How long? Which?: Most expiration dates are about half of the actual time that the compounds remain active, but this may not guarantee their activity. Side-effects of the products of these compounds as they deteriorate vary with the compound, but very few if any have serious toxicities. Best to throw them out if they have expired. Better than taking a chance they are inactive or toxic.
