Another GP who has not read the guidelines on bronchiectasis. Grrrr.
Unfortunately I cannot tolerte Azith and so like you have frequent infections.
I find Amox is just fine if I am culturing strep p for example (unpleasant but a gram positive bug and much easier to treat,) but it would be in a high dose and certainly longer than a week - usually 14 days.
It may be an idea if you don't improve to get a sample off to check what this bug is you are growing and also what it is sensitive to. Also you could say something like 'as you know with bronchiectasis the guidelines state to get a sample off but to start on a high dose antibiotic for 14 days or until the culture comes back with a different ab'. I've done this and they are not going to say they don't know, even if they don't. Just an idea. BTW the ERS are in the process of updating the guidelines and will form part of our meeting at the 2nd Bronchiectasis Cenference in July. They will be launched at the Int. Resp. Congress in September.
Good luck - be your own advocate.
