Drug & supplement interaction

Vitex Agnus-castus + Meclofenamate

Meclofenamate brand name: Meclomen.

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 Vitex Agnus-castus and Meclofenamate 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 Meclofenamate 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

Vitex Agnus-castus and Meclofenamate

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 Meclofenamate and Vitex Agnus-castus 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 Meclofenamate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Meclofenamate is filed under 5 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Vitex Agnus-castus has documented interactions with 5 drug classes — the most serious being antipsychotic drugs (moderate), contraceptive drugs (moderate) and dopamine agonists (moderate) — and none of Meclofenamate’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 Vitex Agnus-castus and Meclofenamate 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.

Vitex Agnus-castus in Pregnancy & Breastfeeding

Pregnancy And Lactation Possibly Unsafe

When used orally. Theoretically, the hormonal effects of vitex agnus-castus might adversely affect pregnancy or lactation. Animal research shows that taking vitex agnus-castus fruit extract when planning to become pregnant or during pregnancy may increase the risk of infertility, low fetal body weight, abortion, and stillbirth; avoid using.

How to take them

Some Meclofenamate Products Have a Food Rule — Vitex Agnus-castus Should Not Break It

At least one FDA label for a product containing Meclofenamate says to take it with food. If you take Vitex Agnus-castus on an empty stomach out of habit, keep them separate — and take Meclofenamate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Meclofenamate 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.

If gastrointestinal complaints occur (see WARNINGS and PRECAUTIONS ), meclofenamate sodium may be administered with meals or with milk (see CLINICAL PHARMACOLOGY for a description of food effects).

From the Dosage and Administration section of the FDA label we read for Meclofenamate — 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.

Overlapping uses

What Meclofenamate Is Prescribed For, and What Vitex Agnus-castus Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Meclofenamate is a prescription medicine with approved uses on its FDA label. Vitex Agnus-castus is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Meclofenamate is prescribed for: Meclofenamate sodium capsules are used in adults to relieve mild to moderate pain, reduce fever, and treat the signs and symptoms of rheumatoid arthritis, osteoarthritis, juvenile arthritis, and ankylosing spondylitis (a type of spinal arthritis). They are also used for acute painful shoulder, acute gouty arthritis, primary dysmenorrhea (painful periods), and idiopathic heavy menstrual bleeding. This medication is not recommended for use in children, as adequate safety and effectiveness studies have not been carried out in that age group.

Vitex Agnus-castus has been studied for:

  • Dysmenorrhea studied, not established Vitex Agnus-castus has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Vitex Agnus-castus for dysmenorrhea

    It is unclear if oral vitex agnus-castus is beneficial in patients with dysmenorrhea.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Meclofenamate on your own; if you are taking Vitex Agnus-castus for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Vitex Agnus-castus

What is Vitex Agnus-castus?

Vitex Agnus-castus
  • Premenstrual syndrome (PMS)
  • Irregular or absent menstrual periods
  • Cyclical breast pain (mastalgia)
  • Menopause symptoms
  • Fertility support

Vitex (chasteberry) is an herbal remedy most often used for PMS and menstrual cycle problems, and the strongest evidence is for easing some PMS symptoms. It is generally well tolerated by many adults, but it can affect hormone-related processes, so anyone who is pregnant, breastfeeding, or has a hormone-sensitive condition should talk with a healthcare professional first.

Vitex agnus-castus · Lamiaceae · Dried ripe fruit (berries) · Capsules, tablets, liquid extracts (tinctures), and teas

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

Vitex Agnus-castus: dosing

There is no single official or proven dose for vitex. Products differ widely in how they are made and how concentrated they are, so the amount per dose varies from one brand to another. Standardized extracts are common, but a universal best dose has not been established.The safest approach is to follow the directions on the product label and not take more than recommended. Because vitex may take several weeks or even a few menstrual cycles before any effect is noticed, it is often used over time.

Taking Vitex Agnus-castus and Meclofenamate Together: Common Questions

Is it safe to take Vitex Agnus-castus with Meclofenamate?
We do not list a known interaction between Vitex Agnus-castus and Meclofenamate. 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 Vitex Agnus-castus and Meclofenamate have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Vitex Agnus-castus and Meclofenamate at the same time of day?
At least one FDA label for a product containing Meclofenamate says to take it with food. If you take Vitex Agnus-castus on an empty stomach out of habit, keep them separate and take Meclofenamate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Meclofenamate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Vitex Agnus-castus and Meclofenamate used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Vitex Agnus-castus in each. That is a conversation for your prescriber, especially if Meclofenamate is being adjusted to a target.
How was the Vitex Agnus-castus and Meclofenamate combination checked?
Interactions in our licensed database are recorded against drug classes. Meclofenamate is filed under 5 classifications, and Vitex Agnus-castus has documented interactions with 5 drug classes — none of Meclofenamate'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 Vitex Agnus-castus interact with any other medications?
Yes. Vitex Agnus-castus has 121 documented drug interactions in our database — Meclofenamate 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 Meclofenamate interact with any supplements?
Yes. Meclofenamate has documented interactions with 32 supplements in our database — Vitex Agnus-castus is not one of them. The Meclofenamate interaction page linked on this page lists every one, ranked by severity.
