Drug & supplement interaction

Jequirity + Entecavir

Entecavir brand name: Baraclude.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Jequirity and Entecavir 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 Entecavir 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

Jequirity and Entecavir

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 Entecavir and Jequirity 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 Entecavir

Interactions in our licensed database are recorded against drug classes, not just single drug names. Entecavir is filed under a single classification — oral drugs. Jequirity has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (minor) — and none of Entecavir’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.

What to actually watch for

No Interaction Found — But Data Suggests Jequirity and Entecavir 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. One of them is worth acting on rather than waiting out — marked below.

How to take them

Some Entecavir Products Have a Food Rule — Jequirity Should Not Break It

At least one FDA label for a product containing Entecavir says to take it on an empty stomach. Most supplements — Jequirity included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Entecavir on its own and move Jequirity to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Entecavir 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.

(2.1) 2.1 Timing of Administration BARACLUDE should be administered on an empty stomach (at least 2 hours after a meal and 2 hours before the next meal).

From the Dosage and Administration section of the FDA label we read for Entecavir — 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 Jequirity

What is Jequirity?

Jequirity
  • Asthma and cough
  • Fever
  • Sore throat and bronchitis
  • Liver complaints (hepatitis)
  • Constipation
  • Traditional infectious-disease remedies

Jequirity (Abrus precatorius) is a tropical plant whose bright red, black-tipped seeds contain abrin, one of the most toxic plant proteins known. Despite a long history in traditional medicine, the seeds are dangerously poisonous and there is no reliable evidence that it is safe or effective. It should not be used as a supplement or medicine.

Abrus precatorius · Fabaceae · Seeds, roots, and leaves · Traditional preparations (rarely used today); seeds are sometimes used in jewelry and beadwork

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

Jequirity: dosing

There is no safe or established dose of jequirity for use as a supplement or medicine. Because the seeds contain a deadly toxin, no amount is considered safe to swallow.We do not recommend taking jequirity in any form.

About Entecavir

What Is Entecavir Used For?

Brand name: Baraclude

Entecavir treats chronic hepatitis B virus (HBV) infection in adults who have signs of active virus in their blood and liver inflammation or liver damage. It is used when lab tests show persistently elevated liver enzymes (ALT or AST) or when a liver biopsy confirms active disease.

Baraclude (the brand oral solution and tablet) is also approved for children 2 years of age and older weighing at least 10 kg, with the same requirement for evidence of active viral replication and liver involvement. Generic entecavir tablets are indicated for adults; pediatric approval varies by specific product — check with your pharmacist or prescriber.

Taking Jequirity and Entecavir Together: Common Questions

Is it safe to take Jequirity with Entecavir?
We do not list a known interaction between Jequirity and Entecavir. 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 Jequirity and Entecavir have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Jequirity and Entecavir at the same time of day?
At least one FDA label for a product containing Entecavir says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Entecavir on its own and move Jequirity to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Jequirity and Entecavir combination checked?
Interactions in our licensed database are recorded against drug classes. Entecavir is filed under 1 classification, and Jequirity has documented interactions with 3 drug classes — none of Entecavir'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 Jequirity interact with any other medications?
Yes. Jequirity has 811 documented drug interactions in our database — Entecavir 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 Entecavir interact with any supplements?
Yes. Entecavir has documented interactions with 17 supplements in our database — Jequirity is not one of them. The Entecavir interaction page linked on this page lists every one, ranked by severity.
