What Ritalin 10 is used for
Ritalin 10 tablets contain the active ingredient methylphenidate hydrochloride. Methylphenidate hydrochloride is a central nervous system stimulant.
Ritalin 10 tablets have two uses. They are used to treat:
Attention Deficit Hyperactivity Disorder (ADHD); and
narcolepsy, a sleep-attack disorder.
Your doctor may have prescribed it for another purpose.
This medicine should not be used to prevent or treat normal fatigue.
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 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.
Narcolepsy
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.
Ask your doctor if you have any questions about why this medicine has been prescribed for you/your child.
Ritalin, like all medicines containing central nervous system stimulants, will be given to you/your child only under close medical supervision and after diagnosis.
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.

How to take Ritalin 10
Your doctor will decide on the most suitable dosage according to the individual patient's medical need and response.
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.
Do not exceed the recommended dose.
The maximum dose is 60 mg (6 tablets) each day.
How to take it
You can take Ritalin 10 tablets with or without food. Take the tablet(s) 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/ your child's progress to make sure the medicine is working and will discuss with you how long your treatment should continue.
Treatment for ADHD varies in length from patient to patient. 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/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/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/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.

vomiting
agitation
headache
tremors
muscle twitching
irregular heart beat
flushing
fever
sweating
dilated pupils
breathing problems
confusion
