Anticholinergic transdermal patch (motion sickness, post-op nausea)Reviewed May 22, 2026

Scopolamine Patch (Transderm Scop) and Ketamine Therapy | Tovani Health

Transderm Scop (Scopolamine) (also: Hyoscine)Anticholinergic transdermal patch (motion sickness, post-op nausea)

Verdict at Tovani Health

Fully compatible; anticholinergic effects are intrinsic, not a ketamine stack.

Scopolamine and ketamine have no clinically significant interaction. The 72-hour transdermal patch is common for cruise motion sickness and post-op nausea prevention. Anticholinergic effects (dry mouth, drowsiness, blurred vision, urinary retention in older adults) are intrinsic to scopolamine; ketamine doesn't have meaningful clinical anticholinergic activity (it actually causes hypersalivation).

If you take Transderm Scop 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 Transderm Scop interacts with ketamine

Scopolamine antagonizes muscarinic acetylcholine receptors with broad CNS penetration. Steady transdermal delivery over 72 hours. No CYP interaction with ketamine.

What we do at intake

Continue as needed for travel or post-op. Disclose patch placement date.
