Zithromax Z-Pak and nauseous

I went to dentist to extract a tooth instead he gave pain meds and zpac to reduce the inflammation and referred me to an oral surgeon. First time I took it (which two tabs) I was sick to my stomach, nauseous with vomiting. I'm on day 4 now. I'm scared to death to take it on an empty stomach since I cant hold any food down, plus I need pain meds after i had my extraction which is super strong. Now I have a never ending battle. Cant wait for my mouth to heal so I can have a normal life again.

Went to doctor because of burning in throat and chest and nausea. Friend had the flu and I was starting to feel the same.

Doc diagnosed fluid on ear and swollen lymph nodes. First two days os zpak diarhea set in; next day chest in severe pain; next day feeling weak and spacey; today nauseous all day - breathing bad and throat tight and headachey.

This has done nothing for the nauseousness which doc said was due to sinus drainage. Sinus got worse with white yeast material getting spit out. Yeast of course is fungus----so appears that the zpak has created yeast in the upper respiratory area rather than curing the fluid it is now congealed into white stuff.

One more pill to take. Do I take or not?

Also, told ht edoc I was allergic to erythymycin----so she prescribed zpak---------is this not the same as erythromycin?

If this is the same then I am not surprised that I am feeling bad on this medication.

Never again on z pak.
