Nevada’s governor signed an executive order Tuesday limiting the use of anti-malaria drugs chloroquine and hydroxychloroquine for coronavirus patients.

Democratic Gov. Steve Sisolak’s emergency regulation limits the prescription of the drugs in outpatient settings — not in hospitals or emergency rooms — to a 30-day supply, to ensure they’re available for “legitimate medical purposes.”

The action also aims to prevent stockpiling the meds, which are also used to treat arthritis and lupus.

“While these drugs serve necessary medical purposes, this regulation protects the Nevadans who need them and prevents unnecessary hoarding,” Sisolak tweeted.

The move came after President Trump touted the drugs as holding promise for treating COVID-19, creating a flurry of demand.

Trump said last week that chloroquine “could be a game-changer” and that the FDA had approved it as treatment for coronavirus sufferers, which it has not. Trump also said hydroxychloroquine could be used in prevention.

But the country’s leading infectious-disease doctor, Anthony Fauci, said there is no substantive proof, at least yet, that either drug works in the battle against the deadly pandemic, only anecdotal information so far.

Sisolak’s order came a day after a Phoenix-area man died and his wife was in critical condition after taking an additive used to clean fish tanks called chloroquine phosphate, similar to the drug used to treat malaria.

As of Tuesday, New York hospitals have federal permission to give desperately ill patients a cocktail of hydroxychloroquine and azithromycin on a “compassionate care” basis.
