EURneffy 2mg nasal spray is a prescription-only, needle-free adrenaline nasal spray licensed in the UK for the emergency treatment of anaphylaxis in adults and children weighing 30kg or more.
Each single-dose container delivers 2mg of adrenaline in 100 microlitres. Prescribed and dispensed in the UK by Courier Pharmacy with personalised online consultation, training guidance, GPhC-registered pharmacist oversight, and discreet home delivery.
EURneffy 2mg nasal spray is a ready-to-use, single-dose adrenaline (epinephrine) nasal spray for the emergency treatment of anaphylaxis. Each device delivers 2mg adrenaline in 100 microlitres of a clear solution (colourless to pink-brownish).
You use EURneffy by placing the nozzle into one nostril and pressing the plunger. The device releases the full dose in one spray. There’s no priming step, and you don’t need to inhale. So, it’s designed to be simple to use in a high-stress emergency.
. The MHRA approved EURneffy on 18 July 2025, which made it the first needle-free adrenaline option for anaphylaxis available in the UK. It’s now available on prescription.
For many people, a needle-free format can remove a real barrier to giving adrenaline quickly. EURneffy also offers a longer shelf life than many auto-injectors. It has a 30-month shelf life and can tolerate temperature excursions up to 50°C. By comparison, many injectable devices have a shorter shelf life and lower temperature limits.
However, EURneffy doesn’t automatically replace your auto-injector. Your allergy specialist should decide the safest plan for you. In other words, some people may carry both, or carry EURneffy alongside an EpiPen or Jext.
A lower-dose 1mg version for children weighing 15–30kg is approved in the US and is under review in Europe. So, UK availability for that dose may follow, but timing can vary.
We supply EURneffy 2mg nasal spray through Courier Pharmacy, a UK GPhC-registered pharmacy. If you have questions about storage, expiry dates, or how to use it, our pharmacy team can help.

The moment your throat starts to swell after eating something at a restaurant. The reaction that hits in the back of a taxi after a wasp sting. The first sign of anaphylaxis arriving faster than you can process. For decades, the only way to give yourself adrenaline in that moment has been a needle-bearing auto-injector, which works brilliantly but can feel daunting in the seconds when you need it most.
EURneffy 2mg nasal spray is the first needle-free option approved in the UK, delivering a single 2mg dose of adrenaline through the lining of one nostril. At Courier Pharmacy, we believe healthcare should fit you, not the other way round. Whether you’ve been needle-phobic since childhood, are caring for an older parent with severe allergies, or are looking for MCAS care that takes you seriously and acknowledges the reality of anaphylaxis risk, this page is here to help.
Five key takeaways
EURneffy 2mg nasal spray is the first needle-free adrenaline (epinephrine) treatment for anaphylaxis approved by the MHRA in the UK, authorised on 18 July 2025.
It delivers a single 2mg dose of adrenaline in 100 microlitres into one nostril and is licensed for adults and children weighing 30kg or more.
Patients should always carry two devices, since a second dose in the same nostril is recommended after 5 minutes if symptoms continue or worsen.
EURneffy supplements rather than replaces existing adrenaline auto-injectors; emergency services (999) must still be called every time it’s used.
Courier Pharmacy supplies EURneffy through online prescriber consultation with personalised counselling, full pharmacist oversight, and free fortnightly community clinics in Derby.
Treatment dosage EURneffy 2mg nasal spray
The recommended dose is a single nasal administration of 2mg of adrenaline. At the first sign of anaphylaxis, insert the nozzle into one nostril until your fingers touch your nose and press the plunger firmly until it snaps up. The device delivers its full 2mg dose in one spray.
Don’t sniff during or after administration, since sniffing may reduce absorption. After using the spray, dial 999 immediately, regardless of whether you feel better. Anaphylaxis can rebound or progress unpredictably, and you need to be monitored by emergency services.
If symptoms continue, return, or worsen after 5 minutes (or if there has been any error in administering the first dose), use a second EURneffy nasal spray in the same nostril as the first.
The licensed maximum without medical supervision is two doses (4mg total). This is why patients prescribed EURneffy should always carry two devices, just as auto-injector users carry two pens. The same posology applies to children weighing 30kg or more.
