I sent a colleague to see a hotel guest
perhaps thirty years ago. He didn’t carry a bag as well stocked as mine but
took some drug samples from the office. He gave one out. Later the guest
noticed that its expiration date was past. His anger, when he phoned me,
remains a vivid memory.
Commercial prescription drugs are probably OK
for years after they expire, but we don’t give them out. My bottle of nasal
spray has an expiration date, and it’s pure salt water. When my aspirin
expired, I kept it around.
My lawyer has tapped me on the shoulder and
warned me to add that this is my personal opinion, that I have no special
pharmaceutical expertise, and that you must never take an expired drug.
