Preparing for a procedure

Avoid:
Whole grains, seeds, nuts, fruit and vegetables (especially skins/seeds), red or purple foods/drinks
Step 2: Day Before Procedure
Switch to Clear Fluids Only
Water, clear broth, apple juice, black tea/coffee (no milk), electrolyte drinks (avoid red/purple)

You will take Plenvu in two doses (split dosing).
Dose 1 – Evening Before (around 6pm)
Drink Dose 1 of Plenvu as directed
Follow with at least 500ml of clear fluids
Continue drinking extra clear fluids to stay hydrated
