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 schoolwork. 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.

Do not take Ritalin 10 if you are taking a medicine called a monoamine oxidase inhibitor (MAOI) or have been taking it within the past 14 days.

Ask your doctor or pharmacist if you are not sure if you 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.

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 your stomach, you 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 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 symptoms but does not cure your condition. Your doctor will check your 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 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 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 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.
