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.


Pregnancy should be a time of joy and excitement, although inevitably it is also one of apprehension and concern. Mothers want to be as sure as the can be that they are minimising any risks to their unborn or newly-born child. If they take a medicine - as almost 9 out of 10 do during or after pregnancy – they want to feel reassured they are not posing any undue threat. Now, a new Europe-wide project is asking mothers for their insights in order to help improve knowledge of drug safety. | READ MORE >>
To provide evidence for how a medicine transfers to breastmilk, we need to test milk from mothers who use medicines during the post-partum period. On May 24 2022 at 14-15 CEST, the IMI ConcePTION project is organising a webinar together with BBMRI-ERIC - The ConcePTION European Breast Milk Collection: Supporting research on medicine safety in breastfeeding. ConcePTION is developing a research infrastructure to collect, store and analyse samples of breast milk and blood. Don't miss the opportunity to learn more about the design of our demonstration studies, recruitment of breastfeeding mothers, lessons learned, and first results!  | READ MORE >>
Because pregnant and breastfeeding women are not usually included in clinical trials of new medications, we don’t know enough about the safety of medicines during pregnancy and breastfeeding. But clinical research is not the only way to generate evidence. Using a so-called learning healthcare system approach, care and research align to accelerate evidence by looking at real-life medication use. A recent publication in BMC Pregnancy and Childbirth explores women’s views on adopting such a system, before and during pregnancy as well as while breastfeeding. Using the ConcePTION evidence generation ecosystem as a starting point.  | READ MORE >>

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.
