What Are Allergic Reactions?

An allergic reaction occurs when the immune system identifies a typically harmless substance—such as food, pollen, or certain chemicals—as a threat.

This triggers the release of histamines, which lead to symptoms ranging from mild discomfort to life-threatening conditions. Common symptoms include itching, swelling, rashes, sneezing, and in severe cases, difficulty breathing or anaphylaxis.

Understanding how your body reacts to allergens is the first step in managing these reactions effectively.

What Causes Allergic Reactions Most Commonly?

The most common causes of allergic reactions include:

• Food Allergies: Peanuts, shellfish, dairy, and eggs are frequent culprits.
• Environmental Allergens: Pollen, dust mites, pet dander, and mold.
• Medications: Antibiotics like penicillin and nonsteroidal anti-inflammatory drugs (NSAIDs).
• Contact Allergens: Substances like latex or gel nail polish can cause skin reactions (contact dermatitis).

Even seemingly minor triggers like certain fragrances or cleaning products can cause unexpected allergic responses. Recognizing these allergens can help you avoid potential reactions.

How to Treat an Allergic Reaction

Does Benadryl Help with Allergic Reactions?

Yes, Benadryl and other antihistamines are effective for treating mild allergic reactions, such as itching, runny nose, or minor swelling. They work by blocking the effects of histamine, the chemical responsible for most allergic symptoms. However, for severe reactions or anaphylaxis, antihistamines alone are insufficient. Always have access to an epinephrine injector for emergencies and seek medical care immediately.

How Do You Treat an Allergic Reaction If You’re Swelling?

If you experience swelling, especially in areas like the face, lips, or throat, act quickly. Use an antihistamine to manage minor swelling, and apply a cold compress to reduce discomfort. If swelling affects breathing or continues to worsen, visit First Priority ER immediately for professional treatment, as this may indicate a serious allergic reaction.

How Should You Treat a Peanut Allergic Reaction?

Peanut allergies are among the most severe food allergies.

If exposure occurs:

1. Administer an epinephrine injector (EpiPen) immediately.
2. Call 911 or visit the nearest ER, even if symptoms appear to subside after epinephrine.
3. Avoid lying flat; instead, stay in a seated or reclining position while waiting for emergency care.

Peanut allergies require constant vigilance, and carrying an epinephrine injector is essential.

How to Treat an Allergic Reaction to Gel Nail Polish

Allergic reactions to gel nail polish typically cause redness, itching, or swelling around the nail area.

• Remove the gel polish immediately to minimize further exposure.
• Wash the area with mild soap and water.
• Apply a topical corticosteroid cream to soothe irritation.
  For severe or persistent reactions, seek medical advice to prevent long-term skin damage.

How Long Do Allergic Reactions Last?

The duration of an allergic reaction varies based on the type and severity of the reaction:

• Mild Reactions: Typically subside within a few hours to a day with appropriate treatment.
• Moderate Reactions: May last several days if the allergen exposure is prolonged.
• Severe Reactions: Can persist until professional treatment is administered and may require hospitalization.
  Factors like the allergen type, your immune response, and the treatment method play a significant role in how long symptoms last.

Can an Allergic Reaction Cause a Fever?

While allergic reactions don’t typically cause a fever, certain severe reactions can lead to fever-like symptoms, such as a raised body temperature or chills. These are often related to systemic inflammation or a secondary infection. If you experience a fever alongside allergic reaction symptoms, consult a healthcare provider to rule out other conditions, like an infection or autoimmune response.

When to Seek Emergency Care for Allergic Reactions

Seek immediate medical attention if you experience:

• Difficulty breathing or swallowing.
• Swelling of the face, tongue, or throat.
• Severe abdominal pain, vomiting, or diarrhea after allergen exposure.
• Loss of consciousness or lightheadedness.
