Allergic reactions

Allergic reactions—like seasonal allergies and rashes—are common and usually manageable, especially with quick treatment. Here’s a guide to understanding symptoms, treatment, and how telemedicine can help.

1. Seasonal Allergies (Allergic Rhinitis)

Also called hay fever, this is your body’s overreaction to allergens like pollen, dust mites, mold, or pet dander.

Common Symptoms:

• Sneezing

• Runny or stuffy nose

• Itchy eyes, nose, or throat

• Watery, red eyes

• Fatigue

• Postnasal drip

• Sinus pressure or headaches

These usually occur during spring, summer, or fall, depending on the allergen (e.g., tree pollen in spring, ragweed in fall).

Treatment:

• Over-the-counter (OTC) medications:

  • Antihistamines: Cetirizine (Zyrtec), Loratadine (Claritin), Fexofenadine (Allegra)

  • Nasal sprays: Fluticasone (Flonase), Mometasone (Nasonex)

  • Decongestants: Pseudoephedrine (Sudafed) — short-term use only

• Allergy eye drops for itchy or watery eyes

• Lifestyle tips:

  • Stay indoors during high pollen times

  • Keep windows closed

  • Use air purifiers and wash bedding frequently

Telemedicine Tip: Providers can help confirm if your symptoms are allergy-related vs. a cold or sinus infection, and recommend or prescribe the right meds.

2. Skin Rashes (Allergic Dermatitis)

These are often caused by contact with an allergen or irritant—like soaps, plants (e.g., poison ivy), metals (nickel), or even food allergies.

Common Symptoms:

• Redness or inflammation

• Itching or burning sensation

• Swelling or raised bumps

• Dry, cracked, or scaly skin

• Blistering in more severe cases

Common Types:

• Contact dermatitis: Reaction from touching a substance

• Hives (urticaria): Itchy welts caused by allergic response

• Eczema flare-ups: Sometimes allergy-triggered

Treatment:

• Antihistamines for itching (Benadryl, Zyrtec, etc.)

• Topical corticosteroids (e.g., hydrocortisone cream)

• Moisturizers to soothe dry, irritated skin

• Cool compresses for comfort

Avoid scratching—it can worsen the rash or cause infection.

When to Seek Help:

• Rash is spreading or painful

• You develop a fever or swelling

• Over-the-counter treatments aren’t working

• It affects your face, eyes, or genitals

Telemedicine Tip: A provider can look at your rash via video or photo, recommend treatment, and prescribe stronger creams or antihistamines if needed.

More Serious Allergic Reactions (Anaphylaxis)

This is a medical emergency and not suitable for telemedicine.

Symptoms:

• Difficulty breathing or wheezing

• Swelling of face, lips, tongue, or throat

• Rapid heartbeat

• Dizziness or fainting

• Hives all over the body

Call 911 or go to the ER immediately. Use an EpiPen if available.

Telemedicine & Allergic Reactions

Telehealth is a great option for non-life-threatening allergic reactions, including:

• Diagnosing seasonal allergies

• Identifying and treating rashes or hives

• Managing chronic allergy symptoms

• Renewing prescriptions for allergy meds

• Allergy counseling or referrals for testing
