I would skip all the meds. Giving meds to someone else can be problematic, including Benadryl which is usually contraindicated in asthma patients. Cough drops, that contain iodine, can be problematic for those who are allergic (and they might not know it yet). Aspirin is usually contraindicated for those under 19 years old because of the potential for Reyes Syndrome. I would certainly rule out the Epinephrine that was mentioned. If someone needs it, they will have it, and young scouts would not know when it was warranted in the case of those with an undiagnosed allergy. IIRC correctly from your oral airway thread, we are talking about "non-certified" 13 year old scouts. They should not be dispensing medications. Even ones that are common and generally considered safe.
