Newly diagnosed? Here's what you actually need to know. No fluff — the essentials to keep you safe, in plain English.
Step 1
If you have a severe nut allergy, these go with you every single time you leave the house. No exceptions.
Always carry two. Not one. Two. If you have a severe reaction, you might need a second dose before emergency services arrive. Keep them in their original packaging, check expiry dates monthly, and replace them before they expire.
Carry non-drowsy antihistamines (like cetirizine or loratadine). These can help with mild reactions, but they are not a substitute for adrenaline in severe reactions.
A written plan from your GP or allergist that explains what to do in an emergency. Keep a copy on your phone and a physical copy in your wallet or bag.
Your GP's number, your allergist's number, and an emergency contact saved in your phone. Make sure someone close to you knows where your auto-injectors are and how to use them.
Pro tip: set a monthly phone reminder to check auto-injector expiry dates. Don't let them lapse.
Step 2
In the UK and EU, manufacturers must label the 14 major allergens, including nuts. Here's exactly what to do:
Nuts must be listed in bold or highlighted in the ingredients. Look for: almonds, brazil nuts, cashews, hazelnuts, macadamia, peanuts, pecans, pistachios, walnuts, or any product containing "nut" in the name.
Many products have a separate "Contains" or "Allergens" section. This is usually near the ingredients list and will clearly state if nuts are present.
Marzipan (almond paste), nougat (often almonds/hazelnuts), praline, nut oils, and unusual sources like Bombay Sapphire gin (filtered through almond shells) or pet food containing peanut butter/lupin.
If you can't be 100% certain a product is safe, don't eat it. Contact the manufacturer if you need clarification, or choose a different product.
Step 3
What it actually means: the product doesn't intentionally contain nuts, but it's made in a facility that also handles them. There's a real risk of cross-contamination during manufacturing.
It's a legal protection. Manufacturers use these warnings to protect themselves, but it doesn't mean the product is definitely unsafe — only that they can't guarantee it.
Your call. Many people with severe allergies avoid all "may contain" products. Others contact manufacturers about cleaning procedures. There's no one-size-fits-all answer — talk to your allergist.
Step 4
The most important decision you'll make. Get this one right.
If you're unsure whether to use it, use it. Seconds count.
Step 5
A written document telling you (and others) exactly what to do. Your GP or allergist should provide one — it should include your personal details, signs of a reaction by severity, step-by-step instructions for using your auto-injector and when to call 999, and emergency contacts.
Important: make sure family, friends, colleagues, and teachers know where your action plan is and how to use your auto-injector.

Your GP can refer you. An allergist can help you understand your specific risk level and create a personalised management plan.
Anaphylaxis UK and Allergy UK provide support, resources, and updates on product recalls.
Don't be shy about your allergy. Tell friends, family, colleagues, and anyone who might be preparing food for you.
Most auto-injectors come with a training device. Practice regularly so using it becomes second nature.
