What to tell us about your symptoms

Sneezing, a runny nose and itchy or watery eyes can occur with allergies. Symptoms can overlap with a cold or sinus problem.

What the video visit can help with

Talk through where and when symptoms show up, whether they recur and how much they affect sleep or daily activities. Mention asthma, other health conditions and every medicine you already take.

When an examination or testing may be needed

A video visit is a conversation and assessment, not an allergy-testing appointment. Testing or a specialist evaluation may be useful when the cause is unclear or symptoms are difficult to control.

Discussing treatment

Our physicians and nurse practitioners can discuss symptom-management options and whether prescription treatment is appropriate. Bring up side effects or medicines that have not worked well for you rather than adding another product on your own.

When to get care in person

Throat or tongue swelling, trouble breathing, fainting or a rapidly worsening reaction needs emergency care. Call 911 for a suspected severe allergic reaction.

Before your visit

Have your current allergy medicines available so you can read their names and strengths. Mention a new exposure or product without assuming it has already been proven to be the cause.
