Equasym XL capsules contain the active ingredient methylphenidate hydrochloride, which is a type of medicine called a stimulant. It is used to treat attention deficit hyperactivity disorder (ADHD) in children.

How does it work?

Stimulants are related to amphetamines, which might make them seem an odd choice for treating hyperactive children, because stimulants increase activity in the brain and normally make people more alert and active. However, stimulants at the doses used for ADHD have the opposite effect.

Methylphenidate works by affecting some of the natural chemicals that are found in the brain. In particular, it increases the activity of chemicals called dopamine and noradrenaline in areas of the brain that play a part in controlling attention and behaviour. These areas seem to be underactive in children with ADHD. It is thought increasing the activity of these chemicals improves the function of these underactive parts of the brain. We still don’t fully understand how stimulants work in children with ADHD, and they don’t work for everyone. But they can be very useful at helping some children to learn to control their behaviour.

Equasym XL capsules are a modified-release form of methylphenidate. The capsules are designed to release 30 per cent of the methylphenidate immediately, giving an initial dose of medicine for the morning. The remaining 70 per cent of the dose is released gradually over eight hours. This means the capsules provide enough medicine to cover the school day, without your child needing to take a dose at lunchtime.

What is Equasym used for?

  • Attention deficit hyperactivity disorder (ADHD).

Methylphenidate is not used for all children with ADHD. It is used as part of a comprehensive treatment programme for ADHD that includes psychotherapy and behavioural management techniques, and is only used in children in whom these treatments have proved to be insufficient on their own. It should only be used under the supervision of a specialist in childhood behavioural disorders, and only after the severity of the child's symptoms has been thoroughly assessed.

How do I take it?

  • The usual starting dose of Equasym XL is one 10mg capsule daily. Your doctor may increase this to either one 20mg or one 30mg capsule daily, depending on the response to the medicine. The maximum daily dosage of Equasym XL is 60mg.
  • Equasym XL capsules should be taken once a day in the morning, before breakfast.
  • The capsules should be swallowed whole with a drink. They must not be chewed, broken or crushed, as this will stop the modified-release action from working.
  • For children who cannot swallow the capsules whole, Equasym XL capsules can also be opened and the capsule contents sprinkled onto a spoonful of soft food that doesn't need chewing, such as apple sauce. This should be given immediately and followed with a drink. The sprinkled capsule contents should not be crushed or chewed, as this will stop the modified-release action from working. The opened capsule contents should not be stored for later use.
  • If you forget to take your capsule in the morning you should not take it later in the day, because this may cause problems with sleeping during the night. Instead, leave out the forgotten dose and just take your next dose as usual the following morning. Don'’t take a double dose to make up for a missed dose.
  • If symptoms have not improved after one month of taking this medicine your doctor may decide to stop treatment. Where symptoms have improved, the medicine should be stopped from time to time, usually at least once a year, so that the condition can be assessed and to check if the medicine is still needed. However, in both cases, this medicine must not be stopped suddenly without your doctor's advice. When stopping treatment, the medicine should be withdrawn gradually, following the instructions given by your doctor.

How can this medicine affect other medicines?

  • You should tell your doctor what medicines your child is already taking before they start treatment with this medicine. This includes medicines bought without a prescription and herbal medicines. Likewise, once treatment has started you should always check with your doctor or pharmacist before using any new medicines, to make sure the combination is safe.
  • If this medicine is taken within 14 days of taking a monoamine oxidase inhibitor antidepressant (MAOI, eg tranylcypramine, phenelzine, isocarboxazid, moclobemide) there may be a risk of a dangerous rise in blood pressure (hypertensive crisis). For this reason methylphenidate should not be taken by people who have taken an MAOI in the previous 14 days.
  • Check with your pharmacist before giving cough and cold remedies to children taking methylphenidate, as these types of medicines sometimes contain ingredients that may affect blood pressure, and could be unsuitable to use in combination with methylphenidate.

Methylphenidate may increase the blood levels of the following medicines:

  • the antiepileptic medicines fosphenytoin, phenytoin, primidone and phenobarbital
  • warfarin
  • tricyclic antidepressants, eg imipramine.

If you have any more questions please ask your Pharmacist.
