Read this article and then decide. http://articles.mercola.com/sites/articles/archive/2000/04/02/drug-expiration-part-one.aspx If an organization as large as the US military deems it unnecessary to toss out most medicines, save for a few specific classes (antibiotics, insulin, nitroglycerine), I will take my cue from them. Expiration dates are a brilliant, and I do mean brilliant, marketing scheme. Medicines don't go from effective to inert the day the expiration date is reached. They don't go from medicine to lethal poison at the strike of midnight. I use stuff long past the expiration date, and do so with no qualms whatsoever. Gauze is gauze, and even if the package is damaged, if it's that or having someone bleed out, I will use it. Even if by some miracle the patient gets an infection from that gauze, an infection can be treated. Death from exsanguination can't.
