For many years my key chain pill capsule has been & remains the Bison Designs Capsule, Large. I also wrap the capsule in ~18” of Gorilla Tape. In it I carry 4 ibuprophen tabs; 4 pseudoephedrine tabs.; 2 caffeine tabs; 2 generic Benadryl tabs, & 4 chewable 81mg. Aspirin tabs. This gives me some pain and allergy relief, a legal energy boost ( caffeine + pseudoephedrine,), basic anaphylactic treatment & heart attack minimization.
