Is clarithromycin good for recurrent sinus infections?

Recurrent Sinus Infe: Clarithromycin is acceptable. Unless you are allergic to penicillin, Amoxicillin is the drug choice. If you have taken antibiotics within the past six week, amoxicllin/clavulanate or Moxifloxacin are other choices. Go see your primary care provider, if your symptoms have lasted longer than seven days, as you'll need a prescription for antibiotics.
