Question 1

Who should not use psilocybin?

Accepted Answer

Psilocybin is contraindicated for individuals with a personal or family history of schizophrenia, bipolar disorder with psychotic features, or other psychotic disorders, as it may trigger or worsen psychotic episodes. It should be avoided by those on lithium (seizure risk), MAO inhibitors, or high-dose SSRIs. Pregnant or nursing individuals should avoid psilocybin. Those with serious cardiovascular conditions should consult a physician first.

Question 2

Can you take psilocybin with antidepressants?

Accepted Answer

SSRIs and SNRIs may significantly reduce or eliminate psilocybin's effects because they compete for the same 5-HT2A serotonin receptors. Some people taper off antidepressants before a psilocybin session, but this should only be done under medical supervision — abrupt discontinuation can be dangerous. Combining psilocybin with MAO inhibitors can produce dangerously intense effects (serotonin toxicity risk). Always consult a healthcare provider about medication interactions.

Question 3

What drug combinations should be avoided with psilocybin?

Accepted Answer

Dangerous or significant interactions with psilocybin include: lithium (seizure risk — avoid completely); MAO inhibitors (dangerous potentiation — avoid completely); tramadol (serotonin syndrome risk); stimulants like amphetamines (cardiovascular strain); alcohol (unpredictable interactions, generally discouraged); cannabis (can intensify anxiety, especially at peak). SSRIs may block effects without additional safety risk, but consult a doctor before any medication change.
