Illinois has suspended the license of a former school nurse charged with taking students' medications and switching them with look-alike pills.

39-year-old Amber Elder's suspension was indefinite and for a minimum of 3 years.

Elder has been a registered nurse since 1996. She had no prior disciplinary record from her work at three schools in the central city of Sullivan.

She faces three felony counts of manufacture and distribution of a look-alike substance and three misdemeanor counts of endangering the life and health of a child. She has pleaded not guilty and is free on bond.

She's accused of taking students' Ritalin and Adderall, stimulants prescribed for attention deficit hyperactivity disorder.

Parents complained when they noticed tampering with their children's medications.