Position matters in anaphylaxis. Ideally, lie flat with your feet slightly elevated to support blood pressure. People with breathing difficulty can gently sit up, but should return to lying down as soon as possible. Pregnant women should lie on the left side. Don’t stand up suddenly even if symptoms appear to settle, since standing can cause rapid cardiovascular collapse (the so-called empty ventricle phenomenon). Stay lying down until emergency services arrive.
Overview of EURneffy 2mg nasal spray
A UK-licensed needle-free adrenaline nasal spray for emergency anaphylaxis treatment
Delivers 2mg of adrenaline in a single nasal dose; absorbed through the nasal lining
Licensed for adults and children weighing 30kg or more
Should be used alongside (or sometimes instead of) auto-injectors as part of an individualised emergency plan
Available from Courier Pharmacy through online prescriber consultation and pharmacist-led training
Anaphylaxis is a sudden, severe allergic reaction that can be life-threatening within minutes. Around 1-2% of the UK population is at risk, with food allergies (particularly peanuts, tree nuts, milk, eggs, shellfish), insect stings, medications and (less commonly) exercise or unknown triggers being the most frequent causes. Adrenaline is the only definitive emergency treatment; it raises blood pressure, opens the airways, and dampens the immune cascade driving the reaction.
Until July 2025, the only way to self-administer adrenaline in the UK was through an auto-injector device like EpiPen or Jext. These work well, but real-world studies have repeatedly shown that fear of using the needle, uncertainty about technique, and the bulk of the device can lead to delayed administration. Delay matters: every minute counts in anaphylaxis. The needle-free format of EURneffy removes one of the more common psychological barriers to acting quickly.
Practical advantages beyond needle-free administration are worth noting. The device is more temperature-stable than auto-injectors, with a 30-month shelf life and tolerance for excursions up to 50°C (compared with 12-18 months and 30°C for most injectable products). This makes it more forgiving in summer heat, in hot cars, or in countries with less reliable refrigeration. The compact form factor (similar to a hand sanitiser spray) is also easier to carry in slim handbags and pockets where a full-size auto-injector might not fit, which can increase the likelihood that people actually have their adrenaline with them when they need it.
It’s worth being honest about what EURneffy isn’t. It isn’t a replacement for clinical anaphylaxis management. Even after a successful nasal dose, you must call 999 and be monitored for biphasic reactions (a second wave of symptoms that can occur hours after the initial reaction). It isn’t suitable for children weighing under 30kg until the 1mg version becomes available in the UK. And it isn’t a reason to stop carrying auto-injectors if your specialist hasn’t agreed to the switch.
Many of our patients arrive after years of being handed prescriptions for auto-injectors with minimal training or follow-up. We don’t subscribe to that approach for a medicine where the difference between correct and incorrect use could be a different outcome. Whether you’re navigating food allergies, MCAS care that takes you seriously, idiopathic anaphylaxis, fibromyalgia overlap with mast cell symptoms, or chronic illness support that fits your life, the goal is a personalised plan you actually feel confident with.
Why choose Courier Pharmacy for EURneffy 2mg nasal spray
We started Courier Pharmacy because too many people were being handed prescriptions for emergency medicines with the briefest of explanations, no demo device, and no follow-up. For a treatment like EURneffy, where confident use under pressure could shape an outcome, that isn’t good enough. Personalisation means looking at your specific anaphylaxis pattern, your other medicines, your wider health context, and your relationship with auto-injectors, then deciding together whether EURneffy is the right fit, the right partner to an existing auto-injector, or whether specialist input is needed first.
Guidance carries through after the prescription is issued. Our GPhC-registered pharmacists are reachable for the smaller questions that often go unasked: am I using this correctly? Do I really need to call 999 every time? What if I’m pregnant and it happens? Our medical lead, the figure behind much of our clinical thinking, is Dr Ada Jex-Cori, an evidence-led, community-rooted clinician who built her practice on the belief that people in high-stakes health situations deserve to be heard and prepared, not just prescribed. MCAS care that takes you seriously is central to that ethos.
Trust is the part that has to be earned, not claimed. We’re a UK-regulated pharmacy, we publish our processes, we tell you when something isn’t suitable, and we’ll always refer you to your immunologist or allergist if your situation warrants specialist oversight rather than a prescription from us alone. We’d rather lose a sale than place an emergency medicine where it doesn’t belong. Whether you’re navigating food allergies, idiopathic anaphylaxis, MCAS care, fibromyalgia support with mast cell overlap, or chronic illness care that fits your life, we’ll meet you where you are.

