Sinus Infection Treatment (Acute Sinusitis)
Adult care by secure video visit, self pay option starting at $79, MD-only, insurance is not required.
Yes — adults (18+) with sinus infection symptoms can be evaluated online. A board-certified MD reviews your symptom duration by secure video and, per AAO-HNS 2025 guidance, may recommend watchful waiting for 3–5 days first, since most cases improve without antibiotics; when antibiotics are indicated, amoxicillin-clavulanate is prescribed per IDSA guidance, sent to your pharmacy same day. Visit price: $79 flat, no insurance required. Severe rapidly worsening headache with fever, or visual changes/eye swelling, needs in-person or ER evaluation.
Acute sinusitis is one of the most common reasons adults seek medical care, but most cases are viral and do not benefit from antibiotics. The AAO-HNS 2025 Adult Sinusitis Update Clinical Practice Guideline recommends watchful waiting for 3 to 5 days as the preferred initial approach for acute bacterial rhinosinusitis before considering antibiotics, because the majority of cases improve without antimicrobial therapy. The IDSA 2012 guidelines define acute bacterial rhinosinusitis (ABRS) by specific criteria: symptoms persisting 10 or more days beyond URI onset without improvement, symptoms that worsen within 10 days after initial improvement (double worsening), or severe symptoms including fever of 102°F or higher with purulent nasal discharge for 3 or more consecutive days. TeleDirectMD uses a safety-first telehealth approach that screens for red flags including severe headache with high fever, visual changes, facial swelling, and neurological symptoms before determining whether treatment by video visit is appropriate. If the history supports uncomplicated acute sinusitis without red flags, guideline-based treatment including watchful waiting or antibiotics when indicated may be reasonable by video, while adults with orbital or intracranial complications are directed to emergency care. This page is for adults located in one of our covered states, including communities nationwide.

How it works
How Online Sinus Infection Treatment Works
Book your video visit
Insurance is not required. No referral needed. Many visits are available same day, depending on scheduling. Before your visit, note when symptoms started, whether they are improving or worsening, whether you have had fever, and any prior sinus infection history or antibiotic allergies.
See a licensed MD by video
We review your symptom timeline, severity, and red flags. The IDSA defines ABRS by specific duration and severity criteria, and the AAO-HNS recommends watchful waiting as the preferred initial approach for most cases. We determine whether your presentation fits uncomplicated sinusitis appropriate for telehealth or requires in-person evaluation.
Get a treatment plan and, if appropriate, a prescription
If medication is clinically appropriate, we send an e-prescription to common pharmacies such as CVS, Walgreens, Walmart Pharmacy. Many patients benefit from supportive care alone. You receive clear follow-up steps regardless of treatment choice, including when to seek in-person care if symptoms worsen.
Treatment
Common Medication Options
These are common options for adult acute sinusitis. The actual medication, dose, and duration are determined by the MD after reviewing your symptoms, duration, severity, allergies, and red flags. Many patients with acute sinusitis improve with supportive care alone.
| Medication | Typical dose | Duration | Key considerations |
|---|---|---|---|
| Amoxicillin | 500 mg by mouth three times daily or 875 mg twice daily | 5 to 10 days | First-line antibiotic for ABRS per AAFP guidelines. Used when IDSA diagnostic criteria are met and watchful waiting has not led to improvement. |
| Amoxicillin-clavulanate | 875/125 mg by mouth twice daily | 5 to 10 days | IDSA recommends amoxicillin-clavulanate over amoxicillin alone. Preferred when broader coverage is needed or initial amoxicillin has not improved symptoms. |
| Doxycycline | 100 mg by mouth twice daily | 5 to 10 days | Alternative for penicillin allergy. Recommended by AAFP as a second-line option. Avoid in pregnancy. |
| Intranasal corticosteroid (fluticasone, mometasone) | 1 to 2 sprays per nostril daily | As directed | Supportive care to reduce mucosal inflammation and improve drainage. Can be used with or without antibiotics. |
| Nasal saline irrigation | Rinse with isotonic or hypertonic saline solution | As needed | Evidence-based supportive care that helps thin secretions and promote sinus drainage. Safe and well-tolerated. |
| Analgesics (acetaminophen or ibuprofen) | As directed on packaging | As needed for pain | For facial pain and headache management. Use appropriate dosing for age and medical history. |
| Oral or topical decongestant (pseudoephedrine, oxymetazoline) | As directed | Short-term only (topical max 3 days) | Temporary relief of nasal congestion. Topical decongestants should not be used for more than 3 days to avoid rebound congestion. |
Example regimens only. The actual medication, dosing, and duration are determined by the MD after reviewing your symptoms, risk factors, allergies, and red flags. Most acute sinusitis is viral and resolves without antibiotics. TeleDirectMD does not prescribe controlled substances.
