When you need in-person care instead

If your symptoms are severe, rapidly worsening, or accompanied by any of the signs below, a written visit is not the right route. Seek in-person care or call 911.

High fever with shaking chills

Severe or worsening pain

Vomiting that prevents you keeping fluids down

Confusion, fainting, or feeling very unwell

Trouble breathing or chest pain

Symptoms that have not improved on prior treatment

If you start a visit and we conclude you need in-person care, we tell you and refund you in full.
