Oral solutions used for bowel cleansing before a colonoscopy can sometimes lead to significant nausea or vomiting. Should these symptoms occur, it is recommended to pause medication intake for a brief period of 30 to 60 minutes. Following this pause, medication should be resumed at a slower pace. Sipping the solution more gradually may help prevent the recurrence of nausea. Additionally, the use of anti-nausea medication can be considered after consulting your doctor. A practical method to help reduce gastric discomfort is to consume the medication chilled or alongside cold beverages.
