LaurasJourney 23 Posted February 14, 2013 I had rny 6 months ago. I'm now sick with a sinus infection. My general practitioner doesn't know much about gastric bypass. Can I just take a zpack? I'm allergic to amoxicillin. Or do I need to take a liquid antibiotic? Share this post Link to post Share on other sites
