I have a lot of co-morbidities. POTS is a big problem with me in any procedure. I also have Addison's. Yes, even a four hour outpatient ketamine infusion is expensive for me, but I require a lot of monitoring. Plus they give me 500 mg over the four hours, which is a pretty big dose.

So in their defense, it's not the cost of the drug that's the big expense. It's the care. I'm happy they'll even do it at all with my other problems.

The inpatient protocol is usually five to seven days in the ICU. That's just going to cost a lot in monitoring and care.
