A drug packaging machine which can provide patients with information of any drug which cannot be packaged in a drug bag if prescribed drugs include such a drug. If prescribed drugs include a drug which cannot be packaged in a drug bag, an empty bag is formed at a position corresponding to the order in which this particular drug is to be taken, and the data for taking this particular drug is printed on the empty bag. A patient can thus take all of his or her necessary drugs simply by following the order in which the drug bags are series-connected.
