ADHD Medication in the UK: A Plain-English Guide

ADHD medication is effective for approximately 70–80% of people who try it — but navigating the UK prescribing system after a private diagnosis can be confusing. This guide explains the different medications, how titration works, and how to get your GP involved in prescribing.

Types of ADHD Medication Available in the UK

Medication type	Brand names	Typical starting point
Methylphenidate (stimulant)	Ritalin, Concerta XL, Medikinet, Equasym	Most common first-line for adults and children
Lisdexamfetamine (stimulant)	Vyvanse, Elvanse	When methylphenidate hasn’t worked or caused side effects
Atomoxetine (non-stimulant)	Strattera	Preferred when anxiety is significant or stimulants aren’t suitable
Guanfacine (non-stimulant)	Intuniv	For children; can help with emotional dysregulation
Bupropion (off-label)	Zyban	Occasionally used in adults when other options haven’t worked

What Is ADHD Medication Titration?

Titration is the process of finding the right medication and the right dose for you. It typically involves:

Starting at a low dose
Monthly review appointments to assess effectiveness and side effects
Gradual dose increases until an optimal response is achieved or side effects prevent further increases
Stabilisation and longer-term monitoring once the right dose is found

Titration typically takes 3–6 months. If medication A doesn’t work well, you may try medication B. This is normal and expected.

How Does Prescribing Work After a Private ADHD Diagnosis?

After a private ADHD diagnosis in the UK, there are two main routes to medication:

Route 1: Private Prescribing Throughout

Your private provider continues to prescribe throughout titration and beyond. This is faster and simpler but ongoing costs are significant — private prescriptions for ADHD medication can cost £30–£150 per month depending on the medication and dose.

Route 2: NHS Shared Care Agreement

Your private provider initiates diagnosis and prescribing, then transfers prescribing to your NHS GP under a shared care agreement. Once stable, your GP prescribes at NHS cost (a standard prescription charge per item). This is the most cost-effective long-term route but requires your GP to agree to the shared care arrangement.

Some GPs refuse shared care prescribing after private ADHD diagnoses. If your GP refuses, ask them to refer to NHSE guidance on shared care. If they still refuse, you can ask to be referred for an NHS assessment, or continue with private prescribing until you can access NHS care.

ADHD Medication Costs

Private prescription: £30–£150 per month depending on medication and dose
NHS prescription (shared care): Standard NHS prescription charge — £9.90 per item as of 2026, or free if exempt (under 16, over 60, certain conditions, or with a prepayment certificate)
Prepayment certificate: If taking multiple medications, a prepayment certificate (currently £111.60 per year) can significantly reduce costs

Frequently Asked Questions

Can I get ADHD medication without seeing a psychiatrist?

In the UK, ADHD medication can only be initiated by a specialist — a consultant psychiatrist or specialist paediatrician. Once initiated and stabilised, a GP can continue prescribing under a shared care agreement. You cannot get ADHD stimulant medication from a GP alone without specialist initiation.

How long does it take for ADHD medication to work?

Stimulant medications (methylphenidate and lisdexamfetamine) typically produce a noticeable effect on the first day you take them, though finding the right dose takes months. Non-stimulants like atomoxetine take 4–6 weeks to reach full effectiveness. You will know relatively quickly whether a medication is helping.

What are the most common ADHD medication side effects?

Common side effects of stimulant ADHD medications include: reduced appetite (particularly at lunchtime), difficulty sleeping if taken too late in the day, raised heart rate, irritability as the medication wears off (‘rebound’), and occasionally increased anxiety. Most side effects can be managed by adjusting dose or timing. Your prescriber should monitor these.
