How 4K Peg + works

Polyethylene glycol 4000 is an osmotic laxative. It retains water in the intestinal lumen, increasing stool water content and volume, which softens stools and stimulates bowel movements.

How to take 4K Peg +

Oral powder/granules: dissolve the measured dose in water (or as directed on the label) and drink. Usually taken once daily; may be taken with or without food. Ensure adequate fluid intake; use for the shortest duration needed or as prescribed.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine can cause severe loose motions, dehydration and salt imbalance. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

  • bloating
