What Is Sinusitis and Why Might It Require Antibiotics?

Sinusitis is an inflammation of the air cavities (sinuses) inside the face.

In most cases, it’s viral and resolves without antibiotics.

However, when symptoms persist for more than ten days or worsen after temporary improvement, this could indicate a bacterial infection that requires proper antibiotic therapy.

According to the Saudi Ministry of Health and the Saudi Food and Drug Authority (SFDA), antibiotics must only be prescribed under medical supervision to avoid bacterial resistance and ensure patient safety.

When Does a Sinus Infection Need Antibiotic Treatment?

Not every sinus infection requires antibiotics.

For viral sinusitis, rest, hydration, and saline sprays are usually enough.

Antibiotics are only prescribed when there are signs of a bacterial infection, such as:

• Symptoms lasting more than 10 days without improvement.
• High fever above 38.5°C.
• Thick yellow or green nasal discharge.
• Severe facial pain or pressure around the eyes.

The Best Antibiotic for Sinus Infection (Depending on the Case)

1. Acute Sinusitis

Amoxicillin–Clavulanate (Augmentin) is considered the first-line antibiotic for most bacterial sinus infections.
For patients allergic to penicillin, alternatives include:

• Doxycycline
• Cefuroxime

Treatment usually lasts 7–10 days, depending on symptom severity and patient response.

2. Chronic Sinusitis

When the infection lasts longer than 12 weeks, broad-spectrum antibiotics may be required, such as:

• Levofloxacin
• Ciprofloxacin

Long-term cases require close follow-up with the ENT specialist to monitor progress and prevent antibiotic resistance.

3. Allergic or Fungal Sinusitis

In these cases, antibiotics are not used because the cause isn’t bacterial.
Treatment instead includes:

• Anti-inflammatory medications.
• Antifungal drugs if a fungal infection is confirmed.
• Corticosteroid nasal sprays to reduce swelling and congestion.

Doctors’ Tips for Safe and Effective Antibiotic Use

As recommended by the Saudi Ministry of Health:

• Always complete the full antibiotic course even if you feel better.
• Never self-medicate or take leftover antibiotics.
• Drink plenty of fluids to help clear mucus.
• Avoid smoking, which worsens sinus inflammation.
• Contact your doctor if symptoms don’t improve after three days of antibiotic use.

Natural Remedies to Support Antibiotic Treatment

Alongside medical therapy, several home remedies can help ease sinus symptoms and complement your sinus infection treatment plan:

• Steam inhalation two to three times daily.
• Saline nasal rinses to clear mucus.
• Sleeping with your head elevated to improve drainage.
• Drinking warm fluids and herbal teas to stay hydrated.

These remedies support healing but don’t replace medical treatment.

When Should You See a Doctor Immediately?

Seek immediate medical help from your ENT specialist if you experience:

• Persistent high fever despite treatment.
• Severe pain around the eyes or forehead.
• Facial swelling or eye puffiness.
• Difficulty breathing or double vision.
