Intralymphatic Immunotherapy (ILIT)

Intralymphatic immunotherapy (ILIT) is a specialized form of allergy immunotherapy designed to deliver allergens directly into lymph nodes, where immune responses are coordinated.


This targeted approach differs fundamentally from traditional subcutaneous allergy shots. AllerPoint provides intralymphatic immunotherapy (ILIT) for patients in Richmond, Northern Virginia, and surrounding regions seeking an alternative to traditional allergy shot.

These images illustrate how ultrasound is used during ILIT to locate superficial lymph nodes and guide accurate allergen delivery during treatment.

Your ILIT Treatment Journey

This section outlines the evaluation, planning, treatment, and monitoring steps involved in intralymphatic immunotherapy (ILIT), providing an overview of what patients can expect before, during, and after treatment.

1

Comprehensive Evaluation

  • Detailed allergy history review with Dr. Patel
  • Comprehensive symptom assessment
  • Review of completed allergy testing
  • Evaluation of prior allergy treatments and patient response
  • ILIT is recommended only when clinically appropriate
2

Personalized Treatment Planning

  • Identified environmental allergens
  • Severity and pattern of symptoms
  • Seasonal versus year-round exposure
  • History of prior immunotherapy
  • Preparation of allergy serum based on testing results
  • Use of FDA-approved allergen extracts commonly used in traditional allergy shots
3

Ultrasound-Guided Injection

  • Superficial lymph nodes identified using ultrasound
  • Experienced ultrasound technologist present during the procedure
  • Precise allergen injection performed by a board-certified allergist
  • Real-time imaging confirms accurate placement
  • Use of the thinnest needle possible to improve comfort
4

Post-Injection Monitoring

  • Patients are observed for one hour following each injection
  • Monitoring protocols are in place for all immunotherapy treatments
  • Patients are advised to avoid intense exercise before and after the procedure to limit localized irritation

FAQ

The following questions address common topics related to intralymphatic immunotherapy (ILIT), treatment eligibility, and what patients can expect throughout the evaluation and treatment process.

  • Cost is $1300 per injection, $3900 in total for three injections.
  • Booster injections needed within a year of first injection will be free of cost.
  • If an additional booster injection is needed years after the initial injections, patients will be charged for the injection.
  • Patients aged 12 years and older with a history of allergies
  • Individuals with seasonal or year-round allergies
  • Patients seeking a faster alternative to traditional allergy shots
  • Those tired of long-term dependence on allergy medications
  • A consultation is required to confirm eligibility for ILIT

Yes. ILIT uses low doses of allergen extract, and real-time ultrasound guidance ensures precise placement inside the lymph node. Most patients experience only mild, temporary soreness at the injection site.

Most visits take less than 15 minutes, followed by an hour of observation in the waiting room.

Patients may begin to feel relief after the third injection, with benefits continuing to build over time.

Studies suggest that relief can last for many years, similar to traditional allergy shots. Booster injections may be considered if symptoms gradually return.

Insurance plans do not typically cover ILIT because it is considered an off-label therapy. We accept multiple forms of payment, including HSA and FSA.

No. ILIT differs in both delivery method and treatment schedule. Traditional allergy shots are administered subcutaneously over several years, while ILIT involves targeted lymph node injections over a shorter period.

Yes. ILIT is designed as an alternative approach that reduces the long-term time burden associated with traditional immunotherapy.
