Is Low Dose Naltrexone approved by the FDA for PCOS benefits?

The short answer is “No.”

Naltrexone is FDA approved for obesity and the treatment of opioid and alcohol addiction- also known as the on-label indication. However, like many medications, naltrexone is used off-label for conditions such as PCOS and many symptoms and conditions. Like with any medication, once the FDA has approved a medication for one use, a medical doctor can prescribe it in any way they see fit for their patient.
