To Prevent or treat constipation your doctor or nurse may recommend the following schedule of laxatives and stool softeners. DO NOT TAKE ANY MEDICATIONS UNLESS INSTRUCTED BY YOUR DOCTOR OR NURSE.

  • Routinely take 2 tablets of Senekot-S® at bedtime. This can be increased by your doctor or nurse to 2-3 times per day, if needed.
  • If you have not had a bowel movement for 1-2 days (days 1-2):
    • Continue the Senekot-S®
    • Take 2 tablespoons of Milk of Magnesia at dinner time and bedtime

  • If no bowel movement by the next morning (day 3):
    • Continue the Senekot-S®
    • Take 2 Ducolox® tablets 3 times during the day and at bedtime

  • If no bowel movement by the next morning (day 4):
    • Continue the Senekot-S®
    • Contact your doctor or nurse who may instruct you take 1/2 - 1 bottle of Magnesium Citrate in the morning
    • If still no bowel movement by the afternoon, contact your doctor or nurse again. You might be instructed to take a Fleet's® enema or Ducolox® suppository, unless your white blood cell or platelet count is low

  • If no bowel movement by the next morning (day 5):
