Thoughts??

Trying to see if you guys would have done things differently...

Had an afterschool staff member approach me today stating they felt like they were having an allergic reaction to the dipping sauce they ate with their chicken wrap. They stated they had NKA and had eaten this meal before. Face was flushed but no swelling. C/o scratchy throat. They were located in another building so we walked back to my office after they stated they felt OK to do so. O2 sats were normal. They denied SOB, difficulty breathing, or feeling like their throat/tongue was swelling. HR was normal. Lungs were clear. They did not appear to be in any distress. I administered 25 mg of Benadryl and had them stay in my office for observation. Approximately 10 mins after the meds, they stated they were feeling better. O2 sats were sill perfect, HR was still normal (I kept my pulse ox on them the whole time) and their face was no longer flushed. At the 15 minute mark, they verbalized continued improvement. I encouraged them to call their roommate to come pick them up as I did not want them driving home since they had taken Benadryl. Friend arrived right at the 30 minute mark after meds and they stated they were feeling much better and were ready to leave. I did instruct them to go to the ER should the symptoms return or worsen to which they verbalized understanding.

We do not have stock epi on any of my campuses but I do have one set of pens that was abandoned that I held on to. It was last checked at the beginning of the year and was still good at that time. I was hesitant to use them as the first response, but was ready to do so at the first sign of decline. But I'm curious...would you have used one or opted to go the route I took?
