How to prepare for a video visit about Drug Rash (Exanthem) - Triage

Audience: adult

A drug rash, also called an exanthem, is a skin reaction that can happen after taking certain medicines. It usually appears as red spots or bumps on the skin and may be itchy or uncomfortable. Many drug rashes are mild and go away once the medicine is stopped. However, some rashes can be serious and need prompt medical attention. Preparing well for your video visit can help your healthcare provider understand your symptoms better and decide the best care for you. This guide explains what to expect during your telemedicine visit, how to get ready, and when to seek urgent care. Remember, telemedicine is a helpful way to discuss your symptoms but is not a replacement for in-person medical evaluation if your condition worsens or you have serious symptoms.

Red flags — go in person / ER

• Difficulty breathing, swallowing, or swelling of face, lips, tongue, or throat — seek emergency care immediately.
• High fever (above 38°C or 100.4°F) with rash and feeling very unwell — contact emergency services.
• Rash with blistering, peeling, or open sores — get urgent medical evaluation.

What telemedicine can do

• Initial assessment of rash appearance and symptoms via video.
• Review of medication history to identify possible causes.
• Providing advice on skin care and symptom management.
• Guidance on when to seek in-person or emergency care.

What telemedicine cannot do

• Performing physical skin tests or biopsies.
• Administering emergency treatments such as injections or intravenous medications.
• Diagnosing severe or life-threatening reactions without in-person evaluation.
• Providing prescriptions that require physical examination or urgent intervention.

What is a Drug Rash (Exanthem)?

A drug rash is a skin reaction caused by a medicine. It often looks like red spots, bumps, or patches on the skin. The rash may spread over large areas and can be itchy or uncomfortable. Drug rashes usually start within days to weeks after starting a new medicine. They are different from rashes caused by infections or allergies to foods or other things.

How Telemedicine Can Help

During a video visit, your healthcare provider can see your rash and ask questions about your symptoms, medicines, and health history. This helps them decide if your rash might be from a drug and whether you need to stop the medicine or get more tests. They can also guide you on how to care for your skin and when to get urgent help.

FAQs

What causes a drug rash?

A drug rash happens when your body's immune system reacts to a medicine. This reaction can cause redness, bumps, or itching on your skin. Not everyone reacts the same way, and some medicines are more likely to cause rashes than others.

Can a drug rash go away on its own?

Often, mild drug rashes improve once the medicine causing it is stopped. However, it may take days or weeks for the rash to fully clear. Always check with your healthcare provider before stopping any medicine.

Is a drug rash contagious?

No, drug rashes are not contagious. You cannot catch a drug rash from someone else. It is a reaction inside your own body to a medicine.

What should I do if my rash gets worse after the video visit?

If your rash spreads quickly, blisters, or you develop symptoms like difficulty breathing, swelling, or high fever, seek emergency medical care immediately. Do not wait for another video visit.

Can telemedicine diagnose my drug rash accurately?

Telemedicine allows your provider to see your rash and ask questions, which helps in making a good initial assessment. However, some cases may need in-person exams or tests for a full diagnosis.
