an epi pen would only be a consideration if the person was having a true anaphylactic allergic response (difficulty breathing wheezing swelling of the face or any part of your respiratory tract generalized hives etc. ). if this were the case you have no business posting an inquiry you need to call 911 and use that pen. i don't know anything about you (if you are the person) or your level of sensitivity to specifically advise you if you just accidently took an aspirin you may not have any response at all and it will wear off completely in about four hours.
