Treatments and drugsBy Mayo Clinic Staff
You may need to be hospitalized for peritonitis that's caused by infection from other medical conditions (secondary peritonitis). Treatment may include:
- Antibiotics. You'll likely be given a course of antibiotic medication to fight the infection and prevent it from spreading. The type and duration of your antibiotic therapy depend on the severity of your condition and the kind of peritonitis you have.
- Surgery. Surgical treatment is often necessary to remove infected tissue, treat the underlying cause of the infection, and prevent the infection from spreading, especially if peritonitis is due to a ruptured appendix, stomach or colon.
- Other treatments. Depending on your signs and symptoms, your treatment while in the hospital may include pain medications, intravenous (IV) fluids, supplemental oxygen and, in some cases, a blood transfusion.
If you're undergoing peritoneal dialysis
If you have peritonitis, your doctor may recommend that you receive dialysis in another way for several days while your body heals from the infection. If peritonitis persists or recurs, you may need to stop having peritoneal dialysis entirely and switch to a different form of dialysis.
