While they don’t directly hurt you, house dust mites can be a big problem because many people are allergic to them.

What is allergy immunotherapy for house dust mite allergies?

Allergy immunotherapy (im-mu-no-ther-a-py) is a type of prescription medicine used to treat the root cause of allergies. It is made of very small doses of what you are allergic to (known as an allergen). Over time, allergy immunotherapy can make you less sensitive to the allergen. Allergy immunotherapy has two main forms that have been approved by the FDA:

  • Tablets that people with allergies place under their tongues every day at home (after taking the first dose in a health care provider's office)
  • Shots that allergy specialists give people with allergies approximately once a week to once a month
