A medication cart a includes a housing mounted on four posts at corners of the housing with a generally horizontal counter top at the top of the housing and a plurality of drawers in the housing underneath the counter top having locations therein for containing medications and for containing data charts relating to medications to be dispensed to a number of patients. The housing is mounted on a base with a plurality of ground wheels for movement by an operator over the ground to different locations to service a series of patients with the medications. A lifting mechanism for lifting the housing relative to the base is defined by four threaded rods each extending generally upwardly between the base and the housing with a lower end of each rod attached to the base and an upper end extending into a respective post. A nut on each rod is connected to the housing such that rotation of the rods causes axial movement of the nut along the rod and lifting of the housing relative to the base. The rods are driven by a hand crank at the top of one rod and a chain and sprocket drive arrangement connecting between the rods at the base.
