“This study provides additional evidence that many prescription pharmaceuticals retain their full potency beyond their manufacturer-ascribed expiration dates,” the authors write in their research report.

“Given the potential cost-savings, we suggest that current practices of drug expiration dating be reconsidered.” Faced with huge expenses for restocking expiring pharmaceuticals, Do D came to the same conclusion in 1985.

The medications tested by Cantrell and colleagues contained several common ingredients.

Of these, only aspirin and amphetamine had deteriorated below generally recognized minimum acceptable potency.

In the first batch of 56 items tested, 84% were given conservative extensions of as long as three years.According to the authors of the research letter, “each dollar spent on SLEP to demonstrate longer than labeled drug stability results in to saved on reacquisition costs.” To convert those dollars to savings per drug, Guill noted that, “in 2006, we tested ciprofloxacin and extended it for two years, saving the U. government in excess of

In the first batch of 56 items tested, 84% were given conservative extensions of as long as three years.

According to the authors of the research letter, “each dollar spent on SLEP to demonstrate longer than labeled drug stability results in $13 to $94 saved on reacquisition costs.” To convert those dollars to savings per drug, Guill noted that, “in 2006, we tested ciprofloxacin and extended it for two years, saving the U. government in excess of $1.5 million on that one product alone.” She added that, “in Israel, the only other country with a shelf life extension program, testing of ciprofloxacin is predicted to result in savings of more than 60 million shekels [$15.3 million] over a period of 10 years.” These extensions — and savings — are possible because the FDA does not require manufacturers to actually determine how long a drug will remain stable.

The expiration date, typically 12 to 60 months from date of production, reflects a minimum window, the period through which the manufacturer guarantees the medication’s potency.

Suspensions are especially susceptible to freezing. Limiting factors with ophthalmic drugs include evaporation of the solvent and the continued ability of the preservative to inhibit microbial growth.9Epinephrine solutions in auto-injectors may lose potency after the expiration date.

In a study of 34 pens that had expired 1-90 months previously, the decrease in epinephrine content was proportional to the number of months past the expiration date.10 One study found that pens 3-36 months past their expiration dates contained 84.2-101.5% of the labeled dose,11 but a study of pens stored in EMS vehicles that had expired 1-11 years previously found that only 12.6-31.3% of the labeled dose remained.12 No data are available on other epinephrine auto-injectors such as .13CONCLUSION — When no suitable alternative is available, outdated drugs may be effective.

Medications are retested annually or biannually to confirm or further extend the expiration date.
