Using polyethylene glycol in preference to lactulose is likely to improve the quality of patient care by reducing the use of a less effective treatment.
Course of treatment for chronic constipation not normally > 2 weeks.
A stimulant laxative should be added if disimpaction is not achieved after 2 weeks.
Efficacy requires adequate fluid intake. Contains Na+, care in patients with hypertension / heart failure. Laxido® replaces Movicol® as lower cost brand equivalent.
