skin or soft tissue infection
"I took 1 pill and about 6 hours later, I was getting out of my car and woke up on the sidewalk. I had passed out with no warning signs or symptoms. I passed out again within 2 minutes of the first time. I went to the local Urgent Care and after speaking to the doctor, he believes it was a side effect of the zpak. That is the only change in any food, drink or medication for weeks. I was not overheated and I was hydrated prior to passing out."
