Sinus infections are miserable, but most don't actually need antibiotics. A quick virtual visit can tell you whether you're dealing with a lingering virus that needs supportive care or a bacterial infection that calls for a prescription, so you can stop guessing and start feeling better.
Sinus infection symptoms
Sinusitis tends to cause a cluster of familiar symptoms:
- Facial pressure or pain around the eyes, cheeks, and forehead
- Thick yellow or green nasal discharge
- Nasal congestion or blockage
- A reduced sense of smell
- A pressure-type headache
- Low-grade fever
- Fatigue and a general run-down feeling
- Aching in the upper teeth when the maxillary sinuses are involved
Viral versus bacterial sinusitis
Here's the part most people don't hear: over 90% of acute sinus infections are viral and won't respond to antibiotics at all. A bacterial infection becomes more likely when:
- Symptoms persist beyond 10 days without improving
- Symptoms improve and then suddenly worsen (the "double sickening" pattern)
- Symptoms are severe from the start, with high fever and significant facial pain
As Dr. Erik Petersen puts it, "A 15-minute visit can tell you exactly what you need." That's the whole point of an evaluation before you reach for antibiotics.
Treatment options
When we evaluate you, we match the treatment to the cause. Depending on what we find, and when medically appropriate, options may include:
- Antibiotics such as amoxicillin-clavulanate for confirmed bacterial cases, or doxycycline for a penicillin allergy
- Nasal steroid sprays like fluticasone or mometasone to reduce inflammation
- Decongestants such as pseudoephedrine for congestion relief
- Saline irrigation, an evidence-based way to ease symptoms
- Mucolytics like guaifenesin to thin mucus
We prescribe non-controlled medications only. When a prescription makes sense, we send it electronically, and our prescription price finder can show you the cash price at a pharmacy nearby.
What to expect from treatment
Recovery timelines are reassuringly predictable:
- Bacterial sinusitis treated with antibiotics usually improves within 3 to 5 days and resolves in 10 to 14 days
- Viral sinusitis typically resolves in 10 to 14 days with supportive care alone
Sinus infection versus a common cold
A cold usually clears within 7 to 10 days. A sinus infection tends to last longer, brings more facial pressure and pain, produces thicker discolored mucus, and may come with a fever. If your "cold" is dragging past the 10-day mark or got worse after seeming to improve, it's worth a look. Curious how a visit works? See our how it works page.
Simple steps that speed recovery
Whether your infection turns out to be viral or bacterial, a few habits genuinely help you feel better faster. Rinsing with saline once or twice a day flushes out mucus and irritants and is one of the most evidence-backed things you can do at home. Staying well hydrated thins secretions so they drain more easily, and warm compresses over the cheeks and forehead can ease pressure. Sleeping with your head slightly elevated reduces overnight congestion, and running a humidifier keeps your nasal passages from drying out. Give these a real try before assuming you need a prescription, since most sinus infections improve on their own with good supportive care.
When to seek emergency or in-person care
Most sinus infections are safe to manage from home, but a few symptoms mean you should be seen in person or head to the ER without delay.
- High fever (103°F or above) that doesn't respond to treatment
- Swelling, redness, or pain around one eye, or vision changes
- Severe headache with a stiff neck or confusion
- Difficulty breathing or severe shortness of breath
- Signs of a severe allergic reaction, or rapidly worsening symptoms
If in doubt, call 911 or go to your nearest ER. Virtual care is best for non-emergency situations.
FAQ
Do sinus infections always need antibiotics? No. Most sinus infections are viral and resolve within about 10 days without antibiotics. We only recommend antibiotics when your symptoms point to a bacterial cause.
What's the difference between a sinus infection and a cold? Sinus infections usually last longer than 10 days, cause facial pressure and pain, produce thick discolored mucus, and may involve fever. Colds typically resolve within 7 to 10 days.
Can I get a sinus infection prescription online? Yes, when your symptoms suggest bacterial sinusitis, such as lasting more than 10 days, severe facial pain, high fever, or a worsening pattern. We prescribe non-controlled medications only when medically appropriate.
What's the best OTC treatment for sinus pressure? Saline nasal irrigation, pseudoephedrine, guaifenesin, and nasal steroid sprays can all help relieve pressure and congestion while your body recovers.
