Hello all. I am suffering from chronic sinusitis with recurring bouts of bronchitis. There’s my doctor that is always giving me the exact same Z max antibiotic each time when it is recurring and that’s because I have found out some years ago that I am having allergies from penicillin. The last 2 times when I have got sick he has had to refill my script and I have been down for approximately 3 weeks or so. I am honestly thinking right now that the antibiotic is not working for me anymore. I have taken it, and the same antibiotic, way too many times, so I am feeling that my body has grown up tolerance to it and now it doesn’t touch me anymore. I have heard that antibiotics tolerance isn’t a myth and is true and unfortunately for me, I have read that antibiotic tolerance is a bitch! Anyway… I would really like to know if there is anybody else who might be having similar problems as I do or maybe have had any good results with some other non penicillin based antibiotic? I am thinking that there should be some other anitbiotics than azithromycin and penicillin doing a good job for sinusitis, no? if there are some of you who can give me any suggestions I would be very and very thankful to you. I just want to go and make some suggestions to my doctor the next time I am getting sinusitis. I do know that there might be something wrong only now at the moment and maybe later the azithromycin might work later, I am not sure, but if it won’t I want to have that something ‘prepared’ so the next time I could already be using it, not starting to search for it. thanks in advance for everything.
