Virtual ER · 24/7 Emergency Telemedicine & Virtual Urgent Care

24/7 Online COVID-19 Evaluation & Oral Antiviral Prescriptions.

A positive test can bring up practical questions: what care might help, whether treatment is appropriate and what to watch for. A video visit lets you work through those questions with a clinician.

What to tell us about your symptoms

COVID-19 may cause cough, fever, fatigue, sore throat or other symptoms. A test and the timing of symptoms can help inform the evaluation.

What the video visit can help with

Tell us the first day you felt ill, when you tested and whether you have conditions that raise your risk of severe illness. Our physicians and nurse practitioners can review treatment questions and the need for a different level of care.

When an examination or testing may be needed

Bring any test results you already have. A clinician may discuss additional testing or an examination when the information is unclear or symptoms are concerning.

Discussing treatment

Some higher-risk people may benefit from antiviral treatment started early in the illness. Eligibility, medicine interactions and the clinical history matter. A video visit does not mean a particular antiviral will be prescribed.

When to get care in person

Get emergency help for trouble breathing, persistent chest pain or pressure, new confusion or difficulty staying awake. Do not wait for an online treatment discussion when symptoms are severe.

Before your visit

Have a current medicine list, including supplements, and the dates of symptoms and test results. Mention kidney or liver problems and any treatment already started.

Can I ask about COVID-19 medication online?

Yes. The visit can address eligibility and medicine interactions. Treatment choices depend on your situation and current guidance, not a positive test alone.
