what medication do doctors give for sinus infections
People with sinusitis due to the common cold or other causes are often prescribed antibiotics.

Sinusitis usually stems from a viral infection, not a bacterial oneâand antibiotics donât work against viruses. Even when bacteria are responsible, infections usually clear up on their own within a week.
