Sublingual immunotherapy (SLIT) is an alternative way to treat allergies without injections. An allergist gives a patient small doses of an allergen under the tongue to boost tolerance to the substance and reduce symptoms.
Currently, the only forms of SLIT approved by the FDA are tablets for ragweed, northern pasture grasses like timothy, and dust mites.
The safety and effectiveness of allergy drops is still being established by the FDA, and they are only used off-label in the United States. An allergist can evaluate your symptoms and provide you with the best options.
