Drugs and Pregnancy, Finnish Institute for Health and Welfare (THL)

The 'Drugs and pregnancy ' project' is a co-project of the Finnish Medicines Agency (Fimea),the National Institute for Health and Welfare (THL),and the Social Insurance Institution of Finland (Kela). The project started in 2008 and was preceded by a previous pilot study (2003-2007). Data in 'Drugs and pregnancy ' are based on the national health registers of Finland,including information on all pregnancies in Finland 1996-2020 ending in birth (n=1 407 846) or abortion (n=252 833). Information on perinatal health and malformations,maternal reimbursed drug purchases and chronic diseases prior to and during pregnancy is included in the data. The data are annually cumulating. The aim of the project is to evaluate the pattern of drug use during pregnancy and to estimate the effect of drug use on pregnancy outcomes,including perinatal health and major congenital anomalies.
