Project-related research and publications

Research projects

The project will produce basic information on the quantity and quality of drugs used during pregnancy as well as their effect on the progress of pregnancy and the health of the fetus and the newborn. The information is meant for the internal use of the participating organisations. In addition, the project includes ongoing separate studies on long-term illnesses during pregnancy and related effects of drug treatments. Some of the separate studies are national or international joint studies.
