Cost, Benefits, Side Effects & What to Expect
Allergy shots, also known as allergen immunotherapy, are a long-term treatment designed to reduce or eliminate allergic reactions. If you suffer from persistent allergies that don’t respond well to medication, allergy shots may offer lasting relief.
In this guide, we’ll cover how allergy shots work, their cost, benefits, risks, and whether they’re worth it.
What Are Allergy Shots?
Allergy shots are a form of immunotherapy treatment that helps your immune system become less sensitive to allergens like:
- Pollen (grass, trees, weeds)
- Dust mites
- Mold
- Pet dander
- Insect stings
Small amounts of these allergens are injected into your body over time, helping your immune system build tolerance.
How Do Allergy Shots Work?
Allergy shots work in two phases:
1. Build-Up Phase
- Injections are given 1–2 times per week
- Gradually increasing allergen doses
- Lasts about 3 to 6 months
2. Maintenance Phase
- Injections every 2–4 weeks
- Continues for 3 to 5 years
- Provides long-term allergy relief
Over time, your immune system becomes less reactive, reducing symptoms significantly.
Benefits of Allergy Shots
Allergy shots are considered one of the most effective treatments for chronic allergies.
Key Benefits:
- Long-term symptom relief
- Reduced need for allergy medications
- Improved quality of life
- May prevent new allergies from developing
- Can reduce risk of asthma in children
For many patients, allergy shots provide lasting results even after treatment ends.
Allergy Shots Cost
The cost of allergy shots can vary depending on location, provider, and insurance coverage.
Typical Costs:
- Initial testing: $100 – $1,000
- Per injection: $20 – $100
- Annual cost: $1,000 – $4,000
Insurance Coverage
Many health insurance plans cover allergy shots, especially when deemed medically necessary. Always check with your provider for details on:
- Co-pays
- Deductibles
- Coverage limits
Are Allergy Shots Safe?
Allergy shots are generally safe when administered by a qualified healthcare professional.
Common Side Effects:
- Redness or swelling at injection site
- Mild itching
- Sneezing or nasal congestion
Rare but Serious Reactions:
- Anaphylaxis (severe allergic reaction)
- Difficulty breathing
- Swelling of throat
Because of this risk, patients are usually monitored for 20–30 minutes after each injection.
Who Should Consider Allergy Shots?
Allergy shots may be recommended if you:
- Have severe or year-round allergies
- Don’t respond well to medications
- Want to avoid long-term drug use
- Experience side effects from allergy medications
They are commonly used for allergic rhinitis (hay fever) and allergic asthma.
How Long Do Allergy Shots Take to Work?
Some patients notice improvement within 3–6 months, but full benefits typically appear after 12–24 months.
Consistency is key missing doses can reduce effectiveness.
Allergy Shots vs Allergy Drops
An alternative to shots is sublingual immunotherapy (allergy drops or tablets).
| Feature | Allergy Shots | Allergy Drops |
|---|---|---|
| Administration | Injection | Under the tongue |
| Frequency | Clinic visits | At home |
| FDA Approval | Yes | Limited (varies by region) |
| Cost | Higher upfront | May vary |
Shots are generally considered more effective for multiple allergens.
Tips Before Starting Allergy Shots
