Western Allergy's mandate includes our commitment to bringing our customers the best allergy products available, excellent customer service, and on our innovation as new scientific findings come out. In 2001 Western Allergy, taking a cue from European treatment regimens, launched the first clinical trial of sublingual immunotherapy in Canada. This successful clinical trial of sublingual immunotherapy was published in the Annals of Allergy in 2004.  Click here to view the abstract.
