Treating Chronic Inflammatory Response Syndrome (CIRS) follows a specific, sequential protocol that addresses the condition layer by layer, starting with removing the source of exposure and ending with restoring immune balance. The process typically involves 12 steps completed in order, because each step builds on the one before it. Skipping ahead or treating out of sequence tends to reduce effectiveness. Most people spend months to over a year working through the full protocol under a practitioner trained in biotoxin illness.
Step One: Get Out of the Toxic Environment
Nothing else in the protocol works if you’re still being exposed to the biotoxin making you sick. For most CIRS patients, that means water-damaged buildings with active mold growth. Treatment begins with professional environmental testing, not a standard home inspection. Specialized dust sampling can identify the specific mold species linked to CIRS and generate a score called the HERTSMI-2, which rates how safe a building is for someone with biotoxin illness.
A HERTSMI-2 score under 11 has been considered safe for previously sickened patients. Scores above 15 are too dangerous to occupy. Anything between 11 and 15 is borderline and requires remediation before the space can be cleared. If your home scores high, remediation by a mold-specialized contractor is necessary, and some patients need to relocate temporarily or permanently. This is often the hardest and most expensive step, but it is non-negotiable. Taking binders while continuing to inhale mold fragments is like bailing water from a boat with a hole in it.
Binding and Removing Biotoxins
Once you’re in a clean environment, the next step uses a class of medications called bile acid sequestrants to physically trap biotoxins in your gut and pull them out of your body. The primary medication used is cholestyramine, a powder mixed with water and taken before meals. It works by binding to biotoxins that recirculate through your bile, preventing them from being reabsorbed. Without a binder, these toxins cycle endlessly between your liver and intestines, keeping inflammation active.
The typical starting dose is 4 grams once or twice daily before meals, gradually increasing to between 8 and 24 grams per day split across multiple doses. Cholestyramine can interfere with the absorption of other medications, so it needs to be taken with a time gap from anything else you’re prescribed. Common side effects include constipation, bloating, and nausea. For patients who can’t tolerate cholestyramine, an alternative called Welchol is sometimes used. It’s gentler on the digestive system but considered somewhat less potent as a binder.
Clearing Nasal Infections
A significant number of CIRS patients harbor antibiotic-resistant bacteria deep in the nasal passages, a condition abbreviated as MARCoNS. These bacteria form a protective biofilm coating that makes them difficult to reach with standard antibiotics. Left untreated, they produce compounds that suppress immune function and interfere with hormone regulation, undermining later steps in the protocol.
Treatment uses a compounded nasal spray that combines a calcium-chelating agent (EDTA) with topical antibiotics. The EDTA dissolves the biofilm coating, allowing the antibiotics to reach the bacteria underneath. One common formulation, called BEL spray, contains mupirocin, EDTA, and levofloxacin. An antifungal medication is sometimes added. The original formulation used gentamicin instead of levofloxacin. These sprays are available only through compounding pharmacies and require a prescription. Treatment typically lasts about a month, followed by retesting to confirm the bacteria have been eliminated.
Dietary Changes: The Low-Amylose Diet
Diet plays a direct role in managing CIRS inflammation. The protocol calls for a low-amylose (or no-amylose) diet, which eliminates a specific type of resistant starch found in grains, root vegetables, and certain other high-glycemic foods. Amylose raises blood sugar and can amplify inflammatory markers that are already elevated in CIRS patients, particularly one involved in tissue breakdown and blood vessel permeability.
Foods to eliminate include:
- Grains: wheat, rice, oats, barley, rye, and all products made from them (bread, pasta, cereals)
- Root vegetables and tubers: white potatoes, sweet potatoes, beets, carrots, peanuts (onions and garlic are exceptions)
- Bananas: the only fruit restricted on the diet
- Added sugars: sucrose, corn syrup, maltodextrin
The diet is inherently gluten-free but more restrictive than a typical gluten-free plan because rice is also excluded. Practical swaps include cauliflower rice and almond flour for baking. Most non-starchy vegetables, meats, fish, eggs, nuts, and all fruits besides bananas remain on the table. If blood tests show antibodies to gliadin (a protein in gluten), strict gluten avoidance becomes a separate, earlier step in the protocol, with possible reintroduction only after treatment is complete.
