Allergy shots are not a magic bullet that will cure your allergies, however they can reduce the symptoms and make life easier. If you have severe allergies that last 3 months of the year or more, or you can't take allergy medications because of the side effects or adverse interactions with other medications you may be taking, allergy shots may be a good option.
Allergy shots can be given to children older than 2 years or older and adults without heart problems or severe asthma. To determine if allergy shots are right for you your doctor will review your medical history and do a medical exam. To identify your specific allergen(s), a series of allergy tests will be performed to decide what, if any allergy shots could be beneficial. It's important to perform the testing in small amounts to ensure there are no adverse reactions to the allergens.
If you don't like needles and the idea of taking a series of shots, you'll be happy to know that the needles used for for immunotherapy are smaller than needles used for most immunizations and medications.
To work properly and safely, allergy shots must be given in a series over time, so patience will be needed for the minimum of 6 months the series of shots will need to be administered. After the initial series, maintenance therapy will be usually be continued for 3-5 years.
If you suffer from allergies for more than 3 months out of the year, talk with your doctor to see if allergy medications or shots are a good option for you.
