If you are having a severe allergic reaction now, use your adrenaline pen and call 112 or 999. Anaphylaxis is a life-threatening allergic reaction, and emergency anaphylaxis treatment is adrenaline given by an auto-injector pen. If a doctor has already diagnosed your risk and prescribed pens before, you can request replacement or spare adrenaline pens online in Ireland for €25. You complete a secure questionnaire, a doctor registered with the Irish Medical Council reviews it, and if clinically suitable your prescription is sent to the Irish pharmacy you choose. If not, the doctor explains why and suggests next steps.
What is included
- A review of your medical questionnaire by an Irish Medical Council-registered doctor
- A prescription for replacement or spare adrenaline auto-injector pens, if clinically suitable
- Secure electronic delivery of the prescription to your chosen pharmacy in Ireland
- Written advice on carrying, storing and using your pens
- Secure messaging with the doctor about your request
The €25 fee covers the doctor's review. The cost of the medication is paid separately at your pharmacy.
Who this service is not suitable for
This service is only for people who already have a diagnosed risk of anaphylaxis. Our doctors cannot safely prescribe adrenaline pens online if you:
- have never been prescribed an adrenaline pen by a doctor before
- have a new allergy or a first allergic reaction, which needs a proper allergy assessment
- have had a reaction since your last review that was more severe or needed hospital treatment
- are requesting pens for a child, because the dose depends on body weight and must be set by the child's own doctor
- have asthma that is not well controlled, as this raises the risk of a severe reaction
- have symptoms of an allergic reaction right now (call 112 or 999)
If any of these apply, please book a video consultation with a GP or see your own GP so a doctor can assess you properly.
How it works
- Complete the questionnaire. Answer questions about your allergy diagnosis, previous reactions, your current pens and any medication you take. It takes about five minutes.
- Doctor review. An Irish-registered doctor reviews your answers against clinical guidance and may message you if more information is needed.
- Prescription sent. If treatment is suitable, the prescription is sent securely by Healthmail to the Irish pharmacy you choose, ready for you to collect.
What is anaphylaxis?
Anaphylaxis happens when the immune system overreacts to a trigger and releases large amounts of histamine and other chemicals. It usually develops within a few minutes but can take longer. It affects the airway, breathing or circulation, and may come with a rash, hives or swelling, although skin symptoms are not always present.
Signs of anaphylaxis
- swelling of the throat or tongue, difficulty swallowing or a hoarse voice
- difficulty breathing, wheeze, a persistent cough or noisy breathing
- feeling faint or dizzy, pale and clammy skin, confusion or collapse
Common triggers
Common triggers include foods such as peanuts, tree nuts, shellfish, fish, milk and eggs, wasp and bee stings, some medicines and latex. Exercise or alcohol can sometimes make a reaction more likely in people who are already allergic.
Anaphylaxis treatment options
Adrenaline works quickly to open the airways, raise blood pressure and reduce swelling. An adrenaline auto-injector delivers a measured dose into the muscle. Antihistamines and inhalers can ease milder symptoms but do not replace adrenaline in anaphylaxis.
Carrying and storing your pens. Carry two pens with you at all times, because a second dose may be needed. Check the expiry date regularly and replace pens before they expire. Store them at room temperature, out of direct sunlight, and never in the fridge or a hot car. If your device has a viewing window, check the liquid is clear.
How to use an adrenaline pen. Devices differ, so read the instructions on your own pen and practise with a trainer device if one is available. In general:
- Remove the safety cap as shown on your device.
- Press the tip firmly into the outer thigh. You can inject through clothing.
- Hold it in place for the time stated on your device, then remove it.
- Call 112 or 999 and say "anaphylaxis", even if you start to feel better.
Lie down with your legs raised, or sit up if breathing is difficult. Do not stand or walk, even if you feel better. If there is no improvement after five minutes, use the second pen. Always go to hospital after using a pen, because symptoms can return hours later.
Side effects and safety
Adrenaline can cause a fast or pounding heartbeat, shaking, paleness, anxiety and headache. These effects are short-lived. If you are unsure whether a reaction is anaphylaxis, use the pen: the risk of not using it is far greater than the side effects. If you accidentally inject into a finger, thumb or hand, seek urgent medical help.
When to see a doctor in person
See your GP or allergy clinic after any reaction where you needed to use your pen, if your reactions are changing, or if you have not had an allergy review in the last year. Your doctor can update your allergy action plan and refer you to an allergy specialist if needed. You can also meet our Irish-registered doctors or see all online prescription services.
