Good to know
- Dulcolax is a brand on two different drugs: Dulcolax Stool Softener is docusate sodium 100 mg (this group), while Dulcolax Laxative tablets are bisacodyl, a stimulant laxative.
- Stool softener "plus stimulant" products add sennosides (senna) to docusate — a different combination, not in this group.
- Colace capsules and store-brand softgels list the same 100 mg of docusate sodium; the form differs, not the dose.
