Dear thebear123-ga; Thank you for allowing me an opportunity to answer your interesting question. Here is an example of a product report on the drug Feminax that contains all the substances you mentioned. This is considered a stable drug with an official shelf life of 36 months. PRODUCT SUMMARY - FEMINAX HTML VERSION http://216.109.117.135/search/cache?p=caffeine+tablets+%22shelf+life%22&ei=UTF-8&vm=i&n=20&fl=0&url=pNJdwRin46sJ:www.rocheuk.com/ProductDB/Documents/rch/spc/Feminax_UK_SPC.pdf PDF VERSION http://www.rocheuk.com/ProductDB/Documents/rch/spc/Feminax_UK_SPC.pdf Now, having said that let me direct your attention to the exhaustive report that I am certain will shed a great deal of light on what youve already guessed to be true about ACTUAL SHELF LIFES. REPORTS OF COUNCIL ON SCIENTIFIC AFAIRS HTML VERSION http://216.109.117.135/search/cache?p=analgesic+%22actual+shelf+life%22&ei=UTF-8&vm=i&n=20&fl=0&url=Wv1SHAQJmmEJ:www.ama-assn.org/ama1/upload/mm/interim01/CSA_Reports.pdf PDF VERSION This report explains the differences between expiration dates and use-by dates and goes on to say that in tests, some stable drugs can last up to 107 months. It also says that the military routinely requests (and gets) expiration extensions on its stockpiled drugs and uses them regularly, saving themselves a whopping $263.4 million between 1993 and 1998. On the other hand, while the report never directly addresses the fact that manufacturers would like to keep the expiration dates as low as possible in order to keep you as a regular customer, it does say that as much as $120 BILLION DOLLARS per year is spent on simply replacing expired medications alone! To confirm your suspicions the report says that extension of drug product expiration periods is strictly voluntary for pharmaceutical manufacturers (pg 2 para 7). We arent likely to get any input on the matter from the FDA either as the report so aptly put it, The FDA noted that it lacks the resources to pursue such studies (pg 4 para 2). Below you will find that I have carefully defined my search strategy for you in the event that you need to search for more information.
