Sanatio Allergy's parent company, Western Allergy Services (WAS), has established itself as the premier supplier of allergy diagnostics, allergy immunotherapy and atopic treatment in Canada since 1972

We pride ourselves on our commitment to bringing our customers the best allergy products available, excellent customer service, and on our innovation as new scientific findings are published.

In 2001 WAS, taking a cue from European treatment regimens, launched the first clinical trial of sublingual immunotherapy (SLIT) in North America. This successful clinical trial of sublingual immunotherapy was published in the in the Annals of Allergy in 2004. As an early adopter, we were the first to offer both custom compounded sublingual immunotherapy and traditional subcutaneous immunotherapy (SCIT) by prescription. We offer our clients the latest research on immunotherapy along with suggested dosage schedules for those new to incorporating SLIT or SCIT into their medical practice.

Our diagnostic scratch test needles, were invented by renown Allergist, Dr Harry Morrow-Brown, and give simple reproducible results at a fraction of the cost of other needles.

Our environmental control  products are excellent adjunct treatment options for those with environmental allergies and eczema.
Sanatio Allergy Bedding offers the highest quality dust mite protection for your bedroom. Made of 100% organic cotton, this specialty bedding product can help reduce asthma, allergy and eczema symptoms by up to 40%.