If it isn’t suitable for you, we’ll explain why and suggest the next best option. Sometimes that’s referral to a specialist allergy clinic, sometimes it’s a different adrenaline product, sometimes it’s a conversation about whether your current auto-injector plan needs reviewing. We also run free fortnightly drop-in clinics and talks at Insomnia, Derby, 12 to 1pm. No appointment, no cost, no obligation.
Active ingredient in EURneffy 2mg nasal spray
The active ingredient is adrenaline (epinephrine), 2mg per single-dose container. Adrenaline is a hormone produced naturally by the adrenal glands in response to stress, and it's the body's own emergency response chemical. When given exogenously during anaphylaxis, adrenaline acts on alpha-adrenergic receptors to raise blood pressure and reduce swelling, and on beta-adrenergic receptors to open the airways, increase heart rate and reduce the release of further inflammatory mediators from mast cells . The combined effect can reverse the cardiovascular collapse and airway obstruction of anaphylaxis within minutes.
EURneffy's formulation also contains benzalkonium chloride (40 micrograms per dose), sodium metabisulfite (5 micrograms), dodecyl maltoside (a permeation enhancer that helps the adrenaline cross the nasal lining quickly), edetate disodium, hydrochloric acid, and water for injections. Sodium metabisulfite can rarely cause allergic-type reactions in susceptible people, but in the context of life-threatening anaphylaxis, the benefit of giving adrenaline is enormously greater than the risk of this hypersensitivity. The pharmacokinetic profile shows adrenaline plasma concentrations after a 2mg nasal dose that are within the overall range of those seen after a 0.3mg intramuscular adrenaline injection (the EpiPen standard adult dose).
What is EURneffy 2mg nasal spray for?
EURneffy 2mg nasal spray is licensed for the emergency treatment of anaphylaxis caused by insect stings or bites, foods, medicinal products, or other allergens, as well as idiopathic anaphylaxis (where no trigger can be identified) and exercise-induced anaphylaxis. It's approved for adults and children weighing 30kg or more.
Anaphylaxis can present in many ways, but the key features include sudden onset and rapid progression of one or more of: difficulty breathing or wheeze, swelling of the tongue, lips, throat or face, hoarse voice or stridor, severe abdominal pain or vomiting, a sudden drop in blood pressure (often with dizziness or collapse), and widespread urticaria or angioedema. Skin symptoms alone aren't enough to diagnose anaphylaxis; the systemic features are what define it. If you're at risk, work through the symptom pattern with your specialist so you know what to act on.
EURneffy is not licensed for asthma attacks (which need salbutamol and steroids), for milder allergic reactions like hives without systemic features, or for treating angioedema not driven by allergic mechanisms (hereditary angioedema, for instance, needs different treatments). It's also not suitable for children under 30kg until the paediatric 1mg version becomes available in the UK. A note on chronic illness contexts: people with MCAS, hereditary alpha-tryptasemia, or systemic mastocytosis often have anaphylaxis risk that needs specialist input, and we'll always recommend liaison with your immunologist or allergist when prescribing EURneffy in that context. Our team can support that conversation rather than working around it.

How to use EURneffy 2mg nasal spray
At the first sign of anaphylaxis, don't wait to be sure. Use EURneffy. Hold the device with your thumb on the base and two fingers either side of the nozzle. Insert the nozzle into one nostril until your fingers touch the outside of your nose. Hold the device straight into the nose, pointed slightly toward your forehead, not angled toward the inner wall (the septum) or the outer wall of the nostril. Press the plunger firmly until it snaps up. You'll feel the spray release. Don't sniff during or after.
Position yourself to support your circulation. Lie flat with your feet slightly raised, unless you're struggling to breathe, in which case sit up slightly while still leaning back. Pregnant women should lie on the left side to take pressure off the major blood vessels. Don't stand up. Don't walk. Call 999 immediately or have someone with you call. Tell the operator you're using adrenaline for anaphylaxis. Stay where you are until paramedics arrive, even if symptoms appear to be settling.
Practical tips from our pharmacists: practise the technique with a demo device (your prescriber can arrange one) before you need it for real; carry two devices everywhere, since one may not be enough; tell people close to you (family, friends, colleagues, school staff) how to use the spray and where you keep it; replace devices before their expiry date even if unused; and never store EURneffy in a freezer, since a frozen device will not deliver adrenaline (allow at least one hour to thaw at room temperature if accidentally frozen, and discard if the contents look frozen or partly frozen). Keep one device at home and one with you at all times rather than splitting your pair geographically.
