UK ADHD medication falls into two broad classes: stimulants (methylphenidate, lisdexamfetamine, dexamfetamine) and non-stimulants (atomoxetine, guanfacine). All are prescription-only, all require a formal diagnosis first, and the stimulant options are controlled drugs under UK law. This guide covers what's actually available, how it's chosen, and where each medicine fits.
Stimulant medications
Stimulants are usually the first medication class tried for both children and adults diagnosed with ADHD, because the evidence base for their effectiveness is strong and their effects are often noticeable quickly.
Methylphenidate
The most widely prescribed UK ADHD medication. Sold under several brand names with different release profiles — Concerta XL and Medikinet XL are once-daily extended-release formulations, Equasym XL is another extended-release option, and immediate-release Ritalin is taken multiple times a day. Read our full methylphenidate page.
Lisdexamfetamine (Elvanse)
A once-daily prodrug — it's inactive until the body converts it to dexamfetamine, which produces a smoother, longer-lasting effect than immediate-release amphetamine products. It's the medication most functionally comparable to Adderall available in the UK. Read our full lisdexamfetamine page.
Dexamfetamine
A shorter-acting amphetamine-type stimulant, sometimes prescribed on its own, particularly when longer-acting options aren't well tolerated or don't suit someone's daily routine. Read our full dexamfetamine page.
Non-stimulant medications
Non-stimulants are generally considered when stimulants aren't suitable — due to other health conditions, a history of substance misuse, unacceptable side effects, or personal preference.
Atomoxetine (Strattera)
A non-stimulant, non-controlled selective noradrenaline reuptake inhibitor. It takes longer to reach full effect than stimulants but doesn't carry the same controlled-drug restrictions. Read our full atomoxetine page.
Guanfacine (Intuniv)
An extended-release non-stimulant, originally developed for blood pressure, now used in ADHD treatment — often when stimulants and atomoxetine haven't been suitable. Read our full guanfacine page.
How UK prescribers choose between them
There's no single "best" ADHD medication — the right choice depends on the individual's symptom pattern, other health conditions, lifestyle, and how they respond during a supervised titration period. NICE guideline NG87 sets out the framework UK specialists follow: for children aged 5 and over, methylphenidate is usually offered first, with lisdexamfetamine considered next if a six-week trial doesn't help enough; for adults, methylphenidate and lisdexamfetamine are both considered first-line options. A non-stimulant (atomoxetine or guanfacine) is generally considered only after stimulant options haven't been suitable or effective.
Where Adderall fits into this picture
It doesn't — at least not as a UK-licensed product. Adderall (mixed amphetamine salts) has no UK marketing authorisation, so it isn't one of the medicines a UK prescriber can choose from. People researching Adderall in a UK context are usually looking for the closest equivalent, which is generally lisdexamfetamine. See our dedicated guides on Adderall's UK availability and Adderall alternatives for more detail. If you've specifically come across the 30mg strength, Adderall 30mg in the UK explains what that means across Adderall's immediate-release and XR formulations.
What "finding the right medication" actually involves
It's common to try more than one medication, dose, or formulation before settling on what works. Response to ADHD medication is individual — two people with very similar symptom profiles can respond quite differently to the same drug, and there's no reliable way to predict in advance which option will suit someone best. This is why titration (the gradual dose-finding process) and regular review appointments are a standard, expected part of treatment, not a sign that something has gone wrong. If a first medication doesn't work well or causes unacceptable side effects, switching to a different stimulant, a different formulation, or a non-stimulant is a normal next step, decided together with your prescriber.
General safety considerations
Every ADHD medication class carries its own specific precautions, covered in detail on each medicine's own page, but some monitoring principles apply across the board. Prescribers typically check cardiovascular health (heart rate, blood pressure) before starting stimulant medication and periodically during treatment, since stimulants can affect both. Growth (height and weight) is monitored in children on stimulant medication. Mood and sleep are reviewed regularly, since both stimulants and non-stimulants can affect them, particularly during dose changes. None of this is a reason to avoid treatment — it's the normal safety framework UK prescribers work within, and it's a large part of why ADHD medication requires ongoing specialist or GP-shared-care oversight rather than a one-off prescription.
Getting started
Every route to ADHD medication in the UK starts the same way: a GP conversation, a referral for specialist assessment, and a formal diagnosis. See our ADHD diagnosis guide and ADHD treatment guide for the full pathway.
