For some, the answer to how long does colonoscopy prep take to work, happens in about an hour. Diarrhea comes on, and then boom, nonstop until clean.

In Osmo-Prep (the newer form), the tablets are taken the evening before and the morning of the colonoscopy. The evening before the test, 4 tablets are taken with 8 ounces of a clear liquid every 15 minutes for a total of 5 doses (20 tablets total). The next morning, about 3 to 5 hours before the test, another 3 doses of 4 tablets are taken at 15 minute intervals (12 tablets total).
