An automatic intravenous flow regulator for regulating the infusion rate of a parenteral solution flowing from an intravenous fluid container to a patient. When the level of parenteral solution in the container is above a threshold level, the infusion takes place at a first flow rate. When the level of fluid in the container drops below the threshold level, fluid flow continues but at a second flow rate less than the first flow rate. The flow rate is controlled principally from outside the IV container; while in a second embodiment, the flow rate is controlled from within the IV container. Other embodiments are disclosed including one in which the initial flow rate may be adjusted; one in which the fluid is filtered prior to delivery to the patient; one in which the initial flow rate is maintained at a constant value with time, secondary flow rate remains fixed, and complete filtration of the intravenous solution being infused is provided.
