Allergen immunotherapy, or desensitization, is a treatment for allergies that aims to change how
your body reacts to allergens by gradually exposing you to them, either through injections
(subcutaneous immunotherapy) or sublingual tablets/drops.

Here’s a more detailed explanation:

How it works:

Immunotherapy works by exposing the body to increasing doses of the allergen over time, allowing
the immune system to become less sensitive and develop tolerance.

Types of Immunotherapy:

• Subcutaneous Immunotherapy (SCIT): Involves regular injections of allergen
  extracts under the skin.
• Sublingual Immunotherapy (SLIT): Involves taking allergen extracts as tablets or
  drops under the tongue.

What it treats:

Immunotherapy can be effective for allergies to pollens, dust mites, pet dander, and insect venom,
as well as allergic rhinitis, allergic asthma, and conjunctivitis.

Benefits:

• Reduces allergy symptoms.
• May prevent new allergies.
• Can help control asthma by interrupting the allergic response.
• Can lead to long-term relief of allergy symptoms.

Duration of treatment:

Immunotherapy is a long-term treatment, usually lasting several years (3-5 years).

Risks:

While generally safe, immunotherapy can cause mild side effects like redness, swelling, or itching at
the injection site, or in some cases, more serious reactions like anaphylaxis.

Important Note:

Immunotherapy should only be administered under the supervision of a qualified healthcare
professional in a facility equipped to handle potential allergic reactions.
