IMMUNOTHERAPY (ALLERGY SHOTS)
Immunotherapy (Allergen shots)
Another name for allergy shots is allergen immunotherapy. It is a type of treatment that relieves symptoms for people who have chronic allergies. Allergy shots contain small amounts of the thing you are allergic to, called an allergen. The first shot you get has a low amount of the allergen. The dose increases with each shot. Over time, this process helps your body fight the allergen. Your immune system creates antibodies to block its effect. The result is your allergy symptoms become less severe.
What kind of allergies can be treated with allergy shots?
Common allergens include mold and pollen from grasses, ragweed, and trees. You may be allergic to dust mites or an insect that stings, such as bees. Allergy shots also can relieve eye allergies or improve asthma symptoms.
Why should I get allergy shots?
Most people get allergy shots once they have tried other treatments that did not work. These can include avoiding allergens and taking medicine, such as an antihistamine.
Can everyone get allergy shots?
Most people over the age of 5 can get allergy shots. You should not get them if you have severe asthma or heart problems, or take beta blockers. You also should not get them if you are pregnant. Talk to your doctor if you have been taking allergy shots for some time and become pregnant. You may be able to keep taking them.
How many shots do I have to get?
Most people get 1 or 2 shots each week at first. After about 6 months of weekly shots, your doctor will decide when you can start maintenance treatment. These shots usually are given once a month, year-round. You probably will need maintenance shots for 3 to 5 years. If your symptoms are better, you may be able to stop having shots.
