Allergy immunotherapy is the only FDA approved established way to decrease a patient's sensitivity to a variety of allergens.

Immunotherapy can be given by subcutaneous injection or sublingual drops.

Immunotherapy can be prescribed to treat a variety of pollens including trees, grasses, ragweed and other weeds.  Dust mite, mold, cat and dog allergy can also be treated this way. Immunotherapy extract contains no chemicals, it is only the natural substance given in a liquid solution to accomplish a desensitized state.
