Plenvu is the first 1 liter PEG-based bowel cleansing agent. Plenvu can be used alone or in conjunction with over the counter laxatives like bisacodyl or magnesium citrate. If an over the counter laxative is also recommended by your physician, it is usually used about 1 hour before the bowel cleansing agent.
