Immunotherapy Treatment Options

The purpose of immunotherapy is to decrease your sensitivity to allergy-causing substances, so that exposure to the offending allergen (pollen, mold, mites, and animal dander) will result in fewer and less severe symptoms. This does not mean that immunotherapy is a substitute for avoidance of known allergens or for the use of allergy medications, but rather is a supplement to those treatment measures.

Texas ENT Specialists offers three forms of immunotherapy;

  • Allergy Injections,
  • Asensa - Sublingual Drops
  • Conventional Therapy - Sublingual Drops.

Allergy Injections:

  • A mixture that is injected subcutaneously and consists of the allergens that were positive on your allergy test.
  • Allergy injections are given once a week (4 - 7 days) in the office setting.
  • Patients are required to wait in the office for 20 minutes after receiving their injections.
  • Allergy injections are not given to patients who are on a beta blocker or patients under the age of 8 years old.

Asensa - Sublingual Drops:

  • A mixture that is administered sublingually (under the tongue) that consists of the allergens that were positive on your allergy test.
  • Texas ENT Specialists feels this form of sublingual immunotherapy is more efficacious.
  • A Vial Safety Test is scheduled to begin Asensa Sublingual Drops.
  • During the escalation phase (build up), 2 metered dosing bottles will be utilized. Vial #1 is a build up bottle and will be administered for first 5 days. Vial #2 is the Maintenance bottle and will follow Vial #1. It will be administered for the next 7 weeks.
  • The first dose from Vial #1 will be administered in the clinic and then afterwards taken home for administration. Patients are required to wait in the office for 20 minutes after administering this sublingual drop.
  • Once the escalation phase has been completed you will have reached the maintenance phase. Your future maintenance metered dosing bottles will last for 8 weeks. (approximately)
  • After your initial Vial Safety Test appointment, you will order refills at www.texasent.com.

Conventional Therapy - Sublingual Drops:

  • A mixture that is administered sublingually (under the tongue) that consists of the allergens that were positive on your allergy test.
  • Conventional therapy is targeted for:
    • Pediatric Patients (under age 12).
    • Patients who are unable to tolerate the “Asensa” sublingual drops.
  • A Vial Safety Test is scheduled to begin Conventional Sublingual Drops. The first drop from escalation bottle #1 will be administered in the clinic and then afterwards taken home for administration. Patients are required to wait in the office for 20 minutes after administering this sublingual drop.
  • A twelve (12) week escalation dosing schedule is followed. During the escalation phase (build up), four metered dosing bottles are utilized, each one lasting 21 days.  You will receive all 4 build up bottles at the VST.
  • Once this has been completed you will have reached the maintenance phase. Your maintenance metered dosing bottle will last 84 days (approximately 12 weeks).
  • After your initial Vial Safety Test appointment, you will be required to order refills at www.texasent.com.

With all forms of Immunotherapy it can take 3 to 6 months before any relief of allergy symptoms is noted, and it usually requires 12 to 24 months for full benefits to be evident.

Immunotherapy is recommended for 3 - 5 years. Periodically throughout the duration of your treatment, you will schedule follow up visits with your doctor to check on your progress and reassess your treatment.

The allergy test results can be used for 1 year from the date that allergy testing was performed to start Allergy Injections, and for 3 years from the allergy testing date to start Sublingual drops.
