thank you for your query.Miralax
is polyethylene glycol
This medication is used to treat occasional constipation. It works by holding water in the stool to soften the stool and increases the number of bowel movements. It is known as an osmotic-type laxative.
Extended use or overuse may result in dependence on laxatives and chronic constipation
. Overuse may cause diarrhea
, excess loss of body water (dehydration
), and mineral imbalance (e.g., low sodium).
hence i would advise him to stop miralax as it would worsen the IBS.
and rather take fiber containing laxatives.
these will help with his IBS symptoms too.
wishing you good health
