Zithromax Z-Pak and medicine

I was prescribed z-pak for a horrible cold I had. Immediately I had stomach cramps, horrible pain that would come and go...but I kept taking the medicine. Each day the stomach cramps were worse than my cold. By day 5 I broke out in a rash on my upper chest, shoulders and upper back...they were like pimples that itch. I am assuming since the zpak stays in your system for 10 days that this stomach pain and rash will continue. PLUS the zpak has not helped my cold/cough. I will never take the z-pak again and told others to never take it.

This is my second day w/ Z-Pak. Almost immediately after taking the first dose it felt like someone had punched me in the stomach. I had been feeling so bad though for 2 weeks + I just figured it was probably just from being sick anyway. Well, I had extremely vivid nightmares that woke me up several times last night, followed by an odd feeling of dread or anxiety. I didn't realize these were common side effects and just chalked it up to something I could've possibly seen on tv earlier in the day. Today since I've been awake I've had a terrible headache, and my stomach (while I haven't used the bathroom at all) still feels like I've been punched, only the pain is more severe. I didn't think any medicine could have side effects that worked this fast, which is what let me to even looking up this medication online. I never experience side effects from medicines and have never had an allergic reaction to almost anything I've taken. This is extremely weird for me. I'm having a terrible time trying to make it through the day, and the anxiety/fear/dread just seems to get worse by the hour. So far it hasn't really taken away my symptoms for bronchitis, but i'm hoping after a couple more days i'll feel better....

started Zpak last week for a lingering sinus infection. I live in an area where the weather changes constantly. Two days after I finished the 5day Zpak I began experiencing horrible and flu-like symptoms and worse. I can hardly breathe out of my nose. Heavy chest congestion. Lots of diarrhea and even blood in the stool one day. Taste buds are gone. Here I am a week after finishing the Zpak feeling HORRIBLE. I'm afraid to go back to the doctor (uninsured) only to be prescribed something else that might bring on more side effects. Right now I'm taking Sudafed PE and hoping that kicks it. I've been on a Zpak before but NEVER had side effects like this. I don't wish this on anyone. and I'm wondering how long the Zpak stays in your system? It is possible to make you sicker? Seems so in my case and many others here.

Zithromax/Z-Pack does give you the cramps and diarrhea only side effect i got, but it pushes the infection out of your body,this medicine does work.

Started the z pack for bronchitis and sinus infection. First symptoms was stomach cramps, diarrhea. The next and most disturbing symptoms were extreme agitation, anxiety, depression. Have finished the last of the medicine 4 days ago and am still feeling the residual anxiety, agitation, general feeling of unease. Will never take this medicine again.
