4.1. Therapeutic indications

This medicine is indicated for cleansing of the bowel when required as a preparation for certain diagnostic procedures such as colonoscopy.

Coloprep is indicated in adults over 18 years of age.

4.2. Posology and method of administration

Posology

Adults (over 18 years of age)

The usual adult dosage of this medicine is 32 tablets. The total dose of phosphate is 32.79 g.

The intake of this medicine should begin the day before the colonoscopy. The day before the colonoscopy, patients may have a light, low-fibre breakfast (coffee or tea with or without sugar, toast, butter or equivalent, fruit jelly or honey). After noon, taking only “clear liquids” is permitted. “Clear liquid” may be water, light soup, diluted fruit juice without pulp, weak tea or black coffee, light soda with or without bicarbonate.

Recommended administration regimen

The evening before the colonoscopy procedure:

  • Take 4 tablets with 250 ml of water (or another clear liquid)
  • Then repeat 4 times in the same conditions, every 15 minutes, for a total of 20 tablets to swallow.

The day of the colonoscopy procedure, (starting 3-5 hours before the procedure):

  • Take 4 tablets with 250 ml of water (or another clear liquid)
  • Then repeat 2 times in the same conditions, every 15 minutes for a total of 12 tablets to swallow.

Alternative administration regimen in case of morning colonoscopy

For early morning colonoscopy, it is possible to adapt the dosing schedule by taking all the tablets in the evening before the procedure, and with an interval of at least 4 hours between the beginning of the intake of the first 20 tablets (to be absorbed at the rate of 4 tablets with 250ml of water or another clear liquid every 15 minutes) and the intake of the last 12 tablets (to be absorbed at the rate of 4 tablets with 250ml of water or another clear liquid every 15 minutes).

Patients should be advised of the importance of following the recommended fluid regimen and of drinking as much liquid as possible to replace lost fluids by increased intestinal peristalsis. Drinking large amounts of clear liquid also helps ensure the cleanliness of the colon during colonoscopy. See Section 4.4 Special warnings and precautions for use.

Patients should not repeat this dosage for at least seven days. No additional laxatives are necessary when taking this medicine, particularly those agents containing sodium phosphate

Elderly

In the elderly, the dosage is identical to that of adults. It may be useful to assess renal function before use in the elderly. This product is contraindicated in patients over 75 years of age (See section 4.3).

Method of administration

Adults (over 18 years of age)

Each intake of 4 tablets must be done with 250 ml of water or another clear liquid.

No solid food should be taken from the start of the course of treatment until after the clinical procedure.
