The bottom line No known interaction

We found no known interaction between Hazelnut and Avatrombopag Maleate 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 label for Avatrombopag Maleate states a food rule worth keeping to.

Hazelnut and Avatrombopag Maleate

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 Avatrombopag Maleate and Hazelnut 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Hazelnut at all — not against Avatrombopag Maleate, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Hazelnut Itself Has Been Linked To

This is not an interaction — nothing below involves Avatrombopag Maleate. It is the side-effect record for Hazelnut on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Hazelnut, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • A severe allergic reaction / An allergic reaction Worth acting on Additional detail

    “Orally, hazelnut is well tolerated.

    Serious Adverse Effects (Rare):

    All routes of administration: Allergic reactions, including oral allergy syndrome and anaphylaxis.”

    Hazelnut · Natural Medicines adverse-effect record, reported in allergic rhinitis (hay fever).

    “Orally, hazelnut can cause an allergic reaction in sensitive individuals, with severity ranging from oral allergy syndrome to anaphylaxis. The prevalence of hazelnut sensitization varies by geographic location, with hazelnut allergy reported more often in areas with greater birch tree pollen exposure. Hazelnut allergy is more common in adults than children, but children are more likely to develop severe reactions.”

  • A skin rash Additional detail

    “Orally, hazelnut can cause atopic dermatitis in patients with a hazelnut allergy. In one case, hazelnut essence in hydroxyzine syrup was determined to be the likely cause of atopic dermatitis in a toddler.”

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

How to take them

Some Avatrombopag Maleate Products Have a Food Rule — Hazelnut Should Not Break It

At least one FDA label for a product containing Avatrombopag Maleate says to take it with food. If you take Hazelnut on an empty stomach out of habit, keep them separate — and take Avatrombopag Maleate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Avatrombopag Maleate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Administer DOPTELET tablets and DOPTELET SPRINKLE with food.

From the Dosage and Administration section of the FDA label we read for Avatrombopag Maleate — where that label names a specific product, the instruction is that product's. See the Avatrombopag Maleate drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Avatrombopag Maleate page

“Avatrombopag maleate (Doptelet) exists to raise a low platelet count, so anything that drags its blood level down invites the bleeding risk it was prescribed to prevent. I would handle this list of 54 supplements with real care, and the two rated major come first.”

About Hazelnut

What is Hazelnut?

  • Heart and cholesterol health
  • Source of healthy fats and protein
  • Antioxidant support
  • Blood sugar support
  • General nutrition and snacking

Hazelnuts are a nutritious tree nut rich in healthy fats, fiber, vitamin E, and antioxidants, and eating them as part of a balanced diet may support heart health. They are mainly a food rather than a treatment, and the biggest safety concern is that they are a common cause of serious nut allergy.

Corylus avellana · Betulaceae · Nut (kernel), nut oil, and sometimes leaves · Whole nuts, hazelnut oil, hazelnut flour/meal, nut butter, and skin or leaf extracts in some supplements

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

Hazelnut: dosing

There is no official medical dose for hazelnuts. As a food, a small handful (about an ounce) is a common serving size in studies of nuts and heart health.For any hazelnut supplement, oil, or extract, there is no standardized dose.

From our Hazelnut monograph — the full record covers uses, side effects and every documented interaction.

About Avatrombopag

What Is Avatrombopag Used For?

Brand name: Doptelet

Avatrombopag treats thrombocytopenia (a low platelet count that raises bleeding risk) in three groups of patients. Doptelet tablets are used in adults with chronic liver disease who need their platelet count raised before a medical procedure, and in adults with chronic immune thrombocytopenia (ITP) whose platelet count has not responded well enough to earlier treatments. Doptelet tablets are also used in children aged 6 years and older with persistent or chronic ITP who have not responded to prior treatment.

Doptelet Sprinkle (oral granules) is specifically indicated for children aged 1 year to less than 6 years with persistent or chronic ITP who have not responded adequately to a previous treatment.
