Zithromax Z-Pak and sore throat

Day 2 (took double dose yesterday, single dose today) -- have developed pretty constant diarrhea and stomach cramps. This week has sucked. I have suspected strep, fever, bronchitis and some kind of flu? I just spoke with my doctor who says that it can't be the drug since it's only the second day. Well, your comments here and other web research offers a different opinion. The doc is blaming in on my flu, but I didn't have any stomach distress at all until now. I'm hypothyroid, hypoglycemic and very sensitive to medication. The last thing I need is to have to deal with diarrhea. It sucks because my sore throat has improved, and so has my breathing, but I get dizzy when loosing fluids, no matter how fast I replenish. Female, age 35.

I've taken Zpak twice in my life. Once for bronchitis, it was helping right away.(within a few days). Second time for a sore throat and ear pain I was having for 2 weeks. By the 3rd day I was felling good again. I have nothing bad to say about the drug. I think it is the BOMB!!! Though I never had any side effects to the drug,
I would take a little diarrhea and nausea over bronchitis ANY DAY!!!

Extreme nausea whether eating or fasting on this medication. Plan to discontinue it now on day three. It seems to be making me feel worse than the original ailment which was the flu with sore throat and fever.

I was given z pak for my sinus infection,after the 3rd day just before my last dose i started getting a sore throat. I thought it was just dry. The next day it was worse & over the next 3 days got so bad i coulkdnt eat & my ear hurt so bad i thought i had an ear infection.Well i went back to the dr. I now have sores in my throat on the left side way in back,like canker sores & they hurt .I never have had anything like it before. I was not having any throat problems till i took z pak not i dont know what's going on it's weird.I dont think i'll take it again.
