My doctor put me on antibiotics because I have a bad chest cold and fluid behind the ears and she doesn't want it to turn into bronchitis which is going around alot right now. I have the generic form of this antibiotic. My question is has anyone who has ibs-d ever taken this and tolerated it ok? I am so nervouse about taking anitbiotics since alot of times their side effects are the big D. I dont need that side effect anymore than I already have it. One good thing is while Iwas in the hospital back in June I had 2 rounds of antibiotics and didn't have any issues with my ibs acting up at all. So lets hope this will turn out the same. I will be taking 500mg tonight and then 250mg for the next 5 days. Anyone have any experience with this med I have never taken it before.
