What are allergy shots?

Allergy shots are a form of immunotherapy that triggers your body’s immune response to treat certain types of allergies. The immune system is your body’s natural defense mechanism. When you have an allergy, your immune system has an abnormal reaction to a harmless substance, like pollen or certain foods.

An allergy shot gradually exposes your immune system to an allergen (the substance to which you’re allergic) to reduce negative reactions, such as wheezing, hives, or watery eyes. Dr. Fowler typically recommends allergy shots if you have moderate to severe allergies that haven’t responded well to other treatments, like antihistamines.

How do allergy shots work?

Allergy shots work similarly to vaccines. They leverage your natural immune function to increase your tolerance to allergens. Like vaccines, allergy shots contain small amounts of an allergen. Dr. Fowler injects these shots into your body to expose you to the allergen without triggering severe symptoms.

Over time, your body adjusts to the allergen, which reduces your symptoms. Some individuals overcome particular allergies entirely after building immunity, while others only experience mild symptoms.

What does getting allergy shots involve?

Dr. Fowler typically administers allergy shots in three phases: initial, buildup, and maintenance. During the initial phase, Dr. Fowler gives you one to two injections a week. This process helps you build a tolerance to the allergen without experiencing uncomfortable side effects. Once you reach the maintenance phase, he may administer your shots once a month or less.

How long do allergy shots take to work?

Allergy shots typically take a few months to a year to relieve uncomfortable symptoms, such as coughing, sneezing, and itching. The type and severity of your allergy can influence the length and frequency of your treatment.

Do allergy shots have side effects?

Most side effects of allergy shots are mild. Swelling, bruising, and redness at the injection site are common, but these effects typically subside within a few hours. In rare cases, hives, abdominal cramping, and nausea can occur.

As an allergy specialist, Dr. Fowler can develop an individualized allergy management plan that relieves your symptoms while minimizing uncomfortable side effects.