Warnings and precautions for EURneffy 2mg nasal spray
EURneffy has no listed contraindications, because in the context of a life-threatening allergic reaction, the benefit of giving adrenaline almost always outweighs the theoretical risks. However, several precautions apply. People with cardiovascular disease (ischaemic heart disease, coronary artery disease, arrhythmias, severe hypertension, cardiomyopathy) are more vulnerable to adrenaline-related side effects such as raised blood pressure and arrhythmias. This doesn't stop them from using EURneffy in an emergency, but it makes the conversation with a specialist about whether nasal or intramuscular adrenaline is the better fit more important.
Hyperthyroidism, Parkinson's disease, diabetes, renal impairment, and low blood potassium can all be temporarily worsened by adrenaline, so people with these conditions should be carefully assessed. People with significant structural or anatomical nasal problems (severe deviated septum, post-surgical changes, large polyps, recent nasal trauma) may have unpredictable absorption from a nasal spray, and an auto-injector may be the safer first-line in that situation. Tell your prescriber about any of these factors during the consultation.
Patient training matters more for EURneffy than for many medicines. Because anaphylaxis is rare for individual patients but high-stakes when it happens, regular practice with a demo device is genuinely important. Studies show that even experienced users of auto-injectors make technique errors under pressure; a needle-free device removes one source of error but doesn't eliminate the need to practise. Our team will ensure you have access to a demo device and clear written and video instructions, and we'll encourage you to share these with family members.
Pregnancy and breastfeeding are usually not barriers to using EURneffy when needed. There's no clinical data specifically in pregnant women, but adrenaline has been used in pregnancy for anaphylaxis for decades, and the consensus is that the risk of untreated anaphylaxis to mother and baby far outweighs the theoretical risk of the medicine. EURneffy can be used in breastfeeding women because adrenaline has poor oral bioavailability and a very short half-life, so transfer to the infant via breast milk is minimal.
A common misunderstanding: EURneffy doesn't replace your existing auto-injector unless your specialist explicitly switches you over. For many people with anaphylaxis risk, the right plan is to carry one EURneffy alongside one auto-injector, giving you a needle-free option you'd reach for first and a backup if needed. Discuss the right combination with your immunologist or allergist.
Side effects of EURneffy 2mg nasal spray
The most frequently reported adverse reactions in clinical trials of EURneffy 2mg (only after a second 4mg total dose) included throat irritation (18.8%), headache (17.6%), nasal discomfort (12.9%) and feeling jittery (10.6%). None of these were considered serious. These are exactly the side effects you would expect from giving a strong dose of adrenaline, regardless of the route, since adrenaline is by nature a stimulant.
Common (occurring in 1-10% of users) side effects after a single 2mg dose include anxiety, tremor, palpitations, runny nose (rhinorrhoea), nasal swelling (nasal oedema), nasal pain (rhinalgia), nasal congestion, increased blood pressure, and increased heart rate. Most of these are short-lived and reflect adrenaline's expected pharmacology rather than a hypersensitivity to the medicine itself.
Less common and rare effects can include chest discomfort, sweating, nausea or vomiting, weakness, dizziness, pale skin (pallor), and feelings of agitation or impending doom (a documented effect of adrenaline that doesn't reflect a real threat). Very rarely, serious adrenergic effects can occur, including ventricular arrhythmias in people with underlying heart disease, hypertensive crisis, or cerebral haemorrhage from a sharp rise in blood pressure. These are most likely when adrenaline is given to someone with significant pre-existing cardiovascular disease.
Overdose is unlikely with a single 2mg dose but possible if multiple doses are given in succession without medical supervision. Symptoms can include severe headache, chest pain, dizziness, nausea, blurred vision, and significant rises in blood pressure. If you have used more than two doses (4mg) of EURneffy outside of a hospital setting, call 999 and inform the emergency services. Continued monitoring will usually be necessary.
Suspected side effects can and should be reported to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. EURneffy is a recently approved product, so post-marketing surveillance is particularly important; reporting helps build the safety picture for everyone.