Understanding it
What Is a Sinus Infection?
A sinus infection (sinusitis) is inflammation of the paranasal sinuses, the air-filled spaces behind the forehead, cheeks, nose, and eyes. Most acute sinusitis episodes begin as a viral upper respiratory infection and resolve without antibiotics. When bacterial infection develops, it is called acute bacterial rhinosinusitis (ABRS).
The IDSA 2012 guidelines define ABRS by three clinical scenarios: symptoms persisting 10 or more days beyond URI onset without improvement, symptoms that worsen within 10 days after initial improvement (double worsening), or severe symptoms including fever of 102°F or higher with purulent nasal discharge lasting 3 or more consecutive days.
TeleDirectMD focuses on uncomplicated acute sinusitis appropriate for telehealth, with careful screening to direct complicated cases, chronic sinusitis, and patients with red flags for orbital or intracranial complications to in-person or emergency care.
Causes & risk factors
Causes and Risk Factors
Most acute sinusitis episodes are triggered by a viral URI that causes mucosal swelling and impaired sinus drainage. Bacterial superinfection occurs in a minority of cases. Understanding the timeline and risk factors helps determine whether antibiotics are appropriate or whether watchful waiting is the safer initial approach.
- Viral upper respiratory infection: the most common trigger, typically causing symptoms that peak around days 3 to 5 and then gradually improve
- Bacterial superinfection: develops in a subset of cases when sinus drainage is impaired, typically meeting IDSA criteria of 10+ day duration, double worsening, or severe onset
- Allergic rhinitis: chronic nasal inflammation from allergies can predispose to sinus obstruction and recurrent sinusitis episodes
- Anatomic factors: deviated septum, nasal polyps, or other structural abnormalities can impair drainage and increase infection risk
- Immunosuppression: patients with weakened immune systems may develop more severe or complicated sinus infections requiring in-person evaluation
- Smoking and environmental irritants: mucosal irritation impairs ciliary clearance and increases susceptibility to sinusitis
Not every patient with nasal congestion and facial pressure has a bacterial sinus infection. The AAO-HNS emphasizes that most acute sinusitis is viral and resolves with supportive care, which is why watchful waiting is the recommended initial approach for ABRS.
Symptoms & red flags
Symptoms and Red Flags for Sinus Infection
Use this table to understand which symptoms fit uncomplicated acute sinusitis and which patterns suggest a need for urgent in-person or emergency evaluation.
