Medication Validity: Fact or Fiction?

The U.S. Armed Forces spent millions of dollars annually disposing of expired medications, which raised an important question: would the expiration date truly affect the drug's efficacy?

Harvard Medical School, among other prominent North American institutions, studied the efficacy of expired medications between 2012 and 2017 and concluded that the vast majority of medications (90%) would have similar effectiveness for up to potentially 10 years past their expiration date. As the studies ran for 5 years, there was no change in efficacy during this period.

It is true that a drug's effectiveness may decrease over time, but most of its original potency will still be present even a decade later. High-potency pain relievers can last up to 40 years. However, some antibiotics, insulin, and solution-based products (syrups) may lose their efficacy over time.

Our question is, does the pharmaceutical industry not possess this knowledge?

How many repurchase medicine because it has expired, when, if properly stored away from heat and humidity, its validity would be several times longer than what is on the label.

We remind you that: any use of medication (within or beyond its shelf life) must be prescribed by a physician. Self-medication can be very harmful or ineffective for your needs.
