Aloe and Casanthranol, Docusate Sodium

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

Moderate

STIMULANT LAXATIVES

Why this applies to Casanthranol, Docusate Sodium

Casanthranol, Docusate Sodium falls under STIMULANT LAXATIVES — the group Aloe interacts with.

Theoretically, aloe latex might increase the risk for fluid and electrolyte loss when taken with stimulant laxatives.
Due to cathartic laxative effects of aloe latex, concomitant use with other stimulant laxatives might compound fluid and electrolyte loss.
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 simple version: Peri-Colace already contains casanthranol, which is a stimulant laxative, plus docusate, a stool softener. The yellow latex part of aloe (taken by mouth) is itself a strong stimulant laxative. So you'd essentially be stacking two laxatives that work the same way. The worry isn't that one breaks down the other; it's that their effects add up.

When that happens, you can lose too much water and key minerals like potassium. That can show up as cramping, watery diarrhea, dizziness, weakness, or muscle issues. To be fair, this is a theoretical concern based on how these work, not strong proof, but it's a sensible one. Aloe gel on your skin is not the issue here, only oral aloe latex. Please check with your pharmacist or doctor before combining them.

About Aloe

What is Aloe?

Aloe
  • Minor burns and skin irritation
  • Wound healing
  • Constipation
  • Skin hydration and moisturizing
  • Digestive complaints
  • Hair and scalp care

Aloe vera gel is widely used on the skin for minor burns and irritation, and some research suggests it may help. Aloe latex (the yellow part) is a strong laxative that can cause cramping and is not considered safe for regular use. Talk to your pharmacist or doctor before taking aloe by mouth, and avoid oral aloe during pregnancy.
