Drug & supplement interaction

Hesperidin + Clemastine

Clemastine brand name: Tavist Allergy.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Hesperidin and Clemastine 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

Hesperidin and Clemastine

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 Clemastine and Hesperidin 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 Clemastine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Clemastine is filed under 4 classifications — including anticholinergic drugs, photosensitizing drugs, seizure threshold lowering drugs. Hesperidin has documented interactions with 7 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antihypertensive drugs (moderate) and celiprolol (celicard) (moderate) — and none of Clemastine’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 Hesperidin and Clemastine 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.

Special populations

Hesperidin 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 100 mg daily for 30 days in combination with diosmin. 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.

From our pharmacist’s overview on the Clemastine page

“Clemastine (Tavist Allergy) is an older, sedating antihistamine that already dries the mouth, blurs vision, and slows the gut, and that is exactly why this list earns real caution rather than a quick skim. Thirty of the 72 supplements on file pile the same drying, sedating anticholinergic load on top, and two of the three major-rated e…”

About Hesperidin

What is Hesperidin?

Hemorrhoids
Varicose veins and poor circulation
Leg swelling (venous insufficiency)
High blood pressure
Antioxidant support

Hesperidin is a flavonoid found in citrus fruits that is often combined with diosmin and used for vein and circulation problems like hemorrhoids and varicose veins. Some evidence supports these uses, but data for many other claims is limited. It is generally well tolerated, but pregnant and breastfeeding people should avoid it because safety has not been established.

Rutaceae · Fruit and peel of citrus fruits (especially oranges and lemons) · Capsules, tablets, often combined with diosmin or vitamin C as a bioflavonoid complex

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

Hesperidin: dosing

There is no official standardized dose of hesperidin. The amount used in research varies depending on the product and whether it is combined with diosmin or other ingredients.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Clemastine treats symptoms of allergic rhinitis (hay fever and similar nasal allergies) — including sneezing, runny nose, itching, and watery eyes. The oral solution (Clemastine Fumarate syrup) is indicated for adults and children aged 6 through 12 years. The tablets (Clemastine Fumarate and Clemsza) are indicated for adults.

Clemastine also treats mild, uncomplicated allergic skin reactions — specifically urticaria (hives) and angioedema (swelling under the skin) — at the appropriate dosage level, in both the oral solution and tablet forms.

Taking Hesperidin and Clemastine Together: Common Questions

Is it safe to take Hesperidin with Clemastine?

We do not list a known interaction between Hesperidin and Clemastine. 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 Hesperidin and Clemastine 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 Hesperidin and Clemastine combination checked?

Interactions in our licensed database are recorded against drug classes. Clemastine is filed under 4 classifications, and Hesperidin has documented interactions with 7 drug classes — none of Clemastine'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 Hesperidin interact with any other medications?

Yes. Hesperidin has 702 documented drug interactions in our database — Clemastine 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 Clemastine interact with any supplements?

Yes. Clemastine has documented interactions with 72 supplements in our database — Hesperidin is not one of them. The Clemastine interaction page linked on this page lists every one, ranked by severity.
