A medication recordkeeping device comprised of a label or sheet with a plurality of characters identifying at least one subject upon which a friably removable mask covering obscures each of the characters. The label or sheet is adapted to be fixedly applied to a medication containing vessel wherein each time an individual unit of medication is consumed, the friable removable mask is removed from a character in order that the underlying subject will be exposed so that a visual record will be kept of the medication consumed. The characters may be dates, numerals or dosage amounts corresponding to a patient's needs or the particular requirements of the medication. The label or sheet preferably also includes an area for recording important information such as a patient's name or medical history. A bar code may be provided for recording relevant information. Further, the label or sheet can be inserted into a housing apparatus which attaches a medicine container thereto.
