Drug & supplement interaction

Salvia Divinorum + Cefdinir

Cefdinir brand name: Omnicef.

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 Salvia Divinorum and Cefdinir 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.

Salvia Divinorum and Cefdinir

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 Cefdinir and Salvia Divinorum 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Salvia Divinorum at all — not against Cefdinir, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Salvia Divinorum safety at a glance

Salvia Divinorum overall Avoid It is a potent hallucinogen with no established medical use and limited safety data; it is also restricted or illegal in many areas.
Pregnancy Avoid There is no safety data, and a hallucinogen should not be used during pregnancy.
Breastfeeding Avoid There is no safety data, so it should be avoided while breastfeeding.

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

What to actually watch for

No Interaction Found — But Data Suggests Salvia Divinorum and Cefdinir 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.

  • Tiredness / Dizziness reported in 6.1% of FDA reports for Cefdinir Additional detail

    Salvia Divinorum

    “Orally or by inhalation, Salvia divinorum can cause hallucinogenic effects. These include restlessness, hyperactivity, disorientation, loss of coordination, dizziness, slurred speech, altered perceptions, changes in perception of body temperature, personal detachment or distorted body ownership, fatigue, severe mood changes, and psychosis. Most of these effects resolve within 20 minutes;”

    “Neurologic changes caused by Salvia divinorum are rapid, intense, and short-lived. Most evidence suggests a peak effect within 2 minutes following consumption by smoking, with a slower peak when consumed orally. Most symptoms cease within 20 minutes; however, the 'high' can last as long as 2 hours.”

Reported for Salvia Divinorum but not commonly for Cefdinir: unsteadiness, confusion, hallucinations and anxiety or restlessness.

See Every Supplement That Interacts With Cefdinir

This page covers Salvia Divinorum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefdinir page lists 60 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), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefdinir page

“Cefdinir (Omnicef) is a short-course antibiotic for ear, sinus, throat, and skin infections, and three of its 60 supplement interactions on file are rated major and deserve genuine care. Two herbs, Siberian cocklebur and asarabacca, can damage the kidneys, an added strain nobody needs while fighting an infection.”

About Salvia Divinorum

What is Salvia Divinorum?

  • Hallucinogenic or psychedelic experiences
  • Spiritual or ritual practices
  • Recreational use
  • Traditional Mazatec healing ceremonies

Salvia divinorum is a powerful hallucinogenic plant traditionally used by the Mazatec people of Mexico and now used recreationally for its short but intense mind-altering effects. There is no proven medical use, the safety is poorly studied, and it is illegal or restricted in many places. Because its effects can be unpredictable and disorienting, we do not recommend using it.

Salvia divinorum · Lamiaceae · Leaves · Dried leaves (smoked), chewed fresh leaves, leaf extracts, tinctures

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

Salvia Divinorum: dosing

There is no established or recommended safe dose for Salvia divinorum. The strength of leaves and extracts varies widely, and concentrated products can be far more potent than plain leaves, making effects hard to predict.Because it is not a proven medicine and is restricted in many areas, we cannot recommend any specific amount.

About Cefdinir

What Is Cefdinir Used For?

Brand name: Omnicef

Cefdinir treats mild to moderate bacterial infections in adults, adolescents, and children caused by susceptible bacteria. It is used for community-acquired pneumonia, acute exacerbations of chronic bronchitis, acute maxillary sinusitis (sinus infection), pharyngitis/tonsillitis (strep throat), and uncomplicated skin and skin structure infections.

In pediatric patients (ages 6 months through 12 years), cefdinir is also used to treat acute bacterial otitis media (middle ear infection). It should only be used for infections that are proven or strongly suspected to be caused by bacteria — not for viral illnesses like the common cold.

Most-Reported Side Effects for Cefdinir

From FAERS, the FDA’s public side-effect reporting system (7,629 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 530 reports
Chronic kidney disease 485 reports
Pneumonia 482 reports
Fatigue 462 reports
Nausea 400 reports

Taking Salvia Divinorum and Cefdinir Together: Common Questions

Is it safe to take Salvia Divinorum with Cefdinir?
We do not list a known interaction between Salvia Divinorum and Cefdinir. 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 Salvia Divinorum and Cefdinir have any of the same side effects?
Yes — our sources link each of them separately to 4 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.
Does Cefdinir interact with any supplements?
Yes. Cefdinir has documented interactions with 60 supplements in our database — Salvia Divinorum is not one of them. The Cefdinir interaction page linked on this page lists every one, ranked by severity.
