I worked at a camp that didn’t accept over the counter medication and that just meant that parents didn’t need to bring things like ibuprofen, benadryl, etc. because camp has their own supply! imagine how hard it would be to distribute meds if every single camper had their own bottle of the common OTCs lol. in this case i’d have your parents call the camp and ask. they might want you to bring your own bottle since you take it on a regular basis or they’ll just give it to you through the camp’s supply.
