A sinus infection is inflammation or mucosal thickening of the sinuses
and can be caused by bacteria, fungi, viruses or allergies. In 2/3 of people, it
is caused by a virus and thus will not respond to treatment with antibiotics. In
the event that the sinus infection is bacterial in origin, studies have shown
that antibiotic treatment, nonetheless, does not decrease the duration of
symptoms. In light of the lack of consistent evidence supporting the use of
antibiotics for bacterial sinusitis and the fact that most sinus infection are
viral in origin and will usually resolve with in 7 days, antibiotic treatment
should NOT be first line treatment in acute sinusitis.
