Welcome to Healing Well! Thank you so much for sharing your experience with me. Fortunately, I had the sense (with the encouragement of my husband) to take a traditional Z-pac instead. I have actually ended up in the hospital with symptoms similar to what you're experiencing. I also have asthma, and when I got my stomach going, it caused increased GERD and I ended up needing to be hospitalized so they could keep me breathing.
Your warning has made it easy for me to never even consider using it in the future. Anyone who has a tendency toward GERD and/or a sensitive stomach needs to steer clear. The doc who offered it doesn't know me well enough yet, or he wouldn't have suggested it. It's being offered free at the moment, and it was tempting, but the generic z-pac is cheap.
I got into horrible problems like the ones you're describing whenever I've taken Augmentin. If you get any reflux at all, and get a roiling gastritis, you will get a burned esophagus. It will take a long time and careful eating to get yourself back to normal.
I hope you feel better very soon!
