Allergy Drops

Advantages of Allergy Drops (Sublingual Immunotherapy)

Allergy Drops


Since they can be administered at home, allergy drops, or Sublingual Immunotherapy (SLIT), avoid time off work/school for regular weekly office visits to your Texas allergist that are required for allergy shots.
They are also very convenient for people who travel and cannot get to the doctor’s office for regular allergy shot visits. Also some may like the pain free administration.


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


SLIT can be started beginning at the age of two and older. Allergy drops are easier for our Texas patients and produce fewer undesirable reactions than allergy shots. Allergy drops are also easier for most patients to remember to take, which helps with the treatment process. SLIT also offers a better safety profile. The occurrence of anaphylaxis incident is only three times per million. We have had no reports of severe reactions to allergy drops using our protocol. Unlike medications, SLIT is all-natural – made from simple extracts of pollens, dusts, molds, and pet dander.


In the most recent meta-analysis, conducted by the well-known 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 asthma and allergies with no harsh reactions or anaphylaxis. Allergy drops are endorsed by the WHO (World Health Organization) and the ARIA (Allergic Rhinitis and it Impact on Asthma) guideline. More information

SLIT eliminates allergic reactions instead of masking symptoms as medications do. This treatment is effective at treating allergies because it is used daily and the onset of action happens quickly, usually within four weeks. Allergy drops result in less adverse reactions than allergy shots.

The design behind every kind of immunotherapy, including allergy drops and allergy shots, is to expose the body to a manageable portion of allergy-causing substances. After several months, there will be an increase in those concentrations and the symptoms will decrease.
Allergy drops (under-the-tongue included) have been used for more than one hundred years.
There is a large amount of scientific evidence from the past 30 years
which concludes that SLIT is both safe and effective.
Most patients will experience fewer symptoms and start to build up immunity within a few weeks of starting their allergy drop treatments. For some people, it might take several months to feel the effect of the treatment. Our Texas allergists will customize a dosing schedule to your particular allergies. You are allowed to take your entire daily dose at one time or to divide it into two or three servings.

Potential Side Effects

There are potential side effects and adverse reactions associated with allergy drops. They are nearly always very mild and do not necessarily require treatment at all.
At least 135,000 patients over a period of 40 years with our protocol have had no reports of severe reactions.

Of patients who report a reaction, they typically complain of either itching or tingling in the mouth, or some swelling under the tongue. These reactions occur during the first few days of treatment in up to 40% of all patients. We recommend 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 with asthma. Severe allergic reactions such as anaphylaxis are exceedingly rare and more uncommon than with allergy shots. Therefore, allergy drops are safe to be given at home.

Patients suffering from 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 when using allergy drops as treatment than with using allergy shots.

Patients currently taking allergy shots can switch to drops (and vice versa). Before switching, we will usually want to repeat your allergy testing. If you would like to treat your allergies with drops, or want to request more information, give us a call or email us to make an appointment with our Texas allergist or ask about pricing.
