Drug & supplement interaction

Saffron + Eltrombopag

Eltrombopag brand names: Promacta, Revolade, Alvaiz.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Saffron and Eltrombopag 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 Eltrombopag states a food rule worth keeping to, and 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.

Saffron and Eltrombopag

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 Eltrombopag and Saffron 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.

Saffron safety at a glance

Saffron overall Use caution Likely safe in food amounts, but supplement doses should be used carefully and high doses can be toxic.
Pregnancy Likely Unsafe When used orally in amounts exceeding those commonly found in foods. Larger amounts of saffron have uterine stimulant and abortifacient effects; avoid using. Read the full pregnancy detail
Breastfeeding Use caution Not enough reliable safety information, so it is best to avoid supplement amounts.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Eltrombopag

Interactions in our licensed database are recorded against drug classes, not just single drug names. Eltrombopag is filed under 2 classifications — hepatotoxic drugs, oral drugs. Saffron has documented interactions with 4 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and caffeine (moderate) — and none of Eltrombopag’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 Saffron and Eltrombopag 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. One of them is worth acting on rather than waiting out — marked below.

  • Bleeding or bruising Worth acting on Additional detail

    Saffron

    “Orally, saffron extract has been reported to cause decreases in platelet, white blood cell, and red blood cell counts after 7 days to 12 weeks of use with doses of 60-200 mg daily. Many of these decreases were only significant when compared to baseline but did not maintain significance when compared to placebo.”

How to take them

Some Eltrombopag Products Have a Food Rule — Saffron Should Not Break It

At least one FDA label for a product containing Eltrombopag says to take it with food. If you take Saffron on an empty stomach out of habit, keep them separate — and take Eltrombopag 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 Eltrombopag 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.

Do not split, chew, or crush tablets and mix with food or liquids.

From the Dosage and Administration section of the FDA label we read for Eltrombopag — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

See Every Supplement That Interacts With Eltrombopag

This page covers Saffron only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Eltrombopag page lists 55 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Ashwagandha (moderate).

By severity: 4 major · 42 moderate · 9 minor.

From our pharmacist’s overview on the Eltrombopag page

“Eltrombopag (Promacta, Revolade) boosts platelet production, and because the drug itself can stress the liver, this list warrants genuine care. Thirty-eight of the 55 supplements and herbs here can injure the liver on their own, so combining them stacks risk on an organ your doctor is already watching with blood tests.”

About Saffron

What is Saffron?

Saffron
  • Depression and low mood
  • Anxiety
  • PMS symptoms
  • Memory and cognition
  • Eye health (age-related macular degeneration)

Saffron is a costly spice that has shown promise in early studies for mild-to-moderate depression and some mood and PMS symptoms, but most research uses small trials, so results are not definitive. It is generally well tolerated in food and small supplement amounts, but high doses can be harmful and it should be avoided in pregnancy. Talk to your pharmacist or doctor before using saffron supplements.

Crocus sativus · Iridaceae · Dried stigmas of the flower · Capsules, tablets, dried spice, extracts, tea

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

Saffron: dosing

There is no official, standardized dose of saffron for any health condition. Many supplement studies have used standardized extracts, but products vary widely in strength and quality.The best approach is to follow the directions on the product label and not exceed the recommended amount. Because high doses can be harmful, more is not better with saffron.

About Eltrombopag

What Is Eltrombopag Used For?

Brand names: Promacta, Revolade, Alvaiz

Eltrombopag treats thrombocytopenia (low platelet counts) in several different conditions. It is used for adults and children (age 1 and older, depending on the product) with persistent or chronic immune thrombocytopenia (ITP) — a condition where the immune system destroys platelets — when other treatments like steroids or immunoglobulins haven't worked well enough. It is also used to raise platelet counts in adults with chronic hepatitis C whose low platelet count prevents them from starting or staying on interferon-based antiviral therapy.

Eltrombopag tablets (including Promacta) are also approved — alone or combined with immunosuppressive therapy — for adults and certain children (age 2 and older) with severe aplastic anemia, a serious bone marrow failure condition. Alvaiz (a specific brand) shares most of these uses but has product-specific dosing that is not interchangeable milligram-for-milligram with other eltrombopag products. The oral suspension formulation is approved for ITP and for refractory severe aplastic anemia, but is not approved for first-line severe aplastic anemia in combination with immunosuppressive therapy.

Taking Saffron and Eltrombopag Together: Common Questions

Is it safe to take Saffron with Eltrombopag?
We do not list a known interaction between Saffron and Eltrombopag. 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 Saffron and Eltrombopag 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.
Should I take Saffron and Eltrombopag at the same time of day?
At least one FDA label for a product containing Eltrombopag says to take it with food. If you take Saffron on an empty stomach out of habit, keep them separate and take Eltrombopag with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Eltrombopag products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Saffron and Eltrombopag combination checked?
Interactions in our licensed database are recorded against drug classes. Eltrombopag is filed under 2 classifications, and Saffron has documented interactions with 4 drug classes — none of Eltrombopag'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 Saffron interact with any other medications?
Yes. Saffron has 521 documented drug interactions in our database — Eltrombopag 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 Eltrombopag interact with any supplements?
Yes. Eltrombopag has documented interactions with 55 supplements in our database — Saffron is not one of them. The Eltrombopag interaction page linked on this page lists every one, ranked by severity.
