Not sure why you need antibiotics. Same thing had happened to me and I never received antibiotics for it. Ask your doctor for the reason.

Have to agree. A doc should not rx abx w/o seeing you, certainly not if your primary symptom is blood in the stool. That COULD indicate bacterial infection, I suppose, but it is not the first thing one would consider in those of us with serious gi conditions. Especially considering the incredible sensitivity of our systems, antibiotics are likely to cause more problems. Not to mention, too many antibiotics can cause further immune issues down the line.
Personally, I would not take that prescription until I got a real good answer as to why he wanted me on it. I'd want to be seen to at least check for a hemmorhoid or fissure, probably get a stool culture to be sure of infection and type before treating it.
If, on the other hand, you have other symptoms indicating infection, like a fever, and are prone to a specific type of infection, that may be a different scenario. But you would not be asking us, and even if it were the case, new symptoms are not good in that scenario. As an example, I'm thinking of myself, who up until I was almost 22 had nasty, recurring sinus infections and had even had surgery. If I had fever, sore throat, jaw pain, and colored mucus, my doctor would call in an rx for me without a thought. However, if any of those symptoms were not there or I felt something was 'off,' she would insist on seeing me to be sure I had the same infection or might need differnt treatment. Good luck, I hope you feel better soon.

thanks for replying. I didn't think to mention it was late sat pm. and sometimes I am not sure if it's a emergency. The doctor said antibiotics were for possible infection if I couldn't or wouldn't or got to er thanks

I agree with the others, blood is not an indication of a need for antibiotics without symptoms or tests for infection. Antibiotics can cause other problems. Please check back with your doc.

I agree, antibiotics can cause more problems if not diagnosed properly. A doctor should see you before prescribing them. If you currently have UC or Crohns, then antibiotics will cause you to flare and can even cause C-Difficil which can be very bad. When I had UC and started bleeding I would be prescribed Canasa suppositories (if in the rectal area) and/or prednisone (steroid). The doctor never prescribed antibiotics unless absolutely necessary because it causes flares and C-Diff. After I had my colon removed I was able to take antibiotics aging without much problem. With having a j-pouch it is more common to get antibiotics because it doesn't really hurt anything (I no longer have UC though and I am considered "cured", may not be the same for those with Crohns). Usually, I just get a script for Canasa suppositories and that takes care of my cuffitis and antibiotics help pouchitis. Hope this helps.

I have had UC for ~15 years. Have always ended up treating flares with the dreaded prednisone. Last January my GI prescribed an antibiotic - Flagyl. It worked like a charm. So don't dismiss the thought of antibiotics. Yes, it's a good idea to make an appointment with your GI - mine would set up an appointment if I called in with a flare.

The flagyl worked for me Jan of last year, I had another flare in May of last year and tried flagyl again - it did not have the same effect. Ended up taking prednisone for that one. I would think antibiotics would be safer than prednisone.

There are certain antibiotics that can cause a flare of UC, you have to be really careful - when you visit a regular PCP or dentist you should mention you have uc or Crohns so they know which antibiotics to avoid.

In many ways, you are correct. I would have to agree that generally speaking, abx are safer than prednisone in that for MOST of us, the side effects are far milder and there are far fewer risks of lasting damage.
However, the danger with antibiotics is the potential for 1)also killing GOOD bacteria, which is particularly common and unhelpful for those of us already having intestinal issues, and 2) if there is no infection or you are on the wrong antibiotic for the infection you do have, the odds are much higher that you will create a 'superbug' and either a new strain of resistant infection is created and spread, or more commonly, the antibiotic does not work for you the next time around when you do need it.
Such a delicate balance and serious ramifications. There's one reason I wont ever become a doctor!
