Acute Sinusitis
1 medicine
Acute sinusitis is short-term inflammation of the sinuses that usually follows a cold, causing facial pain, congestion and nasal discharge. Most cases clear on their own, though bacterial cases may need antibiotics such as moxifloxacin.
Key facts
- Acute sinusitis is inflammation of the sinuses lasting up to four weeks, most often starting after a cold or other upper respiratory infection.
- Fluid fills the sinuses, creating pressure behind the cheeks, forehead and eyes, along with congestion and nasal discharge.
- Most cases are viral and clear on their own; bacterial cases, which tend to linger or worsen after initial improvement, are treated with antibiotics such as moxifloxacin.
- Seek prompt care for a high fever, severe one-sided facial pain, swelling around the eye, a stiff neck, or symptoms that improve then suddenly worsen.
When bacteria are to blame
Most cases of acute sinusitis clear on their own as the original viral infection resolves. A smaller share are caused or complicated by bacteria, and these tend to linger longer or worsen after an initial improvement. Bacterial acute sinusitis is the situation where antibiotics become relevant. Moxifloxacin is one option used in adults when first-line treatments haven't worked or when the infection is more severe.
Supportive care
Saline nasal rinses, steam inhalation, and staying well hydrated help regardless of the cause. Moving frequently between very different indoor and outdoor temperatures can aggravate congestion for some people, so keeping indoor air circulating and dressing for the transition may ease discomfort.
When to see a doctor
Seek medical attention promptly if you develop a high fever, severe one-sided facial pain, swelling around the eye, a stiff neck, or symptoms that improve and then suddenly worsen. These can point to a complication that needs more than supportive care.
