That's what I can't seem to find out. I've searched and all the mention I can find is of people with confirmed PA - nothing said about soy allergy, but I presume that if they were known to be soy allergic their soy allergy would have been blamed for the reactions rather than their PA.
Most of the references I can find WRT Atrovent and peanut allergy date from 1998-2002. It may be that when inhalers were redesigned a few years ago to eliminate CFCs, that they removed the soy component. I found the pharmacist insert from Atrovent Inhalation Aerosol dated 2002 that lists soya lecithin as an ingredient. All the "new" info I can find is for Atrovent HFA (post-CFC removal??) and there is no mention of soy in the ingredients (dated 2008) nor is peanut allergy listed in the contraindications section as it was on the 2002 insert.

Yes, twinturbo, that's what I've always heard. For some reason the soy component in the Atrovent inhalers has caused reactions in some PA people.
QuoteIpratropium and ipratropium/albuterol metered dose inhalers (Atrovent and Combivent); contain the phospholipid soya lecithin, a legume related to peanuts, as a suspending agent. Anaphylactic reactions have occurred in patients with allergies to peanuts or soybeans who have received Atrovent. Soya lecithin is only used in the Atrovent and Combivent inhalers; the nasal spray and nebulized solution do not contain phosphatidylcholine, phosphatidylethanolamine, and phosphotidylinositol.(the phospholipids extracted from soybean oil that formulate Soya Lechtin)
