I'm trying to pack light for a trip, and am wondering if there is any reason why I shouldn't just open a few single-serve OTC medicines (like Lactaid and Sudafed), and throw them loose in a pill container, rather than dealing with all the extra packaging. The labels don't mention anything about the drug's efficacy degrading once removed from the packaging, but if that's the case, why even bother with those annoying blister packs in the first place? Has anyone asked their pharmacist whether it's ok to remove single-serve medications from their packaging and store like regular pills?
