What happens after an ADHD diagnosis?
Receiving an ADHD diagnosis is a significant moment — for many people, it is the explanation for a lifetime of difficulty. What comes next depends on your preferences, the severity of your symptoms, and the clinician who assessed you.
Medication is the most evidence-based and commonly used treatment for adult ADHD in the UK, recommended by NICE guidelines as a first-line intervention. But it is not mandatory. Some people manage well with psychological support, coaching, lifestyle adjustments, or a combination of these. Medication and therapy are not mutually exclusive — many people use both.
If you were assessed privately and have not yet been diagnosed, you can compare online ADHD assessment clinics or use the NHS Right to Choose scheme for a free assessment. You can also read our ADHD assessment cost guide to understand what a private assessment involves.
If you have been diagnosed and your clinician recommends medication, the next step is titration — the process of finding the right medication and dose for you. This guide explains everything you need to know.
Types of ADHD medication available in the UK
ADHD medications fall into two broad categories: stimulants and non-stimulants. Stimulants are the most commonly prescribed and typically the most effective. They work by increasing the availability of dopamine and noradrenaline in the brain — the neurotransmitters that are underactive in ADHD.
Stimulants
Methylphenidate
Concerta XL, Equasym XL, Medikinet, Ritalin
The most widely prescribed ADHD medication in the UK. Blocks the reuptake of dopamine and noradrenaline, increasing their concentration in the prefrontal cortex. Available in short-acting and extended-release formulations. Extended-release versions (Concerta XL, Medikinet XL) last 8–12 hours; short-acting versions last 3–5 hours.
Lisdexamfetamine
Elvanse (UK brand name), Vyvanse (US)
A prodrug that converts to dexamfetamine in the body, providing a smoother onset and longer duration (up to 14 hours) than methylphenidate. Often prescribed when methylphenidate is ineffective or causes significant side effects. Controlled drug — requires a special prescription process.
Dexamfetamine
Generic / Dexedrine
An older amphetamine-based stimulant still prescribed in the UK, particularly for children or when other stimulants are not tolerated. Short-acting, typically taken 2–3 times daily.
Non-stimulants
Atomoxetine
Strattera (branded), generic atomoxetine
A selective noradrenaline reuptake inhibitor (SNRI). Not a controlled drug and not a stimulant — useful for people with a history of substance misuse or who cannot tolerate stimulants. Takes 4–8 weeks to reach full effect. Approved for adults and children.
Guanfacine
Intuniv
An alpha-2 agonist that acts on noradrenaline receptors. Used primarily for children and adolescents, but increasingly prescribed for adults, particularly for emotional dysregulation and hyperactivity. Often used as an add-on alongside stimulants.

The titration process — what to expect
Titration is the process of finding the right medication and dose for you. ADHD medications are not one-size-fits-all — response varies significantly between individuals, and finding the optimal dose typically takes several months of careful adjustment.
Your clinician will usually start you on a low dose and increase it gradually, checking in every 2–4 weeks to assess effectiveness and side effects. You will typically be asked to rate your symptoms using a standardised scale and to report any side effects such as appetite suppression, sleep disturbance, elevated heart rate, or anxiety. The goal is the lowest effective dose — not the highest tolerated dose.
For most people, titration takes 3–6 months to complete. Some reach their optimal dose quickly; others require multiple medication switches before finding what works. This is normal and expected — it is not a sign that medication will not help you.
What titration typically involves
- Initial prescription at a low starting dose
- Check-in at 2–4 weeks — dose adjusted if needed
- Further adjustments until symptoms are adequately controlled
- Stable dose confirmed — transition to regular prescribing (shared care if NHS)
- Annual review to reassess effectiveness and continued need
NHS vs private prescription costs
How much you pay for ADHD medication depends on how your prescription is managed. There are three main routes.
| Route | Cost per month |
|---|---|
| NHS prescription | £9.90 per item (or free if exempt) |
| Private prescription | £30–£150 per month |
| NHS Prepayment Certificate (PPC) | £31.25 for 3 months / £111.60 for 12 months |
Shared care — transferring from private to NHS prescribing
If you were diagnosed and started medication privately, you can usually transfer ongoing prescribing to your NHS GP under a shared care arrangement. This means the specialist recommends the medication and dose, and your GP writes regular NHS prescriptions — bringing your monthly cost down from £30–£150 to £9.90 per item (or free if exempt).
Not all GPs accept shared care for ADHD medication, particularly for controlled drugs like Elvanse or dexamfetamine. It is worth asking your GP practice about their shared care policy before you start the assessment and titration process — some practices have a list of preferred private providers they will accept shared care from.
If your GP declines shared care without clinical justification, you can contact your local Integrated Care Board (ICB) or seek a second opinion from another GP at the practice.
The UK ADHD medication shortage
Since 2023, the UK has experienced a sustained shortage of ADHD medications — particularly methylphenidate-based products (Concerta XL, Medikinet, Equasym) and lisdexamfetamine (Elvanse). The shortage was caused by a combination of manufacturing disruptions, surging demand as diagnosis rates rose, and global supply chain pressure.
As of April 2026, availability has improved but remains intermittent for some brands and doses. Generic methylphenidate is generally available; branded versions (Concerta XL in particular) are still occasionally out of stock. Elvanse availability has improved significantly from its 2023–2024 peak shortfall.
If your medication is unavailable
- →Ask your pharmacist to check neighbouring branches or order in — supply varies by pharmacy, not just by brand
- →Ask your prescriber if a clinically equivalent alternative can be substituted — generic methylphenidate is equivalent to branded versions
- →Contact your GP or specialist; they can issue a bridging prescription for a different formulation if yours is unavailable
- →Do not abruptly stop controlled ADHD medications — contact your clinician if you are unable to obtain your prescription

Tips for starting ADHD medication
Keep a symptom diary from day one
Before you start medication, note your baseline — how often you lose focus, how long you can concentrate, your energy levels, mood, and sleep. This makes it much easier to assess whether the medication is helping and to report accurately at titration check-ins.
Be patient with the titration process
The first medication you try may not be the right one. It can take several months and multiple adjustments to find the optimal medication and dose. This is not unusual — it is the normal process. Many people try two or three medications before settling on one that works well.
Report side effects promptly and honestly
Common side effects include reduced appetite, difficulty sleeping, dry mouth, and elevated heart rate. These often reduce after the first few weeks. If side effects are significant or persistent, tell your clinician — they can adjust the dose, change the timing, or switch medication.
Take medication at the same time each day
Consistency helps maintain stable blood levels and makes it easier to assess the medication's effect. Extended-release medications (Concerta XL, Elvanse) are typically taken in the morning to avoid sleep disruption.
Understand that medication is a tool, not a cure
ADHD medication helps manage symptoms but does not address underlying executive function difficulties, learned behaviours, or emotional patterns that have built up over years. Many people find a combination of medication and ADHD coaching or CBT more effective than medication alone.
Sort out your prescription route before starting
If you intend to use NHS shared care, confirm your GP accepts this arrangement before beginning titration. Switching from private to NHS prescribing mid-titration can cause delays and gaps in medication.
