Allergens are substances to which you are allergic. Remember, not all asthma is due to allergies. Allergy shots can be effective against grass, weed and tree pollens, house dust mites, cat and dog dander and insect stings. Allergy shots are less effective against molds and are not a useful method for the treatment of food allergy.
Treatment usually begins with a weak solution given once or twice a week.
The strength of the solution is gradually increased with each dose. Once the strongest dosage is reached, the injections are usually given once a month to control your symptoms. At this point, you have decreased your sensitivity to the allergens and have reached your maintenance level. Allergy shots should always be given at your health care provider's office. If you are considering allergy shots, talk to your health care provider about a referral to board certified allergist.
