Your drops are custom-made according to your allergies. They contain small doses of what you’re allergic to, such as dust mites, grass, ragweed, cat and dog dander, and tree pollens, among other allergens.
The ingredients used in immunotherapy drops are the same ones traditionally used in allergy shots. Non-active ingredients include glycerin, sodium bicarbonate, sodium chloride, and water. The allergen extracts used in Nectar prescriptions are phenol-free.
