Sinusitis Treatment Online

What is sinusitis?

Sinusitis is an inflammation of the sinuses, the air-filled cavities in the bones around the nose and eyes. It commonly occurs following a cold or upper respiratory infection, when the sinus linings become swollen and block normal mucus drainage. Sinusitis affects millions of Australians each year and can be acute (lasting less than 4 weeks) or chronic (lasting more than 12 weeks).

Symptoms typically include facial pain or pressure (particularly around the forehead, cheeks, or eyes), nasal congestion, thick discoloured nasal discharge, reduced sense of smell, headache, and sometimes fever. The condition can range from mild discomfort to significant pain that affects daily activities.

When to see a doctor about sinusitis

You should see a GP if your sinus symptoms have lasted more than 10 days without improvement, if you have severe symptoms such as high fever or intense facial pain, if your symptoms initially improved then worsened (which may suggest a secondary bacterial infection), or if you experience recurrent episodes of sinusitis.

Seek urgent medical attention if you develop swelling around the eyes, severe headache, high fever, confusion, or visual changes, as these may indicate a rare but serious complication. Your GP can also arrange an ENT specialist referral for chronic or complicated sinusitis.

How a telehealth GP can help with sinusitis

A telehealth GP can assess your sinusitis symptoms and recommend appropriate treatment without requiring an in-person visit. Your GP can determine whether your sinusitis is likely viral (which typically resolves without antibiotics) or bacterial (which may require prescription medication), based on your symptom duration and severity.

During your consultation, your GP can prescribe medication if clinically indicated, provide advice on symptom management, arrange imaging such as a CT scan if needed, issue a medical certificate if you need time off, and refer you to an ENT specialist for chronic or recurrent cases.

Acute vs chronic sinusitis

Not all sinus infections are the same, and understanding the type of sinusitis you may have can help guide the right treatment approach. Acute sinusitis typically lasts less than four weeks and usually follows a cold or upper respiratory infection. Most cases resolve on their own with supportive care. Subacute sinusitis refers to symptoms that persist for four to twelve weeks and may require closer monitoring by your GP.

Chronic sinusitis is defined as sinus inflammation lasting longer than 12 weeks, even with treatment attempts. It may involve nasal polyps, ongoing congestion, and a reduced sense of smell. Contributing factors can include allergies, structural abnormalities, or recurrent infections. Recurrent sinusitis, typically defined as four or more episodes per year with symptom-free intervals between them, may also warrant further investigation.

When you see an online GP in Australia through bulk billed telehealth, they can help determine which type of sinusitis you may be experiencing and recommend an appropriate management plan. For chronic or recurrent cases, your GP may suggest an ENT referral or imaging to investigate further.

Sinusitis medications: Nasonex, Avamys, antibiotics

Most acute sinusitis is caused by viruses and resolves within two to three weeks without antibiotics. Your GP may recommend supportive measures such as saline nasal irrigation, steam inhalation, hydration, and over-the-counter pain relief during this time.

For symptoms that persist or recur, Australian Therapeutic Guidelines recommend intranasal corticosteroid sprays as first-line treatment, which reduce inflammation and improve sinus drainage. Common options on the PBS or available over-the-counter include:

• Mometasone furoate (Nasonex) — once-daily intranasal spray. Available in generic form.
• Fluticasone furoate (Avamys) — once-daily intranasal spray with low systemic absorption.
• Budesonide (Rhinocort) — twice-daily intranasal spray.

Antibiotics are reserved for cases where bacterial sinusitis is clinically likely — typically symptoms lasting more than 10 days, severe pain or fever, or a double-worsening pattern. First-line per Therapeutic Guidelines is amoxicillin 500 mg three times daily for 5–7 days, with amoxicillin-clavulanate (Augmentin) reserved for treatment-resistant or severe cases. Doxycycline or trimethoprim-sulfamethoxazole (Bactrim) are alternatives for penicillin-allergic patients.

For chronic sinusitis (over 12 weeks), longer-term intranasal corticosteroids, regular saline rinses, and investigation of underlying factors such as allergies or structural abnormalities are the mainstay. Referral to an ENT specialist is appropriate for cases that do not respond to medical management, where nasal polyps are suspected, or if surgery is being considered.

Home remedies and prevention

Alongside any treatment your GP recommends, there are several measures that may help relieve sinus infection symptoms and support recovery at home. Saline nasal irrigation, using a neti pot or squeeze bottle with a sterile saline solution, can help flush mucus and reduce congestion. Steam inhalation, such as breathing over a bowl of warm water with a towel draped over your head, may also provide temporary relief from blocked sinuses.

Staying well hydrated helps thin mucus, making it easier to drain. Using a humidifier in dry environments may also help keep your nasal passages moist and comfortable. If you know that certain allergens trigger your symptoms, avoiding these where possible can help reduce the frequency of sinusitis episodes. Good hand hygiene, regular handwashing and avoiding touching your face, can reduce your risk of catching the colds that often precede sinus infections.

If you experience hay fever or allergic rhinitis, managing your allergies with the help of your GP may reduce your likelihood of developing sinusitis. Your online GP can discuss allergy management strategies and whether sinusitis treatment online through bulk billed telehealth is appropriate for your situation, or if an in-person review with a Medicare-covered consultation would be more suitable.
