More and more doctors are using ketamine every month. My daughter got it from a doctor who is NOT on any list. She went in through the ER a few times and was admitted. When the resident called me about it (she is away at college), I told him the only thing I thought might help were ketamine infusions. They were aware of ketamine and took the time to investigate and ultimately ended up giving it to her twice. Sometimes you just have to keep working it. And remember, she was an ER admit. Insurance had to take care of whatever the doctor ordered. Don't know all insurance coverages but this was BC.
