Sinus infections are a common reason adults seek medical care, especially during cold and allergy seasons. While many sinus infections get better on their own, some may require antibiotics or further evaluation.
What Is a Sinus Infection?
A sinus infection, also called sinusitis, occurs when the tissues lining the sinuses become inflamed. This can lead to congestion, facial pressure, and difficulty breathing through the nose. The sinuses are air-filled spaces located behind the forehead, cheeks, and eyes. When these spaces become swollen or blocked, mucus can build up and cause symptoms. Sinus infections can be caused by viruses, bacteria, allergies, or other conditions that affect the nasal passages.
What Are the Symptoms of a Sinus Infection?
Common symptoms include nasal congestion, facial pressure, and thick nasal drainage. Symptoms may vary depending on the cause and severity of the infection.
Common signs of sinusitis include:
- Stuffy or blocked nose
- Thick yellow or green nasal mucus
- Facial pain or pressure
- Headache
- Postnasal drip
- Cough, especially at night
- Reduced sense of smell
- Bad breath
A sinus infection often develops after a cold or upper respiratory infection.
What Causes a Sinus Infection?
Most sinus infections are caused by viruses, the same germs responsible for the common cold. Bacterial infections are less common but can occur. Because most sinus infections are viral, antibiotics are not always necessary.
When Do You Need Antibiotics?
Antibiotics are generally recommended only when a bacterial sinus infection is suspected. Most viral sinus infections improve without antibiotic treatment.
A healthcare provider may consider antibiotics if:
- Symptoms last longer than 10 days without improvement
- Symptoms improve but then worsen again
- Fever, facial pain, and nasal discharge are severe
- Symptoms are significantly aƯecting daily activities
Using antibiotics only when appropriate helps prevent antibiotic resistance andunnecessary side effects.
How Are Sinus Infections Treated?
Treatment depends on the cause of the infection and the severity of symptoms. Many cases can be managed with supportive care.
Common treatment options include:
- Rest
- Drinking plenty of fluids
- Saline nasal sprays or rinses
- Humidified air
- Over-the-counter pain relievers when appropriate
- Prescription medications if recommended by your provider
Most viral sinus infections begin improving within one to two weeks. Seek prompt medical care if you develop severe face or eye pain, vision changes, significant swelling around the eyes, or any other severe symptoms.
Frequently Asked Questions

Yellow or green mucus can occur with both viral and bacterial infections and does not automatically mean antibiotics are needed.
3. Can allergies cause sinus infections?
Yes. Allergies can cause inflammation and blockage that increase the risk of sinus infections.
4. Are sinus infections contagious?
The infection itself may not be contagious, but the viruses that often cause sinus infections can spread from person to person.
