I am VERY allergic to polyethylene glycol and sodium laurel sulfate. I have had severe breathing problems, and headaches as well as tightness in the chest, swelling of the mouth, throat gums, lips and anaphalaxis. So far I have found that Claritan, Zyrtec, AllerD, Benadryl and Xyzal all have P.E.G. in them. I have had a very stubborn virus for 3 weeks now with a very runny post nasal drip, that is aggravating my throat, lungs and bronchi. Have been unable to find a decongestant/expectorant without P.E.G. Any ideas? Thanks.
