Calea Zacatechichi + Dicloxacillin Sodium

Dicloxacillin Sodium brand names: Dynapen, Pathocil, Dycill, Pathocil Injection.

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 Calea Zacatechichi 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, 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

Calea Zacatechichi 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 Calea Zacatechichi 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.

Calea Zacatechichi safety at a glance

Calea Zacatechichi overall Use caution It has a long folk-use history but little modern safety data, and it can cause nausea and vomiting.

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

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. Calea Zacatechichi has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (minor) and cns depressants (minor) — 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

No Interaction Found — But Data Suggests Calea Zacatechichi and Dicloxacillin Sodium 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.

Reported for Calea Zacatechichi but not commonly for Dicloxacillin Sodium: drowsiness.

Effects for Dicloxacillin Sodium come from the ADVERSE REACTIONS section of its FDA label; effects for Calea Zacatechichi come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 195 voluntary FDA FAERS reports for Dicloxacillin Sodium 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.

How to take them

Some Dicloxacillin Sodium Products Have a Food Rule — Calea Zacatechichi 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 — Calea Zacatechichi 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 Calea Zacatechichi 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. 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.

Everything else you take

See Every Supplement That Interacts With Dicloxacillin Sodium

This page covers Calea Zacatechichi 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 Calea Zacatechichi

What is Calea Zacatechichi?

  • Promoting vivid or lucid dreams
  • Sleep and relaxation
  • Digestive upset
  • Fever
  • Traditional ritual use

Calea zacatechichi, often called 'dream herb,' is a Mexican plant traditionally used to encourage vivid dreams and to treat digestive complaints and fever. Human research is very limited, so its benefits are not well proven, and its safety has not been carefully studied. It tastes very bitter, can cause nausea, and should be avoided during pregnancy and breastfeeding.

Calea ternifolia · Asteraceae · Leaves and flowering tops (dried) · Dried leaf tea, capsules, tincture/liquid extract, and smoked dried leaf

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

Calea Zacatechichi: dosing

There is no established or standardized dose for Calea zacatechichi. The amount of active compounds can vary a lot from product to product, which makes safe dosing hard to judge.If you choose to use it, follow the directions on the product label and do not exceed them.

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 Calea Zacatechichi and Dicloxacillin Sodium Together: Common Questions

Is it safe to take Calea Zacatechichi with Dicloxacillin Sodium?
We do not list a known interaction between Calea Zacatechichi 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.
Do Calea Zacatechichi and Dicloxacillin Sodium have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Calea Zacatechichi 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 Calea Zacatechichi 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 Calea Zacatechichi and Dicloxacillin Sodium combination checked?
Interactions in our licensed database are recorded against drug classes. Dicloxacillin Sodium is filed under 5 classifications, and Calea Zacatechichi has documented interactions with 2 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 Calea Zacatechichi interact with any other medications?
Yes. Calea Zacatechichi has 334 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 — Calea Zacatechichi is not one of them. The Dicloxacillin Sodium interaction page linked on this page lists every one, ranked by severity.
