Drug & supplement interaction

Pokeweed + Azithromycin

Azithromycin brand names: Zithromax, Zmax, Azasite.

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 Pokeweed and Azithromycin 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.

Pokeweed and Azithromycin

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 Azithromycin and Pokeweed 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 Pokeweed at all — not against Azithromycin, 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.

What to actually watch for

No Interaction Found — But Data Suggests Pokeweed and Azithromycin 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on Additional detail

    “Pokeweed is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Orally, all parts of the pokeweed plant can cause nausea, vomiting, cramping, abdominal pain, diarrhea, a burning sensation in the mouth and throat, weakness, hypotension, bloody emesis, bloody diarrhea, tachycardia, difficulty breathing, salivation, urinary incontinence, spasms, convulsions, severe thirst…”

Effects for Azithromycin come from the ADVERSE REACTIONS section of its FDA label; effects for Pokeweed come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 59,712 voluntary FDA FAERS reports for Azithromycin 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.

See Every Supplement That Interacts With Azithromycin

This page covers Pokeweed only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Azithromycin page lists 92 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), Arsenic (major), Cesium (major) and Ephedra (major).

By severity: 8 major · 71 moderate · 13 minor.

From our pharmacist’s overview on the Azithromycin page

“A five-day Z-Pak for a sinus or chest infection seems too brief to fuss over, but azithromycin (Zithromax, Zmax) deserves genuine caution around supplements, and the eight major-rated entries on this list are the ones to understand first. Most of those involve the heart.”

About Pokeweed

What is Pokeweed?

  • Joint pain and arthritis
  • Skin conditions
  • Swollen lymph nodes
  • Respiratory complaints
  • Traditional 'blood cleansing'

Pokeweed is a wild North American plant that is toxic in most of its raw forms, and there is no reliable evidence that it safely treats any condition. Poisonings have occurred from eating the berries, root, or improperly prepared greens. Because of its serious safety risks, most experts recommend avoiding it.

Phytolacca americana · Phytolaccaceae · Root, berries, leaves, and young shoots · Tincture, dried root, capsules, topical preparations, and traditionally cooked greens ('poke sallet')

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

Pokeweed: dosing

There is no established safe dose for pokeweed. Because the plant is toxic and the amount of active and harmful compounds varies widely, no reliable medicinal dose can be recommended.We do not provide dosing for pokeweed because of its poisoning risk. For most people, the safest choice is to avoid pokeweed altogether.

About Azithromycin

What Is Azithromycin Used For?

Brand names: Zithromax, Zmax, Azasite

  • Azithromycin is used to treat certain bacterial infections, such as bronchitis; pneumonia; sexually transmitted diseases (STD); and infections of the ears, lungs, sinuses, skin, throat, and reproductive organs. Azithromycin also is used to treat or prevent disseminated Mycobacterium avium complex (MAC) infection [a type of lung infection that often affects people with human immunodeficiency virus (HIV)]. Azithromycin is in a class of medications called macrolide antibiotics. It works by stopping the growth of bacteria.

  • Antibiotics such as azithromycin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Most-Reported Side Effects for Azithromycin

From FAERS, the FDA’s public side-effect reporting system (59,712 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 4,651 reports
Nausea 3,461 reports
Pneumonia 3,225 reports
Cough 3,120 reports

Taking Pokeweed and Azithromycin Together: Common Questions

Is it safe to take Pokeweed with Azithromycin?
We do not list a known interaction between Pokeweed and Azithromycin. 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 Pokeweed and Azithromycin have any of the same side effects?
Yes — our sources link each of them separately to 9 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 Azithromycin interact with any supplements?
Yes. Azithromycin has documented interactions with 92 supplements in our database — Pokeweed is not one of them. The Azithromycin interaction page linked on this page lists every one, ranked by severity.
