I don't know what's included in "personal meds" but I'd suggest adding a pretty good dose of antihistamine such as Benadryl or something quite powerful.

Good for treating bee sting for everyone.

This weekend while camping in sagebrush I re-learned how allergic I am and how vital anti-histamines are to my continued functioning in grasslands. (I'm fine in the mountains but not in hayfields and sage brush.)
