About ITIS

What is ITIS?

The Illinois Teratogen Information Service (ITIS) is free statewide service that is financially supported by the Illinois Department of Public Health. ITIS provides information regarding all types of exposures during pregnancy, and is available to women who are pregnant or planning a pregnancy, fathers, physicians, and other health care providers in the State of Illinois.

ITIS is coordinated by a licensed Genetic Counselor/teratogen information specialist and is directed by a Board Certified Geneticist. Using a variety of resources, the staff collects, analyzes, and distributes information on known and/or potential teratogens. The information is based on current scientific data and the counseling is provided in a non-judgemental manner.

ITIS belongs to a group called The Organization of Teratology Information Specialists (OTIS). OTIS is an organization that serves to provide education, to conduct relevant research, and to support teratology information services throughout North America.

Our Goals:

  • To provide counseling to patients and health care professionals about exposures related to pregnancy and breastfeeding, so they are able to make informed treatment choices.
  • To reduce risks and decrease the number of preventable birth defects by educating the public and health care professionals about specific agents of concern.
  • To empower patients with accurate information about the true risks of an exposure, thereby preventing unnecessary terminations of wanted pregnancies.
