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.


Today is world patient safety day, highlighting safe maternal and newborn care. Women who are pregnant sometimes need medicines. Sometimes the reason is a headache, an allergy or a chronic illness. Sometimes health problems start or get worse in pregnancy, like diabetes, morning sickness or high blood pressure. But often there is not enough evidence to give the woman trustworthy information about how her particular medicine might affect the fetus. To bridge the knowledge gap, we are now calling women and their doctors to contribute data by reporting medicine use in pregnancy!  | READ MORE >>
Epithelial cells play an important role in the production of breast milk and transfer of different substances from mother to baby through milk. The ConcePTION project has developed a model to produce epithelial cell cultures from pigs that can help us study medicine safety in breastfeeding. This model is described in a recent paper in Animals, and part of an effort to develop knowledge for women who need to decide between medical treatments and breastfeeding.  | READ MORE >>
Studies of medicines safety and breastfeeding often involve animals. Now IMI’s CONCEPTION project has a plan that could deliver better results while also using fewer animals. | READ MORE >>


Finding information about #MedicineSafety in #pregnancy and #breastfeeding is challenging. But the problem extends beyond a mere lack of data. A recent study reveals that recommendations can also vary between sources!

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.
