Please do not use or consume the following medications in combination with psilocybin:
If you decide to taper off on your own accord, please make sure to always do this under supervision of a licensed medical professional.
1. Antidepressants and psilocybin
Please check with your doctor if your antidepressant is a tricyclic antidepressant, an SNRI, a SMS or Sari, NRI/NDRI, MAOI, lithium or a SSRI. We only in rare cases allow the use of SSRIs at your own risk.
A. SSRIs
SSRIs work by preventing the clearance of excess serotonin from the brain, meaning that serotonin levels are temporarily boosted. While in rare cases, it has been hypothesized that this can lead to serotonin syndrome.
There have been recent studies that have shown the opposite to be true: that SSRIs and Psilocybin can be taken together safely with no risk, but more studies need to be done to be certain of that. However, we invite all our participants to do their own research and if they feel like they would like to go ahead anyway while on the SSRI we can proceed once a waiver is signed that the participant takes the responsibility for any possible risk. We have worked with people who wanted to stay on their medicine in the past and it has worked really well, however there is still the risk mentioned above along with the risk of the substance having no effect.
Here is a link to an article about the study.
SSRI medication include:
- Citalopram (Celexa, Cipramil)
- Escitalopram (Lexapro, Cipralex)
- Fluoxetine (Prozac, Sarafem)
- Fluvoxamine (Luvox, Faverin)
- Paroxetine (Paxil, Seroxat)
- Sertraline (Zoloft, Lustral)
Here is a list of antidepressants that we do not work with in combination with Psilocybin:
b. Tricyclic antidepressants:
- Amineptine (Survector, Maneon)
- Amitriptyline (Elavil, Endep)
- Amitriptylinoxide (Amioxid, Ambivalon, Equilibrin)
- Amoxapine (Asendin)
- Clomipramine (Anafranil)
- Desipramine (Norpramin, Pertofrane)
- Dibenzepin (Noveril, Victoril)
- Dimetacrine (Istonil)
- Dosulepin (Prothiaden)
- Doxepin (Adapin, Sinequan)
- Imipramine (Tofranil)
- Lofepramine (Lomont, Gamanil)
- Maprotiline (Ludiomil)
- Melitracen (Dixeran, Melixeran, Trausabun)
- Mianserin (Tolvon)
- Mirtazapine (Remeron)
- Nitroxazepine (Sintamil)
- Nortriptyline (Pamelor, Aventyl)
- Noxiptiline (Agedal, Elronon, Nogedal)
- Opipramol (Insidon)
- Pipofezine (Azafen/Azaphen)
- Protriptyline (Vivactil)
- Setiptiline (Tecipul)
- Tianeptine (Stablon, Coaxil)
- Trimipramine (Surmontil)
Tricyclic and tetracyclic antidepressants (TCAs and TeCAs) function similarly to serotonin-norepinephrine reuptake inhibitors (SNRIs) by increasing serotonin and norepinephrine levels in the brain. However, these medications also affect many other receptors and block certain ion channels, which can lead to a broader and more dangerous range of side effects.
Given their less selective influence on the body and the known risk of heart complications, it is strongly advised not to combine TCAs or TeCAs with psilocybin. If you’re unsure, consult a healthcare professional. Psilocybin induces a powerful experience, and mixing it with any substance that influences heart function or overall physiology can be risky.
Lithium is sometimes prescribed alongside TCAs, but reports indicate that combining lithium with psychedelics can lead to severe outcomes, including fatal seizures or heart problems. For this reason, avoid mixing psilocybin with lithium.
C. SNRI medication:
- Desvenlafaxine (Pristiq, Khedezla)
- Duloxetine (Cymbalta)
- Levomilnacipran (Fetzima)
- Milnacipran (Ixel, Savella)
- Venlafaxine (Effexor XR)
SNRIs (serotonin-norepinephrine reuptake inhibitors) are known to affect serotonin and norepinephrine levels, which could lead to some interaction with psilocybin. Although there haven’t been significant reports of serious adverse reactions, SNRIs may reduce the intensity of the psychedelic experience and alter its effects.
If you have received confirmation from your doctor that it is safe to proceed, you are welcome to move forward with psilocybin use under our professional guidance. Our team will ensure that any potential risks are managed, and that you receive the necessary support to have a safe and beneficial experience.
D. MAOIs:
Monoamine oxidase inhibitors (MAOIs) are a class of drugs that are used to treat depression and anxiety. They work by blocking the enzyme monoamine oxidase, which is responsible for breaking down certain neurotransmitters in the brain. When psilocybin is taken with an MAOI, it can lead to a dangerous increase in serotonin levels, which can cause a condition known as serotonin syndrome. Symptoms of serotonin syndrome include agitation, confusion, rapid heart rate, high blood pressure, and fever. In severe cases, serotonin syndrome can lead to seizures, coma, and even death.
