Camptosar and Imodium
If you are undergoing treatment with Camptosar® (irinotecan), there is a high risk of developing "late-onset" diarrhea. This is diarrhea that occurs more than 24 hours after an infusion of Camptosar. If this occurs, Imodium® (loperamide) or other similar products may help.
Imodium, or other similar products, should be taken at the first sign of loose or frequent stools. Your healthcare provider will tell you how much to take. Make sure to contact your healthcare provider if diarrhea continues for more than 24 hours, or if you feel like you are becoming dehydrated. This can lead to potentially life-threatening complications, such as kidney failure and electrolyte problems.
