Sinusitis
"I was put on the z pac it is the one you take for 5 days ,for sinuses. I would not recommend it if you are like me and have reflux or stomach issues. I had taken it before, however this time there was more symptoms and side effects than ever before, I think they changed some things in this pill. I took the first day  1 one tablet about 12 hours apart not the two together. I have a very acidity feeling and bad diverticulosis in my stomach.  After the 3 pills got hives on my leg after I took the second one started to feel nausea so bad and chills, as well as terrible diarrhea and it cleared up the sinus infection some but it is tearing my stomach to pieces even after eating before I take it. Reported the hives to the doctor he said keep taking I did and I am itching again"
