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 by shots. This is convenient for people who travel and are not able to get to the doctor’s office for continued allergy shot visits. Also, there is no pain from injections.


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 on a case to case basis, their insurance coverage, medical history and reactions.

Safe for Most Patients:

Allergy shots are available to patients from age two and thereon up to seniors. Allergy drops are usually easier for our Texas patients and have fewer adverse reactions than shots. Many patients also miss fewer doses, allowing them to not have to go back in their treatment process. SLIT also offers a better safety profile. The incidence of anaphylaxis to shots is three in one million. We have had no reports of severe reactions while using our allergy drop protocol. Unlike medications, SLIT is all-natural – made from simple extracts of pollens, dusts, molds, and pet dander.


In the most recent meta-analysis, executed by the distinguished 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 World Health Organization and the ARIA (Allergic Rhinitis and it Impact on Asthma) guideline. More information

SLIT stops allergic reactions instead of just hiding the symptoms, which is all 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 have fewer adverse reactions than shots.

The concept behind immunotherapy treatments, including allergy shots and drops, 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 a decrease in symptoms will occur.
Allergy Drops have been used for over 100 years, and used under the tongue.
Over the last 30 years, there is much scientific evidence
which concludes that SLIT is both safe and effective.
Most patients will experience fewer symptoms and begin to build immunity within a few weeks of starting their allergy drop treatments. For some patients, it may take up to several months to feel results from their treatment. Your dosing schedule will be customized by our Texas allergists to your particular allergies. Each patient is able 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 potential adverse reactions and side effects are linked with taking allergy drops. They are typically very mild and do not necessarily require treatment at all.
At least 135,000 patients through the last 40 years with our protocol have had no reports of severe reactions.

Most commonly, patients report 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 taking the same dosage of drops until the reaction no longer occurs.

Other adverse reactions are uncommon but may include wheezing, nausea and stomach pain in patients with asthma. Severe allergic reactions such as anaphylaxis are extremely rare and much less common than with treatment with allergy shots. Therefore, allergy drops are safe to be given at home.

Patients with asthma or patients using beta blockers can also be treated with allergy drops safely. 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 than when using allergy shots.

Learn More About Allergy Drops

Patients can switch from taking drops to shots, or from taking shots to drops. Prior to switching, we will need to repeat the allergy testing process.
