Allergy drops, also known as sublingual immunotherapy (SLIT), are an effective and needle-free alternative to allergy shots. These drops work by desensitizing your immune system to allergens such as pollen, dust mites, pet dander and mold. Allergy drops are a liquid placed underneath the tongue that over time, reduces a patient’s sensitivity to specific allergens. Just like allergy shots, allergy drops will deliver long-term relief to allergens by steadily building up your immunity. Discover how allergy drops can help you take control of your allergy symptoms without the hassle of frequent office visits or injections.

How Allergy Drops Work
Effectiveness Over Time
- Daily Sublingual Dose: Allergy drops are placed under the tongue daily, allowing your immune system to gradually build tolerance to allergens.
- Gradual Dosage Increase: Your Allergy & ENT Associates board-certified allergist may recommend increasing the dosage gradually to prevent reactions.
- Long-Term Relief: With consistent use, allergy drops help reduce allergy symptoms and provide lasting relief.
By choosing allergy drop treatments, you are choosing to discover the root cause of your allergy symptoms. This treatment path won’t simply mask allergy symptoms with a temporary fix, but rather treat the problem at its source, ensuring lasting relief that increases over time.
Allergy Drops Vs. Allergy Shots
All cases are unique and can benefit from different treatment paths. Both allergy drops and allergy shots are highly effective, but depending on your individual needs, or level of tolerance to needles, you might have a preference. Discover which path to healing is best for you.
Allergy Drops
Allergy drops are taken at home under the tongue, meaning there are no needles or frequent office visits. Drops offer long-term relief for environmental allergies from the comfort and convenience of your home. When taken consistently, patients will experience sustained relief from allergy symptoms.
Allergy Shots
Allergy shots are given as an injection in a clinic, typically on a weekly basis. While shots require a commitment to regular office visits, they tend to provide quicker results for many patients. Like allergy drops, allergy shots provide long-term relief from chronic allergies by getting to the root cause of your allergy symptoms.

The Convenient Choice
Allergy drops are the convenient and needle-free option for those suffering from chronic allergies. Allergy drops are administered in the comfort of your home under the tongue, rather than with a shot in a clinic. Allergy drops are the right choice for those with busy schedules or a fear of needles.
What to Expect
Allergy drops are typically well-tolerated by most patients. Some possible minor side effects are swelling, sneezing or itchy, watery eyes. It’s important to take your drops at the same time each day and avoid eating or drinking for about thirty minutes both before and after. To experience the full benefit of allergy drops, it’s important to use them consistently for 6-12 months as they gradually build your immune system’s tolerance to certain allergens.
Allergy Drops for Children
Allergy drops are a safe and effective treatment option for children as young as two years old. They are easy to administer at home, making them an excellent choice for kids who dislike needles. Early allergy treatment can help prevent allergy symptoms from worsening over time.
