- Avoid solid food and milk within 1–2 hr of administration, but should be adequately hydrated prior to, during, and after administration.
- Patient should be allowed only clear liquids after administration.
- May be administered on the morning of the examination as long as time is allotted to drink solution (3 hr) and evacuate bowel (1 additional hr). For barium enema, administer solution early evening (6 pm) prior to exam to allow proper mucosal coating by barium.
- Oral: Solution may be reconstituted with tap water. Shake vigorously until powder is dissolved.
- Follow 2 dose regimen for Suclear™.
- May be administered via NG tube at a rate of 20–30 mL/min.
- Instruct patient to drink 240 mL every 10 min until 4 L have been consumed or fecal discharge is clear and free of solid matter. Rapidly drinking each 240 mL is preferred over drinking small amounts continuously.
- Advise patient to avoid alcohol during prep.
- Diarrhea, which cleanses the bowel within 4 hr. The first bowel movement usually occurs within 1 hr of administration.
