Medication Safety

We encourage CareOregon providers to check the U.S. Food and Drug Administration MedWatch web site and sign up for the FDA Drug Safety Newsletter to receive safety alerts via e-mail. We will inform you if CareOregon takes any formulary actions in response to a safety alert.


Adverse Events and Errors

Be sure to report serious adverse events and medication errors. A medication error is "any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of the health care professional, patient or consumer. Such events may be related to professional practice; health care products, procedures and systems, including prescribing; order communication; product labeling, packaging and nomenclature; compounding; dispensing; distribution; administration; education; monitoring; and use."

  • Report serious adverse medication reactions, product quality problems and usage errors online at, by phone or by submitting a MedWatch 3500 form by mail or fax.
  • Report medication errors to CareOregon at 503-416-4100 or toll-free at 1-800-224-4840 from 8 a.m. to 5 p.m. Monday through Friday.
