Zithromax Z-Pak and stomach

I am currently taking the z-pak, on my third day. Today I woke up with white "pockets" under my tongue. Thinking about not taking any more. They are very painful. Hurts to eat or drink. I've taken this before but never with this kind of reaction.

Took 4 doses out of five and I suddenly developed a rash on my stomach which lasted for a few days after I quit. Two and a half weeks later, the rash just came back randomly, redder, affecting more areas of my body like parts of my arms and neck. Hopefully my body's just flushing out what's left of this toxin.

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.

Like the rest of everyone else, the flu season hits and you want to get rid of your cold!!! Right. Right. Go to the doctors and they give you a drug.
Yes, I had taken the zpack for the 5 days and like everyone else, I have had all of the same feelings; depression, diarrhea, stomach ache, rash/itching, fullness in your ear or ringing, loss of taste-smell. Oh yeah, what a joy.
I called the Pharmacy to ask about how long I should experience this, it should go away in 10 days. Well, not as of yet...the loss of hearing and loss of taste. Not sure what would be the next step? Go to the doctor's and get more drugs, ie;more side effects.!? Anyone have the same side effects with your ears?

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.

Just finished the 6 day course of meds today and have had loss of appetite and have been feeling very drained energy-wise especially today...also have been feeling anxious and not able to concentrate too well...also some stomach upset...I've been on this drug before but this course has yielded more side effects than in the past...

Let me tell you guys It has been horrible for me.
a) My doctor gave me a Zpak for a strep throat it was gone in a few days.
But a few weeks later I had a stomach pains that would not go away so then the doctor did a test for H Pylori the antibody test came back positive so then I was on PrevPak(which has Azithromycin) after the 2 week period of these drugs I had a infection come up in my growing area, had burning pain for peeing. It sucked because I was on a trip to Universal Studios and was in Miami for New Years Eve. Well after this went away I had another infection come again in the growing and now its finally starting to go away after the doctor gave me some fugal pills and medications for it. What a nigthmare. With all this going I had diary and hemoroids nasty situation and normally have mouth ulcers so can you image the past two months have been hell for me!!!
