Treatment of proctitis depends on its cause. The goal of treatment is to reduce inflammation, control symptoms, and eliminate infection, if it is present. Only a doctor can determine the cause of proctitis and the best course of treatment. With proper medical attention, proctitis can be successfully treated.
                
Proctitis from Infection
                
If lab tests confirm that an STD or non-STD infection is present, medication is prescribed based on the type of infection found. Antibiotics are prescribed to kill bacteria; antiviral medications are prescribed to treat viruses. Although some STD viruses cannot be eliminated, antivirals can control their symptoms.
                
Proctitis from Other Causes
                
If antibiotic use triggered proctitis, the doctor may prescribe a different antibiotic designed to destroy the harmful bacteria that have developed in the intestines.
                
If proctitis is caused by anorectal trauma, the activity causing the inflammation should be stopped. Healing usually occurs in 4 to 6 weeks. The doctor may recommend over-the-counter medications such as antidiarrheals and those used for pain relief, such as aspirin and ibuprofen.
                
Treatment of radiation proctitis is based on symptoms. Radiation proctitis causing only mild symptoms such as occasional bleeding or tenesmus may heal without treatment. For people with persistent or severe bleeding, thermal therapy may be used to stop bleeding and inflammation. Thermal therapy is done during flexible sigmoidoscopy or colonoscopy and targets the rectal lining with a heat probe, electric current, or laser. Argon plasma coagulation is the most common thermal therapy used to control bleeding in radiation proctitis. In many cases, several treatments are required. Obstruction that results from a stricturea narrowing of the rectumcaused by radiation proctitis may be treated with stool softeners in mild cases. In people with narrower strictures, dilation to enlarge the narrow area may be required. Sucralfate, 5-aminosalicylic acidknown as 5-ASAor corticosteroid enemas can also be used to ease pain and reduce inflammation from radiation proctitis, although their effectiveness is limited.
                
When a chronic IBD such as ulcerative colitis or Crohns disease causes proctitis, treatment aims to reduce inflammation, control symptoms, and induce and maintain remissiona period when the person is symptom-free. Treatment depends on the extent and severity of the disease.
                
Anti-inflammation medications. Mild proctitis can often be effectively treated with topical mesalamine, either suppositories or enemas.
                
Some people with IBD and proctitis cannot tolerateor may have an incomplete response torectal therapy with 5-ASA suppositories or enemas. For these people, the doctor may prescribe oral medications alone or in combination with rectal therapy. Oral medications commonly used for proctitis contain salicylate. These include sulfasalazine- or mesalamine-containing medications, such as Asacol, Dipentum, or Pentasa. Possible side effects of oral administration of sulfasalazine- or mesalaminecontaining medications include nausea, vomiting, heartburn, diarrhea, and headache. Improvement in symptoms, including a decrease in bleeding, can occur within a few days, although complete healing requires 4 to 6 weeks of therapy.
                
Cortisone or steroids. These medications, also called corticosteroids, are effective at reducing inflammation. Prednisone and budesonide are generic names of two medications in this group. Corticosteroids for proctitis may be taken in pill, suppository, or enema form. When symptoms are at their worst, corticosteroids are usually prescribed in a large dose. The dosage is then gradually lowered once symptoms are controlled. Corticosteroids can cause serious side effects, including greater susceptibility to infection and osteoporosis, or weakening of the bones.
                
Immune system suppressors. Medications that suppress the immune systemcalled immunosuppressive medicationsare also used to treat proctitis. The most commonly prescribed medication is 6-mercaptopurine or a related medication, azathioprine. Immunosuppressive medications work by blocking the immune reaction that contributes to inflammation. These medications may cause side effects such as nausea, vomiting, and diarrhea and may lower a persons resistance to infection. Some patients are treated with a combination of corticosteroids and immunosuppressive medications. Some studies suggest that immunosuppressive medications may enhance the effectiveness of corticosteroids.
                
Infliximab (Remicade). Researchers have found that high levels of a protein produced by the immune system, called tumor necrosis factor (TNF), are present in people with Crohns disease. Infliximab is the first of a group of medications that bind to TNF substances to block the bodys inflammation response. The U.S. Food and Drug Administration approved the medication for the treatment of moderate to severe Crohns disease that does not respond to standard therapiesmesalamine substances, corticosteroids, immunosuppressive medicationsand for the treatment of open, draining fistulas. The medication is also given to people who have Crohns disease with proctitis. Some studies suggest that infliximab may enhance the effectiveness of immunosuppressive medications.
                
Bacterial infection can occur with flare-ups of ulcerative colitis or Crohns disease. Antibiotics may also be used to treat flare-ups in people with IBD and proctitis.
