Zithromax Z-Pak and severe abdominal pain

Had severe flu--suspected bronchitis and strep. Took z-pack. Immediately started to feel better. High fever, chest pain, aches gone. BUT now 1 week after I took z-pack, I have severe abdominal pain and diarrhea after every meal. Can't keep anything from immediately going out the other end. So miserable. I'm thinking the good flora was killed off in my intestines. Calling the doctor tomorrow.

Prescribed 3 day z pak after Thanksgiving 2004 for strep throat and sinus infection. Had severe abdominal pain during course and a couple of days afterwards. Also had swollen glands a few days after taking. Ended up back at the doctor for severe vertigo and headaches two days before Christmas. After all of the pain I went through the z pak did not clear up my sinus infection and I was put on another antibiotic.

Husband put in hospital on day 4 of taking this drug for SEVERE vomiting and diarrhea, lost 13 lbs in 3 days!, will be in hospital for AT LEAST 4 days! Have found out a young women (late 20's - early 30's) was put in hospital for SEVERE abdominal pain on day 3 of this drug treatment. BEWARE THIS DRUG!
