Bisacodyl (Dulcolax) and Ketamine Therapy | Tovani Health
Dulcolax (Bisacodyl) (also: Correctol, Bisac-Evac) — Stimulant laxative (constipation, bowel prep)
Verdict at Tovani Health
Fully compatible with KAP.
Bisacodyl and ketamine have no clinically significant interaction. Stimulant laxative available as oral tablets (delayed-release, target colon) and rectal suppositories (faster acting). Same framework as senna — cramping with overuse, electrolyte shifts with chronic high-dose use. The 'don't crush oral bisacodyl' rule (the enteric coating exists to bypass the stomach) is intrinsic.
If you take Dulcolax regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.
How Dulcolax interacts with ketamine
Bisacodyl is hydrolyzed in the colon to its active form, which stimulates colonic peristalsis and reduces water absorption. Minimal systemic absorption. No CYP interaction with ketamine.
What we do at intake
Take as needed. Don't crush or chew oral tablets.
