Know About Immunotherapy Or Allergy Shots

In some cases allergy medications can fail to adequately control a certain allergy symptom, it may also be not possible to simply avoid  a allergy trigger. During such situations, an allergist may recommend immunotherapy or ‘allergy shots’.

With a course of ‘allergy shots’ the patient will have fewer allergy symptoms and many cases, the allergy gets completely cured. Allergy shots are preferred to treat allergic rhino-conjunctivitis of the nose and eyes, allergic asthma and some insect sting allergies.

Difference from allergy medicines

Allergy medicines act only to cover-up allergic symptoms and prevent them only temporarily, on the other hand allergy shots treat the underlying allergy problem and even completely eliminate the symptoms. This is possible because on administering allergy shots, the body treats them like a vaccine and results in the production of infection fighting antibodies against the triggers like pollen, dust, mold or pet dander. The effects can last for years even after stopping the allergy shots and prevents forming of new allergies.

The method and dosage

Immunotherapy starts off with a small dose that will not cause any allergic reaction and gradually advanced to increase in dosage until the person is tolerant to the allergen. The injections are given once or twice a week and the treatment lasts anywhere from three to six months.

The risks involved

The risk involves an allergic reaction to the allergy shot leading to mild or moderate swelling and itching at the site of the shot. A large swelling may require adjustment in dosage.

Less common reactions include chest tightness, cough, wheezing, throat tightness, shock and rarely some are life threatening. It is thus advisable to remain in the physician’s office for around 30 minutes after each shot. Any reaction can easily be resolved with medicines such as injectable epinephrine and antihistamines.
