Amoxicillin (Amoxil; Biomox; Polymox) Forum Forum - bloody stool

[Guest]

I have been using Amoxicillin for about 5 days, and in the last couple of days have developed stomach cramps and very watery diarrhea.<BR><BR>I called the doctor's office today and they told me to discontinue it and call if it persists or if the original ailment does. <BR><BR>Tonight I noticed the stool, was very red, quite like blood (I've seen this on many web searches as a potential side effect). I called the doctor's office again, and they suggested waiting till morning. It's quite alarming...how concerned should I be? Are there any short- or long-term concerns with this having happened?<BR><BR>Thanks,<BR>Lindasko

Why are you on Amoxicillin? I have been on Amoxicillin for the past 7 days, and I too experienced very painful cramps and bloody stool and diarrhea on the 5 day. I am going to the doctor today, hopefully they can shed some light on it.

It's a long time since I posted...sorry I never saw your reply. <BR>For what it's worth, I was on it for an ear infection. Considering the doctor I saw at the walk in clinic (not my regular GP) seemed to think it was amazingly rare, I find it interesting that you, too, had the same reaction.<BR><BR>I guess like allergies you can develop reactions to things that didn't bother you before? I've used Amoxicillin once or twice over the years, without any problems.<BR><BR>The doctor just told me to discontinue use, and to use Imodium for a day or two.
