Medications If radiation enteritis persists despite changes in your diet, it may be necessary to reduce the daily dose of radiation to the abdomen and pelvis. You may also have to use medications such as:
• Kaopectate (2 to 4 tablespoons/25 to 50 mL after each loose bowel movement).
• Lomotil (one to two tablets every four to six hours as needed to a maximum of eight tablets a day). Most patients find they need only two or three tablets per day after the diarrhea has been controlled.
• Imodium (two capsules initially, followed by one capsule after each loose stool , the total dosage not to exceed
16 capsules per day). Imodium is also available in a liquid form (half-dose strength) that does not require a
prescription.
• Donnatal or Robinul (one or two tablets every four hours for abdominal cramping).
• Paregoric (1 tsp./5 mL orally every four hours for diarrhea).
• Compazine (10 mg every four hours), Ativan (1 mg every two to four hours) or Reglan tablets or liquid (10 mg
four times daily, 30 minutes before each meal and at bedtime) can usually control nausea.
