bacterial infection
"I took this medicine for about 3 days - 4 times a day. I notice that  I  have severe chest pains and I'm only 19. So I let it go on and it got way worse!!! I started to have very bad diarrhea. I thought nothing of it until I began seeing blood in my stools. I went to the hospital as everything progressed and they told me to stop taking the medication and prescribed me a medication that can reverse these symptoms. I advise everyone who reads this to not take this medication. And really if they can report all of these issues why has this medication stopped being produced, it makes no sense to produce a medication that is virtually going to kill you?"
