Patient discussion about citric acid

Q. I have an allergy to citric acid. Is there a cure or preventative for this.......something I can take? Redness of face around features and blurring of vision about half an hour after ingesting. Citric Acid is in a LOT of products.

A. Thanks for trying Justin. For the redness, I use a mix of anti-histamine cream and hydro-cortisone. This doesn't help with the blurred-vision of course; it's just a temporary fix for my appearance. It seems that I just need to find things I can eat that don't have citric-acid added (as a preservative or to add a tangy taste) or that have citric-acid in it naturally (like citrus fruits etc.). I have to avoid foods that have the following on the ingredients list: citric-acid, sodium citrate, E330. Hope this info helps some others!
