A method of administering a drug to a patient comprises the steps of filling a dispenser (20) with a predetermined total volume of a liquid containing the drug and administering a predetermined volume of the liquid in the dispenser to the patient (10). The liquid in the dispenser is then replaced with a diluent (22). The administration of liquid and replacement with diluent (22) are then repeated from time to time so that diminishing doses of the drug are administered to the patient (10). Preferably, the diluent (22) is drawn into the dispenser (20) prior to the drug containing liquid being administered. The method is preferably patient (10) controlled via control push button (48). The invention extends to apparatus which is used to carry out the method.
