Question 1

Can you take psilocybin mushrooms with lithium?

Accepted Answer

Documented serious harm. Do not combine. Seizures, in people with no seizure history. Also reports of unusually severe and prolonged confusional states requiring hospital admission. Not fully established. Lithium alters intracellular signalling downstream of the same 5-HT2A receptor psilocin acts on, and independently lowers the seizure threshold. The combination appears to do something neither does alone. Don't combine, this is the one real 'no' in the list. Don't stop your lithium to get around it either: it treats conditions where stopping risks a manic or depressive episode. If you want to explore psychedelics, that's a conversation with whoever manages your lithium.

Question 2

Can you take psilocybin mushrooms with maois (irreversible)?

Accepted Answer

Documented serious harm. Do not combine. A dose behaves like a much larger dose, and lasts substantially longer. Reports describe two to three times the expected intensity. Because the multiplier is not predictable, a dose someone has taken safely before can become an overwhelming one. Monoamine oxidase A is the main route by which psilocin is broken down. Inhibit it and psilocin clearance collapses, so both the peak concentration and the duration rise sharply and unpredictably. Treat as a hard no unless you are working with a prescriber who knows both drugs. Irreversible MAOIs take about two weeks to wash out after the last dose, so 'I stopped yesterday' does not clear this. Don't stop an MAOI on your own; they're usually prescribed for treatment-resistant depression, and stopping has its own risks.

Question 3

Can you take psilocybin mushrooms with tramadol?

Accepted Answer

Documented serious harm. Do not combine. Raised seizure risk. Tramadol-associated seizures are documented at ordinary therapeutic doses without any other drug involved. Tramadol lowers the seizure threshold on its own and is also a serotonin and noradrenaline reuptake inhibitor. Both properties point the same direction when combined with a serotonergic psychedelic. Avoid the combination. If you are on tramadol for pain, ask your prescriber about the interaction rather than skipping doses of a drug that may also cause withdrawal.

Question 4

Can you take psilocybin mushrooms with moclobemide and other rimas?

Accepted Answer

A real mechanism for harm exists. Stronger and longer effects than expected, to a lesser degree than with an irreversible MAOI. Same MAO-A pathway as the irreversible MAOIs, but the inhibition is competitive and reversible, so the effect is smaller and clears in a day or so rather than a fortnight. Assume any dose will hit harder than it did the last time you took it without this. Not a reason to stop your medication.

Question 5

Can you take psilocybin mushrooms with harmala alkaloids?

Accepted Answer

A real mechanism for harm exists. Substantially amplified and extended effects, plus additive nausea. The dose of the harmala is usually unmeasured, so the multiplier is unknowable. Harmine and harmaline are reversible MAO-A inhibitors. Same mechanism as moclobemide, in doses that are much harder to know because the material is a plant rather than a tablet. If you are doing this deliberately, the relevant fact is that you cannot predict the multiplier, so the only safe approach is a fraction of a dose you already know. Note that harmala MAOIs also carry the dietary tyramine problem.

Question 6

Can you take psilocybin mushrooms with bupropion?

Accepted Answer

A real mechanism for harm exists. Raised seizure risk, particularly at higher bupropion doses, in the immediate-release formulation, or where there is any additional risk factor such as an eating disorder history or alcohol withdrawal. Bupropion lowers the seizure threshold in a dose-dependent way. It has little direct serotonergic action, so the concern is seizure risk rather than serotonin toxicity. Worth genuine caution, especially at 300 mg and above. Unlike SSRIs, bupropion does not blunt psychedelic effects much, so people are more likely to take a full dose on it.

Question 7

Can you take psilocybin mushrooms with tricyclic antidepressants?

Accepted Answer

A real mechanism for harm exists. Reports of intensified effects. Additive cardiovascular strain, psilocybin already produces a modest rise in heart rate and blood pressure. Tricyclics appear to potentiate rather than blunt classical psychedelics, unlike SSRIs. They also have anticholinergic and cardiac conduction effects of their own, and clomipramine is strongly serotonergic. Expect more effect than you planned for, not less. If you have any cardiac history, the additive cardiovascular load is the part to take seriously.

Question 8

Can you take psilocybin mushrooms with st john's wort?

