Symptoms
By Mayo Clinic staffThe most common and the initial sign of pseudomembranous colitis is watery, and sometimes bloody, diarrhea.
Symptoms of pseudomembranous colitis include:
- Diarrhea
- Abdominal cramps and pain
- Fever, which may be higher than 101 F (38.3 C)
- Urge to have a bowel movement (fecal urgency)
- Pus or mucus in your stool
- Nausea
- Dehydration
Symptoms of pseudomembranous colitis can begin within one to two days after you begin receiving an antibiotic, or they may not occur until several weeks after you discontinue the antibiotic.
When to see a doctor
Contact your doctor if you're taking or have recently taken antibiotics and you develop any of the signs or symptoms associated with pseudomembranous colitis, including constant diarrhea, abdominal pain, and blood or pus in your stool.
