OMAHA, Neb. (AP) — Nebraska’s attorney general said Friday that he won’t seek disciplinary action against doctors who prescribe controversial, off-label drugs to treat and prevent coronavirus infections, as long as they get informed consent from patients and don’t engage in misconduct.

The office of Attorney General Doug Peterson released a legal opinion saying it didn’t see data to justify legal action against health care professionals who prescribe ivermectin, a decades-old parasite treatment, or hydroxychloroquine, a malaria drug that former President Donald Trump took to try to prevent a COVID-19 infection.

“Based on the evidence that currently exists, the mere fact of prescribing ivermectin or hydroxychloroquine for COVID-19 will not result in our office filing disciplinary actions,” the Republican attorney general said in the opinion.

Many health experts and leading medical groups have been trying to stop the use of both drugs, arguing that they can cause harmful side effects and there’s little evidence that they help. It’s also unclear whether many doctors are actually prescribing them in Nebraska or elsewhere, although a few isolated cases have emerged nationally.
