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 that are required by shots. This is convenient for patients who do not have a “normal” schedule are unable to make regular trips to the allergist's office for allergy shots. Also, there is no pain from injections.


Cost of allergy drops is in the range of the cost of a co-pay for average shots and medications, but lasts only 5 years, while the cost of others could be indefinite. Each patient is on a case to case basis, their history, reaction and insurance coverage.

Safe for Most Patients:

Allergy shots can be administered in patients as young as two years old and thereon up to seniors. Allergy drops are easier for our Texas patients and have less adverse reactions than allergy shots. Allergy drops are also easier for most patients to remember to take, which is beneficial to the progress of the treatment. SLIT also offers a better safety profile. Anaphylaxis incidents are much less likely to happen, occurring only three times per million. There have been no reports of reactions of a severe nature while using our allergy drop protocol. Unlike medications, SLIT is all-natural – made from simple extracts of dusts, molds, pet dander and pollens.


The results shown in the latest meta-analysis, executed by the distinguished Cochrane Review (2009), more than 2300 patients on sublingual immunotherapy had a significant reduction in symptom scores and medication use for both allergies and asthma without severe reactions or anaphylaxis. Allergy drops are endorsed by the World Health Organization (WHO) and the Allergic Rhinitis and its Impact on Asthma (ARIA) guideline. SLIT eliminates allergic reactions instead of masking symptoms as medications do. This is an effective treatment for allergies because the patient uses it 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 subject the body to a tiny amount of the substances that cause allergies. Over a period of several months the number of those concentrations will grow and the symptoms will decrease.
Allergy drops (including under-the-tongue applications) have been used for more than 100 years.
There is a large amount of scientific evidence from the past 30 years
which concludes that SLIT is both safe and effective.
The majority of patients will experience fewer symptoms and begin to build immunity within a few weeks of beginning their allergy drop therapy. For some people, it may take up to several months to start seeing effects from their therapy. Our Texas allergists will customize a dosing schedule according to your particular allergies. Each patient is able 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 side effects and adverse reactions sometimes associated with allergy drops. They are nearly always very mild and treatment is rarely required. More than 135,000 patients over the past 40 years using our protocol have had no severe reactions.

Most commonly, patients report 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. Our advice is treating with an antihistamine and maintaining the same dosage of drops until the reaction subsides.

Though uncommon, some other adverse reactions may include wheezing, nausea and stomach ache in patients who are asthmatic. Severe allergic reactions, such as anaphylaxis, are extraordinarily rare and are much less common than in patients taking allergy shots. Therefore, allergy drops are safe to be given at home.

Any patients with asthma or those who are 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 exacerbation is far less when using drops than when using shots.

Patients that currently take shots are able to switch to drops (and vice versa). We typically will repeat your allergy testing prior to switching treatments.