| Symptom or situation | What it suggests | Telehealth appropriate? | Red flag requiring urgent in-person care |
|---|---|---|---|
| Facial pain or pressure over cheeks or forehead with nasal congestion | Acute sinusitis is possible | Often yes | If severe, rapidly worsening, or with high fever |
| Thick discolored nasal discharge for several days | May be viral or bacterial depending on timeline | Often yes | If accompanied by high fever and severe facial pain for 3+ days |
| Symptoms persisting 10+ days without improvement | Meets IDSA criteria for ABRS, antibiotics may be appropriate | Often yes | If worsening with new high fever or severe symptoms |
| Symptoms improving then worsening again (double worsening) | Meets IDSA criteria for ABRS | Often yes | If rapid worsening with new concerning features |
| Fever ≥102°F with purulent discharge for 3+ consecutive days | Meets IDSA severe onset criteria for ABRS | Sometimes | If persistent high fever with worsening despite treatment |
| Eye swelling, visual changes, or eye pain | Possible orbital complication | No | Emergency evaluation now |
| Severe headache with high fever and altered mental status | Possible intracranial complication | No | Emergency evaluation now |
| Facial cellulitis or rapidly spreading facial redness | Possible complicated sinusitis | No | Emergency evaluation now |
Not every symptom is the same
Differential Diagnosis: Sinus Infection vs Other Conditions
Several conditions can cause facial pain, nasal congestion, or headache that mimics sinusitis. TeleDirectMD evaluates symptom patterns to distinguish uncomplicated acute sinusitis from conditions requiring different treatment or in-person evaluation.
Sometimes Appropriate for Telehealth
- Acute viral rhinosinusitis with supportive care needs
- Uncomplicated ABRS meeting IDSA diagnostic criteria
- Allergic rhinitis exacerbation causing sinus-type symptoms
- Post-nasal drip and facial pressure without red flags
- Antibiotic stewardship discussion when symptoms are uncertain
Often Requires In-Person Evaluation
- Orbital complications: periorbital cellulitis, orbital abscess, or visual changes
- Intracranial complications: meningitis, brain abscess, or cavernous sinus thrombosis
- Chronic rhinosinusitis lasting 12+ weeks needing imaging and ENT referral
- Nasal polyps or suspected fungal sinusitis
- Recurrent sinusitis with 4+ episodes per year needing comprehensive workup
Viral Sinusitis vs Bacterial Sinusitis
Most acute sinusitis is viral and improves within 7 to 10 days. ABRS is diagnosed when symptoms persist 10+ days without improvement, worsen after initial improvement (double worsening), or present with severe onset (fever ≥102°F with purulent discharge for 3+ days). This distinction matters because antibiotics only help bacterial cases.
Sinusitis vs Migraine or Tension Headache
Facial pressure and headache can occur with sinusitis but also with migraine, tension headache, and dental causes. True sinusitis typically includes nasal congestion with thick discolored discharge, while migraine often involves light sensitivity, nausea, or visual aura without nasal symptoms.
If your symptoms do not match uncomplicated acute sinusitis or any red flags are present, TeleDirectMD will direct you to urgent in-person care or the ER.
Treatment approach
Treatment Options
The AAO-HNS 2025 guideline recommends watchful waiting for 3 to 5 days as the preferred initial approach for ABRS, because most cases improve without antibiotics. When antibiotics are indicated, the AAFP and IDSA recommend amoxicillin with or without clavulanate as first-line therapy. The IDSA specifically recommends amoxicillin-clavulanate rather than amoxicillin alone.
Supportive care and watchful waiting
For most patients with acute sinusitis, supportive care is the appropriate first step. Nasal saline irrigation helps thin secretions and promote drainage. Intranasal corticosteroids such as fluticasone or mometasone can reduce mucosal inflammation. Analgesics manage pain. Oral decongestants or short-term topical decongestants (no more than 3 days) may provide temporary relief.
Antibiotics when indicated
If symptoms meet IDSA criteria for ABRS and do not improve with watchful waiting, or if severe onset criteria are met, first-line antibiotic therapy is amoxicillin 500mg three times daily or 875mg twice daily for 5 to 10 days, or amoxicillin-clavulanate 875/125mg twice daily for 5 to 10 days. For penicillin allergy, doxycycline 100mg twice daily for 5 to 10 days is an alternative.
When telehealth care is not enough
If symptoms worsen despite appropriate antibiotic therapy, if red flags develop at any point, or if the pattern suggests chronic rhinosinusitis, nasal polyps, or complicated infection, in-person evaluation with possible imaging or ENT referral is needed.

