(Medical Xpress) -- The Food and Drug Administration in the United States has approved a request by Proteus Digital Health to allow for the inclusion of tiny digestible microchips into medicines to assist health care workers in monitoring intake of medicines by patients. Previously, the FDA had allowed such microchips only in placebo products. Proteus, the maker of the chips, plans to market them to drug manufactures who can then imbed them in individual pills that allow for electronic reporting to doctors letting them know if and when patients take their medicines.
