"rules", what do you mean? I don't understand, hehe. Anyhow...<br>I have searched online for the shelf life of the Iodine and found a similar product with a 2 year shelf life, but it was sealed, as mine is not, so I am not completely sure. I would suggest replacing all medications with fresh ones every 6 mos. to a year.
