In-Office Allergy Testing & Needle-Free Sublingual Immunotherapy

Eliminate North Texas seasonal allergy misery permanently. Painless in-office scratch testing identifies your specific airborne triggers (mountain cedar, oak, ragweed, dust mites, molds) with daily at-home allergy drops.

North Texas is notorious for some of the most aggressive airborne allergens in the country, especially winter Mountain Cedar, spring Oak pollen, and fall Ragweed. Antihistamine pills and nasal sprays only mask symptoms temporarily and often cause drowsiness. Our clinical allergy center provides comprehensive, pain-free environmental scratch testing and customized sublingual immunotherapy (SLIT) drops taken under the tongue at home, desensitizing your immune system for permanent symptom freedom.

Who is a good candidate

  • Adults and children suffering from chronic sneezing, congestion, sinus pressure, or itchy watery eyes
  • Patients experiencing severe seasonal "Cedar Fever" or persistent year-round allergic rhinitis
  • Individuals who want to avoid weekly allergy shots and prefer painless, at-home sublingual drops
  • Patients with allergy-induced asthma or recurrent sinus infections

Treatment protocol

  • Step 1: 15-Minute In-Office Percutaneous Scratch Test — Application of tiny, painless antigen droplets to the forearm to identify exact environmental reaction profiles in 15 minutes.
  • Step 2: Custom Antigen Serum Formulation — Compounding individualized allergen extracts specifically concentrated to target your unique immune sensitizations.
  • Step 3: At-Home Sublingual Drop Dosing (SLIT) — Self-administration of two drops under the tongue daily in the comfort of your own home with zero clinic visits for injections.

Frequently asked questions

How does sublingual immunotherapy (allergy drops) compare to traditional allergy shots?

Allergy drops contain the same FDA-approved antigens as allergy shots, but are taken under the tongue at home. Because the sublingual route carries an exceptionally safe profile with virtually zero risk of anaphylaxis, you never have to sit in a clinic waiting room after dosing.

How soon will I notice improvement in my allergy symptoms?

Most patients experience significant symptom reduction within 8 to 12 weeks of beginning sublingual immunotherapy, with lasting desensitization achieved over a standard 3-year maintenance protocol.
