Can I take valium, synthroid, (thyroxine) and percocet with Dulcolax sensitive stomache for women for constipation? I am afraid to mix and I only this laxative available and I have not defecated pain medication.

Yes: However, am concerned about combination of valium and percocet. Both are sedating and can mix in a deadly cocktail. Very worrisome.
