What we supply

SCIT allergy shots
Custom name-patient prescription compounds for injection immunotherapy, with build-up and maintenance vials. Administered in clinic with the observation period your protocol requires.
SLIT allergy drops
Daily drops under the tongue, taken at home after a supervised first dose. Western Allergy participated in Canada's first clinical trial of sublingual immunotherapy in 2001 and was first to offer custom name-patient prescription SLIT compounds.
Venom immunotherapy
Hymenoptera venom immunotherapy for patients with systemic reactions to insect stings (honeybee, yellow jacket, wasp and hornet), supplied to allergy practices across Canada.
UF Dog SLIT and SCIT
Dog allergen extract available for both sublingual and subcutaneous protocols, for patients whose symptoms are driven by dog exposure at home or at work.
Skin-testing supplies
DuoTip skin prick test devices, testing allergen extracts, and positive and negative controls: everything a clinic needs to run a consistent skin-test panel.
Onboarding and education
Suggested dosage schedules, the latest immunotherapy research and educational videos with Kimberly Waines, so a practice can start SLIT or SCIT with confidence.

How SCIT and SLIT work, what to expect from a first dose, storage, missed doses and who to call, plus the AllergyPath app to keep track of it all.

For licensed healthcare professionals. Allergen extracts for SCIT, SLIT and venom immunotherapy are prescription products dispensed under the authorization of a licensed prescriber. Allergen immunotherapy, including oral mucosal, oral and sublingual immunotherapy for food allergy, carries a risk of allergic reaction, including anaphylaxis; initiate and supervise therapy per the product labeling and your clinical protocols. Dose tiers reflect available options and do not constitute a dosing recommendation for any individual patient. Confirm current regulatory status and product information before prescribing.
