My doctor prescribes ketamine lozenges. They are quite cheap, safe, and possibly as effective as IV (more research needed here). He said his insurance didn't change at all. What the world needs is psychiatrists who are willing to take the _risk_ of prescribing a safe drug with a long history in medicine.

Yes, the long-term effects of taking ketamine frequently are not well understood. In my opinion a patient with TRD should be allowed to take this risk provided that they have tried several other drugs.
