It can be complicated to decide the dosage of a drug. Healthcare professionals will be forced to consult the details of the SMPC and calculate the dose mentally with a risk of error. By leveraging new technologies, we offer a web application and a mobile application for healthcare professionals that will help them determine the appropriate dose based on the SMPC. These applications comply with all legal and medical requirements. We have developed applications for Merck (fertility calculator), Novo Nordisk (calculator for hemophilia treatment) and many others. Healthcare professionals have all claimed that these applications have simplified the preparation of a prescription.
