Laxative Medications After Transplant

Overview

Why would I need to take laxative medicines?

One of the common side effects of transplant medicines is constipation. If constipation becomes a problem for you, your doctor can recommend an over-the-counter (without a prescription) laxative that can encourage bowel movements to relieve constipation.

How and when should laxatives be used?

Laxatives are to be used only to provide short-term relief of constipation, unless otherwise directed by your doctor. Remember to check with the Transplant Team if you would like to use a laxative that has worked for you in the past.

Warning: If you have stomach pains, do not use an over-the-counter laxative without first talking to your doctor or a member of the Transplant Team.

When taking an over-the-counter laxative, carefully read the instructions and follow any precautions on the label.

Procedure Details

What special instructions should I follow when using this medicine?

  • If you have been prescribed a low-sodium or low-sugar diet, carefully read the ingredients listed on the label. Some laxatives contain large amounts of sodium or sugar, which could cause unwanted side effects.
  • Certain medicines might cause unwanted side effects when used in combination with laxatives. The use of laxatives containing magnesium might reduce the effects of some of these medicines. Please tell your doctor if you are taking any of the following before you start taking an over-the-counter laxative:
    • Oral anticoagulants (blood-thinning medicines)
    • Digitalis glycosides (heart medicine)
    • Ciprofloxacin (Cipro®)
    • Etidronate (Didronel®)
    • Sodium polysterene sulfonate
    • Oral tetracyclines (medicine for infection)
  • Do not take any laxative within two hours of taking other medicines, as you might reduce the desired effect of the other medicine.
  • Do not take any type of laxative for more than one week unless otherwise instructed by your healthcare provider.
  • Do not take any type of laxative if you do not need it; for example to “clean out your system” or to make you feel better.
  • Call your healthcare provider if you notice a sudden change in bowel habits or function that lasts longer than two weeks, or keeps returning off and on.

Recovery and Outlook

How do I prevent constipation?

To prevent constipation, you need to maintain a diet rich in fiber and drink at least six to eight 8-ounce glasses of fluids a day. Prune juice, whole grain breads and cereals, and fresh fruit and vegetables are all fiber-rich foods to include in your daily diet to help prevent constipation. A regular exercise program also can help you prevent constipation.
