There are two types of desensitization treatments, one subcutaneous and one sublingual. Subcutaneous injections are slightly more expensive, around$30,000, while sublingualization is relatively inexpensive, usually around$4,000. Subcutaneous injection is similar to vaccination, starting with a weekly injection, later a monthly injection, lasting for 2-3 years, so that the patient produces antibodies against allergens, thus achieving the role of allergens; sublingualization is a kind of mite proteins, the operation is simple, and is not prone to acute adverse reactions, so it is easy to be accepted by the patient.
