📍 Most subcutaneous auto-injectors are designed for multiple administration sites, commonly including:
• The abdomen (at least 5cm from the navel)
• The thigh (anterolateral area)
• In some cases, the upper arm (as directed by healthcare providers)
While all approved sites are clinically effective when used as prescribed, patients often report different experiences with each location.
Patients may have varying emotional and psychological responses to different injection sites being certain areas feel more comfortable than others, which can impact their overall treatment experience and adherence.
A study published in Clinical and Experimental Rheumatology of more than 2,000 rheumatoid arthritis patients using an auto-injector showed: https://eu1.hubs.ly/H0nrf8-0
🔹 75% selected the thigh for self-injection
🔹 17% selected the abdomen
🔹 7% selected the upper arm
Factors influencing patient preferences included:
• Visibility and access during the self-injection process
• Individual comfort levels
• Emotional associations with different body areas
At E3D, we believe that a successful treatment journey is built on more than pharmacokinetics—it's built on understanding the complete patient experience.
That's why we design our devices with attention to ergonomics, simplicity, and patient dignity at every step of the treatment journey.
Because how patients interact with medical devices matters for their overall healthcare experience.
*Note: At E3D, we design with patient experiences in mind. This information illustrates our human-centered approach and is not meant to replace medical guidance. Always follow your healthcare provider's specific instructions.*
