Anticholinergic antispasmodic (IBS, GI motility)Reviewed May 19, 2026

Dicyclomine (Bentyl) and Ketamine Therapy | Tovani Health

Bentyl (Dicyclomine)Anticholinergic antispasmodic (IBS, GI motility)

Verdict at Tovani Health

Fully compatible; dicyclomine's anticholinergic effects are intrinsic, not a stacking concern with ketamine.

Dicyclomine and ketamine have no clinically significant interaction. Dicyclomine has well-known anticholinergic side effects (dry mouth, urinary retention, cognitive effects, falls in elderly), but those are intrinsic to dicyclomine and not amplified by ketamine. Ketamine itself does not have meaningful clinical anticholinergic activity (it actually causes hypersalivation, the opposite). Continue as prescribed for IBS or GI motility.

If you take Bentyl 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 Bentyl interacts with ketamine

Dicyclomine antagonizes muscarinic acetylcholine receptors, reducing GI smooth muscle spasm. Independent anticholinergic side-effect profile. No meaningful ketamine PK interaction.

What we do at intake

Continue as prescribed. Tell us about any anticholinergic side effects so we can advise on hydration and orthostasis after sessions.

Bottom line

Dicyclomine and ketamine have no clinically significant interaction. Dicyclomine has well-known anticholinergic side effects (dry mouth, urinary retention, cognitive effects, falls in elderly), but those are intrinsic to dicyclomine and not amplified by ketamine. Ketamine itself does not have meaningful clinical anticholinergic activity (it actually causes hypersalivation, the opposite). Continue as prescribed for IBS or GI motility.
