Can you get medical cannabis for neuropathic pain in the UK?

Neuropathic pain — pain caused by damage to the nerves themselves, rather than to tissue — is one of the more commonly assessed reasons for a private prescription in the UK. It is also the pain condition with the most randomised trial evidence behind it, though “most” here still means modest.

Is neuropathic pain treated with medical cannabis in the UK?

It is assessed privately, and it is one of the more frequent reasons UK specialists consider a cannabis-based medicine. It is not treated this way on the NHS, where nerve pain is managed with the medicines recommended in NICE guideline CG173.

Neuropathic pain covers sciatica and other radicular pain, diabetic peripheral neuropathy, post-herpetic neuralgia after shingles, trigeminal neuralgia, nerve pain after surgery or injury, and the nerve pain that comes with conditions such as multiple sclerosis. It typically responds poorly to ordinary painkillers, which is why the standard first-line medicines are amitriptyline, duloxetine, gabapentin or pregabalin — and why people who cannot tolerate those are the ones who tend to end up asking about cannabis.

Being unable to tolerate first-line treatment is a legitimate clinical reason to consider something else. It is not, on its own, a guarantee that anything else will work.

What the evidence actually shows

Neuropathic pain has been studied more than most conditions on this page, and the honest summary of that literature is: a real but small average effect, achieved at the cost of side effects that many people find unacceptable.

A Cochrane systematic review of cannabis-based medicines for chronic neuropathic pain in adults pooled the randomised evidence and found these medicines more effective than placebo for pain, sleep problems and psychological distress — while rating the quality of that evidence from very low to moderate, and noting that somnolence, sedation, confusion and psychosis limit their clinical usefulness. Roughly speaking, a modest number of people get a worthwhile benefit, a similar number stop because of how it makes them feel, and the averages hide both.

That is a more supportive evidence base than most conditions in this knowledge base can claim. It is still not strong enough for NICE to recommend routine use, and your specialist should say so.

What a specialist will want to see

There is no UK list of qualifying conditions, so nothing here entitles you to a prescription. A specialist works through your history and decides whether a monitored trial is justified for you. For neuropathic pain they will typically look at:

• Whether your pain has been characterised as neuropathic, and what caused the nerve damage
• Which of amitriptyline, duloxetine, gabapentin and pregabalin you have tried, at what doses, and what happened
• Whether side effects rather than lack of effect were the reason you stopped
• Any underlying condition driving the pain — diabetes, MS, shingles, surgery, injury — and how it is being managed
• Your sleep, mood and daily function, not only your pain score
• Your personal and family history of psychosis, and your current mental health

The general requirements — age, a documented diagnosis, the convention that two standard treatments have been tried, and access to your medical records — are covered in What are the requirements?

Risks and reasons a specialist may say no

The Cochrane review's own conclusion is worth repeating: the potential benefits may be outweighed by the harms. Drowsiness, dizziness, confusion and impaired concentration are common, and are the usual reason people stop.

THC-containing products impair driving, and driving while impaired is an offence regardless of a prescription. A specialist will weigh a personal or family history of psychosis heavily, and will normally decline in pregnancy, breastfeeding, unstable serious mental illness or significant cardiovascular disease. If you also take sedating medicines, the combined effect matters more than either alone.

If you want to take this further

The useful next step is a proper assessment, not a better list. Gather your diagnosis, the treatments you have already tried and what happened with each, and your current medicines — that is what a specialist needs in order to give you a straight answer.

The consultation itself, and what happens after it, is set out in What is the process to get a medical cannabis prescription? If neuropathic pain is not the only thing you are being treated for, say so early: other conditions and other medicines change the assessment.
