Drug & supplement interaction

Psilocybin + Carvedilol

Carvedilol brand names: Coreg, Coreg CR.

No Known Interaction

The bottom line No known interaction

We found no known interaction between Psilocybin and Carvedilol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Carvedilol states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Psilocybin and Carvedilol

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Carvedilol and Psilocybin in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Carvedilol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Carvedilol is filed under 7 classifications — including beta-blockers, cytochrome p450 2c9 (cyp2c9) substrates, antihypertensive drugs. Psilocybin has documented interactions with 2 drug classes — the most serious being serotonergic drugs (moderate) and stimulant drugs (moderate) — and none of Carvedilol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Psilocybin and Carvedilol May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 6 of them are worth acting on rather than waiting out — marked below.

Low blood sugar Worth acting on Additional detail
Psilocybin
“Orally, psilocybin in a single dose of 315 mcg/kg resulted in increased levels of thyroid stimulating hormone, prolactin, cortisol, and adrenocorticotropic hormone. The effects of lower doses of psilocybin are unclear.

Orally, psilocybin in a single dose of 25 mg has resulted in decreased libido in a single case and transient asymptomatic hypoglycemia in 2 adult females with anorexia nervosa.”

How to take them

Some Carvedilol Products Have a Food Rule — Psilocybin Should Not Break It

At least one FDA label for a product containing Carvedilol says to take it with food. If you take Psilocybin on an empty stomach out of habit, keep them separate — and take Carvedilol with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Carvedilol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION COREG should be taken with food to slow the rate of absorption and reduce the incidence of orthostatic effects.

From the Dosage and Administration section of the FDA label we read for Carvedilol — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Psilocybin

What is Psilocybin?

Depression
Anxiety (including in serious illness)
Substance use disorders
Post-traumatic stress
Spiritual or psychological exploration

Psilocybin is a powerful psychedelic compound found in certain mushrooms and is being studied for hard-to-treat depression, anxiety, and addiction, but it is still investigational and not an approved supplement. It is illegal in most places, can cause intense and unpredictable mental effects, and should never be used outside of a supervised clinical setting.

Psilocybin is a compound found in certain mushrooms (often called 'magic mushrooms') · Dried mushrooms, capsules, isolated/synthetic psilocybin (used in clinical trials)

An interaction check asks whether these two react with each other — it does not ask whether Psilocybin is a good idea for someone in your situation. Here is what our Psilocybin record says about it on its own.

Psilocybin: dosing

There is no established, safe over-the-counter dose of psilocybin. In research studies, doses are carefully measured, purified, and given under medical supervision with psychological support before, during, and after.Mushroom strength varies widely, so there is no reliable way to know how much you are taking from wild or non-medical sources. Because psilocybin is illegal in most places and can cause strong reactions, we cannot recommend any home dose.

About Carvedilol

What Is Carvedilol Used For?

Brand names: Coreg, Coreg CR

Carvedilol is used to treat three main conditions: mild-to-severe chronic heart failure, high blood pressure (hypertension), and reduced heart pumping function (left ventricular dysfunction) in people who have survived a heart attack. For heart failure, it is usually prescribed alongside other medications such as diuretics, ACE inhibitors, and digitalis to help people live longer and reduce the chance of hospital stays.

For people who have had a heart attack and whose heart is not pumping as well as it should, carvedilol is used to lower the risk of dying from heart-related causes. For high blood pressure, it can be used on its own or combined with other blood pressure medicines.

Most-Reported Side Effects for Carvedilol

Carvedilol Is Linked to Lower Levels of One Nutrient

Natural Medicines records Carvedilol as a medicine that can lower these. This is not an interaction with Psilocybin — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:

Taking Psilocybin and Carvedilol Together: Common Questions

Is it safe to take Psilocybin with Carvedilol?

We do not list a known interaction between Psilocybin and Carvedilol. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.

Do Psilocybin and Carvedilol have any of the same side effects?

Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

Should I take Psilocybin and Carvedilol at the same time of day?

At least one FDA label for a product containing Carvedilol says to take it with food. If you take Psilocybin on an empty stomach out of habit, keep them separate and take Carvedilol with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Carvedilol products can differ — so check the directions on your own box. This is about absorption, not an interaction.

How was the Psilocybin and Carvedilol combination checked?

Interactions in our licensed database are recorded against drug classes. Carvedilol is filed under 7 classifications, and Psilocybin has documented interactions with 2 drug classes — none of Carvedilol's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.

Does Psilocybin interact with any other medications?

Yes. Psilocybin has 293 documented drug interactions in our database — Carvedilol is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.

Does Carvedilol interact with any supplements?

Yes. Carvedilol has documented interactions with 211 supplements in our database — Psilocybin is not one of them. The Carvedilol interaction page linked on this page lists every one, ranked by severity.
