My GI told me to use Miralax at night, and Colace (same medicine as Dulcalax) twice a day, PLUS a fiber, like Metamucil.
After years of using Dulcalax, though, I've developed an intolerance to it. Now, it makes me throw up. I don't know what I can use instead, because the pharmacist said that the medicine in Dulcalax, Docusate Sodium, is the only stool softener on the market. I've been trying to use chlorella (a type of algae), which has some affect as a stool softener.
