Drug & supplement interaction

Eleuthero + Crofelemer

Crofelemer brand names: Fulyzaq, Mytesi.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Eleuthero and Crofelemer 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 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.

Eleuthero and Crofelemer

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 Crofelemer and Eleuthero 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.

Eleuthero safety at a glance

Eleuthero overall Use caution Often well tolerated for short-term use, but evidence on long-term safety is limited.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety data, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Crofelemer

Interactions in our licensed database are recorded against drug classes, not just single drug names. Crofelemer is filed under a single classification — oral drugs. Eleuthero has documented interactions with 10 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Crofelemer’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.

No Interaction Found — But Data Suggests Eleuthero and Crofelemer May Share a Side Effect

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.

  • Nausea Additional detail

    Crofelemer

    Listed in the ADVERSE REACTIONS section of the FDA label for Crofelemer. Read the label on DailyMed ›

Reported for Eleuthero but not commonly for Crofelemer: raised blood pressure, stomach upset, mood changes or irritability and anxiety or restlessness.

Effects for Crofelemer come from the ADVERSE REACTIONS section of its FDA label; effects for Eleuthero come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 233 voluntary FDA FAERS reports for Crofelemer that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Eleuthero

What is Eleuthero?

Eleuthero
  • Fatigue and low energy
  • Physical and athletic performance
  • Stress resistance (adaptogen)
  • Immune support
  • Mental focus and alertness

Eleuthero is an herb traditionally used as an 'adaptogen' to fight fatigue, boost energy, and help the body handle stress. The scientific evidence behind these uses is limited and mixed, so it should not replace proven treatments. It is generally well tolerated short-term, but pregnant and breastfeeding people and those with certain conditions should avoid it or check with a healthcare provider first.

Eleutherococcus senticosus · Araliaceae · Root and rhizome (sometimes the stem bark) · Capsules, tablets, dried root powder, liquid extracts (tinctures), and teas

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

Eleuthero: dosing

There is no official standardized dose for eleuthero, and products differ widely in strength and form (dried root, extracts, tinctures, and teas).The best approach is to follow the directions on the product label and not exceed the recommended amount.

About Crofelemer

What Is Crofelemer Used For?

Brand names: Fulyzaq, Mytesi

Mytesi (crofelemer) is used to provide symptomatic relief of non-infectious diarrhea in adult patients with HIV/AIDS who are taking antiretroviral therapy. It is not a treatment for the underlying HIV infection itself — it specifically targets the diarrhea that can accompany antiretroviral treatment.

It is important to note that Mytesi is not intended for diarrhea caused by an infection (such as bacteria or a virus). A prescriber will rule out infectious causes before starting this medication.

Most-Reported Side Effects for Crofelemer

From FAERS, the FDA’s public side-effect reporting system (233 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 26 reports
Anxiety 14 reports
Emotional distress 14 reports
Anhedonia 12 reports
Fatigue 11 reports

Taking Eleuthero and Crofelemer Together: Common Questions

Is it safe to take Eleuthero with Crofelemer?
We do not list a known interaction between Eleuthero and Crofelemer. 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 Eleuthero and Crofelemer have any of the same side effects?
Yes — our sources link each of them separately to one 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.
How was the Eleuthero and Crofelemer combination checked?
Interactions in our licensed database are recorded against drug classes. Crofelemer is filed under 1 classification, and Eleuthero has documented interactions with 10 drug classes — none of Crofelemer'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 Eleuthero interact with any other medications?
Yes. Eleuthero has 1,140 documented drug interactions in our database — Crofelemer 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 Crofelemer interact with any supplements?
Yes. Crofelemer has documented interactions with 17 supplements in our database — Eleuthero is not one of them. The Crofelemer interaction page linked on this page lists every one, ranked by severity.
