Interaction report

Sea Buckthorn and Ozanimod Hydrochloride

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 Ozanimod Hydrochloride and Sea Buckthorn 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.

Sea Buckthorn safety at a glance

Sea Buckthorn overall Use caution Generally well tolerated as a food, but supplement safety has not been fully studied.
Pregnancy Use caution Food amounts are likely fine, but supplement doses are not well studied, so use caution and ask your doctor.
Breastfeeding Use caution Not enough reliable safety data on supplement use while breastfeeding; use caution.

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

How we checked

Why No Interaction Is Listed for Ozanimod Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ozanimod Hydrochloride is filed under 6 classifications — including monoamine oxidase inhibitors (maois), cytochrome p450 2c8 (cyp2c8) substrates, immunosuppressants. Sea Buckthorn has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (moderate) — and none of Ozanimod Hydrochloride’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

What Sea Buckthorn Itself Has Been Linked To

This is not an interaction — nothing below involves Ozanimod Hydrochloride. It is the side-effect record for Sea Buckthorn on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Sea Buckthorn, this list is the first place to look.

  • Itching / A skin rash Additional detail

    “Orally, high doses of sea buckthorn may cause yellow staining of the skin. One case of generalized yellow skin has been reported for a patient who consumed sea buckthorn 100 grams daily for 6 months. Topically, sea buckthorn oil has been associated with dryness, irritation, redness, and rash. Rash occurred in 4% of patients in one clinical study.”

Everything above comes from the Natural Medicines adverse-effect record for Sea Buckthorn — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Ozanimod Hydrochloride’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Ozanimod Hydrochloride column appears here.

About Sea Buckthorn

What is Sea Buckthorn?

Sea Buckthorn
  • Skin health and dryness
  • Dry eye symptoms
  • Digestive complaints
  • Heart and cholesterol support
  • General antioxidant and immune support

Sea buckthorn is a berry-bearing shrub rich in vitamins, carotenoids, and fatty acids that people use for skin, eye, digestive, and heart health. Early research is promising for a few uses like dry skin and dry eye, but most claims are not yet proven. It is generally well tolerated as a food, but talk to your pharmacist before using concentrated supplements.

Hippophae rhamnoides · Elaeagnaceae · Berries (fruit), seeds, seed and fruit oil, and sometimes leaves · Capsules, softgels, oil (seed or fruit), juice, powder, teas, topical creams and ointments

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

Sea Buckthorn: dosing

There is no official or standardized dose of sea buckthorn. The right amount depends on the product, its form (oil, capsule, juice, or powder), and how it is concentrated.The best approach is to follow the directions on the product label and not exceed the recommended amount.
