Polyethylene Glycol (Movicol / Forlax) Sachet Uses (Fayde / Kis kaam aata hai)
Polyethylene Glycol (PEG / Macrogol) is an Osmotic Laxative available OTC in Pakistan. Below are all approved and common uses.
Primary Uses (Mukhya Istemal)
Constipation (Qabz)
Constipation — reduced bowel movement (less than 3 times per week), hard stool, straining, incomplete feeling. PEG osmotically retains water in the gut — stool becomes soft, moist and loose — bowel movement is stimulated. After dietary fibre (ispaghol) and hydration, PEG is the first-line pharmacological choice for chronic and acute constipation.
Key advantages over other laxatives:
- Not fermented → less gas/bloating than lactulose
- Not absorbed → electrolyte disturbances rare at standard doses
- Safe long-term use
- Safe in elderly, renal impairment, and pregnancy
IBS-C (Constipation-predominant IBS)
Improves stool consistency and regularises bowel frequency in IBS-C.
Faecal Impaction
Higher doses (multiple sachets) loosen impacted stool in severe impacted constipation.
Who Should Take It (Kin logon ke liye)
- Adults with constipation — especially chronic cases
- Elderly patients — gentle, predictable action
- Patients on constipating medications (opioids, iron, calcium channel blockers)
- IBS-C patients
- Constipation in pregnancy (confirm with doctor)
- Renal impairment patients
When NOT to Use (Kab nahi lena chahiye)
- Bowel obstruction or suspected obstruction — CONTRAINDICATED
- Bowel perforation or risk of perforation
- Toxic megacolon
- Severe abdominal pain with vomiting
Summary
