OLYMPIA, WA – The Washington Medical Commission (WMC) restricted the license of Guito Cassagnol Wingfield (License #00048810) following a hearing in June. The WMC found that Dr. Wingfield prescribed ivermectin to five patients for COVID-19 infection without documenting a sufficient rationale for prescribing the medication, without informing the patients that the medication is off-label and not FDA-approved to prevent or treat COVID, without performing an appropriate risk stratification analysis of the patients’ medical conditions, and without discussing alternative treatments with the patients.

The WMC issued a Final Order restricting Dr. Wingfield from prescribing ivermectin for non-FDA-approved indications, and restricting him from prescribing medication or providing care to patients without first establishing a physician-patient relationship by seeing the patient in-person or via real-time video, taking the patient’s history, and examining the patient.

In addition to the restrictions, the Order requires Dr. Wingfield to inform eligible patients that monoclonal antibodies are available and effective to treat a COVID-19 infection, and that COVID-19 vaccinations are effective at preventing severe disease. Dr. Wingfield must also review the Centers for Disease Control website and the UpToDate website for current guidelines; take continuing medical education on the prevention, treatment, and management of COVID-19; complete an ethics course; complete a record-keeping course; and pay a fine of $5000.

Legal documents in this case are available online by visiting the DOH Provider Credential Search.