Drug interactions with EURneffy 2mg nasal spray
Several medicines can interact with adrenaline. Tricyclic antidepressants (amitriptyline, nortriptyline), monoamine oxidase inhibitors, levothyroxine, certain antihistamines, and some Parkinson's medicines (levodopa) can intensify the effects of adrenaline. In emergency anaphylaxis treatment this rarely changes the decision to give adrenaline, but it can mean side effects are more pronounced.
Beta-blockers (propranolol, bisoprolol, metoprolol, atenolol) can blunt the response to adrenaline, since they block the beta-adrenergic receptors that adrenaline acts on. People on beta-blockers may need a second dose more often, and they may also be more prone to alpha-adrenergic side effects like raised blood pressure once the beta-blockade has been overcome. If you're on a beta-blocker for cardiovascular disease, mention this clearly during the consultation; sometimes the medicine can be reviewed and switched to something with less impact on adrenaline response.
Diuretics and other medicines that lower potassium can be exacerbated by adrenaline, which itself can lower potassium briefly. This rarely matters acutely but can be relevant in people with cardiac conditions. ACE inhibitors and angiotensin receptor blockers don't directly interact with adrenaline but can complicate anaphylaxis treatment because they affect the blood pressure regulation systems the body would normally use to compensate.
Other nasal sprays applied around the same time can affect EURneffy's absorption, although in a real anaphylaxis emergency the nasal spray takes priority and any concurrent nasal medication is irrelevant. Diabetic patients on insulin or oral hypoglycaemics may need to monitor blood glucose after using adrenaline, since adrenaline raises blood glucose temporarily. None of these interactions are reasons to avoid EURneffy in anaphylaxis; they're reasons to discuss the bigger medication picture during your consultation.
Alcohol doesn't pharmacokinetically interact with adrenaline, but heavy intoxication can complicate any emergency medical situation. There are no relevant interactions with the contraceptive pill, statins, common antibiotics, or most other regular medications. As always, give us a complete medicines list during your consultation so we can be sure.
Frequently asked questions about EURneffy 2mg nasal spray
What is EURneffy 2mg nasal spray used for?
EURneffy 2mg nasal spray is licensed for the emergency treatment of anaphylaxis caused by insect stings or bites, foods, medicines, other allergens, and idiopathic or exercise-induced anaphylaxis. It's approved for adults and children weighing 30kg or more and offers a needle-free alternative to adrenaline auto-injectors.
How quickly does EURneffy 2mg nasal spray work?
Adrenaline begins to act within 1 to 5 minutes of nasal administration. Plasma adrenaline levels reached after a 2mg nasal dose are within the range of those produced by a 0.3mg intramuscular injection (the standard adult EpiPen dose). Effects last 5 to 20 minutes, which is why a second dose may be needed and why 999 must always be called.
Does EURneffy 2mg nasal spray replace my EpiPen or Jext?
Not automatically. EURneffy is an alternative or complement to auto-injectors, depending on what your specialist recommends. For some people the switch is sensible; for others, carrying one of each (or a pair of one and a single backup of the other) is the safer plan. Discuss with your immunologist or allergist before changing your emergency kit.
Why should I carry two EURneffy 2mg nasal spray devices?
A second dose is recommended if symptoms continue or worsen 5 minutes after the first dose, in the same nostril as the first. Around 10-20% of anaphylaxis episodes need a second dose to control symptoms. Carrying two devices means you're prepared for that scenario, just as auto-injector users carry two pens.
Does EURneffy 2mg nasal spray work if I have a blocked nose?
Yes. Clinical trials specifically tested EURneffy in people with allergic rhinitis and seasonal nasal congestion, and adrenaline absorption was preserved. This was an important question during development because nasal allergy is common among anaphylaxis-prone patients. A streaming or congested nose isn't a reason to avoid EURneffy.
Should I still call 999 after using EURneffy 2mg nasal spray?
Yes, every time, even if you feel better. Anaphylaxis can rebound (biphasic reactions occur in around 1-20% of cases), and ongoing monitoring is essential. Adrenaline's effects only last 5 to 20 minutes; the underlying allergic cascade can persist for hours. Call 999, tell them you've used adrenaline for anaphylaxis, and stay where you are.
Can children use EURneffy 2mg nasal spray?
EURneffy 2mg is licensed for children weighing 30kg or more. Children weighing 15-30kg will need the 1mg version, which is approved in the US and under European review, with UK availability expected later. Children under 15kg need other formulations of adrenaline. Discuss paediatric anaphylaxis with a paediatric allergy specialist.
