Cluster immunotherapy is a method for rapidly desensitizing patients to inhalant allergens. Our cluster protocol involves giving a person multiple allergy injections over several hours over several days, achieving a near-maintenance dose in a very short amount of time. In this way you can do a year's worth of allergy shots in 3-6 weeks! The procedure involves 2-3 rounds of allergy injections, with incremental increases in dose, which are given in a span of 1.5 to 3 hours. After CIT, a person comes into the allergist’s office once a week for the next several weeks. Then we will start spacing out the frequency of your injections according to our immunotherapy (IT) protocol.
More rapid clinical improvement with fewer visits for injections. Allows the patient to achieve maintenance dose more rapidly. Allows the patient to reach monthly maintenance injections quicker.
For most patients, the final dose received during CIT will be repeated for the first post-CIT injection the week after.
For patients who experienced a systemic reaction during CIT, the first post-CIT dose will be lowered.
Following CIT, the regular IT schedule will be followed going forward. Generally if you tolerate the whole protocol you will continue on weekly injections for another 3-4 weeks, then we can proceed to every other week shots, followed by every 3 week shots, then finally every month.
