Eurycoma Longifolia + Avibactam Sodium, Ceftazidime

Avibactam Sodium, Ceftazidime brand name: Avycaz.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Eurycoma Longifolia and Avibactam Sodium, Ceftazidime 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.

Interaction report

Eurycoma Longifolia and Avibactam Sodium, Ceftazidime

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 Avibactam Sodium, Ceftazidime and Eurycoma Longifolia 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.

Eurycoma Longifolia safety at a glance

Eurycoma Longifoli... overall Use caution Generally tolerated short-term in studies, but long-term safety and product quality are uncertain.
Pregnancy Avoid Not enough safety data and possible hormonal effects, so avoid during pregnancy.
Breastfeeding Avoid No reliable safety information, so it is best to avoid while breastfeeding.

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

Pharmacist analysis

Although there is no known interaction in this case, Eurycoma longifolia, most commonly known as Tongkat Ali, does have some potential interactions that are important to be aware of.

For example, it may interact with the following:

  • CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
  • CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES
  • CYTOCHROME P450 2A6 (CYP2A6) SUBSTRATES
  • Propranolol
  • Testosterone

Tongkat Ali has been reported to inhibit certain metabolizing enzymes in the liver (the ones mentioned above) and therefore, may increase the levels of substances metabolized by those enzymes. This could potentially affect the way these substances work or how long they stay in your system.

In regard to propranolol, some studies show that Tongkat Ali decreases how well propranolol is absorbed in the gut and could reduce its effects. It is not known if separating administration will prevent this interaction/

Lastly, testosterone, Tongkat Ali may theoretically further increase levels of testosterone, a hormone responsible for various functions in the body. You should be cautious combining the two.

How we checked

Why No Interaction Is Listed for Avibactam Sodium, Ceftazidime

Interactions in our licensed database are recorded against drug classes, not just single drug names. Avibactam Sodium, Ceftazidime is filed under 4 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Eurycoma Longifolia has documented interactions with 5 drug classes — the most serious being propranolol (inderal) (moderate), cytochrome p450 1a2 (cyp1a2) substrates (minor) and cytochrome p450 2a6 (cyp2a6) substrates (minor) — and none of Avibactam Sodium, Ceftazidime’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 Eurycoma Longifolia and Avibactam Sodium, Ceftazidime 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. One of them is worth acting on rather than waiting out — marked below.

    Eurycoma Longifolia

    “Some research in both humans and animals suggests that Eurycoma longifolia might increase testosterone levels. If testosterone levels are increased beyond the normal range, there is risk of testosterone-related side effects which could include acne, insulin resistance, hepatotoxicity, and others.”

What is Eurycoma Longifolia?

Eurycoma Longifolia

  • Athletic performance and muscle strength

Eurycoma longifolia (tongkat ali) is a Southeast Asian herb most popular for supporting testosterone, libido, and male fertility, with some small human studies suggesting possible benefits.

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

Eurycoma Longifolia: dosing

About Ceftazidime and Avibactam Injection

What Is Ceftazidime and Avibactam Injection Used For?

Brand name: Avycaz

Avycaz (ceftazidime and avibactam) is used to treat three types of serious bacterial infections in adults and children at least 31 weeks gestational age: complicated intra-abdominal infections (cIAI), complicated urinary tract infections (cUTI) including pyelonephritis (a kidney infection), and hospital-acquired bacterial pneumonia or ventilator-associated bacterial pneumonia (HABP/VABP). All three of these infections must be caused by specific susceptible gram-negative bacteria for Avycaz to be effective.

When treating complicated intra-abdominal infections, Avycaz must be used together with metronidazole, another antibiotic. Avycaz is only meant for infections proven or strongly suspected to be caused by bacteria that it can actually fight — using it otherwise can lead to antibiotic resistance.
