Is allergen immunotherapy really necessary?

If your child's doctor has recommended allergy shots for her constantly running nose you may be wondering, Is this really necessary? Also called allergen immunotherapy, this treatment involves a series of small injections of an allergen; the allergist gradually increases the dosage over time, helping the patient to develop a tolerance to the allergen. 

Runny noses don't really bother most children—they just wipe their noses on their sleeves! However, many kids with nasal-allergy symptoms go on to develop asthma because of the continued stimulation of their immune systems over the years.

Allergy shots are given to children as young as age 5 who have significant allergies, in part because the shots have been shown to help prevent allergic asthma from developing. In a study of more than 200 kids with pollen allergies, the odds of getting asthma were cut by more than half for those who received allergy shots for three years—weekly at first, then every six weeks or so. That may seem like a long time and a lot of shots, but asthma can be a serious and lifelong problem once it has been established. If you're concerned, get a second opinion.
