Key takeaways
PEG 3350/electrolytes (Golytely, Nulytely, and Moviprep) and bisacodyl (Dulcolax) are both used to help with bowel movements, but they work differently and are used for different purposes. PEG 3350/electrolytes is an osmotic laxative used to clean the colon before procedures like colonoscopies, while bisacodyl is a stimulant laxative used for occasional constipation. PEG 3350/electrolytes is a prescription medication, whereas bisacodyl is available over-the-counter. PEG 3350/electrolytes requires you to drink a large amount of liquid, which can be time-consuming, and it can cause side effects like nausea and electrolyte imbalances. Bisacodyl is taken as a tablet once a day and usually works within 6 to 12 hours, but it can cause belly discomfort and cramps. You should not take bisacodyl with milk or antacids, as they can interfere with how it works. While PEG 3350/electrolytes is used for bowel prep, bisacodyl is not recommended for long-term use and should not be used for more than a week without consulting a healthcare provider.
