- Intranasal spray
- 24–40 IU
- 40–60 minutes
- 2–3 hours
- Moderate (mixed CNS + peripheral)
- Most studied route; evidence base strongest for social anxiety contexts; timing matters more than dose
- Subcutaneous injection
- 5–10 IU
- 15–30 minutes
- 1–2 hours
- Low CNS, high peripheral
- Faster peripheral effects (HPA axis modulation) but limited direct CNS penetration; less evidence for anxiolytic efficacy
- Oral / sublingual
- Variable (poor absorption)
- Unreliable
- Minimal
- Negligible
- Not supported by clinical evidence. Oxytocin is a peptide degraded by gastric enzymes; bioavailability effectively zero
- Intravenous infusion
- 1–4 IU/hour
- 10–20 minutes
- Duration of infusion
- Minimal CNS, high peripheral
- Used in research settings for controlled dosing; not practical for anxiety treatment; peripheral effects only
