My paracetamol doesn't have a expiry date...What is it's shelf expectancy?

there as got to be an expiry date some were on it if not go back to were you bought it from let them find it for you and don't give him any more till this is sorted as this could be an old bottle but i have just looked at my paracetamol tablets they vary one bax say's 2 yrs other is 3 another is 2 month so wouldn't like to comment which is the right i also have just picked a bottle up looked at that the date is 3yrs on that one i only got that 3 weeks ago but for children you can't be too sure with it been liquid but i would take it to any chemist more so the one were you bought it hope this helps you get it sorted
