Cereus + Docusate Sodium, Phenolphthalein
Docusate Sodium, Phenolphthalein brand names: Correctol, Modane Plus.
We found no known interaction between Cereus and Docusate Sodium, Phenolphthalein in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Cereus and Docusate Sodium, Phenolphthalein
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Docusate Sodium, Phenolphthalein and Cereus in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Cereus safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Docusate Sodium, Phenolphthalein
Interactions in our licensed database are recorded against drug classes, not just single drug names. Docusate Sodium, Phenolphthalein is filed under 2 classifications — stimulant laxatives, oral drugs. Cereus has documented interactions with 2 drug classes — the most serious being digoxin (lanoxin) (moderate) and monoamine oxidase inhibitors (maois) (moderate) — and none of Docusate Sodium, Phenolphthalein’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Docusate Sodium, Phenolphthalein page
“Correctol and Modane Plus pair docusate, a stool softener, with phenolphthalein, a stimulant laxative, and the pairings below deserve real caution. Of the 46 supplements and herbs on this list, 29 are plant laxatives that work the same way phenolphthalein does, so doubling up can drain fluid and potassium fast.”

About Cereus
What is Cereus?
- Heart palpitations
- Mild heart symptoms
- Anxiety and nervous tension
- Shortness of breath
- Fluid retention
Cereus (often called night-blooming cereus) is a cactus traditionally used in folk and homeopathic medicine for heart-related complaints like palpitations. High-quality human evidence supporting these uses is lacking, and because it may affect the heart, it should be used only under medical guidance. Pregnant and breastfeeding people should avoid it.
Selenicereus grandiflorus · Cactaceae · Flowers and young stems · Tincture, liquid extract, capsules, homeopathic preparations
An interaction check asks whether these two react with each other — it does not ask whether Cereus is a good idea for someone in your situation. Here is what our Cereus record says about it on its own.
Cereus: dosing
There is no established standard dose of Cereus. Products vary widely in strength, and homeopathic preparations are very different from herbal tinctures.If you choose to use a Cereus product, follow the directions on the label and do not exceed them.
