Drug & supplement interaction

Diosmin + Semaglutide

Semaglutide brand names: Ozempic, Rybelsus, Wegovy.

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 Diosmin and Semaglutide 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.

Interaction report

Diosmin and Semaglutide

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 Semaglutide and Diosmin 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 Semaglutide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Semaglutide is filed under 2 classifications — antidiabetes drugs, oral drugs. Diosmin has documented interactions with 9 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), carbamazepine (tegretol) (moderate) and chlorzoxazone (parafon forte, paraflex) (moderate) — and none of Semaglutide’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Diosmin and Semaglutide 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.

Special populations

Diosmin in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally in amounts found in foods.

Pregnancy And Lactation Possibly Safe

When used orally in doses of up to 900 mg daily for 30 days in combination with other flavonoids, such as hesperidin. Some evidence suggests that taking this combination may be associated with placental insufficiency when used during the third trimester of pregnancy; however, the combination does not seem to induce fetal abnormalities, retard fetal growth, increase the risk of intrauterine death, or affect birth weight. Also, when breastfeeding, this combination does not seem to affect infant growth or feeding.

Overlapping uses

What Semaglutide Is Prescribed For, and What Diosmin Has Been Studied For

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

Semaglutide is prescribed for: Semaglutide is available as Wegovy (injection and tablet) and Ozempic (injection), and each product has its own approved uses. Wegovy injection is approved — alongside diet and exercise — to reduce excess body weight in adults and in children aged 12 and older with obesity, to lower the risk of serious heart events (heart attack, stroke, or cardiovascular death) in adults with obesity or overweight who also have established heart disease, and for treatment of a liver condition called MASH (metabolic dysfunction-associated steatohepatitis, formerly called NASH) with moderate-to-advanced scarring in adults. Wegovy tablets share the cardiovascular risk reduction and weight management uses in adults, but are not approved for MASH or for use in children. Ozempic injection is approved to improve blood sugar control in adults with type 2 diabetes (alongside diet and exercise) and to reduce the risk of major cardiovascular events in adults with type 2 diabetes who also have established heart disease.

Read the rest of what Semaglutide is prescribed for

All forms are used alongside a reduced-calorie diet and increased physical activity. Ozempic is not approved for type 1 diabetes. The MASH approval for Wegovy injection is an accelerated approval, meaning continued approval may depend on results from a confirmatory study.

Diosmin has been studied for:

  • Diabetes studied, not established Diosmin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Diosmin for diabetes

    It is unclear if oral diosmin, as part of a micronized purified flavonoid fraction or in combination with other compounds, is beneficial for diabetes.

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 Semaglutide on your own; if you are taking Diosmin for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Semaglutide page

“Semaglutide (Ozempic, Rybelsus, Wegovy) lowers blood sugar, and so do most of the 256 supplements on this page, which is why I read this list with real vigilance rather than a shrug. Nearly all of the entries either add to its glucose-lowering effect and raise the risk of hypoglycemia, or push sugar the other way and blunt it, as niaci…”

About Diosmin

What is Diosmin?

  • Chronic venous insufficiency
  • Hemorrhoids
  • Leg swelling and heaviness
  • Varicose veins
  • Spider veins

Diosmin is a citrus-derived flavonoid most often used for vein-related problems such as chronic venous insufficiency and hemorrhoids, and it is usually combined with a related flavonoid called hesperidin. Some studies suggest it may help relieve leg swelling and hemorrhoid symptoms, but quality varies. Talk to your pharmacist or doctor before starting it, especially if you are pregnant or breastfeeding.

A flavonoid derived from citrus fruit peels (often made from hesperidin) · Tablets, capsules (often combined with hesperidin)

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

Diosmin: dosing

There is no single official dose of diosmin for supplement use. Do not assume that taking more will work better or be safer.

Taking Diosmin and Semaglutide Together: Common Questions

Is it safe to take Diosmin with Semaglutide?
We do not list a known interaction between Diosmin and Semaglutide. 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 Diosmin and Semaglutide have any of the same side effects?
Yes — our sources link each of them separately to 8 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.
Are Diosmin and Semaglutide 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 Diosmin in each. That is a conversation for your prescriber, especially if Semaglutide is being adjusted to a target.
How was the Diosmin and Semaglutide combination checked?
Interactions in our licensed database are recorded against drug classes. Semaglutide is filed under 2 classifications, and Diosmin has documented interactions with 9 drug classes — none of Semaglutide'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 Diosmin interact with any other medications?
Yes. Diosmin has 884 documented drug interactions in our database — Semaglutide 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 Semaglutide interact with any supplements?
Yes. Semaglutide has documented interactions with 256 supplements in our database — Diosmin is not one of them. The Semaglutide interaction page linked on this page lists every one, ranked by severity.
