Hi.. Dulcoease is a class C drug, in the sense its safety among pregnancy is unknown.. Constipation can be a problem during pregnancy and use of strong laxative have the potential to either induce contractions of the uterus or affect the absorption of vital nutrients.. Drink plenty of water and warm milk or coffee in the morning can help bowel movements.. Natural fibre diet is also essential and so are good exercise. You can use dulcoease stool softener sparingly during pregnancy.. All the best..
