Zithromax Z-Pak and stomach cramping

Just took the first dose of the Z-pack (the two pills) on a full stomach and I feel like I'm going to die. I've been through the pain of childbirth and this can almost compare...the stomach cramping is severe and the diarrhea is immediate (you know, the "peeing your poop" kind of thing). When the cramping began, I got cold sweats...I'm still up, unable to sleep, because the stomach pains are SO bad. I know you're supposed to keep taking the pack but I am so ill I can't even imagine doing so right now. I had a similar reaction to Z-pack in 2004 but thought it was because I took a dose on an empty stomach. This confirms that it can happen anytime.

I'm taking the Z-pack to get rid of a sore throat. This is terrible. I'm almost in tears. :( I wish I could just throw up but my throat hurts too bad. I'm allergic to penicillin, so this was what the doctor prescribed. :(

I took my second dose last night (I'm on the 5 day course again). No side effects except a little stomach cramping which only lasts for a little bit. I love the ZPACK! It works fast too!

I get some stomach cramping from the Z-Pak, but the most disturbing side effect would be the chest pain. I have swollen glands right now and I had vertigo and the doctor told me it was probably a bacterial infection because the gland under my chin is the one that is swollen. Every time I take this medication the side effects are different. I also had the agitation the last time I took Z-Pak. Sometimes I have had the lose bowels, especially after taking the two pills together the first day. Well, I guess it is better than having an infection so I will continue to take it. There are other medications that are worse for me. At least I am not getting a rash and I cannot take penicillin.

This was the only thing that stopped pneumonia for me when I was six and now I'm on it again for bronchitis or something. I've had severe stomach cramping. My heart has been racing since I started taking it. I'm on my fourth of five days. I'm wondering if my heart is unrelated, meaning I should go see what I can do about that, or if it makes other people all jittery/anxious with a really high pulse.

I have taken Z-paks before without any problem. This time I took the 3 pill dose. I have horrible stomach cramping and diarrhea. I also broke out with a rash on my chest - tiny blisters that itch. I finished it today and hope this goes away soon.

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
