OsmoLax Clinical Evidence
Good Evidence
Macrogol laxatives are clinically proven – with the greatest amount of clinical evidence amongst OTC laxatives.3
ADULTS: A first step for adults with constipation
Macrogol with or without electrolytes are clinically proven and are the most effective laxatives amongst the osmotic laxatives1,3
Network meta-analysis confirms that the addition of electrolytes to macrogols does not provide any additional clinical benefits in the relief of constipation in adults1
The use of macrogol laxatives in adults is considered a first step after bulking-forming agents (e.g. psyllium).
CHILDREN: First-line in children with constipation
Macrogol with or without electrolytes are clinically proven and are more effective than lactulose3,4
Network meta-analysis confirms that the addition of electrolytes to macrogols does not provide any additional clinical benefits in the relief of constipation in children2
Macrogol laxatives are considered first line in children if simple lifestyle measures don’t help.
OsmoLax – the benefit of no added electrolytes
Macrogol without added electrolytes is easy to give because it is a virtually tasteless and odourless powder that can be mixed in the person’s drink of choice1,4
Macrogol without electrolytes has better palatability and this may influence patient compliance1,2,4