Common questions
Sinus Infection Treatment FAQs
Can I get treatment for a sinus infection online?
Yes, if you are an adult 18+ located in one of our covered states and your symptoms fit uncomplicated acute sinusitis without red flags. TeleDirectMD can evaluate your symptoms, determine whether watchful waiting or antibiotics are appropriate based on clinical guidelines, and prescribe medication when clinically indicated.
How much does online sinus infection treatment cost?
TeleDirectMD offers a transparent self pay option starting at $79 for an adult video visit. Insurance is not required. Prescription costs at your pharmacy are separate and vary by medication and pharmacy.
Do I need antibiotics for a sinus infection?
Not always. Most acute sinusitis is viral and improves without antibiotics. The AAO-HNS 2025 guideline recommends watchful waiting for 3 to 5 days as the preferred initial approach for acute bacterial rhinosinusitis. Antibiotics are appropriate when symptoms persist 10 or more days without improvement, worsen after initial improvement, or present with severe onset such as fever of 102°F or higher with purulent nasal discharge for 3 or more consecutive days.
What antibiotics are used for sinus infections?
When antibiotics are indicated, amoxicillin with or without clavulanate is the recommended first-line therapy per AAFP and IDSA guidelines. The IDSA specifically recommends amoxicillin-clavulanate over amoxicillin alone. For penicillin allergy, doxycycline is an alternative. The actual choice depends on your allergies, medical history, and severity.
How do I know if my sinus infection is bacterial or viral?
The IDSA defines acute bacterial rhinosinusitis by three criteria: symptoms persisting 10 or more days without improvement, symptoms that worsen within 10 days after initial improvement (double worsening), or severe symptoms including fever of 102°F or higher with purulent nasal discharge for 3 or more consecutive days. If your symptoms are improving within 7 to 10 days, the cause is likely viral.
When should I go to the ER for a sinus infection?
Seek emergency care for severe headache with high fever, visual changes or eye swelling or eye pain, altered mental status or confusion, neck stiffness, facial cellulitis or rapidly spreading facial swelling, or any signs suggesting orbital or intracranial complication. These are rare but serious complications that require immediate evaluation.
Can nasal saline irrigation help with sinusitis?
Yes. Nasal saline irrigation is an evidence-based supportive treatment that helps thin secretions, promote sinus drainage, and reduce symptoms. It can be used for both viral and bacterial sinusitis and is recommended as part of standard supportive care.
Does your state allow telemedicine for sinus infection treatment?
Yes. Your state allows licensed professionals to provide telemedicine within their scope when appropriate and according to accepted standards of care. You must be physically located in one of our covered states at the time of the visit.
What if my sinus infection does not improve after antibiotics?
If symptoms are not improving within 48 to 72 hours of starting antibiotics, you should be reassessed. You may need a different antibiotic, an alternative diagnosis considered, or in-person evaluation with possible imaging. If red-flag symptoms develop at any point, seek emergency care immediately.
Can TeleDirectMD treat chronic sinusitis?
No. TeleDirectMD focuses on uncomplicated acute sinusitis. Chronic rhinosinusitis, defined as symptoms lasting 12 or more weeks, typically requires in-person evaluation with imaging and often ENT referral. If your symptoms have been ongoing for many weeks, we will direct you to the appropriate level of in-person care.
Do I need antibiotics for a sinus infection, or will telehealth just tell me to wait it out?
Often the latter — most acute sinus infections are viral and improve within 3 to 5 days without antibiotics, so the MD may recommend supportive care like nasal saline and decongestants first. Antibiotics are reserved for cases meeting specific bacterial criteria or that aren't improving.
How much does online sinus infection treatment cost without insurance?
The visit is $79 flat, no insurance required, and generic amoxicillin-clavulanate, if prescribed, typically adds $10 to $25 at the pharmacy — most patients pay under $105 total.
