The Science Behind Allergy Drops

Sublingual Immunotherapy

Sublingual immunotherapy is the medical term for allergy drops and is a safe and effective alternative to allergy shots. This method has been used in clinical practice and tested in research studies for the last 20 years. 

Allergy drops, work similar to allergy shots, and train your body to tolerate the triggers that cause your allergic reactions. The difference is that the same allergen extracts are placed under your tongue in a liquid drop instead of an injection. The drops work by exposing you to very small doses of what you’re allergic to. And when placed daily under your tongue, over time, your body builds a tolerance to the allergens, which reduces symptoms and ultimately provides permanent relief from allergies. Your clinician will work with you every step of the way to make sure

Personalized Care

Treatment length varies based on allergy severity and type but after 3 to 6 months of taking the drops daily, most patients experience a significant improvement in their allergy symptoms. For lasting immunity and permanent relief, our doctors recommend a full treatment period of 3 to 5 years to help you stay symptom-free. 

Allerpak offers patients sublingual immunotherapy with a custom formula tailored to what you’re allergic to -- like dust mites, grass, weeds, cat and dog dander, and tree pollens, among other environmental allergens. 

Allerpak’s approach is personalized: each patient is different and not everyone achieves the same result over the same time. We work with each patient individually to help them achieve the best results with sublingual immunotherapy.
