Immunotherapy Drugs for Allergy

Immunotherapy is carefully timed and gradually increased exposure to allergens, particularly those that are difficult to avoid, such as pollens, dust mites and molds. The goal is to train the body's immune system not to react to these allergens. Immunotherapy may be used when other treatments aren't effective or tolerated.

Immunotherapy drugs: allergy shots
Immunotherapy may be administered as a series of shots, usually one or two times a week for three to six months. This is followed by a series of less frequent maintenance shots that usually continue for three to five years.

Sublingual immunotherapy drugs for allergy
With this type of immunotherapy, an allergen-based tablet was placed under the tongue (sublingual) and allow it to be absorbed. This daily treatment has been shown to reduce runny nose, congestion, eye irritation and other symptoms associated with hay fever. It also improves asthma symptoms and may prevent the development of asthma. SLIT tablets contain extracts from pollens of different types of grass, including the following:
Short ragweed (Ragwitek)
Sweet vernal, orchard, perennial rye, Timothy and Kentucky blue grass (Oralair)
Timothy grass (Grastek)
The drug usage and dosage in immunotherapy are related to the individual, So patients should negotiate with the doctors to have a better treatment.
