Allergy Shots: Uses, Side Effects, Safety and More

Allergy Shots

What Are Allergy Shots?

Allergy shots, also known as allergen immunotherapy or allergy desensitization, are a treatment option for individuals with severe allergies. They involve injecting small doses of allergens (substances that trigger allergic reactions) under the skin over a period of time. The goal of allergy shots is to gradually desensitize the immune system to specific allergens, thereby reducing the severity of allergic reactions over time.

Allergy Shots: Uses

Allergy shots are primarily used to treat allergic rhinitis (hay fever) and allergic asthma. They can also be effective in managing allergies caused by insect bites or stings, as well as certain types of allergic dermatitis.

Common Side Effects of Allergy Shots

  • Redness, swelling, or itching at the injection site
  • Mild allergic reactions such as sneezing, nasal congestion, or itching
  • Localized reactions such as hives or rash
  • Tenderness or soreness at the injection site
  • Mild headache
  • Fatigue or drowsiness
  • Mild flu-like symptoms, such as low-grade fever, achiness, or malaise

Rare Side Effects of Allergy Shots

  • Severe allergic reactions (anaphylaxis) characterized by difficulty breathing, wheezing, swelling of the face or throat, rapid heartbeat, dizziness, or loss of consciousness
  • Asthma exacerbation or worsening of asthma symptoms
  • Systemic reactions such as widespread hives, itching, or swelling
  • Cardiovascular reactions such as rapid or irregular heartbeat
  • Anaphylactic shock, a severe, life-threatening allergic reaction that requires immediate medical attention
  • Serious infections, although this risk is extremely low with properly administered allergy shots
  • Injection site infections or abscesses, particularly if proper hygiene measures are not followed

Allergy Shots: Safety for Pregnant Women and Children

The safety of allergy shots for pregnant women and children is a topic that should be discussed with a healthcare professional. While there is limited research on the use of allergy shots during pregnancy, they are generally considered safe for pregnant women who have been receiving the treatment prior to becoming pregnant. As for children, allergy shots can be considered for those who are at least five years old and have severe allergies that significantly impact their quality of life.

Allergy Shots Recall

As of now, there have been no recalls specifically related to allergy shots. However, it is important to follow any updates or notifications from the manufacturer or healthcare provider regarding the safety or effectiveness of the specific allergen extracts used in the shots.

Allergy Shots FDA Approval

Allergy shots and the allergen extracts used in them are regulated by the U.S. Food and Drug Administration (FDA). The FDA ensures that these treatments meet certain standards for safety and effectiveness. It is crucial to receive allergy shots from a licensed healthcare provider who adheres to FDA guidelines.

Why Are Allergy Shots Prescribed?

Allergy shots are prescribed to alleviate the symptoms of allergies and improve the quality of life for individuals with severe allergic reactions. They are particularly beneficial for those who do not experience relief from other allergy medications or who want to reduce their dependence on these medications.

How Should Allergy Shots Be Used?

Allergy shots are administered by a healthcare professional in a controlled medical setting. The treatment typically involves two phases: the build-up phase and the maintenance phase. During the build-up phase, the dosage of allergens in the shots gradually increases until the target dosage is reached. The maintenance phase follows, during which the shots are given at regular intervals to maintain the desensitization effect.

Other Uses for Allergy Shots

In addition to their primary use in treating allergic rhinitis and asthma, allergy shots have shown promise in managing other allergic conditions, such as allergic conjunctivitis (eye allergies) and certain types of food allergies. However, further research is needed to establish their effectiveness in these areas.

Special Precautions for Allergy Shots

Before starting allergy shots, it is important to inform your healthcare provider about any existing medical conditions, medications you are taking, or any previous severe allergic reactions you have experienced. Your healthcare provider will determine if allergy shots are suitable for you and if any special precautions need to be taken.

Storage and Disposal of Allergy Shots

Allergy shots should be stored as instructed by your healthcare provider or the manufacturer. It is important to keep them out of reach of children and dispose of any unused or expired shots properly. Your healthcare provider can provide guidance on the proper disposal methods.

In Case of Emergency/Overdose

In the event of an emergency or overdose related to allergy shots, it is crucial to seek immediate medical attention. Contact your local emergency services or go to the nearest emergency room.

Other Important Information About Allergy Shots

It is essential to follow the prescribed schedule for allergy shots and attend all appointments as recommended by your healthcare provider. Missing doses or discontinuing treatment prematurely may reduce the effectiveness of the therapy. Additionally, it may take several months or even years of treatment to achieve the desired results.

While allergy shots are generally safe and effective, they may not be suitable for everyone. It is important to consult with a healthcare professional to determine if this treatment is appropriate for your specific allergies and medical history.
