Some embodiments of the present invention include a digital scale to measure a weight of a user who stands on the digital scale; and to calculate and convey to the user a dosage of a medicament which is appropriate for the user based on the measured user weight. The digital scale may determine the medicament dosage by performing a local query to a locally-stored medicament database which may be stored locally within the digital scale, and/or by performing a remote query to a remotely-stored medicament database which may be stored externally to the digital scale.
