Red flags & when to go in person for Cough

Audience: adult

A cough is a common symptom that often results from infections, allergies, or irritants. Many coughs improve on their own or with simple care, and telemedicine can help you understand your symptoms and suggest treatments. However, some coughs may signal more serious health problems requiring in-person evaluation. Knowing the warning signs, or red flags, is important to decide when to seek urgent care. Telemedicine visits can guide you through symptom assessment and management but cannot replace physical exams or tests sometimes needed to diagnose serious conditions. This guide helps you recognize when to use telemedicine for a cough and when to get in-person care for your safety and best health outcomes.

Red flags — go in person / ER

• Difficulty breathing or shortness of breath — seek emergency care immediately.
• Coughing up blood or large amounts of mucus — get evaluated in person promptly.
• High fever persisting despite treatment or lasting more than 3 days — see a healthcare provider in person.

What telemedicine can do

• Assessment of mild to moderate cough symptoms.
• Providing guidance on symptom management and home care.
• Determining if in-person evaluation is needed.
• Monitoring symptom progression through follow-up calls.

What telemedicine cannot do

• Performing physical examinations or diagnostic tests like X-rays or lab work.
• Treating severe respiratory distress or emergencies.
• Administering treatments that require in-person procedures or equipment.
• Diagnosing complex or serious underlying conditions without in-person assessment.

Common causes of cough

Coughs often come from viral infections like the common cold or flu. Other causes include allergies, asthma, or exposure to smoke and pollution. Sometimes, coughs may be due to acid reflux or side effects of medications. Most coughs improve within a few weeks without special treatment.
