• Whilst your child is taking Ritalin, your doctor will probably want to carry out blood tests and monitor your child's height and weight from time to time.
• When your child first starts to take Ritalin, they may feel slightly dizzy or sleepy. If so, make sure they avoid activities where this could be dangerous, for example, working machinery, until these effects wear off.
• Your child should not drink alcohol whilst taking this medicine.
• Ritalin can be used in children aged 6 years and over.
• These tablets contain lactose and wheat starch and may be unsuitable for some people.

It is important that your child takes the tablets at the right times. They must be taken as instructed by your doctor. Your doctor will usually start treatment with a low dose, for example, half a tablet once or twice a day, and increase it gradually as required. The maximum daily dose is 6 tablets.

If you are not sure how many tablets your child should take, ask your doctor or pharmacist.

• The tablets should be swallowed with a drink of water.
• Do not stop the tablets suddenly. Ask your doctor first.
• If your child forgets to take a dose, they should take the next dose at the usual time. They should NOT take a double dose.
• If your child accidentally takes too many Ritalin tablets, tell your doctor at once or contact your nearest hospital casualty department.

These tablets sometimes cause unwanted effects in some people. Nervousness and sleeplessness sometimes occur at the start of treatment. If they do not go away, your doctor may decide to reduce the dose or change the times at which your child takes the tablets so that they do not take a dose near bedtime.

If your child gets any of the following tell your doctor:

• Skin rash, itching or bruising
• Persistent sore throat, high temperature, joint pain or muscle cramps
• Increased heart rate or palpitations or chest pain
• Increased hair loss
• Uncontrolled movements
• Severe or unusual mood changes

Other effects which may occur include:

• Some children taking Ritalin for a long time may have slower than normal growth but they usually catch up when Ritalin is stopped.
• Headache, sleepiness or dizziness.
• Blurred vision.
• Reduced appetite or upset stomach. Taking the tablets with food may help.
• Dry mouth.

These effects are often mild and may wear off after

a few days' treatment. If they are severe or last for more than a few days, tell your doctor.

If the tablets upset your child in any other way, tell

your doctor

The expiry date for these tablets is given on the carton. The tablets must not be taken after this date.

Keep the tablets in a cool, dry place out of reach of children. Return any unused tablets to your pharmacist.

REMEMBER: this medicine is for your child. Only a doctor can prescribe it. Never give it to someone else. It may harm them even if they have the same symptoms as your child.
