Docusate (Colace) and Ketamine Therapy | Tovani Health
Colace (Docusate) (also: Surfak) — Stool softener (mild laxative)
Verdict at Tovani Health
Fully compatible with KAP.
Docusate and ketamine have no clinically significant interaction. Mild stool softener used for opioid-induced or pregnancy constipation; works by reducing surface tension and allowing water into stool. The clinical efficacy is modest — most large reviews show docusate is barely better than placebo for actual constipation — but it remains widely used and is genuinely safe.
If you take Colace 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.
