Ok to take imodium (loperamide) for post op diarrhea from gallbladder surgery?

Depends: When was your surgery? Would not want to combine immodium & narcotic pain pills. Best is to address the issue first with avoiding fried, fatty, greasy foods. Drink plenty of water. Check with your doctor or surgeon before adding medication like this. Immidium will not correct the cause if the diarrhea either & likely to have better results with prescription cholestyramine. See your doctor.
