Yes, I have had to administer the EpiPen to my son last year. He was 7 and ingested a tree nut. He was rushed by ambulance to the pediatric ER where he spent the next several hours for treatment and observation. I've also been to the ER on two occasions as a child after bee stings.
I always carry the EpiPen for my son and myself in case of anaphylaxis. I also carry benadryl for mild allergic reactions, like the one he gets when he's around dogs and gets itchy, breaks out in hives, and starts sneezing like crazy. Of course this is uncomfortable, but in this case, the symptoms do not progress into anything more serious, and benadryl is sufficient.
Allergic reactions exist on a continuum from mild to moderate and then severe/anaphylactic.
Anaphylaxis is a severe, life-threatening condition. Whenever anaphylaxis is suspected, the treatment is epinephrine (EpiPen, or similar) immediately and then you call 911. With anaphylaxis, time is of the essence, because the symptoms can progress rapidly. Therefore, swift administration of epinephrine is required. After epinephrine, the patient must be seen in the ER for continued observation and monitoring even if the symptoms seem to subside. This is critical because a secondary, or bi-phasic reaction can occur; these are severe, very serious, and much more difficult to control.
Benadryl is an antihistamine, and while antihistamines help with mild allergic reactions (e.g. mild itching or hives), they CANNOT stop or reverse anaphylaxis. Benadryl doesn't "buy time" with anaphylaxis and will not reverse the potentially fatal systemic respiratory or circulatory reactions that occur in anaphylaxis.
The first line of defense should be continual education and strict avoidance of allergens. Please go to The Food Allergy Research and Education website at www.foodallergy.org. This is absolutely the BEST resource for anyone with allergies or who has kids with allergies or works with allergic kids (teachers, coaches, etc.). It has an entire section on anaphylaxis and a helpful guide for staying safe while eating in restaurants and much, much more.
Are you working with an allergist? If your children's and your allergies are that severe, you really should be. Every allergist I know gives patients an allergy action plan that's like a flow chart that tells you exactly what to do, what to administer when certain symptoms are present. Our school district requires them for my son, and any other child who has an Epi-pen and benadryl at school. My son had to have one for summer camp as well. We have one at home for when grandmas are visiting or when we have a babysitter.
I cannot imagine anyone who has ever had an anaphylactic reaction not having an allergy action plan. Please, please talk to your allergist about this and get one for each of your children, and make copies to have at home, school, and to leave with any person who cares for them in your absence.
Also, please check out the website to review the signs and symptoms of anaphylaxis and assure yourself you'll know what to do in the event of another emergency.
All the best to you and your children!
