Redesigning EpiPen

Redesigning an analog device into a digital experience


I was asked by one of my professors to pull out an analog device from our backpacks, and mine was my EpiPen. We were tasked to solve the issues with the interface so it can meet users needs. Initially, I didn't see too many problems until I started to look closer. I realized that the medicine had been expired for two years.  My first thoughts were - How could I have not have known this? What would've happened if I had an allergic reaction and used expired medicine? Why was I not alerted? This began my process of redesigning an EpiPen.



EpiPen is an auto-injector for people who have a history of minor to sever allergic reactions. EpiPen injectors are the most common perscribed epinephrine in the United States for more than 25 years. Using an EpiPen is the first step to use when having an allergic reaction and then going to the hospital immediately. 

After reading more, I found it astonishing that there haven't been any updates for the experience when users are having an allergic reaction. Depending on the severity of the reactions, users are not able to see or hear due to the intense shock in their bodies. So finding a solution was vital for me to feel like I could contribute a possible solution to a awful experience users go through when having an allergic reaction.



Finding a solution to the an analog experience for users that use an EpiPen during severe allergic reactions.

Below are some initial concepts of sketching and process issues I wanted to resolve. The biggest issues I noticed were noticing medicine discoloration, alerting medical contacts of use, and disposing of the medicine. This is the experience I wanted to highlight. I decided that changing the design of the case would be the biggest issue to focus on then pairing the experience with an app. Redesigning the case would allow users to understand when medicine is ready to use and would instruct users how to properly insert medicine. The app allows for the user to add all necessary contact and medical information, as well tract lost injectors. Lastly focusing on how to dispose of the medicine would be vital.

Redesigned case

I focused on creating the injector to be able to fit into users everyday lives without being in the way, but still easy to locate. 

he case has a couple of main features

  • Green button - means the medicine is not expired and good to use
  • Red button - medicine is expired and needs to be replaced
  • Cap lifts - When using injector, press the green button and the yellow cap will pop open. The top of the yellow cap is a speaker that instructs the user to properly insert the medicine into their thigh. After medicine is injected, the injector syncs with the app on the user's phone to alert emergency contacts that injector has been used.
