Can sinusitis cause fever?

Sinusitis is relatively common in daily life, and some individuals believe there is a connection between fever and sinusitis. So, can sinusitis cause fever?

Can Sinusitis Cause Fever?

Sinusitis is an inflammatory condition affecting the mucosal lining of the sinuses. Common symptoms include nasal congestion, purulent nasal discharge, and headache; patients may also experience reduced or lost sense of smell. Acute sinusitis can cause fever—typically following a viral infection that triggers acute inflammation of the nasal mucosa. Patients often develop mild (low-grade) fever rather than high fever, and the body usually controls the fever within a short period.

If fever occurs secondary to acute sinusitis, it is essential to assess for potential orbital or intracranial complications. Closely monitor for signs such as periorbital swelling or pain, or severe headache. Under medical guidance, patients may be prescribed cephalosporin- or penicillin-class antibiotics—for example, cefdinir or amoxicillin. If allergic to these antibiotics, macrolide alternatives—including azithromycin, erythromycin, or roxithromycin—may be considered.

The above medications are for reference only; actual drug selection and dosing must be determined by a physician. Additionally, individuals experiencing symptoms should seek prompt medical evaluation and follow their doctor’s recommendations for appropriate management. We hope this information is helpful to you!
