irregular heart
beat, flushing, fever, sweating, dilated pupils, breathing problems, confusion and seizures.
While you are taking Ritalin 10
Things you must do
Take Ritalin 10 exactly as your doctor has prescribed.
Like all stimulants, this medicine may become habit-forming and can be abused by some people. If you or your child take it
correctly as instructed by your doctor, abuse or dependence should not be a problem, either now or later in life.
Be sure to keep all of your doctor's appointments so that your or your child's progress can be checked.
Your doctor will want to check your or your child's blood pressure, height, weight and do blood tests from time to time to
prevent unwanted side effects from happening.
If your child is not growing or gaining height or weight as expected treatment with Ritalin 10 may need to be interrupted.
If you become pregnant while taking Ritalin 10, tell your doctor.
Your doctor can discuss with you the risks and benefits of taking it while you are pregnant.
If you or your child are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Ritalin
10.

Things you must not do
Do not stop your treatment without first checking with your doctor.
If you suddenly stop taking this medicine, your condition may reappear or you may get unwanted effects such as depression.
To prevent this, your doctor may want to gradually reduce the amount of medicine you take each day before stopping it completely.
Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give it to anyone else, even if their condition seems similar to yours.
Things to be careful of
Be careful driving, operating machinery or doing jobs that require you to be alert while you are taking Ritalin 10 until you
know how it affects you.
