(1) Start Low.
The ultimate way to prevent nausea and vomiting during colonoscopy prep. is to avoid Drinking too much colon prep. too fast.
you should try a “test drink” of your colon prep liquid. If you can tolerate it then start increasing the second dose.
Most colon prep. doses are usually about 2- 4 liters. and you can drink it in 2 sessions (1-2 Litre/session).
We recommend you to start as low as one or two Fl. Oz. (30-60 mL) as a test dose, if no nausea or vomiting, you can drink a bigger amount 15-20 minutes later.
(2) Go slow
Don’ t consume the whole dose of your colon prep. solution as a single dose. rather split them into 2 doses:
- The first dose: the night before colonoscopy.
- the second dose: 4-5 hours Before colonoscopy.
For each dose, you can expand the time of drinking. For example. instead of drinking your first dose over 15-30 minutes, try to drink smaller amounts over a longer period over 1-2 hours) [ref]
