Allergy Testing & Treatment

Trust the doctors at Acadian Allergy Center in Lafayette, LA for your allergy testing and treatment.

Residents of Southwest Louisiana are exposed to a broad spectrum of environmentally produced allergens. Pollen from trees and ragweed is often seen coating everything nearby in a yellow film. High humidity levels also produce mold-related allergens that can be troublesome. Allergies are rarely cured, but with proper diagnosis there are many medications, supplements, and treatment options available to help find relief from your symptoms.

We are a member of the American Academy of Otolaryngic Allergy. We attend continuing education courses regularly to keep our allergy staff educated with new information and industry innovations to benefit our patients. Recently, allergy testing methods have improved significantly and patients have more options than ever to relieve their allergy symptoms.

Cross Reactive Foods & Food Awareness

Please watch these foods the day before, day of and day after your allergy injection.

Certain foods have been reported as presenting problems during pollen season. Therefore, it may be advisable to rotate or eliminate the proven cross-reactive food from your diet during that specific time of the year. When the season is over, the foods may be introduced into the diet. Problems can occur shortly after exposure to the inhalant or up to several days later, thus making it difficult to track down the food culprit.

Remember, you are not allergic to these foods but consuming them can raise your overall allergy load and make you feel symptomatic. Many patients find that by simply watching these foods during their season, they feel better and are less reactive to their shots.

Sublingual Immunotherapy

More than 50 million residents of the United States suffer from allergies today, according to the Centers for Disease Control and Prevention (CDC). Allergies rank sixth as a cause of chronic illness in this country, costing $18 billion annually. Despite the prevalence of allergies, few people seek a permanent treatment for this condition in the form of immunotherapy. Immunotherapy is a process designed to pinpoint the source of allergies and alter the way the immune system responds to allergens, creating long-lasting relief from symptoms.

One of the primary ways to administer immunotherapy are through shots. Injections are used to expose the immune system to the reaction-causing substances in increasing amounts over time. This process increases the body’s tolerance to the allergen, significantly reducing symptoms like sneezing, wheezing, and itchy eyes. While immunotherapy typically takes years to complete, the positive benefits are long-lasting and can be permanent in some patients.

What is Sublingual Immunotherapy?
Sublingual immunotherapy or SLIT is a form of immunotherapy that involves placing drops of the allergen extracts under the tongue. This form of immunotherapy has been used for years in Europe and has recently increased use in the United States. A growing body of research supports both the efficacy and the safety of this treatment. This treatment is available at Acadian Allergy Center, offering our patients a convenient way to address their allergies when frequent shots are not a viable option.

Best candidates for Sublingual Immunotherapy?
We offer sublingual immunotherapy for the treatment of allergic reactions to dust mites, animal dander, cockroaches, mold, weeds, trees, and grass pollen. However, we do not use them for food, chemicals, and certain insect allergies. Patients that would benefit most from this include:

  • Off-shore workers
  • Residents of rural areas who are unable to get to a clinic or cannot drive
  • Severe asthmatics
  • People with needle phobias
  • Small children
  • It is also helpful for children who are afraid of needles.

How is the treatment done?
Sublingual immunotherapy begins with a test to identify the allergen that requires treatment. We offer both skin and blood draws for this purpose, depending on the suspected allergens. Once we receive the results, we can prepare customized vials for you to take home to administer daily. Drops are placed under the tongue via the metered-dose vial, ensuring that you receive the precise dosage required. 

The first three months mark the escalation stage, where the amount of the allergen is gradually increased to build the body’s tolerance. Once that is completed, the patient enters the maintenance phase, where the same dose is administered daily for three to four years. This extended treatment time allows the body to build up a strong immunity that will provide long-lasting relief from allergy-related symptoms.

At the beginning of the treatment, patients may continue to take allergy medication to control their symptoms as the benefits will not be seen immediately. However, most patients experience noticeable improvement within the first three to four months. Patients typically find they no longer require antihistamines to control their symptoms over time, as the drops build up sufficient immunity to keep symptoms at bay.

Risks & Side Effects
While sublingual immunotherapy has been shown to be a relatively safe treatment method, there are some side effects patients can experience with the therapy:

  • Itchy mouth
  • Mouth and tongue irritation
  • Nasal itching, sneezing
  • Asthmatic symptoms
  • Stomach upset

Side effects are rare, only occurring in a very small number of patients. In most cases, they are also temporary and subside on their own within a short time.

Why choose Sublingual Immunotherapy?
One of the primary reasons our patients choose sublingual immunotherapy is convenience. Patients will be able to take their pre-prepared drops from the comfort of their own home. With sublingual immunotherapy, you’ll require fewer office visits than you would if you underwent treatment like weekly injections. You do not need to take time off work or out of your busy schedule to maintain your treatment program. You can even travel with your drops.

Please note that sublingual therapy is a cash-pay only treatment, as is not covered by insurance, and cannot be used towards deductibles or Health Savings Accounts (HSAs). However, the cost of the treatment is very affordable and comparable to other types of allergy treatments. There is also savings since you do not have to come into the office more than once or twice annually throughout this process.

Sublingual immunotherapy drops are not for everyone. Your doctor will determine whether you are a candidate or if another treatment would be better suited to you. Contact the Acadian Allergy Center at 337-237-0779 today to schedule your appointment to discuss your options in person.
