"Immunotherapy treatment desensitizes the patient to the cause of their allergies. The treatment has no benefit in fighting allergic reactions to food allergies, but has proved effective in seasonal and pet allergies.
The treatment uses a series of injections to make the patient less susceptible to the symptoms of cat allergy by treating the cause. Your doctor will give you one or two feline allergy shots a week for six months, inserted under the skin. Over time, the injections, which contain extracts of the allergen, will become larger, gradually increasing the tolerance to the source of the allergen. These allergen vaccines make up the build up portion of immunotherapy.
After the desired dosage has been reached, your doctor will begin the maintenance phase. At this point, most of your feline allergy symptoms should have been alleviated. Consequently, your shot frequency will decrease to once a month, for a few years.
The treatment will continue until the patient no longer experiences allergic reactions when around the source. This is a fantastic option for pet owners with mild cases of cat allergy, as the treatment has not proved effective for severe cases."
Sounds like a royal pain in the ass to me
