About ConcePTION

ConcePTION is a project funded by the Innovative Medicines Initiative, a private public partnership. The project was launched in April 2019.

We believe that we have an important societal obligation to radically and rapidly reduce uncertainty about the effects of medication used during pregnancy and breastfeeding to benefit women in making informed decisions about medications used before, during and after pregnancy.

Reporting medicine use in pregnancy

Did you use any medicines when you were pregnant? Here is how you and your health care provider can report what we call an exposure.

Ten principles for stakeholder engagement in the ConcePTION project

The ConcePTION project is building much-needed knowledge for women and health care professionals. To achieve our goal of building an ecosystem for medicine safety in pregnancy and breastfeeding, we need to engage with women, their partners, their doctors, pharmacists, midwives and nurses, the companies that develop medicines and the authorities that approve them and decide what becomes available to patients. Our goal is to work in an open and inclusive way, with the spirit of mutual respect and trust. Here is how we engage with stakeholders in an ethical way.


A recent paper published by researchers involved in the ConcePTION project explores the complexities of health information collected in electronic databases, commonly used to study the safety and effectiveness of medicines. Understanding the diverse features of these data sources is crucial for researchers to reproduce studies and validate their results. Something that can help us fill the knowledge gap on medicine safety in pregnancy and breastfeeding.  | READ MORE >>
We believe that access to trusted information about the safety of medicines during pregnancy is a fundamental human right. One that is not currently being met. That’s why we’ve developed MUMS (Mothers Using Medicines Safely); a free-to-use, easy-to-understand, publicly accessible bank of reliable information about the use of medicines during pregnancy. The website has been launched in English in June 2024, with translations in Polish and Italian following in the summer of 2024. | READ MORE >>
With 5,000,000 pregnancies each year in Europe alone, there is a pressing need to fill the knowledge gap in medicine safety during pregnancy and breastfeeding. ConcePTION has spent 5 years working to set up an ecosystem for pharmacovigilance in pregnancy and breastfeeding. LifeSaver (Living Impact on Fetal Evolution) is just getting started on their journey towards advancing risk assessment for drugs and chemicals in pregnancy. Together, we work to fill the knowledge gaps. On 14 May 2024, we shared what we do and how we complement each other in a joint webinar. | READ MORE >>

the availability of physiological data in infants for PBPK modelling can be improved by systematic searches, as the physiology of a breastfed is different from a formula fed infant. Relevant for lactation-related drug exposure. https://www.mdpi.com/1999-4923/15/11/2618. IMI Conception.

The ConcePTION consortium

The project unites an unprecedented 88 organizations from 22 countries, including the European Medicines Agency, drug manufacturers, academia, public health organizations, and teratology networks to innovate new solutions to a decades-long public health issue.


The ConcePTION project has received funding from the Innovative Medicines Initiative 2 Joint Undertaking under grant agreement No 821520. This Joint Undertaking receives support from the European Union’s Horizon 2020 research and innovation programme and EFPIA.
