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 that are required by shots. This is convenient for patients who do not have a “normal” schedule and are not able to get to the doctor’s office for continued allergy shot visits. Also, there is no pain from injections.


Cost of allergy drops is in the range of the cost of a co-pay for medications and shots of most patients, but only lasts five years, while other medication costs could be life-long. Each patient is on a case to case basis, their reactions, history and insurance coverage.


SLIT can be started beginning at the age of two 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. Many patients also miss fewer doses, which is beneficial to the progress of the treatment. Sublingual Immunotherapy offers a superior safety profile. The occurrence of anaphylaxis incident is only three times per million. Texan allergy has had 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.


In the latest meta-analysis, conducted by the well-known Cochrane Review (2009), more than 2300 patients on sublingual immunotherapy had a significant reduction in symptom scores and the use of medication for allergies and asthma without severe reactions or anaphylaxis. Allergy drops are endorsed by the World Health Organization (WHO) and the ARIA (Allergic Rhinitis and it Impact on Asthma) guideline. Sublingual Immunotherapy eliminates allergic reactions, as opposed to masking symptoms like some medications do. This is an effective treatment for allergies because it is applied daily and its onset of action can be faster (within four weeks). Allergy drops result in less adverse reactions than allergy shots.

The idea behind any kind of immunotherapy, including allergy shots and allergy drops, is to subject the body to a tiny amount of the substances that cause allergies. Over several months, those concentrations will expand and a decrease in symptoms will occur.
Allergy drops (including under-the-tongue applications) have been used for more than 100 years.
Over the last 30 years, there is much scientific evidence
that shows how effective and safe SLIT is.
Most patients undergoing SLIT will have fewer symptoms and will begin building immunity within weeks of starting allergy drop therapy. For some people, it might take several months to feel results from their treatment. Our Texas allergists will customize a dosing schedule 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

Some potential adverse reactions and side effects are are associated with treatment through allergy drops. They are almost always very mild and do not necessarily require treatment at all.
More than 135,000 patients over the past 40 years with our protocol have had no reports of severe reactions.

Most commonly, patients report of itching or tingling in the mouth and mild swelling under the tongue. This occurs frequently (in up to 40% of patients) during the first days of treatment. Our recommendation is treating with an antihistamine and keeping the same dose of drops until the reaction stops occurring.

Other adverse reactions are uncommon but may include wheezing, nausea and stomach ache in patients who are asthmatic. Severe allergic reactions, such as anaphylaxis, are exceedingly rare and more uncommon than in patients taking allergy shots. For this reason, allergy drops can safely be given at home.

Patients who have 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 much less using allergy drops as with allergy 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.
