Drug & supplement interaction

Sweet Clover + Brexpiprazole

Brexpiprazole brand name: Rexulti.

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 Sweet Clover and Brexpiprazole 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.

Sweet Clover and Brexpiprazole

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 Brexpiprazole and Sweet Clover 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.

Sweet Clover safety at a glance

Sweet Clover overall Use caution Generally used in small amounts, but its coumarin content can affect bleeding and the liver, so use cautiously.
Pregnancy Avoid Not enough safety information is available, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety is unknown while breastfeeding, so it is best avoided.

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

How we checked

Why No Interaction Is Listed for Brexpiprazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Brexpiprazole is filed under 8 classifications — including dopamine agonists, antipsychotic drugs, serotonergic drugs. Sweet Clover has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and hepatotoxic drugs (moderate) — and none of Brexpiprazole’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.

No Interaction Found — But Data Suggests Sweet Clover and Brexpiprazole May Share a Side Effect

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.

    Brexpiprazole

    Listed in the ADVERSE REACTIONS section of the FDA label for Brexpiprazole. Read the label on DailyMed ›

Reported for Sweet Clover but not commonly for Brexpiprazole: liver problems and bleeding or bruising.

Effects for Brexpiprazole come from the ADVERSE REACTIONS section of its FDA label; effects for Sweet Clover come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 16,505 voluntary FDA FAERS reports for Brexpiprazole 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.

About Sweet Clover

What is Sweet Clover?

Sweet Clover
  • Varicose veins and poor circulation
  • Leg swelling (edema)
  • Hemorrhoids
  • Bruising and minor inflammation
  • Respiratory complaints

Sweet clover is a traditional European herb most often promoted for vein problems and leg swelling, but high-quality human evidence is limited. It contains coumarin, which can become dangerous if the plant spoils, so quality matters and you should talk to a pharmacist before using it.

Melilotus officinalis · Fabaceae · Above-ground parts (flowering tops, leaves, and stems) · Tea, dried herb, capsules, tincture, topical creams and ointments

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

Sweet Clover: dosing

There is no well-established standard dose for sweet clover. Traditional use varies widely depending on whether it is taken as a tea, tincture, or capsule, and the coumarin content of different products can differ a lot.The safest approach is to follow the directions on the product label and not exceed them.

Taking Sweet Clover and Brexpiprazole Together: Common Questions

Is it safe to take Sweet Clover with Brexpiprazole?
We do not list a known interaction between Sweet Clover and Brexpiprazole. 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 Sweet Clover and Brexpiprazole have any of the same side effects?
Yes — our sources link each of them separately to one 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.
How was the Sweet Clover and Brexpiprazole combination checked?
Interactions in our licensed database are recorded against drug classes. Brexpiprazole is filed under 8 classifications, and Sweet Clover has documented interactions with 2 drug classes — none of Brexpiprazole'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 Sweet Clover interact with any other medications?
Yes. Sweet Clover has 480 documented drug interactions in our database — Brexpiprazole 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 Brexpiprazole interact with any supplements?
Yes. Brexpiprazole has documented interactions with 177 supplements in our database — Sweet Clover is not one of them. The Brexpiprazole interaction page linked on this page lists every one, ranked by severity.
