If you have allergies, regular shots (immunotherapy) are designed to make you less sensitive to allergens over time.

The American Academy of Allergy, Asthma and Immunology says you may be a candidate for allergy shots if:

• Your symptoms are moderate-to-severe and your allergy season lasts a few months or more.
• You want to avoid long-term use of allergy medications.
• You can commit the time needed for getting regular allergy shots.
• You can afford the cost of allergy shots and related medical visits.
