Allergen Drops for Sublingual Administration

SHARE

HAL Allergy offers allergen drops that can be administered by applying a few drops under the tongue (sublingual immunotherapy). Sublingual products are manufactured from standardized allergen extracts formulated in glycerol. Glycerol improves the dosing of the product by enhancing the stickiness in the mouth, and is a stabilizer of the allergen extracts.
