Absolutely typical. My dr told me to up the probiotics when she gave me meds for my sinus infection 2 weeks ago.

I'd call the doctor and see if they can switch the antibiotic to one less likely to cause these symptoms. Definitely, though, get the most powerful probiotic you can find at Whole Foods. Take it two to three hours away from the antibiotic.

Sorry, but pretty typical. Get a probiotic and take it several times a day. Make sure you are taking the antibiotic with food.

Also, take some mucinex to help alleviate the nasal symptoms. Drink lots of water and do sinus rinses

Call your doctor and ask. The reaction might be temporary.

So after feeling bad for at least a few weeks I finally gave in and took the Rx my doctor gave me and I am having the worst GI symptoms. I will try to get a probiotic today but what can I do to get past this. I am having diarrhea and feel like I might vomit and my sinuses still hurt. I am miserable!
