Advantages of Allergy Drops (Sublingual Immunotherapy)

Allergy Drops


Since they can be administered at home, allergy drops, or Sublingual Immunotherapy (SLIT), avoid taking time from work or school for weekly office visits to your Texas allergist that are necessary 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.


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 reactions, history and insurance coverage.

Safe for Most Patients:

Allergy shots are available to patients from age two and thereon up to seniors. Our Texas patients have an easier time with allergy drops, and usually have fewer adverse reactions than shots. Fewer patients miss doses of allergy drops, 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. We have had no reports of reactions of a severe nature while using our allergy drop protocol. All-natural, unlike medications, SLIT is 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 being treated with sublingual immunotherapy had a considerable decrease in symptom scores and medication use for both allergies and asthma with no severe reactions or anaphylaxis. Allergy drops are endorsed by the WHO (World Health Organization) and the Allergic Rhinitis and its Impact on Asthma (ARIA) guideline. SLIT eliminates allergic reactions instead of masking symptoms as medications do. This treatment is effective at treating allergies because it is used daily and its onset of action can be faster (within four weeks). Allergy drops produce fewer unfavorable reactions than shots.

The concept behind immunotherapy treatments, which includes allergy shots and drops, is to expose the body to small amount of substances that cause allergies. Over a several month period, the number of those concentrations will grow and a decrease in symptoms will occur.
Allergy drops have been used for more than a century.
Over the last 30 years, there is much scientific evidence
that shows how effective and safe SLIT is.
Most patients will experience fewer symptoms and start to build up immunity within a few weeks of the beginning of their treatment with allergy drops. For some, it will require a few months before they feel results from their treatment. Our Texas allergists use a dosing schedule customized depending on the specific allergies. It is possible to take your entire daily dose at once 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 almost always very mild and treatment is rarely required. More than 135,000 patients through the last 40 years using our protocol have had no severe reactions.

Of patients who report a reaction, they typically 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. Our recommendation is treating with an antihistamine and keeping on the same dose of drops every day until the reaction no longer occurs.

Some other adverse reactions, though uncommon, may include wheezing, nausea and stomach ache in asthmatic patients. Severe allergic reactions, such as anaphylaxis, are extraordinarily rare and are much less common than with treatment with allergy shots. Therefore, allergy drops may be given at home safely.

Any patients with asthma or patients requiring the use of 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 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). Before switching, we will usually want to repeat your allergy testing. If you are interested in treatment with allergy drops, or want to request more information, call our office or email us to schedule a visit with our Texas allergist or ask any questions about current pricing or other information.
