Here’s the scenario: your school starts in September and the Epi-pen/Benadryl you brought to the school nurse expires mid-year in December.
What does this mean? Your parents have to come in mid-year to drop off a new set that will last the rest of the year.
Why not make life easier? Make sure the medicine you drop of in September is new so it will last till the end of the school year!
Epi-pens and antihistamines will usually last about a year so purchasing new ones in the summer will generally suffice!
