Allergy Shot Cost: What You'll Pay and How to Estimate It

What You Are Paying For

Allergy shots, also called subcutaneous immunotherapy (SCIT), work by injecting small, gradually increasing amounts of the allergens you react to. ACAAI calls them the most commonly used and most effective form of allergy immunotherapy, and they can treat reactions to trees, grass, weeds, mold, house dust, animal dander and insect stings (ACAAI). The total cost builds from several pieces:

• The first visit and testing. Before starting, an allergist confirms your triggers with skin or blood testing. See our allergy testing guide and skin prick vs. blood test comparison for what to expect.
• The allergen extract. Your shot mix is built from your test results, so a person allergic to several pollens, dust mites and a pet may have a more complex mix than someone allergic to one grass.
• The injection visits. Shots are given in an allergist’s office because there is a small risk of a severe allergic reaction shortly after an injection (ACAAI). Each of those visits may come with its own charge or copay.
• Follow-up visits. Periodic check-ins with the allergist to review how treatment is going.

Ask the allergist’s office how each piece is billed, then check those services against your plan.

Why the Schedule Matters More Than the Price of One Shot

Allergy shots are a marathon. According to ACAAI, injections may be given once a week, sometimes more often, for about seven months. After that, they can be given every two weeks, and eventually every four weeks. Treatment usually lasts three to five years, sometimes longer (ACAAI).

That schedule means the number of visits adds up. Using ACAAI’s timeline, here is a rough way to think about it:

• Year one: about 30 weekly visits during the roughly seven-month build-up, then every-other-week visits for the rest of the year, for roughly 40 visits.
• Each later year: about 13 visits a year at every four weeks, up to about 26 a year at every two weeks.
• Full course: roughly 65 visits over three years at the low end, up to about 145 over five years at the high end.

These counts are estimates built from the general schedule, not a promise. Your allergist may adjust the pace based on how you tolerate each dose. Still, the point stands: the cost of allergy shots is mostly the cost of showing up many times, so the per-visit amount you owe matters a lot.

How Insurance Changes What You Pay

Allergy shots are a medical treatment, so for most people the bill runs through health insurance. Three plan features decide most of what you pay:

• Deductible. This is what you pay for covered services before your plan starts to pay. With a $2,000 deductible, for example, you pay the first $2,000 of covered services yourself. Some plans have separate deductibles for certain services, like prescription drugs (HealthCare.gov).
• Copayment. A fixed amount you pay for a covered service, such as $30. Copays can differ for specialists, labs and drugs within the same plan (HealthCare.gov).
• Coinsurance. A percentage of the cost, such as 20%, that you pay after meeting your deductible. If your plan’s allowed amount for a visit is $100 and your coinsurance is 20%, you pay $20 once the deductible is met, but the full $100 before it is met (HealthCare.gov).

Timing can matter too. Year one has the most visits, so if your deductible resets each plan year, starting shots early in your plan year may mean more of the expensive build-up phase falls into a single deductible period. Ask your insurer whether shots, the extract and office visits are covered, whether they need prior approval, and whether your allergist is in your network.

Do Allergy Shots Pay for Themselves?

Several large studies suggest that, for many people, allergy shots can lower total health care spending. Researchers analyzed Florida Medicaid claims for children newly diagnosed with allergic rhinitis. Over 18 months, children who received allergy shots had lower median total health care costs than matched children who did not ($3,247 vs. $4,872), along with lower outpatient and pharmacy costs. The difference showed up within three months of starting shots (Hankin et al., 2010).

A follow-up study looked at nearly 5,000 adults and children who started allergy shots and more than 19,000 matched patients who did not. Those receiving shots had 38% lower mean 18-month health care costs ($6,637 vs. $10,644). The savings were 30% for adults and 42% for children, and they began within three months (Hankin et al., 2013). ACAAI similarly notes that research shows allergy shots reduce health care use and costs from prescription medicines, office visits and hospitalizations (ACAAI).

Keep these results in context. They describe overall health care costs in a Medicaid population, mostly paid by the program, not the copays a person with private insurance sees on a statement. They are also observational studies, so people who chose shots may have differed from those who did not. Still, they suggest that the upfront cost of shots can be offset by fewer medicines, visits and hospital stays over time.

Allergy Shots vs. Allergy Tablets: Cost Trade-Offs

Sublingual immunotherapy (SLIT) tablets dissolve under the tongue at home instead of being injected in a clinic. The only forms approved by the FDA are tablets for ragweed, northern pasture grasses such as timothy, and dust mites. They are taken anywhere from three days a week to daily, and treatment may continue for three years or longer (ACAAI). That can cut down on travel and time off work.

The trade-offs:

• One allergen per tablet. Most people with allergies react to more than one thing. Shots can cover several allergens at once, while each tablet treats a single allergen (ACAAI).
• Drops are different. Allergy drops are not FDA-approved and are used off-label in the United States. ACAAI notes they are not covered by most insurance, Medicare or Medicaid (ACAAI).
• Tablets are a prescription drug. Your cost depends on your pharmacy benefit, which may have its own deductible (HealthCare.gov).

For details on the tablets for specific pollens, see our guides to grass pollen allergy treatment and ragweed allergy treatment.

Costs That Are Easy to Overlook

• Time. Travel, time off work and any observation period your clinic requires after each injection add up over dozens of visits.
• Missed doses. Ask how your allergist handles gaps in the schedule, since falling behind can mean extra visits.
• Stopping early. The lasting benefit comes from finishing the course. Shots can have a lasting beneficial effect well after therapy is completed (ACAAI), so quitting early may leave you paying for treatment without getting its full value.
• The medicines you already buy. Count what you spend now on antihistamines, nasal sprays and doctor visits. Our comparisons of Zyrtec vs. Claritin vs. Allegra and Flonase vs. Nasacort vs. Rhinocort can help you weigh everyday options.

Questions to Ask Before You Start

• Which allergens will be in my shots, and how many vials or mixes will I need?
• How are testing, the extract and each injection visit billed?
• What build-up schedule do you use, and do you offer a faster one?
• How long will I need to wait after each shot?
• Is a tablet a reasonable option for my allergies, and would it cost less under my plan?

When Allergy Shots Make Sense

Shots are often worth a closer look if your symptoms last for much of the year, medicines are not controlling them well, or you would rather not rely on daily medicine for decades. Allergy shots can also help allergic asthma by relieving the allergic reactions that trigger asthma episodes and reducing the need for asthma medicines (ACAAI).
