Drug & supplement interaction

Sea Buckthorn + Desloratadine

Desloratadine brand name: Clarinex.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Sea Buckthorn and Desloratadine 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.

Sea Buckthorn and Desloratadine

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 Desloratadine 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 Desloratadine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Desloratadine is filed under 2 classifications — seizure threshold lowering drugs, oral drugs. Sea Buckthorn has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (moderate) — and none of Desloratadine’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 Sea Buckthorn and Desloratadine 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.

  • Itching / A skin rash reported in 4.1% of FDA reports for Desloratadine Additional detail

    Sea Buckthorn

    “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.”

    Desloratadine

    Listed in the ADVERSE REACTIONS section of the FDA label for Desloratadine, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Effects for Desloratadine come from the ADVERSE REACTIONS section of its FDA label; effects for Sea Buckthorn come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 10,700 voluntary FDA FAERS reports for Desloratadine 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.

From our pharmacist’s overview on the Desloratadine page

“An allergy pill only helps if it gets absorbed, and most of desloratadine's (Clarinex) supplement interactions come down to exactly that. Bulk-forming fibers, gums, and charcoal products can trap the medication in the gut, with activated charcoal the standout, the sole major rating here and one I would not take near a dose.”

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.

Taking Sea Buckthorn and Desloratadine Together: Common Questions

Is it safe to take Sea Buckthorn with Desloratadine?
We do not list a known interaction between Sea Buckthorn and Desloratadine. 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 Sea Buckthorn and Desloratadine have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Sea Buckthorn and Desloratadine combination checked?
Interactions in our licensed database are recorded against drug classes. Desloratadine is filed under 2 classifications, and Sea Buckthorn has documented interactions with 2 drug classes — none of Desloratadine'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 Sea Buckthorn interact with any other medications?
Yes. Sea Buckthorn has 289 documented drug interactions in our database — Desloratadine 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 Desloratadine interact with any supplements?
Yes. Desloratadine has documented interactions with 23 supplements in our database — Sea Buckthorn is not one of them. The Desloratadine interaction page linked on this page lists every one, ranked by severity.
