Ready, Set, prep!

MiraLAX is a laxative, providing effective and predictable relief for occasional constipation. MiraLAX is clinically proven to relieve occasional constipation and soften stool without causing harsh side effects such as sudden urgency, cramping, bloating, and gas. MiraLAX powder dissolves completely in water or any hot or cold beverage of your choice with no added taste or grit.

🎥 Make sure to watch our MiraLAX Preparation Video! It will give you step-by-step instructions on how to properly prep for your upcoming procedure.

The Day before your procedure

You may have clear liquids only.

Between the hours of 8 am-12 pm drink one 10z bottle of magnesium citrate


🚫 NO candy or gum, as well as refrain from smoking, vaping, and using any tobacco products, illicit drugs, or cannabis, including medical cannabis. 

If you consume any of these after midnight, it will result in having to reschedule your exam.


* Remember it is important to drink plenty of clear liquids before and during the colon prep process to properly prepare for your exam.

The Night Before your procedure

At 4 pm, take 4 Dulcolax laxative tablets (purchased over the counter)

At 5 pm, pour the entire bottle of Miralax into 2 quarts of Gatorade or crystal light. Stir it until it is dissolved and put it in the refrigerator.

At 6 pm, take one antinausea pill

Then drink ½ of the Miralax solution within 1 hour, place the remainder back into the refrigerator overnight.

After you finish the first 1/2, you may maintain clear liquids until midnight as tolerated

The Morning of your procedure

At the time you were given by our staff, drink the rest of the Miralax within an hour.

Once you finished, it is nothing to eat or drink until after your procedure.
