New Adrenaline Auto Injector in Development – AllergyStop

AllergyStop Adrenaline auto injector

AllergyStop is a newly designed adrenaline auto injector. The AllergyStop adrenaline auto injector is a palm sized injector that can be clipped to a keyring or belt loop.

Dr. Doug McMahon, a doctor from Minnesota that suffers from allergies developed the new auto injector in response to the fact that less than half of those who have an adrenaline pen carry it with them.

The AllergyStop device is customisable to the specific needs of each person. They use a BMI to make sure the allergic person is getting the right needle length and the right dose.


Adrenaline Auto Injector: Needle length

Currently, auto injectors have only one needle length. This is fine for people with a healthy weight, but for those who are overweight, it can mean that the adrenaline is being administered subcutaneously (underneath the skin) instead of intramuscularly. Intramuscular injection means that the adrenaline gets to work faster. The Allergystop auto injector can customise the needle length for the individual.

Adrenaline Dose

The recommended dose for adrenaline is 0.01mg per kilogram of body weight. The current injectors come in two doses, child and adult. The child dose is 0.15mg, and the adult dose is 0.30mg. Up to 0.5mg can be given as an adult dose which means that two adrenaline pens may need to be given. The 0.15mg dose for a child means that a child of under 15kg may receive too large a dose. The AllergyStop auto injector can be customised to the individual dose needed based on their body weight.

Carry Case

The AllergyStop auto injector comes in a small carry case that comes in many different colours. The case has a key ring to attach it to keys, belts and bags.


The AllergyStop would be available through your doctor. Your doctor must submit the application on your behalf in order to get the AllergyStop auto injector customised to your needs.

AllergyStop is currently awaiting FDA approval.
