Do most cases of sinusitis resolve without the use of antibiotics?

Most cases of sinusitis resolve without the use of antibiotics because the condition is often caused by viral infections, which cannot be treated with antibiotics. In fact, many episodes of acute sinusitis improve on their own within a week or two as the body’s immune system effectively clears the viral infection.

Additionally, even when sinusitis is caused by a bacterial infection, the symptoms often resolve spontaneously without antibiotic treatment, especially in mild or moderate cases. Overprescribing antibiotics for sinusitis can contribute to antibiotic resistance and is generally discouraged unless the patient displays severe symptoms or has other risk factors for complications.

Therefore, recognizing that the majority of sinusitis cases are self-limiting reinforces the idea that a watchful waiting approach can often be the best first line of action.
