No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Evodia and Dicloxacillin Sodium 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 Dicloxacillin Sodium states a food rule worth keeping to.

Evodia and Dicloxacillin Sodium

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 Dicloxacillin Sodium and Evodia 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 Dicloxacillin Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dicloxacillin Sodium is filed under 5 classifications — including penicillin, antibiotic drugs, nephrotoxic drugs. Evodia has documented interactions with 11 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), caffeine (moderate) and chlorzoxazone (parafon forte, paraflex) (moderate) — and none of Dicloxacillin Sodium’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

What Evodia Itself Has Been Linked To

This is not an interaction — nothing below involves Dicloxacillin Sodium. It is the side-effect record for Evodia on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Evodia, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

    “There is no reliable evidence regarding the safety of evodia from clinical trials. In animal studies, evodia has induced QT prolongation and Torsade de pointes.”

    “In animal studies, evodia acts as a proarrhythmic agent with a dose-dependent effect. Evodia infusion has resulted in QT prolongation and Torsade de pointes. It is not clear what dose of evodia, if any, is required to produce a similar effect in humans.”

Everything above comes from the Natural Medicines adverse-effect record for Evodia — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Dicloxacillin Sodium’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Dicloxacillin Sodium column appears here.

How to take them

Some Dicloxacillin Sodium Products Have a Food Rule — Evodia Should Not Break It

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

Patients weighing less than 40 kg (88 lbs) DRUG ADULTS CHILDREN Mild to Moderate Severe Mild to Moderate Severe Dicloxacillin 125 mg every 6 hours 250 mg every 6 hours 12.5 mg/kg/day 1 in equally divided doses every 6 hours 25 mg/kg/day 1 in equally divided doses every 6 hours Dicloxacillin is best absorbed when taken on an empty stomach, and should be administered at least 1 hour before or 2 hour

From the Dosage and Administration section of the FDA label we read for Dicloxacillin Sodium — where that label names a specific product, the instruction is that product's. See the Dicloxacillin Sodium drug page ›

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.

Everything else you take

See Every Supplement That Interacts With Dicloxacillin Sodium

This page covers Evodia only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dicloxacillin Sodium page lists 56 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), Aristolochia (moderate) and Bacillus Coagulans (moderate).

By severity: 3 major · 42 moderate · 11 minor.

From our pharmacist’s overview on the Dicloxacillin Sodium page

“The riskiest pairing on this page is Siberian cocklebur with dicloxacillin (Dynapen), an antibiotic for staph skin and soft tissue infections. Both can stress the kidneys, and that additive strain accounts for one of the three major ratings among 56 supplements here, enough that this list warrants real care.”

About Evodia

What is Evodia?

  • Digestive upset and nausea
  • Headaches
  • Menstrual cramps
  • Abdominal pain
  • Diarrhea

Evodia is a fruit used in traditional Chinese medicine, most often for digestive complaints, headaches, and menstrual pain. Human evidence for these uses is very limited, and it is mostly studied in laboratory and animal research. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Tetradium ruticarpum · Rutaceae · Dried unripe fruit · Dried fruit, powder, capsules, tablets, teas, and traditional herbal formulas

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

Evodia: dosing

There is no well-established standard dose for evodia. Traditional use often relies on combination formulas prepared by trained practitioners, and modern supplement products vary widely in strength and ingredients.If you choose to use evodia, follow the directions on the product label and do not exceed the recommended amount.

About Dicloxacillin

What Is Dicloxacillin Used For?

Brand names: Dynapen, Pathocil, Dycill, Pathocil Injection

Dicloxacillin sodium capsules treat infections caused by staphylococci (staph bacteria) that make penicillinase and are shown to be susceptible to the drug. Penicillinase is an enzyme that destroys many penicillins.

Your prescriber may start it before lab results are back if a resistant staph infection is suspected. It should not be used for infections caused by bacteria that regular penicillin G can treat. If tests show a different type of bacteria, it should be stopped.

Taking Evodia and Dicloxacillin Sodium Together: Common Questions

Is it safe to take Evodia with Dicloxacillin Sodium?
We do not list a known interaction between Evodia and Dicloxacillin Sodium. 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.
Should I take Evodia and Dicloxacillin Sodium at the same time of day?
At least one FDA label for a product containing Dicloxacillin Sodium 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 Dicloxacillin Sodium on its own and move Evodia 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 Evodia and Dicloxacillin Sodium combination checked?
Interactions in our licensed database are recorded against drug classes. Dicloxacillin Sodium is filed under 5 classifications, and Evodia has documented interactions with 11 drug classes — none of Dicloxacillin Sodium'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 Evodia interact with any other medications?
Yes. Evodia has 950 documented drug interactions in our database — Dicloxacillin Sodium 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 Dicloxacillin Sodium interact with any supplements?
Yes. Dicloxacillin Sodium has documented interactions with 56 supplements in our database — Evodia is not one of them. The Dicloxacillin Sodium interaction page linked on this page lists every one, ranked by severity.