Accepted Answer

A real mechanism for harm exists. Unpredictable. Reported both to blunt effects and to leave them unchanged. The main documented hazard of St John's Wort is what it does to other prescribed drugs. Weakly serotonergic with some MAO inhibition in vitro, and a potent inducer of CYP3A4 and P-glycoprotein. Preparations are not standardised, so the dose of active constituent varies between products. Treat as an unknown quantity rather than as safe because it is sold in a health-food shop. If you take other medication, St John's Wort is already interacting with it.

Question 9

Can you take psilocybin mushrooms with stimulants?

Accepted Answer

A real mechanism for harm exists. Higher heart rate and blood pressure than either alone. Anxiety and panic are markedly more likely, and a panic reaction during the come-up is the most common route to a bad experience. Additive sympathomimetic load. Psilocybin raises heart rate and blood pressure modestly on its own; stimulants do so more, and both increase anxiety at the come-up. Prescribed ADHD stimulants are widely combined without disaster, but they reliably make the come-up worse. Cocaine is a different question and belongs nowhere near a psychedelic. Any pre-existing cardiac condition moves this into the do-not category.

Question 10

Can you take psilocybin mushrooms with antipsychotics?

Accepted Answer

A real mechanism for harm exists. Usually a blunted or absent experience. With typical antipsychotics, sometimes intensified dysphoria and agitation instead. Most block the 5-HT2A receptor psilocin acts on, which stops the experience. Haloperidol and other strongly dopaminergic agents are a separate case: blocking D2 without blocking 5-HT2A has been reported to make the experience worse rather than end it. If you are prescribed an antipsychotic, the underlying reason matters more than the interaction. Classical psychedelics can precipitate or worsen psychosis in vulnerable people, and that's the real thing to weigh here, not the pharmacology. Don't stop an antipsychotic to take mushrooms.

Question 11

Can you take psilocybin mushrooms with triptans?

Accepted Answer

A real mechanism for harm exists. No characteristic reported interaction. The concern is theoretical and mostly cardiovascular. Triptans are 5-HT1B/1D agonists; psilocin acts mainly at 5-HT2A but binds 5-HT1A too. Additive vasoconstriction is the theoretical concern. Low practical concern for most people, higher if you have cardiovascular disease. Worth knowing that a bad experience can produce a headache you then want to treat.

Question 12

Can you take psilocybin mushrooms with dextromethorphan?

Accepted Answer

A real mechanism for harm exists. At cough-suppressant doses, little. At recreational doses, additive serotonergic load and a confusing, disorienting combination. A serotonin reuptake inhibitor as well as a dissociative at higher doses. It is metabolised by CYP2D6, so a poor metaboliser or anyone on a CYP2D6 inhibitor reaches far higher levels than expected. A normal dose of cough medicine is not the issue. Taking DXM recreationally on top of mushrooms is a different and worse drug experience than either alone.

Question 13

Can you take psilocybin mushrooms with 5-htp and l-tryptophan?

Accepted Answer

A real mechanism for harm exists. No characteristic interaction reported with psilocybin alone. Both are precursors that raise serotonin synthesis. Psilocin does not release serotonin, so the additive risk is smaller than the supplement-shop warnings imply, but it is not zero, especially alongside an SSRI or MAOI. Common advice to take 5-HTP the day after to 'replenish serotonin' rests on a misunderstanding of how psilocybin works. It does not deplete serotonin the way MDMA is thought to. If you are on an SSRI or MAOI, do not add 5-HTP for any reason.

Question 14

Can you take psilocybin mushrooms with ssris?

Accepted Answer

Blunts or blocks the experience. A markedly blunted experience, sometimes nothing at all, from a dose that would normally work. People then redose, which is where the actual risk sits: the second dose can arrive as the first is still climbing. Chronic SSRI use downregulates 5-HT2A receptors, the receptor psilocin needs. Fewer available receptors means less effect from the same dose. This is adaptation over weeks, not a same-day interaction. Expect a weaker experience and plan for the redosing trap rather than the serotonin syndrome one. Fluoxetine is the outlier for washout: its active metabolite has a half-life of one to two weeks, so it lingers far longer than the others. Do not taper or stop an antidepressant to take mushrooms without your prescriber, discontinuation syndrome is real, and paroxetine and venlafaxine are particularly unpleasant to stop.

