Hi Frank, NAC stands for N acetyl cysteine, an amino acid, but AAC is geprafloxacin, an antibiotic and not the same thing. You can find out more about NAC here:
I will send you by private message a list of supplements used, including NAC and a good probiotic. They all come from the same place in the USA, which I find is a very cost effective way to buy supplements in the UK at the moment, as long as you don't just order things one at a time. I don't know how that applies to Germany.
Since you are in Germany you will be able to get roxithromycin in place of azithromycin. You take 2 x500mg a day, either together or separately. It is much more tolerable than azithromycin.
Also tinidazole is much more tolerable than metronidazole. I take that as well. It is called Fagisyn and manufactured by Pfizer, still under patent and so a bit more costly. I don't know why it is presently not available in Germany: maybe it isn't here either, but I only take abx for two weeks every three months now. It might be just a manufacturing problem. You won't need it for at least three months, though.
I'm sorry I didn't see you, Frank, I'm sure I looked more recently than nearly a week ago, and as Colin says, good luck with your treatment!
