Hi there, I have to take Azithromycin 3 times a week, I was fine at the start then my giblets really started playing up and I got terrible stomachache too. I begged to stop antibiotics but doctors said please don't.
I now take an ultra strength probiotic. Apparently it is important to have at least 10 different probiotic strains and more than 20 billion live cultures. You have to check the use by date, buy the freshest possible and keep in fridge once open. The good ones are expensive, but prices do vary. Apparently not all probiotics are equal, and some of those sold will do absolutely nothing.
These have not cured my giblet problems, but have gone from a 7 day a week problem to on average 3 days.
What's so annoying about this is that the doctors themselves seem to know nothing about the which are the right probiotics, and don't care about my tummy as long as my lungs are good. I got my best advice from a super good pharmacist. ( but even they are a bit random)
I don't know if Azithromycin is better than Docycline. But I do know that what they give you depends on what has infested your lungs. So it may be the best one for you.
