Clinical data and state rules are separate facts. Both are shown; neither is a decision.

01 Interaction with psilocybin

Blunting plus added BP rise; low serotonin syndrome risk.

Human data with psilocybin: Case reports or surveys only
Common practice: Most clinical trials required discontinuation beforehand (Tap 2025); one trial gave psilocybin alongside a continued SSRI (Goodwin 2023). Whether to change the medication is the prescriber's decision.

Withdrawal or rebound if stopped abruptly: Stopping suddenly can cause withdrawal or a rebound of symptoms. Any change to the dose is the prescriber’s decision. Sources [1]
Raises blood pressure or heart rate: Raises blood pressure or heart rate. Psilocybin raises both for several hours, so the effects can add. Sources [1]
Serotonergic: Increases serotonin activity, for example by blocking its reuptake or releasing it. Psilocybin acts on serotonin receptors, so effects can add together. With antidepressant use, the psilocybin response can be weaker. Sources [1]
