We are sure that everyone is taking sufficient care of their health on a daily basis, but there may be a situation in which a proxy injection is required in case of an emergency. If possible, please let those around you know that you are carrying an EpiPen®, and try to keep it in an easily visible place in your bag or backpack. If you have any concern during classes (especially in physical education or fieldwork), you may want to contact your professors/instructors as well.
Also, have you checked the expiration date of your EpiPen®? Before it expires, consult your family doctor or your local doctor for a prescription.
If you would like to discuss this matter, please visit the Center for Health Sciences and Counseling on your campus and ask for a consultation. https://chc.kyushu-u.ac.jp/access-en/
