You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/

That BBQ sauce is labeled "gluten-free," is it possible you got gluten somewhere else, or have an additional sensitivity? https://www.sweetbabyrays.com/sauces/bbq-sauces/original-barbecue-sauce  

Maybe you are allergic to the the Simbicort. I would suggest talking to your physician about an alternative inhaler medication.

Sorry you are having this experience when inadvertently getting Gluten. I have used 3 ounces of water with 2 tablespoons of Apple cider vinegar and 1/2 tsp of honey mixed well and drink. I have also used Nature's Way organic Apple cider vinegar (ACV) Gummies. Bottle says, take two. This is great when I'm out and about and carry them in my handbag. I got them through Amazon. This has made huge difference with all the symptoms mentioned.
