I had ketamine treatments a few times a month for a year.
The first 4 were intervenes. The rest were prescribed for a compounding pharmacy as a ketamine nasal spray. 5 doses for $50.
Then the FDA outlawed the non-name brand nasal spray form. Now it’s like $1000 a dose so I stopped.
I loved ketamine. No side affects. Non addictive.
Thanks for the personal anecdote. My smaller town has a clinic run by ARNPs that offers both the IV route and nasal spray (esketamine or Spravato). I believe the IV administration is around $400 and the spray is higher, like you say. Both act as NMDA receptor antagonists.
