Determine triggering substances by recording products that cause symptoms and those that do not.
Evaluate those products for ingredients. Cross off ingredients found in products from safe list on the unsafe list. This will isolate the harmful substances over time.
Avoid triggering substances.
Mind your diet. Many chemicals occur in food, not just as pesticides, but also as filling agents, preservatives, natural and artificial flavorings and colorants. Work with a dietician or nutritionist to eliminate foods that produce symptoms.
Mind your medicines. Many ingredients that are triggering may also be found in over-the-counter drugs and prescription medication. Make sure your doctor records ALL medication intolerances in your chart as allergies.
Wear a respirator that is designed to filter GASSES/FUMES, such as a 3M 6200, 6500, 7000 or FF-400 Series half or full face piece with 60923, 60926 or 60928 cartridges. These will also protect you (but not others) from COVID-19 as they are also designed to filter particles.
Obtain 1 or more air purifiers for home use. HEPPA and activated charcoal and carbon filtration are necessary components of effective air purification.
With your doctor and care coordinator, write a care plan for the hospital/ER and obtain needed accommodation letters for clinic care, in-home care, public spaces, transportation, housing (if you rent), education and work.
Determine accommodations for social situations and meeting people in person or sharing home space. Educate the people you meet in person with about how to decontaminate themselves, mitigate an exposure and remediate a contaminated space.
With your care team, formulate an evacuation plan if your home space becomes contaminated. This means finding places in the community you can safely stay while your home space is being remediated.
