Lily-of-the-valley and Danthron , Docusate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

STIMULANT LAXATIVES

Why this applies to Danthron , Docusate

Danthron , Docusate falls under STIMULANT LAXATIVES — the group Lily-of-the-valley interacts with.

Theoretically, using lily-of-the-valley with stimulant laxatives can increase the risk of cardiac glycoside toxicity.
Lily-of-the-valley contains cardiac glycosides. The overuse of stimulant laxatives can increase the risk of cardiac glycoside toxicity with lily-of-the-valley due to potassium depletion.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the connection most people miss with Co-Danthrusate (the danthron and docusate combo): it's a stimulant laxative, and using it too much or too often can flush potassium out of your body. Low potassium is the real troublemaker here. Lily-of-the-valley contains natural heart-affecting compounds (cardiac glycosides) that work a lot like the heart drug digoxin, and when your potassium runs low, those compounds hit your heart harder than they should.

That combo could raise the risk of toxic effects on the heart, things like a slow, fast, or irregular heartbeat, nausea, or feeling dizzy. To be fair, this is a theoretical concern based on how these things work, not a stack of case reports. Honestly, lily-of-the-valley isn't safe to take on its own anyway. Please check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Danthron , Docusate page

“Co-Danthrusate pairs danthron, a stimulant laxative, with docusate, a stool softener, and that stimulant action is exactly why its list of 46 interacting supplements deserves genuine care. Twenty-nine of the entries are herbal laxatives that pile the same effect on top and can drain fluid and potassium fast.”
