Oklahoma’s attorney general has told doctors across the state that they can prescribe ivermectin or hydroxychloroquine for the purpose of treating COVID-19 and will not face disciplinary procedures for doing so.

In a statement published on Tuesday, Attorney General John O’Connor said he has found “no legal basis” for a state medical licensure board to discipline a licensed physician for “exercising sound judgment” and “safely prescribing” the drugs.

Neither ivermectin nor hydroxychloroquine has been approved for use in treating COVID-19 by the U.S. Food and Drug Administration (FDA) but O’Connor made clear that doctors would not face penalties if they prescribed either drug for the off-label purpose of treating a patient with COVID-19.
