Ritalin LA is a stimulant that increases attention and decreases impulsiveness and hyperactivity in patients with ADHD. Ritalin
LA 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

How to take Ritalin LA
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 LA is available in long-acting capsules containing 10 mg, 20 mg, 30 mg, 40 mg or 60 mg of methylphenidate hydrochloride
as the active ingredient.
Your doctor will usually start with a low dose and, if necessary, increase it gradually at weekly intervals up to 20 mg to
40 mg each day.
Do not exceed the maximum recommended dose.
In children, the maximum recommended daily dose is 60 mg. In adults, the maximum recommended daily dose is 80 mg.
How to take it
You can take Ritalin LA with or without food. Swallow the capsules whole as a single dose in the morning with a full glass
of water. Do not crush or chew the capsules.
If you have trouble swallowing the capsules, you can carefully open them and sprinkle the contents (little beads) over a small
amount of soft food (e.g. applesauce).
The soft food should not be warm as this could affect the special properties of the beads.
Immediately eat all of the soft food and Ritalin LA mixture. Do not store any of the soft food that has been mixed with Ritalin
LA for future use.
If the capsules 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.
How long to take it
Continue taking Ritalin LA 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.
Treatment for ADHD varies in length from patient to patient. During treatment for ADHD, your doctor may stop Ritalin LA 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 LA capsules and you remember before mid-day, take the dose as soon as you remember.
Then go back to your usual schedule on the following day.
If you do not remember before mid-day, miss your dose of Ritalin LA for that day and wait until the following morning to take
your next dose.
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 LA. 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 LA
Things you must do
Take Ritalin LA exactly as your doctor has prescribed.
Like all stimulants, this medicine may become habit-forming and can be abused by some people. If you 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 LA may need to be interrupted.
If you become pregnant while taking Ritalin LA, tell your doctor.
Your doctor can discuss with you the risks and benefits of taking it while you are pregnant.

Tell any doctor, dentist or pharmacist who treats you that you are taking Ritalin LA.
Things you must not do

Drinking alcohol is not recommended because it can worsen some of the unwanted effects of this medicine, such as dizziness

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.
You will need medical supervision after having interrupted the treatment.
Do not change the dose without talking to the doctor. If you have the impression that the effect of Ritalin LA is too strong
or too weak, talk to the doctor.

know how it affects you.
This medicine may cause hallucinations, dizziness, drowsiness, blurred vision or other central nervous system side effects
which can affect concentration in some people. If you have any of these symptoms, do not drive, use machines or do anything
else that needs quick reactions or could be dangerous.

taken earlier unless your doctor recommends otherwise.

If you are going to have an operation, tell the doctor that you are on treatment with Ritalin LA. You should not take Ritalin

in blood pressure during the operation.
