Jext, EpiPen, Neffy and Nyxoid: What First Aid Trainers and Workplaces Should Know

Emergency medication devices are becoming more common in Australian workplaces, schools, childcare centres, community organisations and first aid training environments. For many years, EpiPen has been one of the most recognised devices for anaphylaxis. However, other devices such as Jext and Neffy are now also part of the conversation in Australia.

Nyxoid is also increasingly discussed in first aid and community health settings, but it is used for a different emergency: suspected opioid overdose.

For first aid trainers, RTOs, workplaces and community organisations, it is important to understand the difference between these devices, what they are used for, and why regular training with demonstration devices matters.

This article is general education only and is not a substitute for medical advice, product instructions, ASCIA Action Plans, workplace procedures or emergency services guidance. In an emergency, call 000.

What is anaphylaxis?

Anaphylaxis is a severe and potentially life-threatening allergic reaction. It can happen quickly and may involve breathing difficulty, swelling of the tongue or throat, wheeze, persistent dizziness, collapse, or symptoms affecting more than one body system.

Common triggers may include:

  • Foods such as peanuts, tree nuts, shellfish, milk or egg
  • Insect stings or bites
  • Medicines
  • Latex
  • Unknown triggers in some cases

Adrenaline, also called epinephrine, is the first-line emergency treatment for anaphylaxis. People at risk of anaphylaxis may be prescribed an adrenaline device and should follow their ASCIA Action Plan or individual medical advice.

EpiPen: the well-known adrenaline auto-injector

EpiPen is one of the most recognised adrenaline auto-injectors in Australia. It contains a single dose of adrenaline and is designed for emergency use during anaphylaxis.

EpiPen trainer devices are commonly used in first aid courses, schools, childcare centres and workplace training. These trainer devices do not contain a needle or medication. They are designed to help learners practise the correct technique safely and repeatedly.

Training with an EpiPen trainer can help people become more confident with:

  • Recognising when an adrenaline device may be needed
  • Positioning the device correctly
  • Understanding the basic sequence of use
  • Practising emergency response steps in a calm learning environment

Confidence matters because hesitation during anaphylaxis can delay treatment.

Jext: another adrenaline auto-injector option in Australia

Jext is another adrenaline auto-injector used for the emergency treatment of anaphylaxis. Like EpiPen, it is a single-use device that delivers adrenaline.

As more people become prescribed or supplied with different adrenaline devices, first aid trainers and workplaces may start seeing Jext more often.

This is important because not all adrenaline devices look or operate exactly the same. A person who has only practised with one type of trainer may feel unsure when presented with a different device in a real emergency.

For training providers, workplaces and education settings, it may be useful to include more than one type of adrenaline trainer device in practical sessions. This helps learners understand that the core emergency principle remains the same: follow the action plan, give adrenaline when indicated, call 000, and continue monitoring the person.

For anaphylaxis awareness sessions, school programs, workplace refreshers and first aid training rooms, Enzo Medix supplies the Jext Trainer Pen for First Aid Training. This is a training and demonstration product only and is not for medical treatment or emergency use.

neffy: needle-free adrenaline nasal spray

neffy is an adrenaline nasal spray for the emergency treatment of anaphylaxis. Unlike EpiPen and Jext, neffy does not use a needle. It delivers adrenaline through a nasal spray device.

This is a significant development because needle fear can be a barrier for some people. A needle-free option may make emergency treatment feel less intimidating for some patients, carers and responders.

However, neffy is still an emergency adrenaline device. It should be used according to the prescribed instructions, ASCIA guidance, product information and the person’s action plan. After giving adrenaline, emergency medical care is still required.

For first aid training, neffy introduces a new practical consideration: learners may now need awareness of both auto-injectors and nasal adrenaline devices. Training should avoid assuming that every anaphylaxis device will be an EpiPen-style injector.

For nasal spray emergency response education, Enzo Medix supplies a Nasal Spray Trainer for First Aid Training. This can support classroom discussion and practical familiarisation around nasal spray-style emergency devices.

EpiPen vs Jext vs neffy: what is the main difference?

EpiPen, Jext and neffy are all adrenaline devices used for anaphylaxis, but they differ in design and method of delivery.

  • EpiPen is an adrenaline auto-injector.
  • Jext is an adrenaline auto-injector.
  • neffy is a needle-free adrenaline nasal spray.

EpiPen and Jext are generally used on the outer mid-thigh and are designed to deliver adrenaline by injection. neffy is administered into the nostril.

The most important training message is that people should know the device they have been prescribed or supplied, practise with the correct trainer where available, and follow current Australian guidance.

In a workplace, school or community setting, it is also helpful to make sure emergency plans are clear, devices are stored appropriately, expiry dates are checked, and staff know where devices and action plans are located.

What is Nyxoid?

Nyxoid is different from EpiPen, Jext and neffy.

Nyxoid contains naloxone, not adrenaline. It is used for the emergency treatment of suspected opioid overdose. Opioids may include medicines such as morphine, oxycodone, fentanyl, methadone or heroin.

Nyxoid is a nasal spray device. It is designed to temporarily reverse the effects of opioid overdose, particularly breathing depression. Emergency services should still be called immediately, because naloxone may wear off and the person can become unwell again.

Signs of suspected opioid overdose may include:

  • Slow, irregular or absent breathing
  • Unresponsiveness
  • Blue or grey lips or fingertips
  • Pinpoint pupils
  • Gurgling or snoring sounds
  • Limp body

Nyxoid is increasingly relevant in first aid, community care, health, social support, security and public-facing workplace settings. Like adrenaline devices, practical awareness and training can improve confidence during a real emergency.

Because Nyxoid is also a nasal spray-style emergency device, a nasal spray trainer can be useful for general first aid education and device familiarisation. Always follow the relevant course requirements, workplace procedures, product instructions and emergency guidance.

Why trainer devices matter

Trainer devices are an important part of first aid education because they allow people to practise without medication or needles.

For first aid trainers and RTOs, demonstration devices can help learners build confidence before they are faced with a real emergency. For workplaces, they can support staff refreshers and emergency preparedness sessions.

Training devices may be useful for:

  • First aid courses
  • CPR and anaphylaxis refreshers
  • Childcare and school staff training
  • Disability and community support workers
  • Workplace emergency response teams
  • Health and aged care education
  • Public access emergency response training

The goal is not just to show the device once. The goal is to help people feel confident enough to act quickly and correctly when it matters.

For practical classroom demonstrations, Enzo Medix supplies a range of CPR and First Aid Training Supplies, including the Jext Trainer Pen, Nasal Spray Trainer for First Aid Training, and Asthma Placebo Inhaler for First Aid Training.

Training considerations for workplaces and first aid providers

If your workplace, school or training organisation includes anaphylaxis or overdose response in its emergency planning, consider the following:

1. Keep emergency plans up to date

Make sure action plans, first aid procedures and emergency response instructions are current and easy to access.

2. Check expiry dates

Medication devices have expiry dates. Workplaces should have a process for checking and replacing expired devices.

3. Store devices correctly

Follow the manufacturer’s storage instructions. Avoid exposing devices to excessive heat, cold or direct sunlight.

4. Train with the right device

If staff may encounter EpiPen, Jext, neffy or Nyxoid, training should reflect the devices they are most likely to see.

5. Call 000 in an emergency

Adrenaline and naloxone are emergency treatments, but they do not replace emergency medical care.

6. Refresh training regularly

Skills and confidence fade over time. Regular refreshers help people stay prepared.
