How can you use it for 4 weeks to heal anal fissure if instruction on cloace stool softener box says don't use more that a week to minimize dependency?

Very safe drug: Those instructions on the box are intended for non- physicians and provide legal coverage the drug manufacturer. Colace (docusate sodium) is a very safe non-absorbed drug that can be used chronically if medically necessary. If your doctor has told you to use the medication for 4 weeks, then i recommend doing so.

OK TO USE 4 WEEKS: Safe to use longer than box says;you may need to use nitrogylcerin ointment in special dose form for anal fissure.
