Methylphenidate for children

About methylphenidate for children

Methylphenidate belongs to a group of medicines, called stimulants. They work by increasing activity in the brain, particularly in areas that help control attention and behaviour.

Methylphenidate is used to treat children with attention deficit hyperactivity disorder (ADHD). It helps with hyperactivity and impulsive behaviour, and allows them to concentrate better. It is also used to treat adults with ADHD or narcolepsy (a sleep disorder).

Methylphenidate is only available on prescription. It comes as standard (immediate release) tablets and capsules and slow release (also called extended, modified or prolonged release) tablets and capsules.

Some children may need to take both slow release and standard methylphenidate to help improve their ADHD.

For adults aged 18 and over, read our information on methylphenidate for adults.

Key facts

Who can and cannot take methylphenidate

Methylphenidate can be taken by most children aged 4 and over, although, it is not suitable for all children. Tell your child's doctor before they start taking this medicine if:

How and when to give methylphenidate to children

Always follow the advice of your child's doctor and the instructions that come with the medicine. Different brands of methylphenidate tablets and capsules may have different instructions.

Dosage

The usual dose of methylphenidate depends on whether your child has standard or slow release medicine. In some cases, the specialist may prescribe both.

Although standard tablets and capsules are sometimes called immediate release, they can still take a while to start working.

Slow release tablets and capsules are sometimes called extended release, modified release, or prolonged release. These tablets and capsules let the medicine pass into your child's body gradually.

Dose for standard tablets and capsules

The usual starting dose for children is 5mg, given once or twice a day. Your doctor may increase your child's dose gradually (usually weekly) until they find the dose that works best. Your child may need to take it 2 or 3 times a day.

Give your child their methylphenidate first thing in the morning. If they have a second dose, give it to them at around lunchtime (early afternoon) and, if prescribed, a third dose in the late afternoon or evening.

Try to leave at least 4 hours between doses. If your child has a third dose, try to give it to them at least 4 hours before bedtime so it does not affect their sleep.

Although they are called immediate release, it can still take a while for the medicine to work. You may not see any changes in behaviour straight away.

Let your child's school know if they need to take their medicine during the school day.

Dose for slow release tablets and capsules

Slow release tablets and capsules start to work with a first release of the medicine into the body. After that, the medicine continues to release into the body more slowly.

The usual starting dose for:

Check the leaflet that comes with the medicine for when to give it and whether it should be taken with food.

If your child is taking Equasym XL, give them their medicine about 30 minutes before breakfast. If they're taking Medikinet XL, give it to them with or after breakfast.

How to give children tablets or capsules

Give your child the tablets or capsules with a drink of water, milk or juice. Tell them to swallow the medicine whole, not chew it.

If your child has problems swallowing pills, then it's OK to crush standard tablets (Medikinet or Ritalin). Mix the crushed tablets with a small amount of soft food such as yogurt, honey or jam.

Important

Do not crush or break slow release tablets because the medicine will not work properly.

However, if your child takes slow release capsules, you can open the capsule and mix the contents with a small amount of soft food such as yogurt, honey or jam.

Give your child the mixture straight away and tell them to swallow it without chewing.

Will their dose go up or down?

Your child will usually start on a low dose of methylphenidate, taken once or twice a day. The doctor will increase the dose gradually, until they find the dose that works best for your child.

If your child starts on standard methylphenidate, the doctor may later switch them to slow release methylphenidate. They only have to take this once a day.

How long will they take it for?

If methylphenidate is working well to control your child's symptoms, they might need to take it for several months or even years. However, it's not usually a life-long medicine.

Your doctor will usually monitor how your child is every 6 months. This gives them a better idea about how your child is getting on with their medicine and whether they still need it.

What if my child is sick?

If your child is sick (vomits) less than 30 minutes after taking their methylphenidate, give them the same dose again.

If it’s more than 30 minutes after taking their medicine, do not give your child another dose, just wait until their next dose is due.

If your child is sick again, ask your doctor or pharmacist for advice.

What if I forget to give a dose?

If you forget to give your child their medicine, skip the missed dose and wait until it’s time for the next dose. Give them the next dose as usual.

Never give them a double dose to make up for a forgotten dose.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to give your child their medicine.

What if they take too much?

The amount of methylphenidate that can lead to an overdose varies from person to person.

Call 999 or go to A&E if:

Your child takes too much methylphenidate and has:

  • a seizure or fit (uncontrollable jerking and shaking)
