Biggest variable
Whether your GP agrees shared care
The three separate costs
People usually ask what ADHD medication costs and get a confusing answer, because three different things are being charged for and they behave differently.
1. The assessment
A diagnosis has to come before any prescription. On the NHS this is free at the point of use after a GP referral. Privately it is a one-off fee: at The ADHD Centre, £695 for an online assessment and £1,095 in person in London or Manchester.
2. Titration
Finding the right dose takes several weeks of appointments and dose changes. On the NHS this is included. Privately it is charged separately from the assessment, because the number of reviews varies. Our guide to titration explains what the period involves.
3. The ongoing prescription
Once your dose is stable you need a new prescription roughly every month for a stimulant, because controlled drugs are treated differently from ordinary medicines rather than issued as repeat prescriptions. At The ADHD Centre we issue 30 tablets at a time. Whether that is an NHS or a private cost depends entirely on whether your GP agrees shared care, which is the single biggest variable in the whole calculation.
What it costs on the NHS
Assessment, titration and review are free at the point of use. What you pay is the prescription charge, and only in England.
Prescriptions are free in Scotland, Wales and Northern Ireland. In England a standard charge applies per item, unless you are exempt. Exemptions include being under 16, being 60 or over, being in full-time education under 19, holding a valid medical exemption certificate, and receiving certain benefits. The current charge and the full list of exemptions are published by the NHS.
Prepayment certificates are worth checking
If you pay for more than a few prescription items a year in England, a prepayment certificate usually costs less than paying per item. Because a stimulant prescription covers about a month at a time, ADHD medication generates more items per year than most treatments, which makes a certificate worth doing the arithmetic on.
One point catches people out. A month's supply at a time means twelve or thirteen prescriptions a year rather than the four or six that a repeat medicine would generate. That is a consequence of stimulants being Schedule 2 controlled drugs rather than anything specific to ADHD.
What it costs privately
A private route has a clear one-off cost and a less predictable ongoing one.
The assessment is fixed: £695 online, £1,095 in person. Titration is charged per review, and the number of reviews depends on how quickly a suitable dose is found, which varies between people and between medicines.
Ongoing private prescriptions have two components: the fee for issuing the prescription, and the cost of the medicine itself at the pharmacy.
For the licensed UK medicines, expect the medicine itself to cost somewhere between £50 and £200 a month. Where you sit in that range depends on the drug, the brand, the dose and the pharmacy, and prices change, so it is always worth asking a pharmacy for a current price for your specific product rather than relying on a figure published anywhere. Generic methylphenidate sits at the lower end; branded modified-release products and higher doses sit at the upper end.
One medicine sits far outside that range
Adderall XR is not licensed in the UK and is not available on the NHS. Where it is supplied at all it is as an unlicensed import on a private specialist prescription, and it typically costs around £600 a month. It is the only ADHD medicine commonly asked about that falls outside the £50 to £200 range, and by a wide margin.
Clinical context
Non-stimulants can be cheaper to run
Atomoxetine and guanfacine are not controlled drugs, so prescriptions are not limited in the same way and can be issued as repeats. That means fewer prescription events per year and, in England, fewer charges.
This is never the primary reason to choose a medicine, but where two options are clinically reasonable it is a fair thing to factor in and to raise with your prescriber.
How to plan for it
The useful question is not what one prescription costs but what a year costs, because the pattern of spending is uneven. There is a larger amount at the start, a variable period during titration, then a steadier ongoing figure.
- The assessment is one payment, known in advance
- Titration is several smaller payments across a few weeks, and the number varies
- The ongoing prescription is roughly twelve to thirteen events a year for a stimulant
- The licensed medicines themselves run about £50 to £200 a month privately
- In England, a prepayment certificate caps the NHS charge across a year
- Non-stimulants generate fewer prescription events because they can be repeats
Two things are worth asking before you commit. Ask any private provider what titration is likely to cost in total rather than per appointment, and ask your GP practice whether they would consider shared care after a private diagnosis. Those two answers determine most of the year-one figure.
It is also worth knowing that costs can change mid-treatment. A switch between medicines, a change of brand during a supply problem, or a move between areas with different NHS prescription rules will all shift the arithmetic.
Common questions
How much does ADHD medication cost in the UK?
On the NHS, the standard prescription charge per item in England, and nothing in Scotland, Wales and Northern Ireland. Privately, the licensed medicines themselves typically cost between £50 and £200 a month, plus the prescription fee. Adderall XR is the exception at around £600 a month, because it is an unlicensed import.
Why is Adderall so much more expensive?
Because it is not licensed in the UK. It has to be imported under a specials licence on a private prescription, which prices it at around £600 a month against £50 to £200 for the licensed alternatives. There is no NHS route and no shared care for it.
How much is a private ADHD assessment?
At The ADHD Centre, £695 for an online assessment and £1,095 in person in London or Manchester. Titration and ongoing prescriptions are charged separately.
Is ADHD medication free on the NHS?
In Scotland, Wales and Northern Ireland prescriptions are free. In England the standard charge applies per item unless you are exempt.
Will a prepayment certificate save me money?
Often, in England. Because a stimulant prescription covers about a month at a time, ADHD medication generates around twelve to thirteen items a year, which is usually more than the break-even point for a certificate.
Does a private diagnosis mean paying privately forever?
Not necessarily. If your GP agrees shared care once your dose is stable, ongoing prescribing moves onto the NHS. That agreement is voluntary and a practice can decline.
Why do I need a new prescription every month?
Stimulants are Schedule 2 controlled drugs, so they are treated differently from ordinary medicines rather than issued as repeat prescriptions, and each prescription covers about a month. At The ADHD Centre we issue 30 tablets at a time. Non-stimulants are not subject to this.
