Where it stands

Rapid Summary

Overview

Macrogol 3350 (PEG) WITHOUT added electrolytes. Acts exactly like Movicol, but is completely tasteless and can be mixed into any hot or cold drink.

Clinical Focus

Provides the same excellent laxative effect as Movicol, massively improving patient compliance because it doesn't taste like salty lemon water.

Bottom Line

Osmolax is an unflavoured macrogol osmotic laxative for constipation, but provides no electrolyte replacement unlike Movicol and requires adequate fluid intake.

Quick reference

Class & Role

Osmotic Laxative — Macrogol 3350 (PEG) WITHOUT added electrolytes.

Route / Formulation

Tasteless, odorless white powder (Macrogol 3350 pure). (OsmoLax)

Usual Dose & Max

PO 1-2 scoops (17-34g) OD. Mix with 200 mL of any hot/cold liquid (water, juice, coffee). Max 3-4 scoops/day (Adults).

Key Indication Doses

Constipation (Adults): PO 1-2 scoops (17-34g) OD. Mix with 200 mL of any hot/cold liquid (water, juice, coffee). Constipation (Paediatrics): Strictly weight-based (e.g., 1 scoop daily for children > 2 years).

Best Uses

Osmolax is an unflavoured macrogol osmotic laxative for constipation, but provides no electrolyte replacement unlike Movicol and requires adequate fluid intake.

Key Risks

Gastrointestinal: Bloating, flatulence, nausea. Metabolic: Because it lacks the protective electrolytes of Movicol, massive doses *could* theoretically cause minor electrolyte shifts, but this is clinically rare at standard doses.

Key Interactions

May reduce transit time of other drugs.

Monitoring

Monitor bowel actions and fluid tolerance. Each level scoop is mixed with about 240 mL water; use caution with fluid restriction, dysphagia, or thickened-fluid requirements.

Clinical Pearl

For dementia patients who spit out Movicol, stirring a scoop of Osmolax into their morning cup of tea is completely undetectable and guarantees they get their laxative.
