What Is Immunotherapy?

Immunotherapy for allergies involves exposing individuals to larger amounts of allergens in an attempt to change the immune system response. This complete procedure aids the body in building tolerance, and eliminating the severity of allergic reactions.

There are several types of immunotherapy. Let us also discuss them.

Following are Immunotherapy Types:

• Subcutaneous Immunotherapy (SCIT): SCIT is alsoknown as allergy shots.
• Sublingual Immunotherapy (SLIT): allergen tablets or allergy drops thatare placed under your tongue for some time.

Types of Immunotherapy and Their Applications

Let us discuss in detail the Types of Immunotherapy and Their Applications

1. Subcutaneous Immunotherapy (SCIT):

Subcutaneous Immunotherapy also known as allergy shots. These are most common and effective form of allergy immunotherapy. This treatment changes the immune system of the individual, which can help in preventing the development of new allergies.

SCIT is effective for:

• Seasonal allergies
• Indoor allergens (e.g., dust mites, mold)
• Insect venom allergies

SCIT needs regular clinic visits and has a small risk of severe allergic reactions.

2. Sublingual Immunotherapy (SLIT)

Sublingual immunotherapy is an alternate way to treat allergies without injections. While tablets is the only FDA-approved sublingual therapy  and allergy drops are not FDA-approved. For people with multiple allergies, allergy tablets may not be the good option for them because they treat only one at a time. However allergy shots can treat various allergies at one time.

It is particularly effective for:

• Allergic rhinitis

• Egg
• Milk
• Tree nuts

4. Epicutaneous Immunotherapy (EPIT)

Epicutaneous Immunotherapy has been popular since last few years. EPIT is particularly suited for younger children. EPIT uses a skin patch to deliver allergens through the skin. EPIT typically involves applying a daily patch for a fixed number of hours, as determined by clinical protocol.

Research suggests that EPIT promises for safe, and long-term allergy management.

How Does Immunotherapy Work?

The immune system of allergy sufferers overreacts to the harmless things (like pollen or pets) causing an allergic reaction. Immunotherapy will gradually train your immune system not to react to these triggers.
