Effects

Pregnancy
Can be used in pregnancy when needed, usually after non-drug measures fail; severe diarrhoea or vomiting can affect hydration and pill absorption.
Mother
May cause diarrhoea, nausea, vomiting, bloating, and dehydration if too much is taken.
Baby
Very little is expected to reach the baby because macrogol is not absorbed much; official data in pregnancy are limited.

Trimester Notes

1st Trimester
Can be used if needed, but try non-drug measures first. Limited pregnancy data mean provider review is best.
2nd Trimester
Can be used if needed. Watch for diarrhoea, vomiting, and dehydration.
3rd Trimester
Constipation is common late in pregnancy. Use only if diet and fluids do not help, and follow prescriber advice.
