Advantages of Allergy Drops (Sublingual Immunotherapy)

Allergy Drops


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


Cost of allergy drops is similar to co-pays for medications and shots of most patients, but stops after five years, while other medication costs could be indefinite. Each patient is judged on their unique circumstances, their medical history, reactions and insurance coverage.

Safe for Most Patients:

Allergy shots can be administered in patients as young as two years old and older. Allergy drops are easier for our Texas patients and have fewer adverse reactions than shots. Most patients miss fewer doses, as well, allowing them to not have to go back in their treatment process. A superior safety profile also accompanies Sublingual Immunotherapy. 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 molds, pet dander, pollens and dust.


The results shown in the latest meta-analysis, conducted by the well-known Cochrane Review (2009), more than 2300 patients being treated with sublingual immunotherapy had a significant reduction in symptom scores and medication use for both asthma and allergies with no harsh reactions or anaphylaxis. Allergy drops are endorsed by the World Health Organization (WHO) and the ARIA (Allergic Rhinitis and it Impact on Asthma) guideline. SLIT eliminates allergic reactions instead of masking symptoms as medications do. This method is effective for treating allergies because the patient uses it daily and the onset of action is generally quicker (within 4 weeks). Allergy drops have fewer adverse reactions than shots.

The concept behind immunotherapy treatments, which includes allergy drops and allergy shots, is to subject the body to a tiny amount of the substances that cause allergies. Over a several month period, there will be an increase in those concentrations 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 which clearly documents their effectiveness and safety.

Most patients undergoing SLIT will have fewer symptoms and begin to build immunity within a few weeks of starting allergy drop therapy. For some people, it may take up to several months to feel the effect of the treatment. Our Texas allergists will customize a dosing schedule according to your particular allergies. It is possible to take your entire daily dose at once or to take it at two or three different times throughout the day.

Potential Side Effects

There are potential adverse reactions and side effects are associated with treatment through allergy drops. They are typically very mild and usually do not warrant any treatment. Upwards of 135,000 patients over a period of 40 years using our protocol have had no severe reactions.

Most reported reactions complain of tingling or itching in the mouth or 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.

While uncommon, some of the other adverse reactions might include stomach ache, nausea and wheezing in patients who have asthma. Severe allergic reactions, such as anaphylaxis, are extraordinarily rare and are much less common than in patients taking allergy shots. For this reason, allergy drops can safely be given at home.

Any patients with asthma or those who are 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 using allergy drops as with allergy shots.

Learn More About Allergy Drops

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.
