Will taking expired allergy medicine hurt you?

Big question. There are a lot of allergy medications & your time span is enormous. Could you take a medication that expired last month? Yes. Last year? Yes, but it might not work as well. Five years ago? Sure but why bother? Medications don't become dangerous as they age just gradually less effective. One exception is Epinephrine it rapidly loses effectiveness after expiration & its needed to save lives.
