Cluster Therapy Q & A

What is cluster immunotherapy?

Cluster immunotherapy, or CIT, is an alternative way of doing allergy shots that helps patients reach their effective dose in a few weeks rather than the 3-6 months it takes to get to the same level with standard immunotherapy. When you get cluster immunotherapy, you’ll get 2-4 shots given 30 minutes apart, with each shot containing a higher dose of allergen.

You’ll have the same therapy one day each week until you reach your maintenance dose. For most patients it only takes 1-2 months, compared to 3-6 months for standard immunotherapy. After that, you’ll follow a maintenance schedule established by the doctors at North Texas Allergy & Asthma Associates.

What allergies can be treated with cluster immunotherapy?

Using cluster therapy to quickly reach a maintenance dose — which means you’ve received enough immunotherapy to prevent or reduce allergic reactions — may be recommended for patients with allergic asthma and others who are allergic to airborne allergens. This group includes allergies to dust mites, mold, pet dander, and pollens from grasses, trees, and weeds.

Cluster immunotherapy may also be considered for patients who are allergic to insect venom, especially if they’re highly sensitive to insect bites and stings, such as bee stings and ant bites. Before using cluster therapy for other types of allergies, the doctors must consider each person’s individual health and medical history to determine whether they’re good candidates for accelerated immunotherapy.

Is cluster immunotherapy safe?

Cluster immunotherapy is a safe procedure, but since you’ll get about a month’s worth of immunotherapy injections in just one visit, there’s a higher chance of having a reaction to the shots. To prevent or reduce your risk of a reaction, you’ll take medications such as antihistamines or corticosteroids in the days prior to your scheduled immunotherapy.

Patients also stay in the office during and after cluster immunotherapy so that the doctors and staff can closely monitor their health and provide immediate treatment in the event of a reaction. When you come in for each cluster immunotherapy appointment, be prepared to spend at least half a day at North Texas Allergy & Asthma Associates.
