Advantages of Allergy Drops (Sublingual Immunotherapy)

Allergy Drops


Since you can administer them at home, allergy drops, or Sublingual Immunotherapy (SLIT), avoid taking time off from work or school for regular office visits to your Texas allergist required by shots. This is convenient for people who travel and cannot get to the doctor’s office for regular allergy shot visits. This method is also pain-free.


The cost of allergy drops is comparable to a co-pay for shots and medications for most patients, but stops after five years, while other medication costs could be life-long. Each patient is evaluated on their individual circumstances, their insurance coverage, medical history and reactions.

Safe for Most Patients:

SLIT is an option for patients as young as two years old all the way to senior citizens. Our Texas patients have an easier time with allergy drops, and usually produce fewer undesirable reactions than allergy shots. Most patients miss fewer doses, as well, which helps with the treatment process. SLIT also offers a better safety profile. The occurrence of anaphylaxis incident is only three times per million. Texan allergy has had no reports of severe reactions to allergy drops using our protocol. SLIT is all-natural – unlike medications – and is made from simple extracts of pollens, dusts, molds, and pet dander.


In the latest meta-analysis, executed by the distinguished Cochrane Review (2009), more than 2300 patients on sublingual immunotherapy had a considerable decrease in symptom scores and the need for medication for allergies and asthma with no harsh reactions or anaphylaxis. Allergy drops are endorsed by the World Health Organization and the ARIA (Allergic Rhinitis and it Impact on Asthma) guideline. SLIT eliminates allergic reactions instead of masking symptoms as medications do. This treatment is effective at treating allergies because it is applied daily and it typically has a quicker onset of action (within four weeks). Allergy drops result in less adverse reactions than allergy shots.

The idea behind any kind of immunotherapy, including allergy drops and allergy shots, is to expose the body to a manageable portion of allergy-causing substances. Over several months, those concentrations will expand and a decrease in symptoms will occur.
Allergy Drops have been used for over 100 years, and used under the tongue.
There is a large amount of scientific evidence from the past 30 years
that shows how effective and safe SLIT is.
The majority of patients will experience fewer symptoms and will begin building immunity within weeks of starting their allergy drop treatments. For some patients, it will require a few months before they feel the effect of the treatment. Our Texas allergists use a dosing schedule customized to your specific allergies. Depending on preference, each patient is able to decide to take their entire daily dose at once or to split it up into two or three times during the day.

Potential Side Effects

There are potential adverse reactions and side effects sometimes associated with allergy drops. They are nearly always very mild and usually do not warrant any treatment. Upwards of 135,000 patients over the past 40 years with our protocol have had no reports of severe reactions.

Most reported reactions complain of itching or tingling in the mouth and mild swelling under the tongue. This can occur in up to 40% of patients during the initial few days of therapy. We recommend treating with an antihistamine and keeping on the same dose of drops every day until the reaction no longer occurs.

Other adverse reactions are uncommon but may include wheezing, nausea and stomach pain in patients who suffer from asthma. Severe allergic reactions such as anaphylaxis are extremely rare and much less common than with allergy shots. Therefore, allergy drops are safe to be given at home.

Patients with asthma or anyone taking beta blockers can safely use allergy drops. As always, asthmatics should take their medications to keep their asthma under control, but the chance of significant asthma exacerbation is far less when using drops than when using shots.

Learn More About Allergy Drops

Patients currently taking allergy shots can switch to drops (and vice versa). Prior to switching, we will need to repeat the allergy testing process.
