A sinus infection can leave you with facial pressure, congestion, and a headache that drags on for days, and seeing an online doctor is often the fastest way to get evaluated and treated. A licensed clinician can review your symptoms remotely and, if antibiotics are warranted, send a prescription to your pharmacy. This guide explains how to see an online doctor for a sinus infection, when antibiotics are appropriate, what it costs, and when you need in-person care.

Can an online doctor treat a sinus infection?

Yes. Sinus infections are among the most commonly treated conditions in telehealth. An online clinician will ask about your symptoms, how long they have lasted, and your history, and then recommend a treatment plan, which may include symptom relief, a nasal spray, or antibiotics if a bacterial infection is suspected. The key thing to understand is that most sinus infections are viral and do not need antibiotics, so a good online doctor will not simply hand them out.

When do you actually need antibiotics?

This matters, because antibiotics only help bacterial sinus infections, and the vast majority of sinus infections are viral. A clinician typically considers antibiotics when your symptoms point to a bacterial cause, generally: symptoms lasting more than 10 days without improvement, symptoms that worsen after initially getting better ("double worsening"), or severe symptoms like high fever with thick nasal discharge and facial pain. If you are in the first several days of a cold-like illness, antibiotics usually will not help and can cause side effects, so an online doctor may recommend symptom relief and watchful waiting instead.

How an online sinus visit works

The process is quick. You describe your symptoms and their duration, sometimes through a questionnaire and sometimes a video visit, a US-licensed clinician evaluates whether your infection is likely viral or bacterial, and they send any prescription to your pharmacy. For services like August, this happens within hours. If antibiotics are appropriate, amoxicillin or amoxicillin-clavulanate is a common first choice. The clinician should also tell you when to seek in-person care.

Your insurance or primary care

If you have insurance, a covered telehealth visit may cost little, and your own clinician knows your history.

How much does it cost?

The visit and any medication are billed separately. Visits run about $34 to $99 cash, or a flat $39 at August, and $0 to a low copay with insurance. If antibiotics are prescribed, they are inexpensive generics, often around $10 to $15 with a discount card. So the visit is usually the main cost.

When to seek in-person or emergency care

See someone in person or go to the ER if you have a high fever that won't break, severe or worsening facial swelling or redness, swelling around the eyes or vision changes, a severe headache with a stiff neck, or confusion. These can signal a complication that needs hands-on evaluation. Online care is appropriate for typical, uncomplicated sinus symptoms, not for these warning signs.

Frequently Asked Questions

Yes, if the clinician determines your infection is likely bacterial. Because most sinus infections are viral, antibiotics are not always appropriate, and a responsible online doctor will recommend them only when your symptoms fit a bacterial pattern, such as lasting more than 10 days or worsening after improvement. Otherwise they will suggest symptom relief.

Most viral sinus infections improve within about 10 days. Consider seeing a doctor if symptoms last longer than 10 days without improving, worsen after initially getting better, or are severe with high fever and facial pain. These patterns suggest a possible bacterial infection that may benefit from antibiotics, which a clinician can assess.

Cash visits run about $34 to $99, or a flat $39 at August, and $0 to a low copay with insurance. If antibiotics are prescribed, they are cheap generics, often $10 to $15 with a discount card. The visit is usually the main cost, and many services charge nothing if they can't treat you online.

Most are viral, often following a cold, and improve on their own within about 10 days. A smaller share are bacterial, suggested by symptoms lasting more than 10 days, double worsening, or severe fever and facial pain. Only bacterial sinus infections benefit from antibiotics, which is why a clinician evaluates the likely cause first.

Yes, and usually it should be. Most sinus infections are viral and resolve with symptom relief like rest, fluids, saline rinses, decongestants, and pain relievers. Antibiotics help only bacterial infections and can cause side effects when used unnecessarily, so clinicians reserve them for cases that fit a bacterial pattern.