Can I use EURneffy 2mg nasal spray during pregnancy?
Yes, when needed. There's no specific clinical data in pregnant women, but adrenaline has been used in pregnancy for anaphylaxis for decades. The risk of untreated anaphylaxis to mother and baby vastly outweighs the theoretical risk of treatment. During administration, pregnant women should lie on the left side to support blood flow.
Is EURneffy 2mg nasal spray safe while breastfeeding?
Yes. Adrenaline has poor oral bioavailability (so any small amount in breast milk wouldn't be absorbed by the baby) and a very short half-life. Breastfeeding can continue normally after using EURneffy in an emergency. The infant doesn't need separation from the mother because of the medication itself.
How is EURneffy 2mg nasal spray different from injectable adrenaline?
EURneffy delivers adrenaline through the nasal lining; auto-injectors deliver it into the thigh muscle. Plasma levels after a 2mg nasal dose match those after a 0.3mg intramuscular injection. The main practical differences are the needle-free administration, longer shelf life (30 months vs 12-18), better temperature tolerance, and smaller form factor.
How should I store EURneffy 2mg nasal spray?
Store at room temperature (below 25°C ideally). Excursions up to 50°C are permitted, which makes EURneffy more forgiving in summer or in hot countries than most auto-injectors. Do not freeze; if accidentally frozen, allow at least one hour to thaw at room temperature, and discard if the contents look frozen or partially frozen. Freezing doesn't reduce shelf life if the device thaws properly.
What if I take a beta-blocker?
Beta-blockers can blunt the response to adrenaline, since they block one of its key receptor pathways. People on beta-blockers may need a second dose more often. This doesn't stop you from using EURneffy in an emergency, but it can mean reviewing the beta-blocker if a less-interfering option is available. Mention beta-blockers clearly during your consultation.
Can people with MCAS use EURneffy 2mg nasal spray?
Yes, and many specialists actively recommend it for MCAS patients with anaphylaxis risk. The needle-free format is particularly valued by people who have multiple episodes per year and who may struggle psychologically with repeated injections. We always review the full ingredient list during your consultation if you have known mast cell reactivity to excipients like sodium metabisulfite.
What if I have a deviated septum or nasal surgery history?
Significant structural or anatomical nasal problems can affect adrenaline absorption from EURneffy. For severe deviation, large polyps, or recent nasal surgery, an auto-injector may be the safer first-line option. Mention any nasal conditions or surgical history during your consultation so the prescriber can make a personalised recommendation.
Can I practise using EURneffy 2mg nasal spray before I need it?
Yes, and you should. A trainer device (containing no adrenaline) is available so you can practise the technique without using a real EURneffy. We strongly recommend ordering a demo device alongside your prescription and practising several times. Family members, partners, school staff or carers should also practise so they can help if you're unable to administer it yourself.
What happens if I use EURneffy 2mg nasal spray but I didn't actually have anaphylaxis?
You may experience some adrenergic effects (raised heart rate, palpitations, tremor, anxiety, headache) for 10 to 30 minutes, but no long-term harm is likely. Adrenaline is a fast-clearing hormone. If you're unsure whether you have anaphylaxis, current guidance is to use the spray rather than wait; the risk of giving adrenaline unnecessarily is far smaller than the risk of withholding it during a real episode.
How long does EURneffy 2mg nasal spray stay effective?
EURneffy has a 30-month shelf life from manufacture, which is significantly longer than the 12-18 months of most adrenaline auto-injectors. Check the expiry date on each device and replace before it expires, even if unused. Don't try to use expired EURneffy; adrenaline degrades over time and an expired device may not deliver an effective dose.
Can EURneffy 2mg nasal spray be used by an older adult?
Yes. No dose adjustment is required for older adults (aged 65 or over). However, older adults are more likely to have cardiovascular conditions that warrant a careful conversation about which adrenaline format is the best fit. Pharmacokinetic data in this age group is limited, but clinical use is appropriate when anaphylaxis is suspected.
Will EURneffy 2mg nasal spray be covered on the NHS?
EURneffy is licensed and available on UK prescription. NHS availability depends on local formulary decisions, which can take time after MHRA approval. For now, many patients access EURneffy via private prescription. Discuss NHS availability with your GP or allergist; we can supply privately if you'd prefer not to wait for formulary inclusion in your area.
