Blood in the stool symptoms and conditions

started Zpak last week for a lingering sinus infection. I live in an area where the weather changes constantly. Two days after I finished the 5day Zpak I began experiencing horrible and flu-like symptoms and worse. I can hardly breathe out of my nose. Heavy chest congestion. Lots of diarrhea and even blood in the stool one day. Taste buds are gone. Here I am a week after finishing the Zpak feeling HORRIBLE. I'm afraid to go back to the doctor (uninsured) only to be prescribed something else that might bring on more side effects. Right now I'm taking Sudafed PE and hoping that kicks it. I've been on a Zpak before but NEVER had side effects like this. I don't wish this on anyone. and I'm wondering how long the Zpak stays in your system? It is possible to make you sicker? Seems so in my case and many others here.

After I switched to Metoprolol Succinate ER, the generic form of Toprol XL, which I had used for 4 years with no noticeable side effects, I began having the experience of everything moving faster - heart beat, pulse, intestinal peristalsis was highly accelerated. Daily bowel movements increased from one or two normal a day to three or four. After a few weeks this condition was punctuated by brief bouts of diarrhea(not something I am prone to) approximately weekly.

Since nothing else changed in my food, supplement or prescription drug intake, my digestive system has always worked extremely well, without problems; and because I had a colonoscopy showing no abnormalities in recently years and no occult blood in the stool in a recent doctor's visit, I am wondering if the Metoprolol is the cause. My entire system feels like it is on some type of "speed' drug, sort of a mania experience.

Have there been other reports of this with people who switched from Toprol Xl to the generic?

My son is being treated for an ear infection and this is his first time on omnicef. I have noticed day #2 and my 15 month son's stools were maroon colored. My first thought was blood as well, but I was told this is a normal reaction for omnicef to turn bowels orange or maroon colored resembling blood due to reaction with iron in the diet. The pediatric nurse assured me that this is normal and they look for symptoms such as bright red blood in the stool,black stool, and abdominal pain. My son's appetite is good and he is now after day #2 afebrile and doing just fine. However, I will continue to be observant.

Started taking Ominicef 300 mg. for upperrespitory infection
and Bronchitis on Dec 17,2005 dose 2 300mg tabs daily,
I developed extrime diaharea, which continued for 5 days, I was supposed to take this for 7 days, on the 5th day I developed an extemely sore throat which felt like a boil in my
throat, went back to the Dr. and had blood tests done I had
noticed a coffee ground effect coming from the stool, the test
showed that I was bleeding internaly and there was blood in the stool. The doctor had me stop taking it, I have just started to have normal looking stools, but this extreme reaction has
left me very weak,due to the extreme loss of fluid and blood

My 4 yr old son was given Omnicef for pneumonia. After a few days, i saw what i thought was blood in the stool....his stools have all been soft, but not diarrhea and also full of mucous. my son dances around crying to have a bowel movement and it breaks my heart. i called his ped who told me too that it was the dye in the med, but hello, the med is white. I have definately seen blood in his stool...bright red. i looked at the website for Omnicef and it says if you see blood in the stool or mucous to stop using it. He's almost done with it so i am going to stop it. My daughter is 2 and is on it as well and so far, no blood in her stool. this stuff is scary. Does anyone know if the blood goes away after you stop this or do you need to seek medical attention?
