Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
4K Peg + contains Polyethylene Glycol 4000 (Macrogol 4000) (strength unknown). It belongs to the Osmotic laxative (polyethylene glycol/macrogol) class of medicines.
Constipation (including chronic constipation); softening of stools and relief of difficult/painful bowel movements.
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.
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.
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.
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.
Most side effects of 4K Peg + are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Do not use in suspected/known intestinal obstruction, perforation, severe inflammatory bowel disease, severe dehydration, or unexplained abdominal pain without medical advice. Stop and consult a doctor if severe diarrhoea, abdominal distension, rectal bleeding, or no improvement occurs. Prolonged use may cause electrolyte imbalance, especially in elderly or those on diuretics. Use with caution in renal impairment and in patients prone to fluid/electrolyte disturbances.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for anyone with a suspected bowel obstruction, or with severe abdominal pain of unknown cause.
May reduce absorption of other oral medicines if taken at the same time; keep a 2-hour gap from other oral drugs. Caution with diuretics, corticosteroids, or medicines affecting electrolytes (risk of imbalance if diarrhoea occurs).
Store in a cool, dry place at room temperature. Protect from moisture and direct light. Keep container tightly closed and out of reach of children.
Increase fibre, fluids and physical activity — these treat the cause rather than the episode. Do not ignore the urge to go; a regular routine helps.
