There are two dosing regimens, each requires two separate dosing times:
Split-Dose Dosing Regimen (Preferred Method): The Split-Dose regimen is the preferred dosing method. Instruct patients to take two separate doses in conjunction with fluids, as follows:
- Take the first dose (1 bottle/1 sachet) during the evening before the colonoscopy (e.g., 5:00 to 9:00 PM) followed by 1200 ml liquid (5x 240 ml) drinks (using provided measuring cup) of clear liquids before bed. Consume clear liquids within 5 hours.
- Take second dose (1 bottle/1 sachet) the next day approximately 5 hours before the colonoscopy followed by at least 720 ml (3x240 ml) drinks of clear liquids before the colonoscopy. Consume clear liquids within next 5 hours but atleast 2 hours before the time of the colonoscopy.
Day-Before Dosing Regimen (Alternative Method): The Day-Before regimen is the alternative dosing method for patients for whom the Split-Dosing is inappropriate. Instruct patients to take two separate doses in conjunction with fluids, as follows:
- Take the first dose (1 bottle/1 sachet) in the afternoon or early evening (e.g., 4:00 to 6:00 PM) before the colonoscopy followed 1200 ml (5x 240 ml) using provided measuring cup of clear liquids before the next dose. Consume clear liquids within 5 hours.
- Take the second dose (1 bottle/1 sachet) approximately 6 hours later in the late evening (e.g., 10:00 PM to 12:00 AM), the night before the colonoscopy followed by at least 720 ml (3x240 ml) drinks of clear liquids before bed. Consume clear liquids within 5 hours.
- Additional fluids must be consumed after every dose in both dosing regimens.
- Instruct patients to consume only clear liquids (no solid food or milk) on the day before the colonoscopy up until 2 hours before the time of the colonoscopy. Instruct patients that if they experience severe bloating, distention, or abdominal pain following the first dose, delay the second dose until their symptoms resolve.