Question 15

Can you take psilocybin mushrooms with snris?

Accepted Answer

Blunts or blocks the experience. Blunted effects, as with SSRIs. Venlafaxine carries a little more risk than the rest of the class. Same 5-HT2A downregulation as the SSRIs, with added noradrenergic activity. Venlafaxine additionally lowers the seizure threshold at higher doses and in overdose. Same redosing trap as the SSRIs. Venlafaxine's seizure-threshold effect makes it the one in this class to be more careful with. Do not stop it abruptly, venlafaxine has one of the worst discontinuation syndromes of any antidepressant.

Question 16

Can you take psilocybin mushrooms with mirtazapine?

Accepted Answer

Blunts or blocks the experience. Blocks the experience almost entirely, more completely than an SSRI does. Taken during an experience it will substantially reduce it, along with heavy sedation. A potent direct 5-HT2A antagonist. It occupies the receptor psilocin needs, rather than merely reducing how many there are. If you are on mirtazapine, a dose will most likely be wasted. Some people keep it on hand for that reason, though a benzodiazepine is the better-understood rescue option.

Question 17

Can you take psilocybin mushrooms with trazodone?

Accepted Answer

Blunts or blocks the experience. Blunts the experience and adds heavy sedation. A 5-HT2A antagonist at the doses used for sleep, with strong sedation. Commonly prescribed for insomnia rather than depression, so people forget they are on a 5-HT2A antagonist at all.

Question 18

Can you take psilocybin mushrooms with benzodiazepines?

Accepted Answer

Blunts or blocks the experience. Reduced anxiety and intensity, drowsiness, and patchy memory of the period afterwards. This is why it is the standard rescue medication in clinical trials. GABAergic sedation dampens the anxiety and much of the perceptual intensity without touching 5-HT2A directly. It suppresses the experience rather than reversing it. The most useful thing on this page for someone having a hard time. Worth knowing about before you need it. Benzodiazepines are themselves dependence-forming and dangerous to stop abruptly after regular use, so this is an occasional rescue, not a routine pairing.

Question 19

Can you take psilocybin mushrooms with cyproheptadine?

Accepted Answer

Blunts or blocks the experience. Reduces the experience and adds sedation. It is also the drug used to treat serotonin syndrome. A first-generation antihistamine that is also a direct 5-HT2A antagonist. Occasionally suggested as a trip terminator. It's not as reliable as people claim.

Question 20

Can you take psilocybin mushrooms with cannabis?

Accepted Answer

Intensifies effects beyond what was planned for. Sharply amplified intensity, often arriving suddenly. A common route from a manageable experience to a frightening one, particularly during the come-up or peak. Not a direct receptor interaction. Cannabis independently increases anxiety and perceptual distortion in many people, and does so unpredictably in an already-altered state. If you are going to use it at all, wait for the come-down. Adding it at the peak is the specific mistake people describe regretting.

Question 21

Can you take psilocybin mushrooms with alcohol?

Accepted Answer

A real mechanism for harm exists. Increased nausea and vomiting risk, worse coordination, and a muddied experience. At higher intakes, a genuine injury risk from impaired judgement in an already-disorienting state. No specific receptor interaction. The problem is behavioural and physiological: alcohol impairs judgement and coordination, worsens nausea and dehydration, and blurs the experience. Small amounts are sometimes used to take the edge off the come-up. Meaningful drinking is a bad idea for reasons that have nothing to do with pharmacology and everything to do with falling down stairs.

Question 22

Can you take psilocybin mushrooms with lamotrigine?

Accepted Answer

No mechanism and no signal. No characteristic interaction identified. A sodium channel blocker with anticonvulsant activity. It does not act at 5-HT2A and does not lower the seizure threshold. Not the same risk category as lithium. That said, lamotrigine is usually prescribed for bipolar disorder, and a classical psychedelic can trigger mania in bipolar people, the diagnosis is the risk here, not the drug.

Question 23

Can you take psilocybin mushrooms with common non-psychiatric medication?

Accepted Answer

No mechanism and no signal. Nothing characteristic. No shared pharmacology with psilocin. Psilocin is cleared mainly by glucuronidation and MAO-A, neither of which these drugs meaningfully affect. Not a concern. If you take something not listed anywhere on this page, the honest answer is that it has not been studied, see the note below the results.
