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.
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:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The amount of methylphenidate that can lead to an overdose varies from person to person.
Your child takes too much methylphenidate and has:
Take the methylphenidate packet, or the leaflet inside it, plus any remaining medicine with you.
If you need advice for a child under the age of 5 years, call 111.
Keep methylphenidate in a cupboard. Make sure children cannot see or reach this medicine.
Like all medicines, methylphenidate can cause side effects, although not everyone gets them.
These common side effects may happen in more than 1 in 100 people:
Keep giving your child the medicine, but tell your doctor if they bother your child or do not go away:
Serious side effects are uncommon and happen in less than 1 in 100 people.
Tell your doctor straight away if your child:
Methylphenidate can also cause a small increase in blood pressure and pulse rate. For this reason, your doctor will usually measure your child’s blood pressure and pulse every 6 months.
If your child takes methylphenidate for longer than a year, it can slow down their growth. However this happens in less than 1 in 10 children.
Your doctor will check your child’s height, weight and appetite every 6 months to make sure they are growing OK.
In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to methylphenidate.
You or the person who's unwell may also have a rash that's swollen, raised, itchy, blistered or peeling.
These can be signs of a serious allergic reaction and may need immediate treatment in hospital.
Information:Do not drive yourself to A&E.
The person you speak to at 999 will give you advice about what to do.
These are not all the side effects of methylphenidate. For a full list, see the leaflet inside the medicine packet.
Information:You can report any suspected side effect using the Yellow Card safety scheme.
What to do about:
There are some medicines that can affect the way methylphenidate works.
If your child is taking any of the following medicines, talk to your doctor or pharmacist before giving them methylphenidate:
Some cough and cold medicines can affect blood pressure so speak to your pharmacist or doctor if you're buying these for your child. It’s important to check whether they are OK for them to have while taking methylphenidate.
There's very little information about taking herbal remedies and supplements while taking methylphenidate. Check with your doctor or pharmacist before giving any to your child.
Some studies have suggested that omega-3 and omega-6 supplements can help with ADHD. However, the evidence is limited and more research is needed.
Tell your doctor or pharmacist if you're taking any other medicines, including herbal medicines, vitamins or supplements.
Methylphenidate belongs to a group of medicines called stimulants. They increase activity in the brain, particularly in areas that help control attention and behaviour.
It's not known exactly how methylphenidate works. It's thought to boost the levels of chemicals called dopamine and noradrenaline in the brain.
This can increase activity in the parts of your child's brain that control attention and behaviour.
This makes them less hyperactive or impulsive. It will also help them to pay attention and concentrate better.
How long does it take to work?When your child first starts taking methylphenidate they will be on a low dose. Your doctor will usually increase this gradually until they find the dose that works for your child.
This means it might take a few weeks before you see any benefits. When your doctor has found the right dose, methylphenidate should start to work within 30 to 60 minutes of your child taking it.
The medicine makes your child less hyperactive or impulsive, and helps their concentration. How quickly it works depends on whether it's standard or slow release.
How long will my child take it for?Your child may need to take methylphenidate for several months or even years. They will not usually need to take it for the rest of their life.
Your child will have regular check-ups, usually every 6 months or so.
Your doctor may recommend stopping methylphenidate for a while, or reducing the dose. This will normally be during the school holidays and can be called “a medicine break”. This is to check whether it’s still helping.
As your child gets to puberty, or just after, the doctor may stop their methylphenidate. But if the medicine is still helping, they may recommend that your child keep taking it, even as an adult.
Is it safe to take for a long time?There is no evidence that methylphenidate is harmful as long as it is taken exactly as prescribed and your child is monitored carefully. This is why it’s a good idea for them to have regular reviews with their doctor to check whether it’s still needed.
What will happen if my child stops taking it?Only stop giving your child methylphenidate if your doctor tells you to.
If your child suddenly stops taking methylphenidate, you may notice withdrawal symptoms such as depression.
Talk to your doctor if you want to stop giving your child methylphenidate. They may want to slowly reduce the amount that your child takes before stopping completely. This is to help avoid any extra side effects.
Is it addictive?As long as you follow your doctor’s instructions carefully, methylphenidate does not generally cause addiction issues.
Do not stop giving methylphenidate to your child suddenly. Talk to your doctor first, as they may want to reduce the dose gradually. This reduces the risk of your child having extra side effects when they stop taking this medicine.
Addiction problems usually only occur if you give methylphenidate more often than prescribed, or at a higher dose than recommended.
Does my child need to stick to the same brand of methylphenidate?Once your child is on a brand of methylphenidate that works for them, they'll usually keep taking the same brand. This is because it can be a problem to change brands, particularly if they're taking slow release tablets or capsules.
Different brands of slow release methylphenidate tablets and capsules work differently in how they release the medicine into the body. This can affect how they work to manage symptoms. Side effects can also vary.
Different brands also have different instructions for how and when to take it, such as whether to take it with food.
If your child does need to change brands, check the instructions that come with the medicine carefully.
Can my child take it with painkillers?You can give your child painkillers such as paracetamol or ibuprofen, unless your doctor has told you not to.
Is there any food or drink they need to avoid?There's no particular food or drink that your child needs to avoid when taking methylphenidate.
Are medicines the first treatment option for children with ADHD?If a child has ADHD, their doctor will usually only prescribe a medicine if other treatments have not helped. Their symptoms may still be causing problems, even after trying practical things like:
Medicines are usually only used for ADHD as part of a treatment programme. Other treatments can include:
If you have any questions or worries about your child’s medicine, speak to your doctor.
What if methylphenidate is not helping my child?Some people find that methylphenidate does not work for their child. In this case, the doctor may recommend trying a different medicine or psychological treatments.
Other medicines for ADHD include dexamfetamine, lisdexamfetamine and atomoxetine.
Non-medicine treatments for ADHD include, behavioural therapy and talking therapy.
Speak to your doctor if you are interested in finding out about alternative treatments. Do not stop giving your child methylphenidate without talking to your doctor first.
Can taking supplements help ADHD?Some studies have suggested that omega-3 and omega-6 supplements can help with ADHD. However, the evidence is very limited and more research is needed.
Talk to your doctor before giving any supplements to your child. This is because some can react with medicine - causing side effects, or can make the medicine work less well.
