AI explanation

Vasoactive Intestinal Peptide Nasal Spray

Imagine your body has a natural calming messenger called VIP that normally keeps inflammation in check and helps your nervous system stay balanced. Some people—especially those with chronic inflammatory conditions, dysautonomia, or lingering effects from infections—don't make enough of this messenger. That's where VIP nasal spray comes in. It's a compounded medication that delivers this peptide directly through your nose, and it's become a cornerstone treatment for people whose immune systems seem stuck in overdrive.

Here's how it actually works: when you spray it nasally, the VIP gets absorbed straight into your bloodstream and also travels directly to your brain through your olfactory nerves—essentially taking a shortcut through your nose. Once there, it activates special receptors that tell your body to calm down. It relaxes your blood vessels, opens your airways, damps down inflammatory signals, and helps regulate your gut. In your brain, it acts like a reset button for your circadian rhythms and protects nerve cells. Essentially, VIP replacement restores the anti-inflammatory and balancing signals your body was missing, allowing your overactive immune response to settle and your nervous system to recalibrate. The nasal route is clever because it avoids your liver's digestive process, keeping the peptide effective long enough to actually work.

Dosage Information

Typical Dose

50 mcg twice daily intranasally

Frequency

Twice daily — morning and evening

Morning or evening

Administration

Intranasal spray (compounded)

Half-Life

~15 minutes

estimated

Notes

Must follow Shoemaker protocol sequence before initiating VIP — not appropriate as a first-line treatment without prior steps. Requires prescription and compounding pharmacy. Not appropriate if active MARCoNS or ongoing mold exposure.

Why this matters

Nasal delivery extends VIP activity; twice-daily dosing in clinical protocols.

Frequently Asked Questions about Vasoactive Intestinal Peptide Nasal

What is Vasoactive Intestinal Peptide Nasal?

Vasoactive Intestinal Peptide intranasal is the compounded nasal spray formulation of VIP used in the Shoemaker CIRS (Chronic Inflammatory Response Syndrome) protocol and studied for dysautonomia mast cell activation syndrome and long COVID. The intranasal route provides direct delivery to brain regions expressing VIP receptors through olfactory pathways while also achieving systemic absorption across the nasal mucosa. This formulation requires compounding pharmacy preparation and is the standard form used in CIRS treatment protocols.

How does Vasoactive Intestinal Peptide Nasal work?

VIP intranasal acts through VPAC1 and VPAC2 receptors in the nasal mucosa systemic circulation and potentially directly in the CNS via olfactory pathways. Systemically it produces vasodilation bronchodilation anti-inflammatory immune modulation and gut motility regulation. In the brain VIP acts as a circadian rhythm synchronizer in the suprachiasmatic nucleus and has neuroprotective effects. In CIRS the deficiency of VIP is associated with chronic systemic inflammation dysautonomia and multisystem symptoms — VIP replacement reduces inflammatory mediator levels improves autonomic function and resolves many downstream sequelae of biotoxin illness. The intranasal route avoids the first-pass metabolism and rapid systemic clearance that limits injectable VIP formulations.

What is the recommended dosage for Vasoactive Intestinal Peptide Nasal?

The typical dose is 50 mcg twice daily intranasally. Twice daily — morning and evening. Administration: Intranasal spray (compounded). Must follow Shoemaker protocol sequence before initiating VIP — not appropriate as a first-line treatment without prior steps. Requires prescription and compounding pharmacy. Not appropriate if active MARCoNS or ongoing mold exposure.

What are the side effects of Vasoactive Intestinal Peptide Nasal?

Flushing and warmth (common, transient). Headache (common initially, resolves). Nasal irritation (common). Hypotension at higher doses (uncommon). Worsening symptoms if used out of protocol sequence
