What Are Allergy Shots? Defining Allergy Shots

What are allergy shots?

Allergy shots, a type of allergy immunotherapy, are a treatment for allergies that involve injecting small doses of allergens into the body over time to desensitize the immune system.

How do allergy shots work?

Allergy shots work by exposing the immune system to small amounts of allergens, allowing it to gradually build up a tolerance and become less reactive to those allergens over time.

Who are the best candidates for allergy shots?

Allergy shots are typically recommended for people with severe allergies or those whose symptoms are not well-controlled with medication.

Are there any risks associated with allergy shots?

The most common side effects of allergy shots are local reactions such as swelling, redness, and itching at the injection site. In rare cases, serious allergic reactions can occur.

How long does it take for allergy shots to start working?

It can take several months to a year or more for allergy shots to start working, and regular ongoing treatment is usually needed to maintain the benefits. Allergy shots usually take 3-5 years of treatment to result in long-term changes to the immune system.

How long do allergy shots last?

Allergy shots can provide long-lasting relief from allergy symptoms even after the treatment has stopped. Some people may experience complete relief, while others may need ongoing treatment.

Are allergy shots safe?

Allergy shots are generally safe, but like any medical treatment, they carry a risk of side effects. The most common side effects are local reactions at the injection site, but more severe reactions can occur. Allergy shots are administered at a doctor’s office due to the risk of severe allergic reactions.

Who should not receive allergy shots?

People with certain medical conditions, such as severe asthma or heart problems, may not be good candidates for allergy shots. Additionally, children under five years old are typically not given allergy shots.
