Zithromax Z-Pak and second time

Taking Z-pak for the second time this week. Each day has gotten worse. I take them at night, figuring that the worst of the effects would be during my sleep. Well, that's not so. Starting about 9am each day, I get horrible dry mouth, chills, and pain in my chest that rivals any pain I've ever felt. I have trouble eating and I feel super weak - including some tingling/pins and needles in my hands and feet. It usually goes away by about 6pm and I start feeling better. I do take my Claritin at about 8am every day. Could there be an interaction? It seems odd that I feel OK on waking up, but feel terrible for hours after taking the Claritin while on the Z-pak. Has anyone ever experienced this? Any advice on how to handle it? I have company in this weekend and I can't even function to entertain them!! Thanks!!

this is the second time i have taken the zpack for bronchitis...first time no symptoms, this time however......i am having verrrrry dark brown/ red urine, diarrhea, headache, stomach cramping, and body sweats....i don't know if this is due to my illness or due to zpack, but i HATE these symptoms/side effects

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!!!

I've taken Z-Pak only twice in my life. The first time I had a bad headache for the whole time taking it. The second time was horrible (probably worse because I didn't eat food with it this time)! I was in bed all day long with a severe migraine, vomiting, and feeling severely fatigued. Ive never felt like that before in my life. It was like my body was shutting down. I couldn't even eat anyting until late that day. I stopped taking it right away. Now I always ask for amoxicillan.
