ADHD Medication UK: Types, Side Effects, Prescriptions and Delivery

ADHD Medication
ADHD diagnoses in the UK have risen sharply over the past decade, and for many adults and children, medication is a central part of treatment. ADHD medication UK options are varied and effective, but most are also controlled drugs, so safe prescribing, accurate dispensing and ongoing monitoring matter as much as the medication itself.Understanding how ADHD medication works, who can prescribe it and how prescriptions are fulfilled helps patients, parents and clinicians maintain continuity of care. This guide explains the medication options available, the side effects to look out for, how prescriptions move from clinician to pharmacy, and what safe, reliable fulfilment looks like in practice.

what ADHD medication is available in the UK? ADHD medications fall into two groups. Stimulants, such as Elvanse (lisdexamfetamine), Amfexa (dexamfetamine) and methylphenidate brands including Concerta XL, Medikinet, Xenidate XL and Equasym XL, are usually prescribed first. Non-stimulants, such as atomoxetine and guanfacine, are used when stimulants are unsuitable or poorly tolerated. ADHD medication is only prescribed after a full clinical assessment, and stimulant ADHD medicines are controlled drugs, so prescriptions are typically valid for only 28 days.

Understanding ADHD Medication

ADHD medication works by influencing the brain chemicals dopamine and noradrenaline, which play a role in attention, impulse control and executive function. For many patients, it improves focus, reduces impulsivity and hyperactivity, and supports day-to-day functioning at work, school or home.Medication is only ever prescribed following a full clinical ADHD assessment. It is not a first step, but one part of a wider ADHD treatment plan that may also include behavioural strategies, coaching or therapy.For a closer look at the science, read our guide on how ADHD medication works.

Types of ADHD Medication Available in the UK

ADHD medications fall into two broad categories: stimulants and non-stimulants. Suitability depends on the individual, their response to treatment and any side effects experienced.
Stimulant vs non-stimulant ADHD medication
CategoryCommon MedicationsHow They Work
StimulantsElvanse, Amfexa, Medikinet, Concerta XL, Xenidate XL, Equasym XLIncrease dopamine and noradrenaline activity, usually with faster symptom improvement
Non-stimulantsAtomoxetine, GuanfacineWork more gradually, often used when stimulants are unsuitable or poorly tolerated
Stimulants are usually prescribed first, but some patients, including those with certain cardiac or anxiety conditions, are better suited to a non-stimulant. Dose and release profile are adjusted individually during titration. Our guide to stimulant vs non-stimulant ADHD medication compares the two in more detail.

ADHD Medication Names: Brands and Active Ingredients

Brand / medicineActive ingredientTypeControlled drug?
ElvanseLisdexamfetamineStimulantYes, Schedule 2
AmfexaDexamfetamineStimulantYes, Schedule 2
Concerta XLMethylphenidateStimulant (prolonged-release)Yes, Schedule 2
Medikinet, Xenidate XL, Equasym XLMethylphenidateStimulantYes, Schedule 2
AtomoxetineAtomoxetineNon-stimulantNo
GuanfacineGuanfacineNon-stimulantNo
Different modified-release methylphenidate brands release the medicine at different rates through the day, so they are usually prescribed by brand and should not be swapped without the prescriber’s agreement.

How Long Do ADHD Medications Last?

This varies by medicine, brand and individual. As examples from the official UK product information:
  • Elvanse is taken once a day in the morning. In clinical studies, effects were still measurable 13 hours after dosing in children and 14 hours in adults.
  • Concerta XL is taken once a day in the morning. In clinical studies, effects were maintained until 12 hours after dosing.
If your medication seems to wear off too early, speak to your prescriber rather than taking an extra dose.

Who Can Prescribe ADHD Medication?

ADHD medication can be prescribed by psychiatrists, specialist paediatricians and other appropriately trained clinicians, either through the NHS or via a private ADHD prescription. Some patients are managed under shared care, where a specialist initiates treatment and a GP continues prescribing once the dose is stable. Nurse prescribers with relevant qualifications can also prescribe within their scope of practice.Prescriptions may be issued electronically or on paper, but because stimulant ADHD medicines are controlled drugs, they must meet strict legal requirements and are typically valid for only 28 days from the date of issue.

