Agreed. For recent back pain I took a flexeril that was ten years old, never thinking it would have much effect, was just hoping it would help the ibuprophen so I could have a decent Christmas dinner with our entire extended family. What I had was a decent nap on my aunt's couch (and I never nap). I simply could not stay awake. I will never downplay long term efficacy again.

It is patently FALSE that all medications lose efficacy past THEIR "expiration date". The expiration date for prescription meds is almost ALWAYS a year. Why do OTC drugs usually "expire" in 3 years, or so? hmmmm.... The truth: MOST drugs are chemically stable compounds and take MANY years to decrease their effect. The possible exceptions are drugs that must be refrigerated (such as insulin and liquid antibiotics). Personally, I treat ALL antibiotics as "expired" after 18 months or so, but that isn't SCIENCE, that is just me. SCIENCE says the pharmaceutical industry has played us for fools with too much expendable income for too long! Ask the US military what they do about "expiration dates" on medicine... Do as you like, but know that you are ONLY spending money without reason in the case of MOST drugs! We are all free to spend our own cash as we see fit! *shrug*

Flexeril contains the active ingredient Cyclobenzaprine, which is a muscle relaxant and you should contact your doctor for a new prescription, because it does lose efficacy past the expiration date, so it may not work as well as it did, when it was new.

This creates the danger of overdose, by taking more, to get the relief you need.

Almost all medications have a limited shelf life and will start to lose efficacy past that date.

Are there any other questions?
