Insect Allergy

Insect allergies can trigger a wide range of symptoms, and it's essential to recognize them early for effective management. Common reactions to insect stings may include:

• Localized Reactions 
• Symptoms: Redness, swelling, and pain at the sting site.
• Severity: Usually mild and self-resolving.

• Systemic Reactions 
• Symptoms: Hives, itching, or swelling extending beyond the sting area.
• Severity: Can be more severe but not life-threatening in most cases.

• Anaphylaxis
• Symptoms: Difficulty breathing, throat swelling, dizziness, and rapid heartbeat.
• Action: Call 911 immediately if these symptoms occur.

What are the Causes of Insect Allergies?

Insect allergies are caused by an overreaction of the immune system to venom or saliva injected during stings or bites. San Antonio’s warm climate and active outdoor lifestyle increase the likelihood of encountering common allergy-triggering insects, such as:

• Bees
• Wasps
• Hornets
• Fire ants

Allergic reactions may range from mild discomfort to severe life-threatening responses.

Diagnosing an insect allergy begins with a review of your medical history, including any previous reactions to insect stings or bites. Your doctor may perform skin tests where small amounts of venom from different insects are applied to your skin to assess allergic reactions. 

In some cases, blood tests may also be conducted to detect specific antibodies related to insect venom. Combining these tests helps identify the exact allergen, enabling your doctor to develop an effective treatment plan tailored to your needs.

How is Anaphylaxis Treated?

For immediate relief, patients are offered the following insect bites and stings treatments:

Antihistamines :

These medications help relieve itching, hives, and swelling. Over-the-counter options, such as diphenhydramine (Benadryl), can be effective for mild reactions.

Corticosteroids :

Topical corticosteroids may be used to address the swelling or inflammation at the sting site. For more significant reactions, a healthcare professional might prescribe oral corticosteroids.

Epinephrine :

For patients at risk of anaphylaxis reaction, the specialist will recommend bringing an epinephrine auto-injector around. This medication can quickly counteract severe allergic reactions, and our compassionate team can help you learn how to use it and assist you with insect allergy symptoms!

For a more proactive approach, your specialist may also recommend these treatments to build tolerance and prevent future reactions: 

Avoidance Strategies :

Learning to identify and avoid potential triggers is vital. This may include staying away from certain areas during peak insect activity or wearing protective clothing outdoors.

Venom Immunotherapy :

This treatment involves regular injections of small amounts of venom to gradually desensitize the immune system. It can significantly minimize the likelihood of severe reactions from future stings and is particularly effective for those with a confirmed insect sting allergy.