How ADHD Prescriptions Are Processed

Once issued, an ADHD prescription must be verified and dispensed correctly. A specialist ADHD pharmacy checks the prescription meets controlled drug regulations, confirms stock availability and communicates directly with the prescribing clinic if a query arises, reducing delays compared with a general pharmacy handling an unfamiliar medication.Repeat prescriptions rely on the same accuracy. Clear ADHD repeat prescription support, including reminders before medication runs out and direct clinic-to-pharmacy communication, helps prevent treatment gaps caused by expired or delayed prescriptions.

Common Side Effects of ADHD Medication

Side effects vary by medicine and person, and many are most noticeable when starting treatment or after a dose increase. Common side effects include appetite changes, sleep disturbance and mood changes. The official product information for two widely used stimulants lists these as very common (more than 1 in 10 people):
Elvanse (lisdexamfetamine)Concerta XL (methylphenidate)
Decreased appetiteReduced appetite
Difficulty sleepingDifficulty sleeping
HeadacheHeadache
Dry mouthNervousness
Upper stomach painCold-like symptoms
Weight loss
Stimulants can also raise heart rate and blood pressure, which is why these are checked regularly. Non-stimulants have their own side effect profiles; always read the Patient Information Leaflet that comes with your medicine.

When to get urgent medical help

Contact a doctor straight away, or call 999, if you or your child has:
  • Chest pain, a racing or uneven heartbeat, or fainting
  • Hallucinations, or extreme high mood (mania)
  • Thoughts of suicide or self-harm, or severe mood changes
  • A seizure (fit)
  • Signs of a serious allergic reaction, such as swelling of the face or difficulty breathing

Managing ADHD Medication Safely

Safe use involves more than taking a tablet each day. Patients and parents should be aware of the following:
  • Take medication at the same time each day, as advised by the prescriber
  • Do not double a dose if one is missed; seek advice instead
  • Attend scheduled reviews to monitor effectiveness and side effects
  • Report side effects such as appetite changes, sleep disturbance or mood changes
  • Store medication securely, given its controlled drug status
Regular reviews, usually every three to six months once stable, allow the prescriber to adjust dose or medication if needed.

What is checked at ADHD medication reviews?

For stimulant medicines such as Elvanse and Concerta XL, the product information sets out regular checks of:
  • Blood pressure and heart rate
  • Weight and appetite, and height in children and teenagers
  • Mood and mental wellbeing
These checks are a normal part of safe treatment. If your medication no longer seems to help, read what happens if ADHD medication stops working and whether you can change ADHD medication.

Can I drive while taking ADHD medication?

Stimulant ADHD medicines such as Elvanse and Concerta XL can cause dizziness, drowsiness and blurred vision. Do not drive until you know how your medicine affects you. For UK rules on driving with prescribed medicines, see GOV.UK: Drugs and driving, the law.

ADHD Medication Shortages

National ADHD medication shortages have affected the UK in recent years, driven by global manufacturing issues. When a shortage occurs, a well-organised pharmacy monitors stock daily, contacts patients early and liaises with the prescriber about alternatives, rather than leaving patients to discover an empty shelf. Continuity of care during a shortage depends on this proactive communication between pharmacy, clinic and patient.Do not change your medicine, brand or dose without advice, and never buy ADHD medication from a website, social media seller or anyone without a valid prescription.

ADHD Medication Delivery in the UK

Many patients now choose ADHD medication delivery UK-wide rather than collecting prescriptions in person. Because stimulant ADHD medicines are controlled drugs, delivery must be tracked, require a signature on receipt and use discreet, secure packaging, with the pharmacy maintaining full record-keeping in line with controlled drug law.ADHD prescription delivery and ADHD medication home delivery services are especially valuable for patients who live rurally, have mobility difficulties, or prefer consistent monthly fulfilment without visiting a pharmacy in person.