Common MAOI medications include:
- Bifemelane (Alnert, Celeport)
- Caroxazone (Surodil, Timostenil)
- Isocarboxazid (Marplan)
- Metralindole (Inkazan)
- Moclobemide (Aurorix, Manerix)
- Phenelzine (Nardil)
- Pirlindole (Pirazidol)
- Selegiline (Eldepryl, Zelapar, Emsam)
- Tranylcypromine (Parnate)
- Toloxatone (Humoryl)
E. NRI/NDRI
Some classic NRIs and NDRIs include:
- Bupropion (Wellbutrin)
- Methylphenidate (Ritalin, Concerta)
- Reboxetine (Edronax)
- Teniloxazine (Lucelan, Metatone)
- Viloxazine (Vivalan)
It is unknown if psilocybin and NRIs/NDRIs interact. As far as we know, psilocybin does not significantly affect the norepinephrinergic or dopaminergic neurotransmitter systems. However, to be safe, do not combine psilocybin with an NDRI.
F. SMS/SARI
Some SMS/SARI include:
- Trazodone (Desyrel)
- Vilazodone (Viibryd)
- Vortioxetine (Trintellix)
Serotonin Modulators and Stimulators (SMSs) and Serotonin Antagonists and Reuptake Inhibitors (SARIs) are two types of antidepressants that work similarly to SSRIs by increasing serotonin levels. However, they also interact with various additional serotonin receptors, either activating or deactivating them.
Because of this, these medications have more complex effects on the brain’s serotonin system, making their impact less predictable than SSRIs. To ensure safety, we advise against combining these medications with psilocybin.
G. TCAs and TeCAs
TCAs and TeCAs work in a similar way to SNRIs, by boosting the levels of serotonin and norepinephrine in the brain. However they also activate a wide range of additional receptors, and also block some ion channels, creating dangerous side effect.
Some of the most well-known TCAs and TeCAs are:
- Amineptine (Survector, Maneon)
- Amitriptyline (Elavil, Endep)
- Amitriptylinoxide (Amioxid, Ambivalon, Equilibrin)
- Amoxapine (Asendin)
- Clomipramine (Anafranil)
- Desipramine (Norpramin, Pertofrane)
- Dibenzepin (Noveril, Victoril)
- Dimetacrine (Istonil)
- Dosulepin (Prothiaden)
- Doxepin (Adapin, Sinequan)
- Imipramine (Tofranil)
- Lofepramine (Lomont, Gamanil)
- Maprotiline (Ludiomil)
- Melitracen (Dixeran, Melixeran, Trausabun)
- Mianserin (Tolvon)
- Mirtazapine (Remeron)
- Nitroxazepine (Sintamil)
- Nortriptyline (Pamelor, Aventyl)
- Noxiptiline (Agedal, Elronon, Nogedal)
- Opipramol (Insidon)
- Pipofezine (Azafen/Azaphen)
- Protriptyline (Vivactil)
- Setiptiline (Tecipul)
- Tianeptine (Stablon, Coaxil)
- Trimipramine (Surmontil)
H. Lithium
Lithium is often given as a mediator in combination with TCAs.
Numerous reports suggest that Lithium, when mixed with psychedelics, can cause fatal seizures or heart attacks. Do not mix psilocybin and Lithium.
2. Supplements that may affect serotonergic function And Psilocybin
Supplements such as 5 HTP, St John’s Wort or others should not be combined with Psilocybin.
3. Depressants And Psilocybin
Please do not consume any cannabis, alcohol or opioids for at least 72h before a Psilocybin session.
4. Stimulants And Psilocybin
Stimulants such as cocaine, amphetamines, and even caffeine can increase heart rate, blood pressure, and body temperature.
When taken with Psilocybin, they can increase the risk of cardiovascular complications, such as heart attack and stroke. In addition, stimulants can also worsen the negative effects of Psilocybin, such as anxiety and paranoia.
5. Antihistamines and psilocybin
Antihistamines such as diphenhydramine (Benadryl) and chlorpheniramine (Chlor-Trimeton) are commonly used to treat allergies and insomnia.
When taken with psilocybin, they can increase the risk of dizziness, confusion, and hallucinations.
In addition, antihistamines can also worsen the negative effects of psilocybin, such as anxiety and paranoia.
6. Other Medications:
Taking the two substances concurrently could cause harm to the liver. Even though this is a rare occurrence, it’s worth noting that antibiotics can cause damage to the liver or liver failure. On the other hand, psychotropic drugs have the potential to increase liver enzymes, which could potentially cause liver damage.
The liver plays a major role in breaking down medications in the body. A combination of both substances could trigger different adverse reactions and liver damage. This is because they are both metabolized by liver enzymes, and the combination of both substances can go beyond the capacity of the liver.
