Interactors with a reference entry

Cardiovascular

  • Psilocybin and Propranolol Monitor Only

    Theoretical: beta blockade may blunt heart rate and somatic anxiety during psilocybin sessions. Propranolol contraindications (asthma, bradycardia, AV block) must be screened. No direct psilocybin-propranolol studies found.

    Evidence: FDA label (Inderal) + mechanistic

GLP-1/GIP Agonist

  • Psilocybin and Zepbound (tirzepatide) Clinician Review

    Demonstrated delayed gastric emptying with potential impact on oral psilocybin absorption. Delayed or variable onset increases risk of premature non-response conclusion and dose stacking. Nausea overlap may worsen tolerability.

    Evidence: FDA label (Zepbound 2025) + mechanistic

MAOI

Mood Stabilizer

Opioid

  • Psilocybin and Oxycodone (Percocet) Monitor Only

    No established contraindication. No direct pharmacodynamic overlap. Acute pain may alter subjective setting.

    Evidence: Observational

SSRI/SNRI
