Three Types of Immunotherapy Treatments

Immunotherapy (the medical term for allergy shot)

This involves giving gradually increasing doses of the substance to which the person is allergic. This causes the  immune system to become less sensitive to what you are allergic, probably by causing production of a "blocking" antibody, which reduces the symptoms of allergy when your exposed in the future. 

This is the only treatment available that actually treats the root cause of your allergies and that has a chance to cure them instead of just controlling them like medications. Given once a week for 5 months then monthly. Every week a larger and larger amount of pollen is given to a patient.

cluster immunotherapy 

As effective as regular allergy injections but the buildup is in one month instead of five month. Allergy injections are given during a two hour period every week for four weeks then the monthly maintenance dosage is begun. Saves about 5 months of clinic visits for injections.

Sublingual immunotherapy

Sublingual immunotherapy is a fancy name for oral allergy drops. The drops, which contain the allergens that you are allergic to, are taken by placing them under your tongue for a few seconds and then swallowed on a daily basis. This is the injection free way to take your immunotherapy in the comfort of your own home.

Injection free! No shots, great for children

·       Done at home. No trip to the doctor’s office

·       Decreases the chance of future allergies and asthma

·       Can begin two months before the pollen season for patients with spring or fall allergies or used year round for chronic allergy sufferers.

Not covered by insurance in the United States, however the price is similar to most patient medication co-pays around $60 a month.
