Allergy shot

Allergy Shot

An allergy shot, also known as immunotherapy, is a long-term treatment that decreases symptoms for many people suffering from allergic rhinitis, allergic asthma, conjunctivitis (eye allergy) or stinging insect allergy. It works by reducing sensitivity to allergens, substances that trigger an allergic reaction.

Overview

Allergy shots are usually recommended for individuals with severe allergies or those who experience allergy symptoms more than three months a year. They are also a viable option for people who cannot avoid specific allergens or for those who do not respond well to antihistamines or other allergy medications.

Procedure

The procedure for an allergy shot involves injecting small doses of allergens into the patient's body. The allergens used in the shots are those to which the patient is allergic. The doses are gradually increased over time, allowing the immune system to become less sensitive to the allergen. This process is known as desensitization.

Benefits

The primary benefit of allergy shots is the reduction of symptoms over time. Some people may achieve complete relief from their allergy symptoms, while others may find that their symptoms are reduced, making them easier to manage.

Risks and Side Effects

While allergy shots are generally safe, they do carry some risks. The most common side effects are redness, swelling, or irritation at the injection site. In rare cases, a severe allergic reaction called anaphylaxis can occur.
