Embodiments of the present disclosure relate to a drug monitoring tool. The drug monitoring tool comprises a data receiver and an interactive user interface. The data receiver is configured to receive a pharmacokinetic (PK) profile of a patient. The interactive user interface is configured to display, to the patient, a time-varying therapeutic plasma protein level of the patient. The time-varying therapeutic plasma protein level is based on an administered dose of a clotting factor VIII and the PK profile of the patient.
