Warnings & Indications

Hyposensitization therapy is a treatment for patients exhibiting allergic reactions to seasonal pollens, dust mites, animal danders and various other inhalants in situations where the offending allergen cannot be avoided. Prior to initiation of therapy, the clinical sensitivity should be established by careful evaluation of the patient’s history confirmed by diagnostic skin testing. Hyposensitization should not be prescribed for sensitivities to allergens which can easily be avoided. Although allergen immunotherapy has been proven to be highly effective in treating the underlying cause of allergies, patients on allergen immunotherapy may experience side effects. Numerous controlled studies have demonstrated the clinical efficacy of immunotherapy with cat, dust mite, and some pollen extracts. Nevertheless, responses are variable, and in a few studies patients reported no appreciable benefits.
