It depends what treatment protocol you're following.
The IV protocols for non-life-threatening cases usually involve a number of treatments over a short period (say 6 over 2 weeks), then increased spacing until a satisfactory equilibrium between avoiding symptom recurrence and not spending too often strapped to an IV is achieved.
I believe the nasal spray treatments are more frequent and less potent, but I've no firsthand experience with those, just the knowledge that one of the major limiters on getting a ketamine derivative into people's hands outside of an IV bag is the variability of dosage through e.g. nasal spray. (You can get a prescription for ketamine in a nasal spray from compounding pharmacies right now, but you will likely have decent variability of dosage each time.)
