Can Telemedicine Treat Drug Rash (Exanthem) - Triage?

Audience: pediatric

A drug rash, also called an exanthem, is a skin reaction that can happen when a child takes certain medicines. It usually appears as red spots or bumps and may be itchy. Many drug rashes are mild and can be safely checked through telemedicine. During a video or phone visit, a healthcare provider can ask about symptoms, look at the rash, and help decide the best care. However, some drug rashes can be serious and need urgent in-person care. Telemedicine can help guide families on when to seek emergency help or visit a clinic. This guide explains what telemedicine can and cannot do for drug rashes in children, how to prepare for a virtual visit, and important warning signs to watch for.

Red flags — go in person / ER

• Swelling of the face, lips, tongue, or throat causing difficulty breathing — seek emergency care immediately.
• High fever (above 38.5°C or 101.3°F) with rash and child appears very unwell — go to emergency services.
• Skin blistering, peeling, or open sores — urgent in-person evaluation needed.

What telemedicine can do

• Assessment of mild to moderate drug rashes via visual inspection and symptom review.
• Providing guidance on medication use and symptom management.
• Triage to determine if in-person care is needed.
• Education on warning signs and when to seek emergency care.

What telemedicine cannot do

• Emergency situations involving breathing difficulty or severe allergic reactions.
• Severe rashes with blistering, peeling, or extensive skin damage.
• Need for physical examination beyond visual inspection.
• Administration of treatments requiring in-person procedures or monitoring.

What Is a Drug Rash (Exanthem)?

A drug rash is a skin reaction caused by a medicine. It often looks like red spots or bumps that can spread over the body. The rash may be itchy or uncomfortable. Drug rashes usually start within days of taking a new medicine but can appear later. They are different from rashes caused by infections or allergies to foods or other things.

How Telemedicine Can Help

Telemedicine allows a healthcare provider to see and talk with you about your child's rash using video or phone. They can ask about the medicine your child took, the rash's appearance, and other symptoms. This helps decide if the rash is mild and can be watched at home or if your child needs to see a doctor in person. Telemedicine can provide advice on how to care for the rash and when to get emergency help.

When to Seek In-Person Care

Some drug rashes can be serious and need urgent medical attention. Signs include swelling of the face or mouth, difficulty breathing, high fever, blistering or peeling skin, or if your child looks very unwell. If these happen, go to an emergency room or call emergency services immediately. Telemedicine is not a substitute for emergency care in these situations.

Preparing for a Telemedicine Visit

Before the visit, have the following ready:

This helps the provider make the best assessment.

After the Telemedicine Visit

Follow the healthcare provider's advice carefully. This may include stopping the suspected medicine, using creams or antihistamines, and watching for changes. If symptoms worsen or new warning signs appear, seek in-person care promptly. Keep track of any new symptoms and follow up as recommended.

How to prepare for your tele-visit

• Take clear photos or videos of the rash in good lighting.
• List all current medicines your child is taking, including recent changes.
• Note when the rash first appeared and any other symptoms.
• Find a quiet place with reliable internet or phone connection for the visit.
• Have a caregiver available to assist during the telemedicine appointment if needed.

After your tele-visit

• Follow the healthcare provider’s instructions about stopping or continuing medicines.
• Use recommended treatments such as creams or antihistamines as advised.
• Monitor your child’s symptoms closely for any worsening or new signs.
• Seek in-person care if red flags or emergency symptoms develop.
• Schedule follow-up appointments if recommended by the provider.

FAQs

Can telemedicine diagnose a drug rash in my child?

Telemedicine can help healthcare providers assess the rash based on images and symptoms you describe. While it can often identify a drug rash, it is not a substitute for a full in-person exam if the rash is severe or unclear.

What should I do if my child has a rash and a fever?

If your child has a rash with a high fever or looks very sick, seek in-person medical care promptly. Telemedicine can help triage, but fever with rash can sometimes signal serious illness.

Can I continue giving my child their medicine if they have a rash?

Do not stop or change any medicine without first consulting a healthcare provider. Some rashes require stopping the medicine, but this should be done under medical advice.

How can I help my child feel more comfortable with a drug rash?

You can use cool compresses, keep the skin clean, and use over-the-counter anti-itch creams if recommended. Avoid scratching to prevent infection.

When should I call emergency services for a drug rash?

Call emergency services if your child has swelling of the face or throat, difficulty breathing, severe blistering or peeling skin, or is very difficult to wake or unusually sleepy.
