VIP Side Effects Comparison — Dose-Dependent Profiles

The relationship between VIP dose and side effect incidence is linear and well-characterized. Understanding this relationship allows researchers to structure protocols that balance efficacy with tolerability. 50–100 mcg (low titration start) 5–8% 4–6% 2–4% 3–5

  • The relationship between VIP dose and side effect incidence is linear and well-characterized. Understanding this relationship allows researchers to structure protocols that balance efficacy with tolerability.
  • 50–100 mcg (low titration start)
  • 5–8%
  • 4–6%
  • 2–4%
  • 3–5%
  • Minimal side effects; effective for dose introduction and tolerance assessment. Ideal starting range for VIP-naive subjects.
  • 100–200 mcg (moderate therapeutic)
  • 12–18%
  • 10–15%
  • 6–10%
  • Moderate incidence; most effects are transient and resolve within 60 minutes. Standard maintenance range for most research applications.
  • 200–400 mcg (high therapeutic)
  • 22–28%
  • 18–25%
  • 10–14%
  • Higher incidence but still predominantly mild. Appropriate for subjects who have completed 2–3 week titration and tolerate lower doses well.
  • >400 mcg (exploratory/single-dose studies)
  • 30–40%
  • 25–35%
  • 15–22%
  • Side effects are expected and frequent. Reserved for single-dose experimental protocols; not suitable for sustained administration without medical oversight.