Correcting Hormones and Fluid Balance
CIRS disrupts multiple hormone pathways. One of the earliest casualties is DHEA, a precursor hormone that supports immune function and counteracts the body’s shift into a breakdown state. Restoring DHEA levels is typically handled with supplementation, guided by lab work.
Another common disruption involves the hormone that controls how your kidneys manage water. When this system malfunctions, you may experience excessive thirst, frequent urination, or dehydration despite drinking plenty of fluids. If lab results confirm the imbalance persists after earlier steps are completed, a medication called desmopressin can be used to restore normal fluid regulation. Patients often describe dramatic relief from the constant thirst and brain fog that accompany this particular disruption.
Reducing Inflammatory Markers Step by Step
The middle portion of the protocol targets specific blood markers of inflammation, each addressed in sequence. These aren’t treated all at once because normalizing one often helps bring others into range.
Tissue Breakdown and Oxygen Delivery
Two markers related to tissue integrity and oxygen delivery to cells are typically addressed with high-dose omega-3 fish oil (EPA and DHA), the low-amylose diet, and a carefully designed exercise program. Exercise is introduced gradually because CIRS patients often experience post-exertional crashes. The goal is to improve blood flow to tissues that have been oxygen-starved, which contributes to the fatigue and muscle pain many patients report.
Complement System Activation
CIRS triggers parts of the immune system called the complement cascade, which produces inflammatory proteins that damage tissue when chronically elevated. One of these markers often requires a statin medication to normalize, typically paired with CoQ10 to offset potential side effects. The other complement marker frequently corrects on its own once the first three steps of the protocol (removing exposure, binding toxins, clearing nasal infections) are successfully completed. If it remains elevated, it is addressed in the final step.
Fibrotic Remodeling
A growth factor involved in scarring and tissue remodeling is often elevated in CIRS and linked to restrictive lung patterns and joint stiffness. When it remains high after earlier steps, a blood pressure medication from the angiotensin receptor blocker class can bring it down. This is used specifically for its anti-fibrotic properties rather than for blood pressure control.
The Final Step: Restoring Immune Regulation
The last step in the protocol uses a naturally occurring peptide called VIP (vasoactive intestinal peptide), delivered as a nasal spray. VIP acts as a broad immune regulator, calming overactive inflammatory pathways and restoring balance to the neuroimmune system. Research has shown it can normalize multiple CIRS markers simultaneously and may even help reverse structural changes in the brain associated with chronic biotoxin exposure.
VIP is not started until very specific conditions are met. Patients must have a passing visual contrast sensitivity test, a clean nasal culture showing no MARCoNS, and environmental testing confirming their living space has safe mold levels (an ERMI score of 2 or below). Studies found that starting VIP while any of these three conditions remained abnormal significantly reduced its effectiveness. This is why the protocol is sequential: VIP is the capstone, not the starting point.
Monitoring Progress: The VCS Test
Visual contrast sensitivity testing is used throughout treatment as a low-cost way to track neurological improvement. The test measures your ability to distinguish between shades of gray at different spatial frequencies, a function that biotoxin exposure specifically impairs. When combined with lab markers, VCS testing has demonstrated diagnostic accuracy above 98%. It can be done online or in a practitioner’s office, and improvements in VCS scores often track closely with how patients feel. Many practitioners use it as a quick check at each visit to confirm the protocol is working.
What Recovery Looks Like
CIRS treatment is not fast. Most patients spend 6 to 18 months working through the full protocol, and the pace depends on how quickly each step normalizes the relevant markers before moving to the next. Some steps resolve in weeks, others take months. Setbacks from accidental re-exposure to mold are common and can require repeating earlier steps.
The order matters more than speed. Practitioners trained in this protocol run lab panels at each stage to confirm a marker has normalized before advancing. Patients who try to shortcut the process, skipping environmental remediation or jumping to VIP early, typically plateau or relapse. The sequential design reflects how the underlying biology works: you can’t calm the immune system while it’s still being provoked, and you can’t restore hormones while inflammatory proteins are still elevated.
Finding a practitioner experienced with this protocol is essential. The treatment involves compounded medications, specialized lab panels not included in standard blood work, and environmental testing that most doctors are unfamiliar with. Directories of certified practitioners are maintained through organizations focused on biotoxin illness, and telehealth consultations have made access easier for patients outside major metro areas.
