Tele-triage for Hives

Audience: adult

Hives are raised, itchy, red or skin-colored welts that often appear suddenly and can vary in size. They may result from allergic reactions, infections, stress, or other triggers. Telemedicine can be a helpful way to assess hives, especially when symptoms are mild or moderate. Through a virtual visit, a healthcare provider can review your symptoms, ask about possible triggers, and suggest treatments to relieve itching and swelling. However, some situations require urgent in-person care, such as difficulty breathing or swelling of the face and throat. This guide explains when tele-triage for hives is appropriate, what to prepare for your tele-visit, warning signs to watch for, and typical next steps after your consultation. Remember, telemedicine is a tool to help you get timely advice but does not replace emergency care or a thorough in-person evaluation when needed.

What Are Hives?

Hives, also known as urticaria, are raised, red or skin-colored bumps or welts that can itch or burn. They may appear anywhere on the body and often change shape or location quickly. Hives happen when the body releases histamine and other chemicals in response to triggers like allergies, infections, or stress.

When to Use Telemedicine for Hives

Telemedicine can help you get advice about hives when symptoms are mild or moderate. A healthcare provider can ask about your rash, recent exposures, medications, and other health conditions. They may suggest treatments such as antihistamines or skin care tips. Tele-triage is useful if you cannot visit a clinic easily or want quick guidance on managing symptoms.

FAQs

Can telemedicine diagnose the cause of my hives?

What treatments can I get through a telemedicine visit?

You may receive advice on over-the-counter antihistamines, skin care, and avoiding triggers. Prescription medications may also be recommended if appropriate.

When should I go to the emergency room for hives?

Go to the emergency room if you have trouble breathing, swelling of the face or throat, dizziness, fainting, or a rapid heartbeat. These could be signs of a severe allergic reaction.
