Hi Shereta,
How incredibly scary for you!! Big hugs your way!! My son has anaphalactic degree food allergies to Walnuts, Peanuts, Tree-nuts, fish and shellfish. I praise God that we have not had to use his Epi-pen yet. I did find out the hard way about his food allergies when he is 1 1/2 years old. I was baking cookies and my little man came into the kitchen. I gave him the tiniest piece of walnut, he just tasted the walnut- just touched it to his toungue and he immediately broke out into hives around his mouth. I gave him Benadryl called the nurses line (who got an EpiPen prescribed immediately) and then got him within a couple of days to have his allergies tested. He was ranked extremely high/off the charts on a few of the allergens.
Thankfully he is old enough to know how to use the practice EpiPen and understands EXACTLY what anaphalaxys means. He asked me when he was six (last year) and I felt he was ready to hear the scary truth. I did NOT want him feeling brazen enough to "try it out" with nuts or any other allergens.
So far he has not been stung by a bee or other flying creature, but he knows not to go near them if he can avoid it. Bless your son's heart to have literally stepped into those nasty buggers!!
Long story short, the EpiPen JR. (in my case) has a practice EpiPen (not sure about the adult one). The instructions are right on the EpiPen and it is incredibly easy to use (Thank God!!!!). You remove the grey cap, a sharp blade will pop out of the black end on the other side, you jam it hard into the side of the thigh and hold it there for 10 seconds. Then either call 911 or get him to the ER immediately!! Make sure to bring the EpiPen with you so they can check how much of the medication actually got into his system.
Now having said that, I am not a medical professional, just a Mom who like you has had to become educated about a very scary and potentially tragic situation.
Big healing hugs to you and your family!
Pam
