What Ritalin LA is used for
Ritalin LA contain the active ingredient methylphenidate hydrochloride. Methylphenidate
hydrochloride is a central nervous system stimulant.
Ritalin LA (long-acting) capsules are used to treat Attention Deficit Hyperactivity
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 natural ability.
Ritalin LA should be given as part of a total treatment program for ADHD that may
include other measures (psychological, educational and social). It is not intended
for use in patients who have symptoms due to environmental factors and/or other primary
psychiatric disorders, including psychosis.
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.
Ritalin LA, like all medicines containing central nervous system stimulants, will
be given to you 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 Ritalin LA use in children under 6 years

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
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.

at weekly intervals up to 20 mg to 40 mg each day.

daily dose is 80 mg.

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.
