I've had a sinus infection for 14 days. I was put on zithromax because it was one I could take with wellbutrin (generic form) xl. It isn't working however. When I research other antibiotics typically given for sinus infections, all of them say to not be taken with wellbutrin xl. Has anyone else run into problems with this? Decongestants also should not be taken so it has been a rough 2 weeks. Thank you!
