Allergy Drops

Advantages of Allergy Drops (Sublingual Immunotherapy)

Allergy Drops


Since they can be administered at home, allergy drops, also known as SLIT, avoid taking time from work or school for weekly office visits to your Texas allergist that are required for allergy 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 similar to co-pays for the typical medications or shots of most patients, but only lasts five years, while the cost of others could be indefinite. Each patient is on a case to case basis, their medical history, reactions and insurance coverage.


Allergy shots can be administered in patients as young as two years old all the way to senior citizens. Allergy drops are easier for our Texas patients and produce fewer undesirable reactions than allergy shots. Most patients miss fewer doses, as well, which is beneficial to the progress of the treatment. A superior safety profile also accompanies Sublingual Immunotherapy. Anaphylaxis incidents are much less likely to happen, occurring 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 molds, pet dander, pollens and dust.


In the most recent meta-analysis, executed by the distinguished Cochrane Review (2009), more than 2300 patients on sublingual immunotherapy were found to have 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 and the ARIA (Allergic Rhinitis and it Impact on Asthma) guideline. SLIT stops allergic reactions instead of just hiding the symptoms, which is all some medications do. This treatment is effective at treating allergies because the patient uses it daily and it typically has a quicker onset of action (within four weeks). Allergy drops produce fewer unfavorable reactions than shots.

The design behind every kind of immunotherapy, which includes allergy drops and allergy shots, is to expose the body to a manageable portion of allergy-causing substances. Over a period of several months there will be an increase in those concentrations and the symptoms will dissipate.
Allergy drops have been used for more than a century.
There is a significant amount of scientific evidence from the last thirty years
that shows how effective and safe SLIT is.
Most patients will experience fewer symptoms and begin to build immunity within a few weeks of starting allergy drop therapy. For some, it will require a few months before they feel the effect of the treatment. Our Texas allergists will customize a dosing schedule depending on the specific allergies. Depending on preference, each patient is able to decide to take their entire daily dose at once or to take it at two or three different times throughout the day.

Potential Side Effects

Some side effects and adverse reactions are associated with allergy drops. They are usually very mild and treatment is rarely required. At least 135,000 patients over the past 40 years using our protocol have had no severe reactions.

Most commonly, patients report of tingling or itching in the mouth or mild swelling under the tongue. This commonly occurs during the first several days of treatment (in up to 40% of patients). We recommend treating with an antihistamine and taking the same dosage of drops until the reaction no longer occurs.

Some other adverse reactions, though uncommon, may include wheezing, nausea and stomach ache in patients who suffer from asthma. Anaphylaxis, and other severe allergic reactions, are extremely rare and much less common than with allergy shots. Because of this, allergy drops are safe to administer at home.

Any patients with asthma or anyone taking beta blockers can also 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 much less when using allergy drops as treatment than with using allergy shots.

Learn More About Allergy Drops

Patients that currently take shots are able to switch to drops (and vice versa). Prior to switching, we will need to repeat the allergy testing process.
