Certain mixtures used to treat severe allergy symptoms and given by injection under a physician's guidance, are available to people who are eligible for drug coverage under the Ontario Drug Benefit (ODB) Program.

The ODB program's coverage of allergy products does not include antihistamines or mixtures used to diagnose specific allergies.

The ODB program will pay for covered allergy products only if your physician prescribes the product and completes a special form, on your behalf, for coverage. You must also be eligible for drug coverage under the ODB program.

Allergy Product application forms can be obtained on-line : Special Authorization (Allergen) 

Cost-sharing will not apply to allergy products. The ODB program will continue to cover 100% of the cost of these preparations.
