The Organization of Teratology Information Specialists (OTIS) is the professional society made up of the experts that provide the MotherToBaby website information service and the researchers that perform associated studies. They provide evidence-based information to mothers, health care professionals, and the general public about medications and other exposures during pregnancy and during breastfeeding.

Their website offers fact sheets that answer frequently asked questions about exposures during pregnancy and breastfeeding. The medicines they review are all listed by their generic name. These summary sheets are meant for general information purposes and should not replace the advice of your doctor. Instead, this information can be reviewed and used as a springboard for further discussion in your counseling sessions.
